A. PANEL CONTROLS DESCRIPTION.
1. MAIN , Toggle switch 0-1.
Enable Connection of the MAIN voltage supply to the control unit.
Light indicator (Green) – indicates 24VDC internal supply.
2. FLUSH , Push-button switch (Yellow) , Enable manual flushing.
Note that FLUSH indicator will lit during flushing process.
3. FAULT , Push-button switch (RED) , Pressing this switch in FAULT state
(While red indicator illuminates) will reset the control unit.
B. NTERNAL CONTROLS DESCRIPTION.
1. PLC , Programmable logic controller.
(CROUZET XD10 /24VDC , Cat. No. 88 974 144).
2. PS1 , Low voltage 24VDC Power Supply.
3. OL1 , Motor over load protection 1.0-1.63 amp. with aux. contacts.
4. C1 , power relay which controls filter motor.
5. F1 , 1ampK. Half Automate Circuit breaker which serve as a main protect for PS1.
6. F2 , 1ampK. Half Automate Circuit breaker which protect against accidental short
circuit on the PLC / SV solenoids/outlets. (24VDC)
7. FPLC , 1.6ampT Fuse which protect against accidental short circuit on the PLC.

solenoid/outlets. (24VDC)
C. TERMINAL CONNECTIONS.
TB 1-4
L1/L2/L3+ Gnd , 115-230-380-420-440-480V , 50/60 hz. supply voltage
inlets.
TB 5-8
U/V/W 230 -380-420-440-480V + GND, 3 phase,50/60 hz. motor supply
voltage outlets.
TB 9 / 10 SV, Flushing Solenoid outlet. (24VDC/10W)
TB 11 / 12 DP, Differential Pressure switch contacts inlets. (N.O)
TB 19 / 20 REM , Remote flush inlets. (N.O. Pulse activated , Voltage free contacts
inlets.)
This inlet is pulse activated through voltage free external contacts with
pulse duration of at least 100 msec.
TB 22 / 23 FLUSH , Aux. Flush signal contacts outlets. (N.O)
TB 24 / 25 FAULT , Aux. Fault signal contacts outlets. (N.O)
WARNING
1. Aux. Inlets REM are connected to PLC inputs.
BE SURE to connect Voltage free Contacts or switches to this inlets.
In case of signaling through remote system outlets, use auxiliary
relays (K) to isolate between remote system voltage and PLC inputs.
2. FLUSH and FAULT aux. signal is voltage free N.O. contacts that
withstand max. of 230V / 2Amp. That must be protectors accordingly.
