Handling Faults
DP Fault
The AMCFlushing Controller can detect and respond to filter clogs. This is done by monitoring the
status of the D.P. signal. By the end of the flush cycle the controller monitors the DP signal for 30
seconds, if during this period the DP-signal remains high the controller starts another flushing cycle.
After performing between 1 to 9 cycles (depend on the controller’s configuration), the controller enters
to DP fault. This indicates a clogged filter or a faulty DP sensor.
Check the filter and manually clean it.
Check the sensor and if necessary replace it and then press and hold the Manual key for 5 seconds to
exit the fault and resume operation.
Low Battery
When the controller displays the Low Battery Icon, stop its operation and replace the battery with a
new one (see "Installing and Replacing Batteries (DC Models)" on page17).
