DESCRIPTION OF FILTER OPERATION
Filtering process:
The EBS is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by an electric motor. The EBS is
designed to work with various types of screens in filtration degrees from 500 to 10 micron, and is available in 8", 10", 12" and 14"
inlet/outlet diameter.
The water enters through the inlet pipe into the fine screen from inside out. The "filtration cake" accumulates on the fine screen
surface and causes head loss to develop.
Self-cleaning process:
The EBS 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 scanner rotation is operated by a 2-way (fwd/rev) drive unit which is attached to the scanner by a threaded shaft, providing 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 out of the filter.
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 the 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 operation mode on
the HMI.
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. In case that there is HMI, the relevant fault error will be displayed.
The filtration system may enter a malfunction mode in the following cases:
1st. When there is a continuous signal from the pressure differential switch for duration of more than 15 minutes. This means that
the self-cleaning process is not successful.
2nd. When the motor protector was activated, either manually or due to overload.
3rd. As a result of 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.
Stages of cleaning cycle:
Under normal operating condition the electrical control panel operates the "EBS" filter in the following manner;
1. The exhaust valve opens to atmosphere.
2. Five seconds delay.
3. The motor starts rotating the suction scanner shaft upward until it reaches the upper limit switch.
4. The exhaust valve closes.
5. Two seconds delay.
6. The motor starts rotating the suction shaft downward until it reaches the lower limit switch.

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 of the filter. 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.
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 of the filter. For details, please
consult the manufacturer.
Installation instructions
1. Before beginning the installation process, carefully read the safety instructions in chapter 2 of this document and make sure
that all the workers at the installation site are fully aware of and comply with, these and any other local safety instructions.
2. Select a convenient location for the installation of the filter where operation and maintenance will be optimal. It is
recommended that a standard and safe lifting auxiliary is available for maintenance.
3. Install the filter vertically. Please note that a minimum clearance of 300 mm (12 In.) (Not including a crane) is required in
order to allow disassembly of the unit.
4. Ensure that the direction of flow is aligned with the arrows marked on the filter housing. (Flow outlet will always be from the
side; flow inlet is from the bottom).
5. Installation of a mechanical non-return valve downstream of the filter is required.
6. If possible, prior to installing the filter, thoroughly flush the main line at the connection point in order to remove large objects
that may damage the filter’s internal mechanism.
7. Install a drainage pipe to the exhaust valve. Minimum 3" diameter for a maximum pipe length of 20 meters (60 feet), for
longer drainage, 4" pipe diameter must be used for a maximum length of 40 meters (120 feet). Please note that no restriction
is allowed on the drainage pipe. For special applications, please consult the manufacturer.
8. If the system is designed to operate with working pressure higher than 4 bar (56 psi), it is recommended that a manual
valve is installed on the exhaust pipe, in order to enable regulation of the flushing flow rate & pressure.
9. The user should arrange suitable lighting in the vicinity of the filter to enable good visibility and safe maintenance.
10. The user should arrange suitable platforms and safety barriers to enable easy access to the filter without climbing on pipes
and other equipment. All such equipment should comply with the safety clauses of the relevant local standards.
IMPORTANT!!
Prevent static backpressure or reverse flow through the filter.
Install a non-return valve at the outlet of the filter.
Install a manual or a hydraulic valve downstream of the filter.
Electric wiring
1. All electrical works at the installation site must be done by a qualified and authorized electrician only. Make sure that this
electrician is fully aware of all the relevant safety instructions.
2. Install the control board in a dry and protected place (In out-door installation sites make sure to use a special control board
for out-door installation).
3. 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.
4. Power connection to the motor:

EBS 10K Flat Lid 910101-000595 / 07.2019 Page 11 of 28
Connect the drive unit to the control panel by means of a 4 x 2.5 mm (12 or 14 AWG) wire in flex-conduct. Use a long enough
cable to allow the drive unit to be removed and placed 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).
5. Control wiring:
The connection between the control junction box and the control board should be by 6 x 1.5 mm 2 (16 AWG) wire in flex-
conduct. The numbers on the terminals in the board and in the junction box are identical.
COMMISSIONING, START-UP AND FIRST OPERATION

Before beginning any troubleshooting, carefully read the safety instructions chapter of this document and make sure that all the
workers at the filtration site are fully aware of and comply with, these and any other local safety instructions.
The filtration system may enter a malfunction mode in the following cases:
Symptom
Remarks and Actions
Fault due to continuous signal from the
pressure differential switch for duration of
more than 15 minutes.
The fault indication lamp is lighted in red
This fault means that the self-cleaning process is not successful.
This fault may be caused by one of the following reasons:
•The filter is clogged due to heavy dirt load or too high water flow rate.
Close the filter’s downstream valve.
Press the reset button to reset the fault mode. The fault indication lamp
is turned off.
Perform few consecutive manual flush cycles and monitor the PD signal.
Once the filter is clean gradually open the downstream valve and
monitor the PD and the flow-rate. Make sure that the filter doesn’t
exceed its designated flow-rate.
•The PD switch is faulty.
Ask your qualified electrician to check the PD connections and operation.
Replace the switch if found faulty.
The motor protector was activated
The fault indication lamp is blinking in red
This fault means that the motor was operated under too high load.
Note: All the following checks and actions should be done by a qualified electrician
only.
A. Check the motor power consumption when not loaded.
B. Check the limit switches for correct operation and verify that each one of
them stop the motor at its designated point.
C. Verify 3 phase 380VAC power supply to the control board and the motor.
D. Disconnect the drive unit from the suction scanner shaft and verify free
turning of the suction scanner.
Note: If during this fault a request for flushing is received (Manual, Time or DP) the
blinking lamp switches to constant red.
Malfunctioning limit switches
The fault indication lamp is blinking in red
Faulty limit switch may not stop the motor at the right point and therefore the motor
protection may be activated.
Receiving signal from both limit switches at the same time causes fault
A. Check that the limit switches are not mechanically stuck.
B. Ask your qualified electrician to check the wiring and the functionality of the
limit switched.
Note: If during this fault a request for flushing is received (Manual, Time or DP) the
blinking lamp switches to constant red.

DISMANTLING AND ASSEMBLING THE FILTER COMPONENTS
Opening the filter and disassembling its inner components is necessary for changing screens, periodic maintenance and repairs.
Prior to opening the filter it is recommended to initiate a flushing cycle by pressing the "TEST" push button.
Before beginning any maintenance procedure, carefully read the safety instructions in chapter 2 of this document and make sure that
all the workers at the filtration site are fully aware of and comply with, these and any other local safety instructions.
Dismantling:
1. Disconnect the electrical power and lock the main switch.
2. Close off the water and drain the filter housing.
3. Disconnect the compressed air supply, lock the main switch and release the residual pressure.
4. Unscrew the bolts of the exhaust valve, disconnect the air pressure tubes and remove the valve.
5. Unscrew bolts (29) and remove the drive unit (25). Put the drive unit on a dry and protected surface near the filter. If the
electric cable is not long enough, disconnect it from the motor.
6. Pull out the split pin (23) from the connecting pin (22) then pull out the connecting pin. If the connecting pin is not facing one
of the shaft housing windows, turn the drive shaft (3 on page 23) a little. Use 17mm or 11/16 spanners.
7. Turn the drive shaft (3 on page 23) counter clockwise so that it will be separated from the suction scanner shaft (2 on page
24).
8. Unscrew bolts (10 on page 23) and remove the limit switches sling (9 on page 23) without disconnecting and changing the
limit switches position.
9. Unscrew bolts (21) connecting the shaft housing (13) to the filter lid (9).
10. Pull up the shaft housing. Put it near the filter, make sure not to damage the limit switches electric wires. If necessary,
disconnect the wires from the connecting box (37). (Do not forget to mark all wires for proper reconnections).
11. Unscrew the housing bolts (17) and pull the lid using a crane or other lifting device, make sure that it is located exactly above
the lid center. Make sure that the lifting device is a standard device, operated by an authorized operator in accordance to all
relevant safety standards. Never lift any filter component above people or equipment.
Note: the lid must be lifted vertically while maintaining its horizontal position; this prevents damage to the suction scanner
and the upper bearing seals.
12. Pull the scanner (14) and the screen (7) (including screen seals 6); make sure that extracting the screen is done according to
the following description.

Extracting the Screen
Before handling the screen, carefully read the safety instructions chapter of this document and make sure that all the workers at the
filtration site are fully aware of and comply with, these and any other local safety instructions.
Please note that the screen is heavy and in order to avoid damage and injury it should be lifted only with Amiad’s standard Extractor
and a standard lifting device operated by an authorized operator.
1. Clean and dry the rubber pads on the Extractor
2. Fold the Extractor upwards (Figure 1).
Figure 1
3. Insert the Extractor into the screen, about a quarter from top. Make sure that the extractor cushions do not touch the stitch
found along the screen interior.
4. Pull the extractor up so that it is firmly set against the inside wall of the Screen (Figure 2)
Figure 2:
5. Attach a lifting device to the ring on the Extractor, and extract. Never lift the screen above people or equipment.

Reassembling the "EBS" filter:
Before reassembling, visually check that all components are complete and in good mechanical condition.
Before reassembling, carefully read the safety instructions in chapter 2 of this document and make sure that all the workers at the
filtration site are fully aware of and comply with, these and any other local safety instructions.
1. Install the seals (6) on the screen (7) and insert the screen into the filter housing (1). Make sure to handle the screen
according to the description provided in the “Extracting the Screen” section above.
2. Position the scanner (14) in the filter housing. Make sure the lower shaft goes through the bearing (4).
3. Apply some grease to the suction scanner shaft (2 on page 24) and to the O-rings (3 and 5).
4. Lower the filter lid (9) carefully toward the filter housing (1) in a horizontal position. Make sure the lid is centered with the
suction scanner.
5. For centering the lid properly use the two centering sleeves together with two bolts (17) in opposite positions.
6. Screw the rest of the housing bolts (17). Tightening opposite positioned bolts will achieve proper sealing.
7. Locate the O-ring (12) in its groove under the shaft housing (13). Place the bolts (21) but do not yet tighten them firmly.
8. Turn the drive shaft (3 on page 23) clockwise until it reaches the suction scanner shaft. Insert the connecting pin (22) into the
hole in the drive shaft through the suction scanner shaft hole.
9. Insert the split pin (23) in its original position.
10. Make sure that the drive shaft key (24) is in its place. Apply grease to it and reassemble the drive unit (25).
11. Firmly tighten the shaft housing bolts (21) and the drive unit bolts (29) in a controlled and balanced method.
12. Reassemble the limit switches sling (9 on page 23); make sure the limit switches (22 on page 23) are tight in their place.
13. Reassemble the exhaust valve and air tubes.
14. Make sure that all bolts are tightened.
15. Switch on the compressed air supply and switch on the power. The motor will run until limit plate (2 on page 23) reaches the
lower limit switch.
16. Press the "test" push button and make sure the filter works according to the stages of the cleaning cycle.
