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
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 no longer Red, and turns Green if the unit is regenerating, or Blue if the
unit is in service.
