A. PANEL CONTROLS DESCRIPTION
1. Toggle switch - Marked MAIN
Enable Connection the line voltage supply to the control unit.
2. Light indicator (L1 , Green) – Marked ON , indicates 24Vac internal supply.
3. Push-button switch (L2/S2 , Yellow) - Marked FLUSH.
Enable manual flushing while FLUSH indicator will lit during flushing cycle.
4. Push-button switch (L3 ,RED) - Marked FAULT .
FAULT indicator lit on system fault state.
Pressing the FAULT sw. in FAULT state will reset the control unit and resume operation.
B. INTERNAL CONTROLS DESCRIPTION.
PLC , Programmable logic controller. (FATEK FB's 14MA with BPEP display).
1. TR1 , Isolated transformer with multi-voltage inlets, Which enables use of different 3 phase line
Voltage supply (220-380-420-440-480V) to 150Vac/20VA fixed outlet for the PLC and
24Vac/50VA fixed outlet for the control voltage and the solenoids.
2. OL1 , Motor over load protection 1-1.6amp. with aux. contacts.
3. C1A/C1B , power relays which controls filter motor movement.
4. F1 , 1amp. Circuit breaker , serve as a main protect for the PLC & TR1.
5. F2 , 2amp. Circuit breaker , protect against accidental short circuit on the SV1 - SV3
solenoids/outlets. (24Vac).
6. K1 , serve as a fault auxiliary relay that activate on fault state and can drive external load (buzzer
etc.) through it's Normally Open/close contacts.
7. K2 , serve as a FLUSH auxiliary relay that activate on flush state and can drive external load
(buzzer etc.) through it's Normally Open/close contacts.
C. TERMINALS CONNECTION.

TB 5/6/7/8 GND/U/V/W , 220-480Vac + GND, 3 phase , 50/60 hz. motor supply voltage outlets.
TB 9/10 SV1, Regular flushing Solenoid outlets. (24VAC/10-25W)
TB 9/11 SV2 , Emergency flushing Solenoid outlets. (24VAC/10-25W)
TB 9/12 SV3 , FAULT or DOWN STREAM Solenoid outlets. (24VAC/10-25W)
TB 13/14 DP , Differential Pressure switch contacts inlets. (N.O)
TB 15/16/17 L.S.I. , Motor inner limit sensor (or switch) inlets.
TB 15/16/18 L.S.O., Motor outer limit sensor (or switch) inlets.
TB 19/20 REM , Remote control contacts inlets. (N.O)
This inlet is pulse activated through voltage free external contacts with pulse
duration of at least 100msec.
TB 19/21 ENA , Enable system control contacts inlets. (N.O)
A short circuit at this inlets through voltage free external contacts will disable the
flushing mechanism.
TB 22/23 FLUSH signal contacts outlets. (N.O)
TB 24/25 FAULT signal contacts outlets. (N.O)
