Troubleshooting
Communication Error
If a communication error is detected,
cErr
displays. It may take several minutes for all of the units in a system to
display the error message.
— 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.
— When the communication problem is corrected and the error no longer displays (it may take several
minutes 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 remaining
volume. 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).
NOTE:
System 4 units retain their normal display and do not display
cErr
.
