The DUPLEXER (010-120-122P) is a low cost SCADA ready plug-in pump controller designed to perform level control for duplex lift station applications. The level inputs of this dual pump controller can be connected to either four float switches or to a conductance probe. This 2 pump controller provides a 10 second power-up start delay, 5 second lag pump delay, and duplex alternation. LEDs provide power on status, level input status, pump call status, and high level alarm status indication. Pump 1 & 2 call and high level alarm relays are provided. HOA and lead select toggle switches are also provided.

Additional Description

Additional Description

N/A The high level status indication latches upon high level, until reset by pressing the reset push-button (the relay does not stay latched). Level simulation is accomplished by pressing and holding the push-button. Releasing the push-button allows the simulated level to return to normal. Connecting the serial port to a SCADA system allows the lift station to be monitored and controlled remotely. By connecting a programming device to the serial port (MPE p/n TSID), a number of settings may be accessed to customize the unit.
