Operation
The CUB-0001has been designed to operate as a Back-Up Controller to a transducer based system. If the transducer fails, the Back-Up Controler will allow the system to continue to operate based on a single or dual float switch inputs and activate an alarm contact.
Single Float Input
With supply power available, when the float switch input closes, a time delay is initiated. If the switch stays closed longer than the time delay, the output to pump motor #1 is energized and the alarm contact closes. When the float switch input opens, a second time delay is initiated. If the float switch remains open when the second time delay is completed the Pump output will open. The alarm contact will remain energized until power is removed and re-applied with no float switches closed. On the next cycle, pump #2 will be started first, providing for alternation.
Dual Float Inputs
With supply power available, when the “HI” float switch input closes, the output to pump motor #1 is energized, the alarm contact closes and a time delay is initiated. If the “HI” input stays closed longer than the time delay, the output to pump motor #2 is energized. If the “HI” float switch input opens before the time delay is completed, the lag pump motor is not activated. When the “OFF” float switch input opens, all pump motot outputs are de-energized. The alarm contact wil remain energized until power is removed and re-applied with no float switches closed. On the next cycle, pump #2 will be started first, provideing for alternation.
