A. PANEL CONTROLS DESCRIPTION.
1. Main switch - Marked [ MAIN ]
Enable Connection of the LINE voltage supply to the control unit,
at this state green lamp indicator [ ON ] will lit.
2. Lamp indicator (Green) - Marked [ ON ]
Indicates 24Vac internal supply.
3. Lamp indicator (Red) - Marked [ FAULT ]
Indicates MOTOR over load failure. (Flushing disabled!)
4. Lighted Push-button switch (Orange) - Marked [ FLUSH ]
Enable filter manual FLUSH operation.
B. INTERNAL CONTROLS DESCRIPTION.
1. OL , Motor over load protection 0.63-1amp. with aux. contacts.
2. e1 , 1 amp. Line protectors that serve as a main protect for the control unit.
3. e2 , 2 amp. Line protector which serve as a 24Vac protect for the control unit.
4. C1 , power relay which controls filter motor.
5. TR1 , Multi voltage / 24Vac transformer.
6. TP , Sets Differential pressure switch sense time.
7. TF , Sets the flushing time.
8. TD , Sets the interval time between flushes.
C. TERMINAL CONNECTIONS.
TB 1-4 : Line supply 380-480Vac+GND,3 phase,50-60Hz. inlets.
TB 5-8 : 380-480Vac+GND,3 phase,50-60Hz. M1 - motor supply voltage outlets.
TB 9/10 : SV , Flushing solenoid outlets. (24V/10W COIL)
TB 11/12 : DP , Differential pressure switch inlets.
TB 13/14 : SET inlets , enable/disable interval timer TD.
D. INSTALLATION.
General – The control unit & Filter junction box are supplied with 16mm flexible conduit glands.
1. Connect the line supply cable (4x1-1.5mm) to the control unit terminals :
IMPORTANT ! Line supply MUST
be protected by 3x4amp. Protectors.
TB1 - GND. wire.
TB2 - R Phase wire.
TB3 - S Phase wire.
TB4 - T Phase wire.
Warning ! The control unit is wired & tested with 380V phase supply Voltage.
For other phase supply voltage TR1 must be wired accordingly :
380 V -------------------------------- TR1 tags No. 1 & 2
415 - 420 V ------------------------- TR1 tags No. 1 & 3
