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
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.
