10 Troubleshooting
10.1 Error detection
Info
It can take up to 30 seconds before an error can be detected and displayed.
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
• 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 no longer Red, and turns Green if the
unit is regenerating, or Blue if the unit is in service.
