CONTROL OPERATION DURING A POWER FAILURE
The 5810XTR2 valve/controller includes integral power backup. In the event of power failure, the
control shifts into a power-saving mode. The control stops monitoring water usage, and the
display and motor shut down, but it continues to keep track of the time and day for a minimum of
48 hours.
The system configuration settings are stored in a non-volatile memory and are stored indefinitely
with or without line power. The day of the week and time of day display flashes when there has
been a power failure.
If power fails while the unit is in a flush cycle, the control will save the current valve position
before it shuts down. When power is restored, the control will resume the cycle from the point
where power failed. Note that if power fails during a flush cycle, the valve will remain in its current
position until power is restored. The drain line plumbing configuration should include all required
safety components to prevent overflows resulting from a power failure during backwash.
The control will not start a new flush cycle without power. If the valve misses a scheduled flush
cycle due to a power failure, it will queue one for the next day. Once power is restored, the
control will initiate a cycle the next time that the time of day equals the programmed cycle time.
MAINTENANCE & TROUBLESHOOTING
WARNING: The controller MUST be depressurized before removing any quick connection clips
for servicing.
