10.1. Error detection

A
Note
It can take up to 30 seconds before an error can be detected and displayed.
A
Mandatory
All the errors must be displayed on each controller before they can be corrected.
• If an error is detected, the status LED light will be red.
• During an error condition, the unit continues to monitor flow and update the remaining capacity.
Once an error condition is corrected, the unit returns to the operating status it was in prior to the
error, and regeneration resumes according to normal programming.
• If an error is cleared by reprogramming the unit in the Master Programming Mode, the volume
remaining may be reset to the full unit capacity (as though it had just regenerated).
• If an error is present, a regeneration can only occur manually by pressing and holding the
Regeneration button for 5 seconds.
• If the unit was in regeneration when the error occurred, it completes the regeneration cycle and
goes to service.
• When the problem is corrected, and the error no longer displays (it may take several seconds for
the unit to stop displaying the error message), the unit returns to normal operation. The status
LED light is not longer Red, and turns Green if the unit is regenerating, or Blue if the unit is in
service.
