1. General and Safety Instructions 

1.1 General 

This Operation & Maintenance Manual contains basic information to be noted during installation, 

operation and maintenance. It is therefore essential that the contractor read the 

manual before installing and commissioning the pump/system as well as by the relevant 

operating personnel/owner of the pump/system. It must remain accessible at the dosing 

pump/system for reference at all times. 

In addition to the general safety instructions under this main heading of Safety, the special 

safety precautions outlined another section must also be observed. 

1.2 Warning symbols used in this Operation & Maintenance Manual 

This Operation & Maintenance Manual contains vital information, which may endanger 

people, the environment and the dosing pump/system if disregarded. These statements 

are identified by the following symbols: 

DANGER! Refers to an imminent danger. Non-compliance can lead to death or serious 

injury. 

WARNING! Refers to a potentially hazardous situation. Non-compliance can lead to death 

or serious injury. 

CAUTION! Refers to a potentially hazardous situation. Non-compliance can lead to minor 

injury or property damage.

endanger the pump/system and its operation if disregarded. 

IMPORTANT! Draws attention to supplementary information to make the work easier and 

ensure trouble free operation. 

1.3 Qualification and training of personnel 

The personnel employed for installation, operation, inspection and maintenance work 

must be qualified to do so. The areas of responsibility, competence and supervision of the 

personnel must be precisely defined by the owner. Personnel who do not have the required 

knowledge must be duly rained and instructed. If necessary, this training can also be 

provided by the manufacturer/supplier on behalf of the dosing pump’s owner. In addition, 

the owner of the system must ensure that the relevant personnel are fully familiar with and 

have understood the contents of this Operation & Maintenance Manual.

always be followed, including the following: 

1.) Read and follow all instructions! 

2.) WARNING! To reduce risk of injury, do not permit children to use this product 

unless they are closely supervised at all times. 

WARNING! 

| Operating Manual TOPAX DE | General and Safety Instructions

3.) WARNING! Risk of electric shock. Connect only to a grounding type receptacle 

protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician 

if you cannot verify that the receptacle is protected by a GFCI. 

4.) Do not bury the cord. Locate the cord to minimize abuse from lawn mowers, hedge 

trimmers, and other equipment. 

WARNING! 

5.) WARNING! To reduce the risk of electric shock, replace damaged cord immediately. 

6.) WARNING! To reduce the risk of electric shock, do not use an extension cord 

to connect the unit to the electricity supply; provide a properly located outlet. 

7.) Save these instructions! 

1.5 Hazards due to non-compliance with safety instructions 

Failure to comply with safety instructions may endanger not only people, but also the environment 

and the dosing pump/system. Non-compliance with the safety instructions can 

lead to the loss of all entitlement to damages. The following hazard in particular may arise: 

- Danger to people due to electrical, mechanical and chemical effects. - Failure of system 

functions. - Danger to the environment due to leakage of hazardous substances. - 

WARNING! 

WARNING! 

1.6 Safe operation 

The safety instructions in this Operation & Maintenance Manual must be observed. 

The owner is responsible for ensuring the compliance with local safety regulations. 

1.7 Safety instructions for the owner/operator 

Leakages (e.g. due to ruptures in the lining) of hazardous substances (e.g. toxic or 

abrasive) must be discharged in such a way as to exclude all danger to people and the 

environment. Statutory regulations must be observed. 

Danger due to electric current must be excluded (for further details, refer to the German 

VDE standards as well as local regulations or chapter 1.4). 

1.8 Safety instructions for inspection-, maintenance-, and installation work 

The owner must ensure that all inspection, maintenance and installation work is undertaken 

by authorized and duly qualified personnel who have also studied this Operation & 

Maintenance Manual. 

The dosing pump must always come to a complete stop before starting any work on the 

pump. The procedure specified in this Operation & Maintenance Manual for shutting down 

the Dosing/pump/system must be observed without fail. 

Dosing pumps or systems in contact with potentially harmful media must be decontaminated. 

All safety mechanisms and guards must be refitted and reactivated as the work is 

completed. 

General and Safety Instructions | Operating Manual TOPAX DE |

1.9 Unauthorized modifications and production of spare parts 

The device may only be modified or converted in consultation with the manufacturer. Genuine 

spare parts and accessories authorized by the manufacturer ensure greater safety. 

The use of other parts can void the liability for the subsequent consequences. 

1.10 General notes of instruction! 

Measuring cables must not be laid parallel or close to power supply or high-voltage current 

lines. Interferences would mutilate the measurement. At close distances, power supply and 

measuring lines may only cross at a 90° angle. 

The admissible length of the measuring cables must be adhered to with regard to the sensor 

used. It is of decisive importance whether high-impedance (e.g. pH value) or low-impedance 

(e.g. free chlorine sensor) measurements are carried out. In the case high-impedance 

measurements, make sure that the (plug) connections are clean and dry (plug) and 

the lines do not become brittle due to sharp buckling. The screened cables normally used 

for such measuring lines must be handled according to the prescribed quality. Screening 

may only be connected to ground at one end of the cable (preferably at the controller). 

Interface lines must be twisted and screened (see recommended cables). 

IMPORTANT! 

IMPORTANT! 

If possible, a continuous cable from sensor to measuring input should be used. 

An extension of the cable by plugs or terminal socket increases the risk of disturbances 

due to contamination, humidity or excessive transition resistances. 

1.11 Scope of delivery 

IMPORTANT! 

Please unpack the dosing pump and ordered accessories with great care in order 

not to miss any small parts. Immediately compare the scope of delivery with 

the delivery note. The cause of any discrepancies must be determined. 

IMPORTANT! 

1.12 Disposal 

Should the device need to be permanently taken out of operation, please bear in mind that 

it contains electrolytic capacitors and must therefore be disposed of accordingly.

2. Device Installation and Connection 

Installation 

Schematic diagrams and dimensions are provided over the next few pages herein. 

A 92x92mm cut-out is required for the device casing. The device must then be pushed in 

from the fore end and fixed in with the appropriate lock-on clips provided on issue. 

The wall-mount casing can either be hung up to or foisted into the assembly slot, according 

to preference. It must then be fixed on with two screws. 

CAUTION 

The device assembly site must be selected so that the device is not subject to 

any mechanical load or chemical exposure in any way! 

Please note that the relative protection classes are: 

built in casing: IP54 for the front end, with IP55 at the front end door 

wall-mounted casing: IP65 (with closed clamp covers) 

CAUTION! 

Connections: 

Connection diagrams are provided over the next few pages herein. 

Please beware of the supply voltage specified on the rating plate at all times. 

CAUTION 

Input, output and control lead wires and cables must always be kept unattached 

from one another. In particular, they must be totally detached from power lines! 

All input and output wires and cables need to be shielded. The shielding can bear on one 

end only. 

For safe measurement data protection from any external disrupting influences, exclusive 

use of the specially shielded cable provided on issue to ensure effective measurements, is 

required. 

For Pt100 temperature sensor connection, use of a low-ohm cable with a large section is 

required. 

Upon relay connection, please beware that inductive loads need to be interference-suppressed. 

If this is not possible, the device terminal strip relay contacts need to be provided 

with an RC-protective circuit. With direct-current voltage, the relays or contactor coil need 

to be interference-suppressed via a free wheeling diode. 

CAUTION!

2.2 Installation of built-in casing 

Prepare a 92 x 92 mm 

cutout. 

Insert the device in from 

the fore end firmly, and 

fixed it on using the 

appropriate lock-on clips 

provided on issue. 

Use a screwdriver to adjust 

the lock-on clip screws 

until the device is firmly in 

place. 


2.3 Assembly of wall mounted devices 

First, remove the terminal 

covering. 

Prepare three drill holes 

(to be max. M5). Check 

the top hole, to ensure 

that the wall-mount casing 

can either be safely hung 

or foisted on. If it is hung 

on, the top hole must be 

120 mm above the bottom 

two. If it is foisted on, said 

distance must amount to 

135 mm. 

In both cases the screws 

must protrude for at least 

3mm. 

Hang the device onto the 

top screw or foist it on from 

the underside, then fix it on 

via the two bottom screws. 

Either fit the terminal covering 

back on, or proceed 

directly with the various 

connections.

Once switched on, the device will initially display the measuring value data. Controller 

unit displays will also display the operating mode (Auto/Manual) and th activation mode of 

relays S1 and S2. 

It is possible to scroll through the menu via the operating keys: 

Use key “” to go from the measuring value indication to the main menu. Use key “” 

and “” to scroll upwards and downwards. 

A black cursor bar will highlight the display row you are currently on. 

Use key “” to select a menu or a parameter. 

Use key “” to exit a menu and to save/enter data. 

The “ESC” key will exit a menu without saving any data. 

The “OK” key represents an additional safety function. Any device function or command 

that will then be extremely tedious to reverse, can only be activated by the simultaneous 

pressing of two keys. For example, for calibration entries, it is necessary to press both the 

“OK“ key and the “” key simultaneously. 

NOTE! 

The panel mounted device and the wall mounted device only differ from one 

another in that they have different external casings and a different number of 

outputs. Programming and operation functions are identical.

3.1 Parameter settings 

Selection of the various options 

In most cases, all that is required is selection of the various options provided. For example, 

when you need to select either manual or automatic temperature compensation, simply 

use the “” key to scroll across from one option to the next, until you come back to the 

start point or until you reach the option required. 

For these parameters, any changes are effective immediately upon selection. There is no 

need to enter an extra saving command for setting activation.

Numeric parameter settings 

Numeric parameters can be modified basically only if they are highlighted by a short cursor 

bar. To do so, use the “” key to access the parameter in question. 

Use keys “” and “” to enter the required number. Briefly pressing down on the key 

once will also increase or decrease the last position by 1. If the key is pressed and held 

down for longer, the number starts running in fast forward or backward mode until the key 

is released. 

Press the “” key to enter and save the setting. The cursor bar will extend itself over the 

entire line setting field.

Two-key operations 

The “Calibration” and “Delete Memory” functions that are extremely tedious to reverse, can 

only be activated by the simultaneous pressing of two keys. 

It is thus necessary to press the “OK“ key and, whilst keeping it pressed in, to also press 

the “” key simultaneously. Subsequent to calibration you will see that the metering value 

is the same as that of the compared value, and subsequent to delete memory the device 

will go back to the measured value display.

Code 86 enables access to all parameters and functions 

All the other codes will not enable access to any parameter and function. 

When finished entering all the required settings has been accomplished, it is necessary 

to “close” the device back down. It is thus possible to enter 11 again or any other number

5. Metering Unit Settings 

Free chlorine and chlorine dioxide measuring 

The measurements of free chlorine and chlorine dioxide are defined by the example of the 

measurement of free chlorine. 

Chlorine measuring is dependant on the pH value and the flow rate. The flow rate is kept 

constant via the valve whereas the pH value can be compensated. Once a compensation 

process has been activated, it is necessary to re-calibrate. We therefore recommend to 

first calibrate the pH metering and to set the test water at the target pH value, before 

calibrating the chlorine metering and operating the chlorine controller. 

Chlorine measuring requires a calibration through which the current electrode features and 

data need to be detected and acknowledged. 

This occurs through identification of the current chlorine concentration by means of a 

compared measurement, e.g. with a photometric DPD method, for subsequent comparison 

with the current measured value. During calibration the electrode is left in the valve thus 

the flow rate must not be altered during the calibration process. 

One attaches - only during the chlorine measurement – an amperometric measuring cell 

instead of a potentiostatic one, and carry out a two-point-calibration when it is started up 

and equilibrate the zero-point. 

The measuring cell has to operate with chlorine free water for the zero-point calibration 

or the flow rate of the measuring water has to be suppressed. If the value on the display 

does not alter anymore, then “0.00 mg/l” has to be entered into the menu and saved. A 

zero point calibration is not necessary for chlorine metering although it is possible to run if 

effectively required. 

After calibrating the zero-point the amperometric measuring cell has to be driven with 

chlorine water. If the value on the display does not alter anymore, the chlorine content in 

the measuring water is determined using the DPD-method. After determining the value 

it has to be entered into the control system and saved. The measuring water has to be 

taken from the measuring cell. 

pH measuring 

pH metering too requires calibration, which is conducted by measuring two calibration 

solutions having pH values that are known. The pH values of both calibration solutions are 

entered into the calibration data. 

If calibration with special buffer solutions is required, the device calibration data must 

first be changed. In this case it is also necessary to consider the internal electrode buffer, 

should it differ from pH7. 

Compensation of the temperature influence can either be conducted manually or automatically. 

Manual compensation requires for manual temperature setting whereas automatic 

compensation requires connection of a PT100 temperature sensor. 

Redox measuring 

ORP metering is not subject to calibration and neither is temperature compensating 

required.

Temperature measurement calibration 

Because the temperature sensor is hooked up implementing dual-lead technology it may 

be possible to have slight variations in temperature measurements. The temperature 

measurement can thus be calibrated. 

Measure the temperature once manually whilst putting the device into operation and 

set the correction value under “Correction to Pt100” in such a way that the temperature 

display corresponds with the manual temperature measurement read offs. 

5.4 pH compensation (Cl 2 

measuring only) 

Under the “Compensation” menu it is additionally possible to turn the pH compensation on 

and off. Bear in mind that subsequent to switch-on, you will need to calibrate the chlorine 

measurement compensation all over again.

6. Controller Unit Settings 

The controller settings of free chlorine, chlorine dioxide and pH are defined by the example 

of the controller of free chlorine. 

The TOPAX DE comes equipped with one chlorine value and one pH value controller (DE 

2 only). Both controllers can be configured maximally as PID controllers and are provided 

with a maximum of 2 dual switch points, thereby also allowing for adjustable operation 

mode. 

The actuating variables can be output through three relays and through each one of the 

three outputs. 

The device will assist you during configuration. Firstly, on the one side the device is already 

delivered from our works with typical pre-configured settings so that as little adjustments 

as possible are required. If any adjustments are needed, each selection that you come 

across will only display the settings required for the selection in question: meaning that 

the initial abundance of setting options is quickly cut down to a quick-overview selection 

and it is possible to determine straight away when a chosen selection will not provide the 

required results. 

NOTE! 

Only switch points that are assigned to a relay or to an output are displayed 

under the “Set Point” menu. If no relays or outputs are assigned to a controller, 

when the “Set Point” menu is selected, the device will display the “Function currently 

not active” message! 

NOTE! 

When a relay is configured as an alarm relay, a good number of threshold values 

may be assigned to it. However, relays that are assigned to one switch point 

cannot avail of any other application or switch point. 

For controller implementation, a set of four controller options are provided: 

NOTE! 

NOTE! 

ON/OFF Controller 

The ON/OFF controller switches ON when a switch-point threshold is exceeded and goes 

OFF when a threshold is under-run, or vice verse, based on effective operation direction. 

Metering is therefore always carried out at 100% (ON) or 0% (OFF). A hysteresis can be 

preset for standard system parameters. 

P Controller 

The P Controller or Proportional Controller provides for metering reduction upon approaching 

of the set point, proportionally to control deviation. This occurs constantly on application 

of the output as standard output, on application of the relay either via reduction of 

the switching frequency (Impulse Frequency Controller) or via reduction of the time slice of 

a preset switch frame, with the relay OPEN (Pulse Pause Controller). Setting of the P gain 

range is required and so is setting of the impulse frequency, of the pulse + pause time as 

well as minimum impulse data, subsequent to every parameter application. 

Controller Unit Settings | Operating Manual TOPAX DE | 29

PI Controller 

The PI Controller or Proportional Integral Controller is the P Controller with an additional 

Integral function. The settings are carried out as per the P Controller, whereby additional 

setting of a so called reset time, corresponding to the “I” integral gain, is also required. 

The “I” gain locks on later compared to the P Controller and principally eliminates residual 

control deviation, constant to the P Controller. 

PID Controller 

The PID Controller or Proportional Integral Derivative Controller is the PI Controller with an 

additional Derivative function. Further to the specified settings, derivative time, corresponding 

to the “D” gain, is further provided here. The “D” gain locks on earlier to balance out 

inertia by the “I” controller. The adjustment control is therefore provided with a quicker 

reaction to any control deviation. 

PI and PID controllers provide the additional possibility of servo motor control. Only one effective 

direction is however possible, as both switch points are implemented for one motor. 

6.1 Configuration on Delivery 

When delivered from our works, device configuration is as follows: 

Controller Controlled process variable Effective direction Relay 

Cl 2 

controller Cl 2 

Free chlorine measurement value boosting 1 

pH controller pH measurement value dropping 2 

NOTE! 

NOTE! 

The pH value can be controlled only with TOPAX DE 2. 

Both P controllers are preset as pulse-pause controllers with a 10 sec pulse-pause time, 

and a 0.5 sec minimum impulse. 

The third relay is configured prior to delivery as an alarm relay for threshold value monitoring 

of both the chlorine measurements as well as the pH measurements. 

During factory settings, the outputs are not implemented for control. 

Should you need to change any of the preset settings, it is necessary to access the 

“Controller” menus under the device default settings. A description of the process steps is 

given over the next few pages. 

Set points and proportional ranges are also pre-configured in our works, although readjustment 

thereof is possible at all times without altering configuration by accessing the “Set 

point” menu under the main menu. 

6.2 Configuration changes 

Access the “Controller” menu in the default settings. 

Select the controller that needs to be set. This will also access the configuration window.

6.4 Switching the controller unit ON and OFF 

To switch the controller unit ON and OFF, access the main measuring value display page 

and press key “” directly. By so doing, you will switch from manual operations (controller 

OFF) to automatic operations (controller ON) and vice verse. The current operating mode is 

shown on display. 

NOTE! 

WARNING! 

Check to ensure that the controller has been switched off prior to connecting up 

metering pumps or any similar devices to the unit! 

6.5 Switch–on delay 

By means of the switch-on delay function, it is possible to enter a time setting that must 

go by every time the device starts up, re-starts or the power is cut off, before the control 

functions all become active. This delay time gives the measuring processes time to settle 

and stabilise, thereby preventing false metering incidents in the device start-up phases. 

WARNING! 

6.6 External Controller stop 

It is also possible to switch the device ON and OFF externally. No settings are required 

to do so. All that is required is an external potential free dry contact connected up to the 

digital input. When the input is open, the controller stops and the “External Controller Stop” 

message will come up on display.

It is possible to set alarm values for all the threshold values that have a relay allocated to 

them. 

If one of the values is exceeded the display will show the “Threshold values exceeded” 

message and will cut off the relativ relay, which in turn can act on an external sound 

warning such as a horn, or on a warning lamp. 

Alarm delay 

Depending on the type of control processes being run, threshold values can also be exceeded 

during standard operations. To prevent that during any such brief value overshoots an 

Alarm is given off, it is possible to set a threshold value excess delay time that must first 

go by before the alarm is set off. 

In other words, the alarm will go off only if the threshold value is either exceeded or falls 

short for a time that is longer than the delay time setting. 

NOTE! 

Threshold value monitoring is only active if the Controller is switched on, with 

the display showing it is in AUTO mode. If the controller is switched to MANUAL, 

the alarm alert is cancelled and the relay will switch OFF.

6.9 Metering Control 

During controller settings it is possible – separately for each controller – to enter a time 

setting determining the maximum length of time allowed for metering operations at full 

capacity. 

If, after the above set time the set point or the set P gain values have not yet been reached 

and the activating variable is still only about 100%, the alarm goes off and the relay is 

switched off.. 

This is to avoid, for example, that uncontrolled, dangerous substances are set free in the 

event that a metering hose is damaged. 

NOTE! 

If the metering control is up to standard, only the controller in question is deactivated.

7. Alarm 

Alongside the metering control function, the device is also provided with a set of further 

alarm functions. 

In the event that an Alarm does go off, the relay that is configured accordingly is cut off 

instantaneously and a text message is displayed, specifying the reason for the alarm. 

If an alarm event will not allow for control processes, as soon as the alarm is tripped off 

the controller is deactivated. It is only enabled when the device turns off the alarm, which 

occurs automatically provided that the reason causing the alarm is removed. 

Sensor-Check Calibration 

If a sensor does not produce satisfactory data upon calibration, an error message is 

displayed, until a new calibration process produces satisfactory data. In this case the 

controller is not blocked – in order not to stop the system, the controller can continue 

operations either with a replacement sensor, or a cleaned or regenerated sensor, until 

replacement is available. 

Sensor monitoring during measurement 

Also during the regular continuous measuring mode, all connected sensors are monitored. 

If a measuring process receives a meaningless signal, e.g. upon cable failure, the alarm is 

tripped off and the relative controller unit is deactivated. Both the alarm and the controller 

stop mode remain active until meaningful signals for the measuring process in question 

are not resumed. 


If a water deficiency sensor is hooked up to the digital input, an alarm is tripped off as 

soon as the gauge switches. The alarm is reset as soon as water is available again. The 

controller is stopped for the overall duration of this alarm condition. 

Metering monitoring 

If a controller goes on metering at 100% for longer than the appropriate time set accordingly 

in the controller settings, an alarm is tripped off and the controller in question is 

deactivated for the overall duration of the alarm condition. 

WARNING! 

The metering monitoring permanence only responds to 100% metering. If for 

example you have a chlorine control set point amounting to 0.3 mg/l and a set 

P gain amounting to 0.5 mg/l, the required 100% is not reached, even if for 

example it may occur that there is no longer any chlorine content in the water 

due to metering hose failure or damage! Therefore, kindly check prior to starting 

up the controller whether your settings will allow/are suitable to a metering

Input 1 (Cl 2 

) error 

Input 2 (pH) error 

Input 3 (ORP) error 

Input 4 (T) error 

The rise slope recorded on 

calibration was less than 

3mV or more than 100mV 

for chlorine and less than 

50mV/pH or more than 

65mV/pH for pH (at 25°C) 

The zero point error recorded 

on calibration was 

larger than +/- 59mV. 

The input on display is not 

receiving any signals. 

Check the temperature, the flow rate, the 

pH value and the connection and calibrate 

them all over again. If the rise slope error 

still persists, the electrodes either need to 

be regenerated, cleaned or replaced. 

Check to see whether the internal buffer 

setting coincides with that indicated on the 

electrode, then calibrate again. 

If the zero point error still persists, try 

regenerating the electrodes (replacement of 

the KCl solution in the liquid filled reference 

electrodes and/or storage of the electrodes 

in a 3-molar KCI solution) 

This error message indicates that there is 

a component failure. Apart from the sensor, 

it could also involve a cable or a defected 

connection. 

Input 4 (T) error could also come on display, 

when automatic temperature compensation 

is selected although no dedicated temperature 

sensor is connected.

8.3 Assembly of a Data Network (TopView) 

With the (optional) RS 485 computer interface it is possible to transfer data to a PC. Furthermore 

multiple TOPAX DEs can be connected to a network. Each TOPAX DE (with RS 

485) has to be allocated an address for this purpose. 

CAUTION! 

The network address 10 is not permitted. 

The maximum length of data transfer amounts to 1000 m. Up to 14 TOPAX DEs can be 

connected with a PC to a network. The data line has to be attached directly to the TOPAX 

DE’s RS 485 terminal: 

CAUTION! 

Casing Connection Allocation 

wall assembly terminal 18 + A 

17 - B 

mounting sub-D 3 + A 

8 - B 

CAUTION! 

Separate connection sockets or junction boxes within the data line have to be 

avoided. One must use a cable type “KAT.5, 2X2XAWG24/1 (Lapp cable) or better. 

The manufacturer is not liable for this. 

Due to electromagnetic compatibility the cable’s screen has to be connected on both sides 

before the device connections large surface area and conduct well with the protective 

earth. For this it has to be confirmed that no potential current loss can escape over the 

screen. 

Today’s computers are equipped with a serial computer interface RS 232 (9-pin Sub-D 

connector) and/or with a USB-connector. In this case an additional connector converter 

has to be inserted in the PC (RS 485 to RS 232 or RS 485 to USB). 

CAUTION! 

120 ohm cut-off resistances 

At both ends of the network the data line has to be cut off with a resistance of 120ohm. 

It is possible to put the switch for the resistance on the last TOPAX DE in the network 

through the composition of jumpers (see following illustration). 

If the connector converters with order no. 44300101 (RS 232 to RS 485) or no. 44300102 

(USB to RS 485) are attached to the PC, the cut-off resistance of the PC’s sides is already 

activated. 

Pull-up/pull-down resistance 

The data line has to be set at a fixed potential. For this purpose plug-in jumpers have to 

be inserted into the last TOPAX DE (Pull-up/pull-down resistance). A cut-off of the cable 

with Pull-up/Pull-down resistances is fundamentally necessary for the RS485-connections, 

in the times, in which the data sender is active, in order to exact the quiescent level on the 

bus system. Without this measure it is not possible to transfer data. 

Data readout | Operating Manual TOPAX DE | 41

To activate all resistances jumpers have to be attached to the TOPAX DE (see following 

illustration). For this purpose the device front has to be unscrewed and flipped up. 

CAUTION! 

WARNING! 

CAUTION! 

You must only insert the 120 ohm Pull-up/Pull-down resistances into one TOPAX 

DE, the last one in the network. (No resistances are inserted in its delivered 

state). 

WARNING! 

Before opening switch the device without fail to zero-potential!!

CAUTION! 

With a defect in the TOPAX DE, in which the Pull-up/Pull-down resistances are 

installed, the total network does not function and the transfer of data is no 

longer guaranteed. In this case the resistances have to be installed in another 

TOPAX DE. 

CAUTION! 

TopView 

To visualize the data read out in the network we offer the application TopView 2.0 in two 

versions: Standard and Mini. The programme “TopView 2.0 Standard” has the order no. 

78349. The Software “TopView 2.0 Mini” is free to download from the manufacturer’s 

website.

9. Operation and Maintenance 

Device Maintenance: 

Device operation is maintenance free. No check settings are required during operation. 

Should you however require a verification of your device at any time, you can forward it 

to us. It shall be returned to you within two weeks together with a protocol test report. 

Alternatively, one of our Service Technicians can carry out the examination directly at your 

works. 

Safety protection replacement 

Wall mounted devices are equipped with an internal safety protection that in case of 

necessity, may have to be replaced. A spare safety protection is accordingly provided on 

issue with the device. You will find it is stored in the terminal covering. Data concerning the 

safety protection is provided under the “Technical Specification” section herein. 

For safety protection replacement, it is necessary to unscrew and remove the front end of 

the device by flipping it upwards. The safety protection is located about half way up on the 

right edge of the board. It is locked on with a bayonet catch. Rotate the catch leftwards, 

until the safety protection slips out. Exchange it with the spare safety protection and fasten 

it in place by turning the catch rightwards. Replace the front end of the device back on 

again and screw it on accurately and firmly. 

WARNING! 

Prior to opening it, make sure that the device is totally powered down. 

WARNING! 

CAUTION! 

CAUTION! 

During these service and maintenance operations, beware with the connection 

cable located along the front end of the device! 

Cleaning 

Please ensure that during cleaning operations, the face end of the device does not come 

into contact with solvents such as methanol, alcohol or methylated spirits. Take care that 

no water permeates into the device. We recommend cleaning the device by simply wiping 

it with a clean, damp cloth. 

Measurement maintenance 

It is necessary to clean off the sediment deposits and fatty substances from the electrode 

metal surfaces at regular intervals. The pH electrodes and the reference electrodes are 

subject to deterioration over time, so that the relative features also change over time. Said 

variations must therefore be ascertained and checked regularly. 

NOTE! 

NOTE! 

At every calibration process, the device tests the applicability of the sensors and 

specifies when a sensor needs to be changed. In this connection, please refer to 

the “Alarm Message” section herein.
