Cell682 User’s Manual
In a drain application, force the input to be above the Lead level and the first
pump should turn on. If you then set the input above the Lag level, the second
pump should also turn on. Setting the input below the Pumps-Off setting will
turn both pumps off. In a fill application, setting the input below the lead level
will turn the first pump on. Setting the input below the Lag level will turn on
the second pump. Setting the input above the pumps-Off level will turn off both
pumps.
Once you have confirmed that the Cell682 is controlling the system properly,
allow the system to operate automatically. Observe a complete Drain or Fill cycle
and verify that the system is operating as required.
