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.
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.
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.
Perform a Master Reset and reconfigure the system via Master
Programming Mode. After reconfiguring the system, step the valve
through a manual regeneration. If the error re-occurs unplug the
unit and contact technical support.
Valve will automatically recover.
