CUB-0001
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 ener-

gized 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.

Transducer Back-Up Control
Single Float Operation:
With power applied to the Back-Up Controller when the float switch closes, the output to the lead pump will be energized and Time Delay B will be initiated. If the float switch remains closed and Time Delay B times out, the output to the lag pump will be energized.
When the float switch opens, indicating that the tank is being pumped down, Time Delay A is initiated and the output to the lead pump (and the lag pump, if it was energized) will remain energized. After the Time Delay A has been completed and the float switch is still open, the output to the pump(s) will de-energize.
If the float switch re-closes during Time Delay A, the timer is reset and the output(s) that is energized remains energized. When the float switch re-opens, Time Delay A will start again. At the completion of the time delay, the pump output(s) will de-energized. After the Time Delay A is over and the pumping cycle is completed, the next time the float switch closes, the output to the lag pump in the first cycle will be energized. This provides alternation between pumping cycles. Each time a pumping cycle is complete, the pump output(s) for lead and lag will alternate.
To have the Back-Up Controller operate in the Single Float operation, only connect to float switch to the “HI” input. When the “HI” input closes without an “OFF” input closure, the Back-Up Controller will assume that the system is operating as a Single Float.
CUB-0001
Dual Float Operation:
With power applied to the Back-Up Controller when the first float switch input closes connected to the “OFF” input, nothing happens to the outputs.
When the float switch input closes connected to the “HI” input, the output to the lead pump will be energized and the “HI” float switch inputs both remain closed and Time Delay B times out, the output to the lag pump will be energized. If the “OFF” float switch input remains closed and the “HI” float switch input opens before Time Delay B times out, the output to the lag pump will not be energized.
When the “OFF” float switch opens, the output to the pump(s) will de-energize. Once energized, the output(s) to the pump(s) re­mains energized until the “OFF” float switch opens. After the pumping cycle is completed, the next time the “HI” float switch input closes, the output to the lag pump in the first cycle will be energized. This provides alternation between pumping cycles. Each time a pumping cycle is complete, the pump output(s) for lead and lag will alternate.
Whenever the “OFF” float switch input closes before the “HI” float switch input closes, the Back-Up Controller will assume that the system is operating as a Dual Float.
Time Delay B will be initiated. If the “OFF” and
Alarm Reset:
Once the Back-Up controller has sensed a float switch input, indicating a possible failure of the transducer based system; the alarm output contact will close. To reset the alarm output contact the power must be removed from the Back-Up controller for 5 seconds and then re-applied with no float closure inputs.
