Troubleshooting
Error Codes and Troubleshooting
Detected Errors
If a communication error is detected, an Error Screen will appear.
• 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 remain-
ing. 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 sys-
tem operation. Or, if more than one unit has been queued
for regeneration, then the queue is rebuilt according to
which one communicates first.
