Troubleshooting
Detected Errors
NOTE: It can take up to 30 seconds for an error to be detected and displayed. All errors on each timer in
the system must be displayed before the errors can be corrected.
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.
Cause Correction
A. One or more units have a missing or bad
communication cable.
A. Connect the communication cables and/or replace.
B. One or more units has a communication cable
plugged into the wrong receptacle.
B. Connect the communication cable as shown in the
wiring diagrams.
C. One or more units is not powered. C. Power all units.
Programming Errors
During the error condition the control continues to monitor the flow meter and update the remaining capacity.
Once the error condition is corrected all units return to the operating status they were in prior to the error and
regeneration is queued according to the normal system operation. If reprogramming the unit in the Master
Programming Mode clears the error, the volume remaining may be reset to the full unit capacity (i.e. as though it
were just regenerated).
1. All units in standby go In Service.
2. Any unit in regeneration when the error occurs completes regeneration and goes to In Service.
3. No units are allowed to start a regeneration cycle while the error condition exists.
When the problem 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.
Programming Errors Detected:
— Duplicate unit addresses or numbers
— Size of system (ex: if sized for a 4 units, and only have 2 units)
— Display format mismatches
Solution:
— Program the units correctly in the Master Programming Mode.
NOTE: If these errors are detected, numbers 1 through 3 become true, and the main screen (time of day) will
alternate with an error screen.
