Control Operation (Cont’d.)
Control Operation During A Power Failure
During a power failure all control displays will be turned off and regeneration cycles delayed. The control will otherwise
continue to operate normally until line power is restored or battery backup power is lost.
1. If battery backup power is never lost during a power outage, the control will continue to operate normally, without
the loss of data, until line power is restored.
2. If battery backup power is lost during a power outage, the control will store the current Time Of Day, Volume
Remaining, Regeneration Cycle Status, and various diagnostic displays. These stored displays will then be used
upon line power restoration until updated ones are created. To indicate this type of failure, the control will flash the
current Time Of Day Display to indicate that this display and the Volume Remaining Display may not be correct.
Control Operation During Regeneration
In regeneration the control will display what regeneration step number the valve is advancing to, or has reached, and
the time remaining in that step. Once all regeneration cycle steps have been completed the valve will return to service
and resume normal operation.
1. First the Regeneration Arrow turns on. Then the display below is viewed to indicate that the valve is advancing to
the first regeneration cycle step.
2. When the first cycle step is reached, the display becomes as shown below, A red LED will also turn on to indicate
the current regeneration cycle step.
3. Pushing the Extra Cycle Button during a regeneration cycle will immediately advance the valve to the next cycle
step position and resume normal step timing.
4. Pushing the Up or Down Set Button during a regeneration cycle will adjust the time remaining in a regeneration
cycle step. Actual Regeneration Cycle Step programming will not be changed.
