The YSC-3EX controller is engineered to provide speed control of a Solenoid-operated air operated double diaphragm pump. You can set the speeds in a range of 1 - 400 cycles per minute. A cycle is defined as emptying both pump chambers once. The system requires 110 volts AC (input) (220-240 also available) to power it and delivers 12 (standard) or 24 (optional) volts DC to the pump solenoid. You must use the appropriate pump solenoid* when using a YSC-3EX. The system is programmed using the 4-button keypad on the enclosure.
The connections for remote usage are a terminal strip also on the circuit board. The circuit board is installed in a NEMA 4X plastic enclosure. The unit always comes up in the last preset it was used in and is ready to run seconds after power is applied.
