DESCRIPTION OF FILTER OPERATION
Filtering process:
The SAF-6000 is a sophisticated yet easy-to-operate automatic filter, with a self -cleaning mechanism driven by an electric motor.
The SAF-6000 is designed to work with various types of screens in filtration degrees from 500 to 10 micron, and is available in 6",8"
and 10" inlet/outlet diameter.
The water enters through the inlet pipe into the coarse screen from outside in, and through the fine screen from inside out. The
"filtration cake" accumulates on the fine screen surface and causes head loss to develop.
The coarse screen is designed to protect the cleaning mechanism from large dirt particles. It should not accumulate large quantities
of suspended solids and is not cleaned automatically.
Self-cleaning process:
The SAF-6000 will start the self -cleaning process when the pressure differential across the screen reaches a pre-set value or a
predetermined lapse of time.
Cleaning of the filter element is carried out by the suction scanner which rotates in a spiral movement while removing the filtration
cake from the screen and expels it out through the exhaust valve.
The rotation of the scanner is operated by a 2-way (fwd/rev) drive unit that is attached to the scanner by a threaded shaft which
provides the linear movement.
The exhaust valve is activated for the duration of the cleaning cycle by a 3-way solenoid. During the self-cleaning process, which
takes approximately 35 seconds, filtered water continues to flow downstream.
Different modes of filtration:
The filtration system may be found in one of the following modes:
1. Filtering mode: This is the normal function condition. Flushing is not occurring and the power light on the control board is lit.
2. Flushing mode: A mode in which the flushing process is in progress. The motor and exhaust valve are operating according to
the program.
3. Continuous flushing mode: It is possible to activate the self-cleaning mechanism continuously by changing the switch near the
timer in the control board to "CONT." position.
4. Malfunction mode: During malfunction mode the self-cleaning operation is stopped, the malfunction light on the control board is
turned on and an external output is activated with 24V AC.
6
amiad filtration systems

The filtration system may enter a malfunction mode in the following cases:
1. When there is a continuous signal from the pressure differential switch for a duration of more than the pre-set time. This means
that the self-cleaning process is not successful.
2. When the motor protector was activated, either manually or due to over load.
3. A malfunction in the limit switches.
Initiation of self-cleaning:
The filter will enter the self-cleaning process as a result of any of the following causes:
1. A signal from the Pressure Differential Switch (PDS) - The PDS which is situated on the filter body, sends an electric signal
when the pressure differential across the screen reaches the pre-set value (usually 0.5 bar =7 psi). The control board registers
the signal and operates the flushing process according to its program.
2. Manually pressing the "TEST" push button at the control board.
3. The TIMER installed in the control board allows operation of self-cleaning process at time intervals that can be set up,
independent from the head loss factor. The timer resets after every flushing cycle.
4. A signal from Continual flushing switch - This switch in the control board allows operation in continuous flushing mode; meaning,
the filter is flushing itself all the time regardless of flow rate or water quality.
Control system:
Two types of control boards are available: PLC Type and Relay Type. See Appendix A or B for details.

INSTALLATION
Design recommendations:
1. If flow increases and pressure drops dramatically for a long period of time during network filling -up, it is recommended that a
pressure sustaining valve is installed downstream. The pressure sustaining valve will ensure a controlled filling-up of the line.
2. If continual water flow is essential even during maintenance period, it is recommended that a manual or automatic by-pass is
installed, and the isolating valves will be used to isolate each filter unit.
3. In places where there is an expected temporary worsening of water quality, it is possible to operate an emergency flushing
program. In order to do so, a hydraulic controlled valve has to be installed downstream. For details, please consult the
manufacturer.
Installation instructions:
1. Install the filter horizontally in a way which will allow convenient approach and enough space to dismantle the filter for
maintenance purposes.
2. Ensure the direction of flow according to the arrows marked on the filter housing.
3. It is recommended to install a mechanical non-return valve downstream of the filter.
4. Connect a minimum of 2" pipe to the exhaust valve. The exhaust pipe should be designed so that it creates minimal resistance
to flow of 25 m3/h (110 USgpm).
5. If the system is designed to operate with working pressure higher than 6 bar (85 psi), it is recommended that a manual valve is
installed on the exhaust pipe, in order to enable regulation of the flushing flow rate.
6. The user should arrange suitable lighting at the area of the filter to enable good visibility and safe maintenance.
7. The user should arrange suitable platforms and safety barriers to enable easy access to the filter without climbing on pipes and
other equipment.
IMPORTANT !!
• Prevent static back pressure or reverse flow through the filter.
• Install a manual or a hydraulic valve downstream of the filter.
Electric wiring:
1. Install the control board in a dry and protected place (It is possible to order a special control board for out-door installation).
2. Power connection to the control board:
a. Connect a three-phase voltage source through a semi-automatic switch, or 16 Amp. fuse to the L1 L2 L3 inlet at the
terminal strip in the control board.
b. Earth the control board.
3. Power connection to the motor: Connect the drive unit to the control panel by means of a 4 x 2.5mm (12 or 14 AWG) wire in
flex-conduct. Use a long enough cable to allow removal of the drive unit and placing it near the filter for maintenance, without
having to disconnect it from the cable. (It is recommended that this installation meets or exceeds local or national electrical
codes, this is a "high" voltage connection).
4. Control wiring: Connect between the control junction box and the control board by means of 6 x 1.5 mm 2 (16 AWG) wire in flexconduct.
The numbers on the terminals in the board and in the junction box are identical.
Start-up and first operation
1. Make sure all the electric wiring is correct, according to the drawings supplied with the control board itself. The electrical
drawings in this manual are for reference only.
2. Switch the control & 24V circuit breakers and the motor protector to ON. The motor will start operating*.
The suction scanner shaft should turn clockwise and move towards the filter housing until it reaches limit switch "A". If the motor
rotates in the opposite direction, disconnect the electricity immediately and change the direction of the motor rotation by
changing between two phases.
The motor must stop when the magnetic disc reaches limit switch "A" and causes it to operate.
3. Operate a "dry" flushing cycle by pressing on the "TEST" push button. Make sure all flushing stages occur as described in the
filter description chapter of this manual.
4. Open the inlet valve to the filter, while the outlet valve remains closed or with an open by-pass valve (This will keep the flow in
the filter at a minimum), and operate a flushing cycle.
Make sure the exhaust valve opens and all stages of the flushing cycle are carried out. Attend to leakages, if any.
Close the 1/4" valve at the low pressure point of the pressure differential switch for 5 seconds. The PDS hand will move to the
red area and the filter will start the flushing process. Open the 1/4" valve.
5. Gradually open the outlet valve and/or close the by-pass valve. Operate the filter at the designed hydraulic conditions.
6. Set the timer for 6-8 hours.
7. Check and re-tight all bolts after the first week of operation.
* When using Control board type "C" (Relay type) it is necessary to press the "Test" push button in order to start the motor
operation for the first time.

APPENDIX A.
"PLC" CONTROL SYSTEM (TYPE "D" SAF SERIES)
Description of control panel components:
1. Pilot lights:
Yellow - lights ON when power is on.
Red - lights ON when the control panels enters malfunction mode.
2. Push buttons:
TEST Manual operation of a flushing cycle.
RESET - clears the malfunction mode.
3. Flushing counter:
Counts the flushing cycles that occurred. Used for follow-up on the system operation.
4. Timer T1 (0-30 hours):
Allows timed flushing cycles. The timer is reset with each flushing cycle.
To cancel timed flushing, set selector SW1 to "PRESS. ONLY".
Changing the switch to "CONT." will cause the filter to flush continuously regardless of pressure differential or
time.
5. Motor protector:
This switch protects the motor in case of short-circuit or overload. It is important to set amperage according to the
label of the motor. When this switch is tripped, the fault light will blink.
6. Contactors CU and CD:
Controls direction of motor rotation.
7. Transformer:
Electric supply to the various control components.
8. 2 x 6 Amp. and 1 x 4 Amp. Circuit breakers:
Short-circuit protection for the control system.
9. PLC:
A Programmable Logic Controller responsible for the control panel operation according to a preset program.
Stages of cleaning cycle:
1. The exhaust valve opens to atmosphere.
2. Five seconds delay.
3. The motor starts rotating the suction scanner shaft until it reaches limit switch "B" (T.L.S).
4. The exhaust valve closes.
The suction scanner remains at limit switch B until the next flushing cycle. In the next flushing cycle, it will move
from L.S B to L.S "A" (B.L.S).
In some versions of control panels, the suction scanner automatically returns to position "A" at the end of the
flushing cycle. In this case the flushing cycle always begins from L.S. "A" (B.L.S).
NOTE: The limit switches are wired as Normally Closed contacts (NC). Therefore, when the "Limit Switch Plate"
reaches the limit switch, the contact opens and the PLC receives "NO SIGNAL".
Requests for flushing cycle:
a. PDS (Pressure Differential Switch)
b. Timer 0-30 Hr.
c. TEST button activation
d. Continuous flushing
16
amiad filtration systems

PDS operation:
The PDS constantly monitors the pressure differential between the inlet and outlet of the "SAF" filter.
When the PDS senses a preset value (usually 0.5 bar=7 PSI) there is a delay of three (3) seconds before the flush
cycle begins. At the end of the cleaning cycle, if the pressure differential signal remains, the filter will continue to
clean itself for 15 minutes before entering into malfunction mode.
Timer operation:
Flush according to time is available through a built in timer. It is possible to preset the intervals between flush cycles,
regardless of the pressure differential.
The recommended default is between 6-8 hours.
In order to cancel the timer operation, simply turn the timer selector SW1 to its middle position.
"TEST" operation:
The "TEST" button activates a manual self -cleaning cycle, in order to test the filter operation.
Continuous flushing:
The filter flushes continuously regardless of pressure differential or time. It is recommended that this mode be used
for a limited duration only - in order to overcome extreme dirt load situations.
Malfunction modes:
The system recognizes two malfunction modes:
1) Mechanical fault
2) Clogging fault (DP Fault).
Mechanical fault:
Occurs under any of the following conditions:
a. The over load motor protector is tripped.
Find and correct the fault reason, clear the fault mode by pressing the O.L. motor protector to the ON position.
b. Limit switch failure.
The motor has been activated and there is no signal from a limit switch for more than 35 seconds. The problem
might be with one of the limit switches or the drive mechanism. Find and correct the fault, clear the fault mode by
pressing the RESET push-button.
c. Both limit switches signal "OPEN" simultaneously.
This may be a result of a limit switch failure, wrong wiring or wiring break off.
Find and correct the fault, clear the fault mode by pressing the RESET push-button.
d. The motor is rotates in the wrong direction.
The PLC recognizes this mode in case that CD (contactor down) is ON and a signal is received from limit switch
The following procedure will rectify this situation:
Manually activate whichever Contactor forces the driveshaft disk to rotate towards the halfway point between the
two limit switches. (Pressing the plastic bridge on the contactor with a small screwdriver can do this).
Turn off power to the control panel and reverse any two phases to change direction of rotation. (In a DC
controller, reverse the two wires to the motor).
Power up the controller and press the RESET button.
Note: Pressing the RESET button or turning power off and then back on without performing the above
mentioned instructions will NOT release the system from a fault condition!
In a mechanical fault mode, the fault light blinks.
17
amiad filtration systems

Clogging fault (DP Fault):
DP fault occurs when there is a continuous PDS signal for more than 15 minutes.
In this case the flushing cycle stops, the fault light turns on and the fault output is activated. The fault output of 24
VAC can activate an alarm system, automatic bypass, pump shut-off, etc.
The controller will also enter a DP fault when the filter is both in a mechanical fault mode and also receives a flush
request.
In order to clear the malfunction mode, press the "RESET" button.
Bridging positions 7A and 7B at the terminal strip will cause the controller to ignore the PDS malfunction; meaning,
the filter will continue the cleaning cycle as long as the PDS sends a signal. After 15 minutes, the red light will be lit
but the fault output will not be activated. Disconnecting the bridge between 7A and 7B will clear the fault mode and
the filter will return to normal operation.
General information
1. When power is first turned on, the PLC will check limit switch "A" to be sure it is "OPEN", if not the motor will
operate to move the "Limit Switch Plate" until it reaches the limit switch.
2. The flushing counter will operate at the end of each cleaning cycle. Reset the counter by pressing its red button.
3. PAUSE: Bridging positions 6A and 6B on the terminal strip pauses the cleaning cycle immediately. This function
applies only for special applications. Please consult the manufacturer or an authorized dealer for further
information.
4. "END OF CYCLE" PULSE: (Output O/1, terminals 10 & 11). A free potential output, which signals at the end of
each flushing cycle for 5 seconds. With this pulse it is possible to connect multiple controllers in series to allow
sequential flushing. In this case, connect terminals 10 & 11 to PDS inlet in the next controller of the series.
If one of the filters in the series is in malfunction mode the signal will be automatically transmitted to the next filter
in line.
5. "FLUSHING ON" SIGNAL: (Output O/1 + Input I/9 = ON, terminals 10 & 11) This configuration allows the
integration of a downstream pressure regulating valve or peripheral pump operation during the flushing cycle.
Output O/1 is activated one second before the beginning of the flushing cycle. This short delay allows a timer and
relay (optional) to activate the PAUSE circuit (input I/6) for the duration required by the downstream valve or the
peripheral pump.
Both optional features of output O/1 may also be used for information transmitting to a remote control center.
NOTE: Extra features to the control panel are available according to specific requirements. These features must be
defined in advance.
Startup Procedure:
1. Check and verify that wiring between the filter and the control panel is done according to the provided wiring
diagram.
2. Verify that the "Limit Switch Plate" is located halfway between the two limit switches and that the motor protector
(Over Load) is switched off.
3. Switch "ON" all circuit breakers (except the motor O.L.).
4. Set selector SW1 to the middle position (PD only).
5. Switch on the motor O.L. and watch the rotation direction of the motor. If the motor rotates counterclockwise i.e.
the suction scanner moves upward (outward the filter), stop it immediately by turning the O.L. to the off position.
Change the motor direction by switching between two phases.
If the motor rotates clockwise i.e. the suction scanner moves downward (inward the filter), let it continue until it
reaches the lower limit switch and stops.
6. Press the "TEST" push button and verify that the filter is functioning according to the above description.
7. Open the water supply and pressurize the system. It is highly recommended that first "wet" operation is done
with static pressure and no flow i.e. the outlet valve is open and the by-pass of the system is open.
8. Operate a flushing cycle by pressing the test push-button. Verify that everything is working properly as
described above.
9. Operate a flushing cycle by closing the 1/4" Manometer Valve of the PD switch for 5 seconds.
10. If everything is functioning as described, open the outlet valve of the filter, and gradually close the by-pass
valve.
11. Set T1 to 4 - 8 hours and turn selector SW1 to the upper position (PD & Time). Follow and monitor the
functioning of the filtration system, change T1 setting if required.

APPENDIX B.
"RELAY" CONTROL SYSTEM (TYPE "C" - SAF SERIES)
Description of control panel components:
1. Pilot lights:
Yellow - lights ON when power is on.
Red - lights ON when the control panels enters malfunction mode.
2. Push buttons:
TEST - Manual operation of a flushing cycle.
RESET - clears the malfunction mode.
3. Timer T0 (0-10 seconds):
PD delay timer. This timer should be set to 3-5 seconds.
4. Timer T1 (0-30 hours):
Allows timed flushing cycles. The timer is reset with each flushing cycle. To cancel timed flushing, set selector
SW1 to "PRESS. ONLY".
Changing the switch to "CONT." will cause the filter to flush continuously regardless of pressure differential or
time.
5. Timer T2 (0-10 X 0.1 Hr.):
PD fault timer. This timer should be set to 3 X 0.1 Hr. = 18 minutes.
6. Motor protector:
This switch protects the motor in case of short-circuit or overload. It is important to set amperage according to
the label of the motor. When this switch is tripped, the fault light will turn on.
7. Contactors CU and CD:
Controls direction of motor rotation.
8. Transformer:
Electric supply to the various control components.
9. 2 x 6 Amp. and 1 x 4 Amp. Circuit breakers:
Short-circuit protection for the control system.
10. "DP", "LSU", "LSD" and "F" Pilot relays:
The relays are used to carry out the control panel activities
Stages of cleaning cycle:
1. The exhaust valve opens to atmosphere.
2. The motor starts rotating the suction scanner shaft until it reaches limit switch "B" (Top L.S).
3. The exhaust valve closes.
The suction scanner remains at limit switch B until the next flushing cycle. In the next flushing cycle, it will move
from L.S B to L.S "A" (Bottom L.S).
NOTE: The limit switches are wired as Normally Closed contacts (NC). Therefore, when the "Limit Switch Plate"
reaches the limit switch, the contact opens and the relay is de-energized.
Requests for flushing cycle:
a. PDS (Pressure Differential Switch)
b. Timer 0-30 Hr.
c. TEST button activation
d. Continuous flushing
22
amiad filtration systems

PDS operation:
The PDS constantly monitors the pressure differential between the inlet and outlet of the "SAF" filter.
When the PDS senses a preset value (usually 0.5 bar=7 PSI) there is a delay of three seconds (T0) before the flush
cycle begins. At the end of the cleaning cycle, if the pressure differential signal remains, the filter will continue to
clean itself for the time duration preset at T2 (recommended 18 minutes) before entering into malfunction mode.
Timer operation:
Flush according to time is available through a built in timer. It is possible to preset the intervals between flush cycles,
regardless of the pressure differential.
The recommended default is between 6-8 hours.
In order to cancel the timer operation, simply turn the timer selector SW1 to its middle position.
"TEST" operation:
The "TEST" button activates a manual self-cleaning cycle, in order to test the filter operation.
Continuous flushing:
The filter flushes continuously regardless of pressure differential or time. It is recommended that this mode be used
for a limited duration only - in order to overcome extreme dirt load situations.
Malfunction modes:
The filter will enter into a malfunction mode under the following conditions:
1. When the motor protector is activated due to over load or short circuit in the motor.
2. When the PDS transmits a continuous signal for a longer period than it was preset at T2.
3. Both limit switches signal "OPEN" simultaneously.
This may be a result of limit switch failure, wrong wiring or wiring break off.
When the filter has entered a malfunction mode, a red light is lit on the control panel door, flushing stops and fault
outputs are activated.
Fault output No. 1 in positions F/1 & 2 at the terminal strip is "Dry Contact", suitable for connecting to an external
control system.
Fault output No. 2 in positions F/3 & 4, supplies 24 V AC in order to activate a solenoid for an automatic by-pass,
main inlet valve or relay of a pump.
In order to cancel malfunction mode, push the "RESET" push button.
PLEASE NOTE:
In case that power supply is connected while the suction scanner does not touch any of the two limit
switches, the motor will start only when the next signal for flushing is received.
Startup Procedure:
1. Check and verify that wiring between the filter and the control panel is done according to the provided wiring
diagram.
2. Verify that the "Limit Switch Plate" is located halfway between the two limit switches and that the motor protector
(Over Load) is switched off.
3. Switch "ON" all circuit breakers (except the motor O.L.).
4. Set selector SW1 to the middle position (PD only).
5. Switch on the motor O.L., press the TEST push-button and watch the rotation direction of the motor. If the motor
rotates counterclockwise i.e. the suction scanner moves upward (outward the filter), stop it immediately by
turning the O.L. to the off position. Change the motor direction by switching between two phases.
If the motor rotates clockwise i.e. the suction scanner moves downward (inward the filter), let it continue until it
reaches the lower limit switch and stops.
6. Press the "TEST" push button and verify that the filter is functioning according to the above description.
7. Open the water supply and pressurize the system. It is highly recommended that first "wet" operation is done
with static pressure and no flow i.e. the outlet valve is open and the by-pass of the system is open.
8. Operate a flushing cycle by pressing the test push-button. Verify that everything is working properly as
described above.
9. Operate a flushing cycle by closing the 1/4" Manometer Valve of the PD switch for 5 seconds.
10. If everything is functioning as described, open the outlet valve of the filter, and gradually close the by-pass
valve.
