Battery Voltage
The normal voltage level of the battery ranges from 11 V to 15.5 V. A voltage level
below
11 V
indicates a discharged battery. A voltage level
above
15.5 V indicates an open fuse, a
disconnected battery, or a defective charger.
Valve Positions
The controller can be configured so that the valve will be driven fully open, fully closed, or will
be disabled upon an AC power failure.
Open:
The controller opens the valve at power down. In the event that the valve is already
open, the module provides power for approximately 1 second before turning off.
Closed:
The controller closes the valve at power down. In the event that the valve is already
closed, the module provides power for approximately 1 second before turning off.
Disable:
The option is disabled and will not perform any function at power down. The
controller turns off in a normal manner.
When the controller is configured to open or close the valve, it will perform the operation
whenever power to the controller is turned off, regardless of whether the power is turned off via
the power switch or by a power failure.
Note
If for any reason the controller cannot open or close the valve within 30
seconds of a power failure, the battery back-up module automatically
turns off. This prevents the battery from discharging when no valve is
present or if the valve is defective in some way.
