3. Connect the Flushing solenoids/Differential pressure switch/Limit switches cable using
9-12 x 0.75mm cable, between control unit and filter junction box terminals.
Control board
TB9 - Solenoids common
TB10 - SV1 Regular flushing solenoid ,live
TB11 - SV2 Emergency flushing solenoid ,live
TB13 - differential pressure switch live.
TB14 - differential pressure switch common
TB15 - LSI/LSO Sensors + supply wire (Brown).
TB16 - LSI/LSO Sensors - supply wire (Blue ).
TB17 - LSI Sensor signal wire (Black).
TB18 - LSO Sensor signal wire (Black).
4. Remote & Enable inlets.
Warning – Since remote and enable inlets are connected to the PLC inputs
Remote & Enable signals MUST BE applied through voltage free contacts.
A. A. Remote inlet - TB 19/20 , Is pulse activated, (Min. of 250 msec. pulse Duration), and will
activates the flushing mechanism only at inlet transition from OFF to ON (Short circuit).
B. Enable inlet - TB 19/21 , Short circuit between this inlets will inhibit Any kind of flushing
cycle.
5. FLUSH outlets – TB 22/23 (Voltage free contacts). Used mainly to enable external
buzzer/lamp or as a FLUSH signal to remote/main system.
6. FAULT outlets – TB 24/25 (Voltage free contacts). Used mainly to enable external
buzzer/lamp alarm or as a FAULT signal to remote/main system.
NOTE that flush and fault signals can withstand max. voltage/current 220V/2amp
and MUST BE protected accordingly against accidental short circuit.
