The Simplexer Controller (010-120-121P) is a plug-in controller for single pump control operation. The controller’s inputs shall be designed to accept either float switches or a conductance level probe input. The Simplexer Controller shall be UL508 Listed, SCADA ready, with modbus protocol, and be able to perform either pump-up or pump down control.

Fault Codes:
The Controller shall have a 12 pin base to mate with a SD12-PC socket, and have either an RS232 Serial Port or Ethernet port for its MODBUS SCADA connection.The Push-to-Test push-button shall allow the operator to test the automatic pump call function of the unit, as well as reset the high level alarm. By depressing and holding the Alarm / Push-to-Test Push-button, the unit shall automatically step through the level indications and the pump run and alarm functions. A Push-to-Test feature that only tests the Off and Lead inputs shall not be considered equal.The level input out-of-sequence logic shall compensate for float switch failure, or skipped level probe input conditions, and allow for continued pump operation. Internal registers shall allow SCADA to monitor Simplexer Controller inputs for an out-of-sequence condition, and shall also allow for the ability to store and reset this information.The controller shall contain the following setup features, available by accessing the serial port:Select Pump Up or Pump DownSelect Floats or Level Probe InputsSelect Sensitivity for Level ProbeSelect Alarm Indication Reset (Manual or Automatic)Select Serial Communication Parameters
The Controller shall be designed to simplify control panel construction by incorporating the following features:
