|The controller shall monitor the level in the lift station via an analog input signal from a level or pressure transducer. There shall be 5 sets of limits specified in engineering units for the following control/alarm settings:
- Low Level: Alarm
- Off: Turn all active pumps off
- Lead On: Turn lead pump on
- Lag On: Turn lag pump on

|The controller shall monitor 3 float switches to control the running of the pumps and up to 2 additional floats for Low and High Alarm.
|When a pump is selected for Automatic operation (HOA in Auto mode), the pump shall be started and stopped by the controller.
When the Lead On condition exists, the controller shall attempt to start the Lead pump. If the Lag On condition exists indicating additional pumping capacity is needed, the controller shall start the Lag pump.
If the Lead or Lag pumps do not respond, the Controller should sense this through a Motor Starter failure input specific to each pump and provide an alarm signal and call out.
The Controller shall display the number of pump starts and the total elapsed run time for each pump on a text display.

A pump shall be able to be started from the keypad manually if configured for Automatic operation.
Once a pump is turned off, the controller shall keep it off for a predetermined period of time before it is permitted to restart. This period of time shall be operator adjustable from the local keypad.
If the High Level float switch becomes active, the controller shall turn the next pump in the sequence on/off regardless of the level indicated by a level transmitter or other float switch. The pump shall run until either an Off or Low/High Level condition exists. If the High Level float became active and neither pump was already running, then the controller shall turn both pumps on/off, waiting a predetermined period of time between the pump starts. This period of time shall be operator adjustable from the local keypad.
Both pumps shall have independent maximum on timers so that the pumps will shut off in the event that no Off or Low/High Level condition exists. Timer values shall be operator adjustable from the keypad.
If a Lag On float switch becomes active and the Lead On float switch was not active, the controller shall turn both pumps on, waiting a predetermined period of time between the pump starts.
If an over temperature input on the controller is activated, then that pump will be shut off and not run again until the over temperature condition clears. During the over temperature a unique alarm condition for that pump will exist, an LED will illuminate and an alarm callout will be enabled.
If a motor starter failure input on the controller is activated, then that pump will be shut off and not run again until the motor starter failure condition clears. During the motor starter failure a unique alarm condition for that pump will exist, an LED will illuminate and an alarm callout will be enabled.
If the phase monitor input on the controller is activated, then both pumps will be shut off and not run again until the phase monitor condition clears. During the phase monitor failure a unique alarm condition exists for the station, an LED will illuminate and an alarm callout will be enabled.
If a seal failure input on the controller is activated, then the pump will continue to run, an LED will illuminate and an alarm callout will be enabled.

If the controller is not acknowledged during the call, it shall hang up, wait from 1 to 3600 seconds and then dial the next number in its phone list. If a successful acknowledgment occurs, the controller shall give a sign-off message, hang up and then wait a user-programmed period of time for the alarm conditions to be corrected. If this period of time elapses and the alarm condition(s) still exist, the controller shall begin the alarm notification cycle again.
The controller shall initiate a callout sequence upon loss of primary power.
