PROPRIETARY NOTICE 

The information contained in this publication 

is derived in part from proprietary and patent 

data. This information has been prepared for 

the express purpose of assisting operating and 

maintenance personnel in the efficient use of the 

instrument described herein. Publication of this 

information does not convey any rights to use or

WARNING 

This instrument contains electronic components 

that are susceptible to damage by static 

electricity. Proper handling procedures must 

be observed during the removal, installation, or 

handling of internal circuit boards or devices: 

Handling Procedure: 

1. Power to unit must be removed prior to 

commencement of any work. 

2. Personnel must be grounded, via wrist strap 

or other safe, suitable means, before any 

printed circuit board or other internal devices 

are installed, removed or adjusted. 

3. Printed circuit boards must be transported 

in a conductive bag or other conductive 

container. Boards must not be removed from 

protective container until the immediate time 

of installation. Removed boards must be 

placed immediately in a protective container 

for transport, storage, or return to factory. 

Comments: 

This instrument is not unique in its content 

of ESD (electrostatic discharge) sensitive 

components. Most modern electronic designs 

contain components that ut ilize metal oxide 

technology (NMOS, CMOS, etc.). Experience 

has proven that even small amounts of static 

electricity can damage or destroy these 

devices. Damaged components, even though 

they appear to function properly, exhibit early 

failure.

GENERAL DESCRIPTION 

FEATURES 

Principle of Operation 

Beam blockage 

A beam of microwave energy passes from 

a sender to a separate receiver in bursts 

approximately 200 times per second. If the 

path between the sender and receiver is 

blocked by any object or material which absorbs 

or reflects microwave energy, then the 

receiver will not be able to detect the signal. 

The presence or absence of the signal at 

the receiver is used to switch a relay for 

indication or control purposes. 

Microwaves are small (Micro) radio waves 

transmitted from point to point hence the 

system setup of ‘sender’ and ‘receiver’ units. 

Note: 

For wet, dusty environments where 

build up issues of wet high dielectric 

material is prevalent Microwave 

technology will have performance 

problems. Hawk recommends the 

Gladiator Acoustic Switch for these 

applications. 

• Wide beam pattern for easy alignment 

• LCD setup/diagnostics on remote amplifier 

• Ranges up to 200 meters (656 ft) 

• Simple ‘1-minute’ setup 

• Remote sensor or Smart Integral ‘all in 

one’ types 

• Relay outputs: Smart Integral (1) Remote (2) 

• Remote test function 

• Adjustable ON and OFF delays (0-20 sec) 

• Smart communication options: GosHawk, 

Modbus, HART, Profibus DP, DeviceNet

Rev 1.71, Sept 2013 

MOUNTING 

GENERAL GUIDELINES 

1. The microwave beam is a polarized form 

of energy. As such, it is necessary to align 

the units in the same spatial plane. If the 

units do not have the same orientation, the 

amount of received energy is diminished. At 

90° to each other, the detector is blind and 

cannot detect the beam. The actual angle 

of mounting is not relevant, so long as both 

the Sender & Receiver have the same angle 

and elevation. Flanges are marked with an 

alignment notch cut into one edge of the 

flange to assist in mounting correctly. 

2. When looking for a mounting location it 

is important to locate and mount the interior 

of the window/sensor face for each unit 

flush with the vessel wall and where minimal 

build-up will occur. The system can penetrate 

through generous amounts of buildup 

of various products, however, the better the 

position, the more reliably it will operate. A 

cavity in the vessel mount position where 

build up is possible will result in a ‘plug’ 

forming in front of the beam path resulting in 

unit performance issues. 

3. Microwave energy cannot penetrate 

through steel linings or other conductive 

linings. You must cut a viewing hole and use 

an appropriate windowed weldment. 

4. For high vibration applications, it is 

necessary to isolate the electronics to keep 

them from long term damage. This is most 

often accomplished using 4” UHMW or 

Teflon windowed weldments in the vessel 

walls, and mounting the Microwave Sender 

and Receiver to a separate stable structure 

(I-beam, handrail) to isolate them from vibration. 

Isolation shock mounts can also be 

provided to help protect the electronics. 

5. For high temperature applications which 

exceed 65°C/150°F (precipitators, cement 

cyclones, etc.), it is necessary to ensure 

that the sensors always remain below 

65°C/150°F. This is normally achieved by 

installation of temperature resistant windows 

of ceramic or firebrick, and positioning 

of the Sender and Receiver in line with the 

windows, and set back far enough that their 

temperature remains below the given limit. 

Where this is impossible, it will be necessary 

to use remote mounting microwaves 

with waveguide assemblies. This allows 

the electronics to be placed in an area 

where ambient temperatures do not exceed 

the maximum allowable for operation. It is 

necessary to contact the factory for this last 

type of waveguide application. 

13



Rev 1.71, Sept 2013 

MOUNTING 

SPECIFIC APPLICATIONS 

1. When mounting to monitor the level 

of a flowing product such as coal, ore or 

wood chips, position the microwave path 

out of the direct product flow stream. If at all 

possible, go behind the flow stream or well 

in front of it. This will minimise any possibility 

of unwanted trips due to abnormal 

product flow blocking the beam. Always use 

the recommended setup for blocked chute 

detection. 

2. When using the system as a proximity 

switch such as truck detection the mounting 

arrangement is application dependent 

and must ensure proper operation even 

under worst case conditions. 

4. Mounting of a Microwave system on 

sloped vessel walls can be accomplished 

using the Microwave Adjustable Mount (MA- 

12 or MA-13). This system allows the microwaves 

to be mounted to a sloped surface 

and then adjusted horizontally for optimum 

performance and operation. The adjustable 

mount has an integral 4” weldment with 

UHMW polyethylene or PTFE (Teflon) window 

options. An option with the bracket is a 

vibration isolation kit (shock mounts) to help 

protect the electronics from damage. Each 

side wall of the vessel must not exceed 30 

degrees from the vertical centerline. To 

mount the adjustable bracket, simply cut a 

hole and weld the 4” weldment directly to 

the vessel, install the window, mount the 

microwave and adjust horizontally. 

Similar performance can be obtained by 

fabrication of fixed brackets which mount 

the Sender and Receiver in direct line with 

one another and aimed through the centre 

of two MA-4 windowed weldments. 

6. For boom protection / anti collision 

mounting the MA15 flange pipe should be 

used to assist in the reduction of beam 

spread over long distances. The units 

should be mounted with a 2 meter exclusion 

zone in mind for the beam path between 

the sender and receiver. Do not use Integral 

units for boom protection. 

See the dedicated Hawk Microwave alignment 

& setup procedure guide for further 

information about anti collision / boom 

protection application information

TEST TERMINAL FUNCTION SELECTION 

The test terminal has two potential modes of operation for Smart Integral units and always 

operates in the test input mode for Remote units. Remote units have a separate, failsafe 

relay contact, which is always functional. 

TEST INPUT MODE 

(Test switch must be in ‘TEST’ (ON) position on Smart Integral Units - function always enabled on Remote Units) 

Test terminal acts as an input for remote testing of the instrument’s switching function. Used 

to check for malfunction of unit from a remote position, PLC, SCADA etc. For more information 

see page 29.

Test terminal will provide an output which is able to switch an external failsafe relay or PLC/SCADA/DCS 

input. During normal system operation this terminal will internally switch a solid state (transistor) output to 

ground (or DC ‘-’). If power fails or an internal system failure occurs, the terminal will act as an open circuit.

The pulse rate may be changed to minimize 

the potential for cross-talk if multiple units are 

in the same operational area. If cross-talk is 

likely to occur, it is strongly recommended 

to use Remote type units and employ the 

cross-talk prevention schemes for 2 units or 

the multi sequence connection for more than 

2 units using a separate GMSEQ sequencing 

unit. Cross-talk prevention and sequencing for 

Remote units are detailed on pages 20 & 21.

SMART INTEGRAL VERSION 

! 

1. Mount the units in their actual position 

1.1 If units are AC powered ensure proper grounding is 

connnected to ground screw. 

2. Make sure that the material or target is not blocking 

the path between sender and receiver. 

3. Turn the power on 

The green LED on the sender and receiver will stay 

on permanently to indicate that power is on. Green 

LED on receiver varies in brightness with strength of 

received signal. 

4. Sender (GMRS): Ensure the REM/INT DIP switch 

is selected to the INT position and the remaining 

switches (1, 2, 3) are all selected to OFF. 

5. Select the required relay action 

The Relay can switch ‘ON’ (FSL) or ‘OFF’ (FSH) as 

the microwave beam is blocked. Set the relay action 

selection switch position depending on your requirements. 

FSH is recommended (ordinarily on/energised, 

switches off/DEN during blocked conditions). 

6. Select the sensitivity 

There are two adjustments controlling the sensitivity of 

the switch point: 

6.1 The ‘HI/LO’ sensitivity DIP switch is used as 

the primary sensitivity setting. Select LO sensitivity 

for Blocked Chute detection. Select LO If build-up 

is expected over sensors or with strongly absorptive 

materials or targets. Select HI sensitivity for clean 

environments and lighter/less absorptive material or 

targets. LO recommended for most applications. 

Recommended Settings for 

Blocked Chute applications 

6.2 The sensitivity potentiometer 

Turning the pot fully counter-clockwise factory recommended 

for blocked chute applications. If operating 

in HI mode set the pot to 12 o’clock. In this mode you 

can turning the pot clockwise to reduce the amount of 

beam blockage required for switching and vice versa. 

7. Select the time delay 

Full anti clockwise is minimum (0.1 seconds). Full 

clockwise is maximum (20 seconds). Adjust as 

required allowing time to avoid possible nuisance trips. 

The selected delay will be used for both an ON delay 

and an OFF delay. 

8. Perform a CAL mount 

Do not proceed with this step unless the material or 

target position is well beneth the line between the 

sender and receiver. 

Switch the Mounting Calibration switch on the Receiver 

unit to ‘CAL’ (ON) position. The Blue LED will blink to 

indicate that mounting calibration is now in progress. 

Wait 5-10 sec, then switch the mounting calibration 

switch to ‘OFF’ position. The blue LED will switch off 

after successfull calibration. If it stays on this indicates 

there was a calibration error. If this is the case please 

check that the path between sender and receiver is 

clear and alignment is correct then try the calibration 

again. If mounting calibration was successful the blue 

LED should be off and the Green LED should be ON. 

9. Switch check 

If required block the Sender with a steel plate to check 

relay action & time delay. The green LED will dim when 

the Microwave beam begins to be blocked. 

You can also press the ‘TEST’ button on the Sender to 

simulate a blocked chute condition and thus trigger the 

relay action. 

Note: Integral type Microwave systems should not 

be used for anti collision detection / boom protection. 

Contact Hawk for information about the remote type 

systems.

1. Mount the unit in its actual position 

(see mounting procedure - pages 12-16) 

Make sure that external ground wire is connected 

between the outside ground screw on the Gladiator 

housing and the roof/wall/side of the silo/tank/vessel/chute. 

(For non metallic tanks make sure that 

external ground wire is connected between the 

same outside ground screw on the housing and the 

general plant ground potential.) 

2. Check where the actual level or target is relative 

to the sensors 

Make sure that the material or target is not blocking 

the path between sender and receiver.

3. Ensure that the mode selection switch on the 

transmitter is set to REM (OFF). See point 1 page 31. 

4. Turn the power on 

The display will turn on and the fail-safe relay will 

switch. The display will scroll through the following 

messages: Hawk, Amp SerialNo, Type, Amp Soft 

Ver, Device ID, SensorSerial, SensorModel, Sens 

SoftVer, Sensor Addrs, Gladiator System Amp. 

The unit will then go into operational mode displaying 

‘Switch’ with a % value. This % value represents 

the changing amount of signal loss between 

sender and receiver. 

5. Simple “1-minute” Setup - Follow the flow 

chart 

Choose Application Type 

Alignment - For Aligning the unit at long range. Unit is set to 1.2V signal (~48% switch 

value), move the unit face to get the volt reading high (2.4V will be the maximum 

reading or 0% switch value). Calibrate & re-select this mode and repeat till you cannot 

improve the alignment. 

Blocked Chute - Configures the unit for blocked chute applications 

Boom Protection - Configures the unit for anti collision applications 

Switch - Allows selection of Sensitivity% for standard switch application. 

Density - Special Density measurement mode. See App Types for further information 

Cancel Influence of Mounting 

Do not proceed with this step unless the material or target position is well beneth 

the line between the sender and receiver. 

Select ‘Yes’ to start the mounting calibration. ‘Wait’ will be displayed during the 

calibration for up to 30 seconds. Unit is now able to cancel the influence of the 

mounting. The % reading on the back lit display has been zeroed with the existing 

process conditions and the measurement history log has been cleared. 

Always calibrate the unit after changing Application type. 

Select the Switch point 

The output relay will switch at the entered % value. The default value of 76% will be 

suitable for detecting most media. For detection of products which are less absorbent of 

Microwave energy, select a lower % value and vice versa. For highly absorbent materials, 

almost any setting will work, but higher % settings will be more immune to build up. 

When the level or target falls below the sensors the relay will switch back at half of the 

entered switch point % value (when the beam is no longer broken). 

Select the Time Delay 

Set the time to be used for both switch on and switch off delays 

Select the required relay action 

The Relay can switch ‘ON’ or ‘OFF’ as the microwave beam is blocked and switch 

‘ON’ or ‘OFF’ in response to an instrument failure (see below). Set the parameter 

to FailSafe Low or FailSafe Hi depending on your requirements.

Sets the unit for blocked chute mode. Note 

that this mode may be unsuitable for very low 

dieletric materials. 

A special mode for aligning units over long 

range. After performing a Cal Mount and 

running the unit it will indicate half signal / 

approximately 50%. Improving the alignment 

will reduce the %. Re-calibrate if the % 

reaches 0. After using this mode you must 

select a normal app type.

Rev 1.71, Sept 2013 

RELAY 2 ACTIONS 

Concept 

The Gladiator Amplifier has received a 

firmware update to utilise the Relay 2 as 

a trigger mechanism to notify the user or 

activate a cleaning system based on time 

or conditions within the application which 

require cleaning. 

There are three software options using 

two diffferent concepts. The first concept is 

based on total Gain used and the second is 

based on a Time interval. 

The options are located in the Advanced 

menu as a sub menu for Relay2Action. 

The selectable software options are as 

follows: 

[Maintnce Chk] - The unit will switch on the 

relay when total Gain is greater than the 

CleanGainHigh % - the relay will switch off 

when Gain falls below CleanGainLow %. 

[GainOpt Clng] - When total Gain exceeds 

the CleanGainHigh point the unit activates 

the relay for 1/2 of the On Delay time and 

then switches off. The unit will then count 

the Clean Time interval time before repeat 

the process until total Gain is below Clean- 

GainLow point. 

Setup Example - Time Based 

In ‘Quickset’ Set ‘On Delay’ to 4.0 seconds - 

this will provide a 2.0 second water blast. 

In ‘Advanced’ set ‘Relay2Action to ‘TimeOpt- 

Cln’ with a ‘Clean Timer’ of 30min. 

Every 30 minutes the sensors will be 

sprayed for 2 seconds. 

Setup Example - Gain Based 

In ‘Quickset’ Set ‘On Delay’ to 4.0 seconds - 

this will provide a 2.0 second water blast. 

In ‘Advanced’ set ‘Relay2Action to ‘GainOpt- 

Cln’ with a ‘CleanGainHi’ of 80%, ‘Clean- 

GainLo’ of 70% and ‘Clean Timer’ to 5.0min 

This will trigger the water spray for 2 

seconds when Gain goes above 80%. The 

spray will repeat every 5 minutes until Gain 

goes below 70%. You can view Gain while 

the unit is running by using the arrow key to 

locate the diagnostic display 

[TimeOpt Clng] - At every Clean Time interval 

the unit will switch on the relay for 1/2 of 

the On Delay time and then switch off.

Rev 1.71, Sept 2013 

TROUBLESHOOTING 

Error 01: Amplifier/Transmitter can not 

communicate with sender/receiver. 

Error No 01 is displayed on power up with 

a reset loop or after unit has successfully 

operated and subsequently failed. 

Check wiring terminals for a loose or 

incorrect connection (including junction 

box/cable extensions). Check the cables for 

any signs of damage. Ensure any customer 

supplied cable meets Hawk specifications. 

Ensure correct power is applied to the 

correct terminals. DC only version units will 

not support AC. 

Use a multimeter to check voltage supply for 

the Remote Sender & Receiver on the red/ 

black labeled terminals of the Amplifier. You 

should get approximately as below: 

Sender 

+/- 24.0V 

Receiver: 

+/- 9.4V 

Ensure the Sender is set to the correct 

mode (integral or remote). This is set by the 

INT / REM switch on the Sender facia. 

Error 02: Communication data corruption 

between Transmitter and Transducer. 

It can be a result of noise in data lines or 

one of data lines (white or blue wires) being 

open circuit. 

1. Make sure wiring is correct especially 

look to the screen (earth). 

Error 03: Incorrect comms module selected 

(eg Profitbus, FF) 

Error 04: Amplifier is programmed with 

incorrect software. Contact your local 

support. 

Relays & LCD intermittently dimming 

and dropping out. 

Check incoming voltage with a multimeter. If 

unstable and dropping below 8V the unit is 

not getting enough power. 

If AC powered put a multimeter over the 

DC +/- terminals. The unit generates a DC 

voltage in these terminals if powered by AC. 

This should read at least 8V consistently. If 

this is unstable and dropping below 7V while 

your incoming AC is stable there is likely 

a problem with the internal power supply. 

Contact your local distributor or Hawk. 

Note: 

For wet, dusty environments where 

build up issues of wet high dielectric 

material is prevalent Microwave 

technology will have performance 

problems. Hawk recommends the 

Gladiator Acoustic Switch for these 

applications.
