Cam Sense
Error
The valve drive
took longer than
6 minutes to
advance to the
next regeneration
position
Unplug the unit and examine the powerhead. Verify that all cam switches are
connected to the circuit board and functioning properly. Verify that the motor and
drive train components are in good condition and assembled properly. Check the
valve and verify that the piston travels freely. Replace/reassemble the various
components as necessary.
Plug the unit back in and observe its behavior. The unit should cycle to the next
valve position and stop. If the error re-occurs, unplug the unit and contact
technical support.

Cycle Step
Error
The control
experienced an
unexpected
cycle input
Unplug the unit and examine the powerhead. Verify that all cam switches are
connected to the circuit board and functioning properly. Enter Master Programming
mode and verify that the valve type and system type are set correctly with regard
to the unit itself.
Step the unit through a manual regeneration and verify that it functions correctly.
If the error re-occurs unplug the unit and contact technical support.

Regen
Failure
The system has
not regenerated
for more than 99
days (or 7 days if
the Control Type
has been set to
Day-of- Week)
Perform a Manual Regeneration to reset the error code. If the system is metered,
verify that it is measuring flow by running service water and watching for the flow
indicator on the display. If the unit does not measure flow, verify that the meter
cable is connected properly and that the meter is functioning properly.
Enter a Master Programming Mode and verify that the unit is configured properly.
As appropriate for the valve configuration, check that the correct system capacity
has been selected, that the day override is set properly, and that meter is identified
correctly. If the unit is configured as a Day-of-Week system, verify that at least one
day is set ON. Correct the settings as necessary.
