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 Down
Select Floats or Level Probe Inputs
Select Sensitivity for Level Probe
Select Alarm Indication Reset (Manual or Automatic)
Select Serial Communication Parameters
