SIStec PC-1 24VAC/DC Pump Cycling Controller

Features

• The SIStec PC1 electronic pump controller automatically regulates the ON and OFF periods of pump equipment, by monitoring the current flow of the pump while operating under normal load conditions and switching the pump OFF when the sump runs dry


• The pump is then restarted after a time calculated from the condition of the jumper settings and the amount of time taken to drain the sump


• In this way a regular ON OFF cycle is maintained and automatically adjusted to balance the flow rate of the pump and the flow rate into the sump


• Power for the controller is connected to terminals 1 and 3


• The current transformer is connected to terminals 9 and 10


• The control circuit for the pump motor is connected to the normally closed relay output terminals 9 and 10


• The cycle time selection links are connected between terminals


• Loosten the SET CURRENT locking nut


• Rotate the SET CURRENT control screw fully counter clockwise


• Start the pump, and once it is no longer pumping fluid, rotate the SET CURRENT screw slowly


• Clockwise until the pump stops


• The Rest LED will then come on


• Tighten the SET CURRENT locking nut


• The pump will restart once the rest time has expired


• The Rest LED will go out, and the controller will automatically monitor and regulate the pump operation


• When de-energised the output relay is normally closed


• The pump will continue to run if power is removed from the controller


• The SIStec PC1 pump controller can be secured to a standard 35 mm DIN rail or screwed to a plate


• Using two M4 or M5 screws through holes at the rear of the case
