TROUBLESHOOTING
Detected Errors
If a communication error is detected, an Error Screen will alternate with the main (time of day) screen every few seconds.
• All units In Service remain in the In Service position.
• All units in Standby go to In Service.
• Any unit in Regeneration when the error occurs completes Regeneration and goes to In Service.
• No units are allowed to start a Regeneration Cycle while the error condition exists, unless they are manually forced
into Regeneration.
• When an error is corrected and the error no longer displays (it may take several seconds for all of the units in a
system to stop displaying the error message), the system returns to normal operation.
NOTE: During the error condition the control continues to monitor the flow meter and update the volume
remaining. Once the error condition is corrected all units return to the operating status they were in prior to
the error. Regeneration queue is rebuilt according to the normal system operation. Or, if more than one unit
has been queued for regeneration, then the queue is rebuilt according to which one communicates first.
