Error Codes
NOTE: Error codes appear on the In Service display.
Error Code Error Type Cause Reset and Recovery
0 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.
1 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.
2 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.
3 Memory
Error
Control board memory failure 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 reoccurs, unplug the unit and contact technical
support.
UD Upper Drive
Sync
Power failure/Programming has
been changed.
Valve should recover automatically. If valve fails to come out of “UD”, check
that the motor is cycling the gears. If not, you may have a jammed piston or
a device motor that needs to be replaced. If the motor is cycling the gears,
drain the super capacitor. Unplug the unit and press the rest button on the
circuit board. Plug the unit back in and the display should be restored. The
unit is ready for operation or programming.

Power Failure Check that the transformer is putting out 24 volts AC. If the transformer is
functioning properly, drain the super capacitor on the circuit board. Unplug
the unit and press the reset button on the circuit board. Plug the unit back in
and the display should be restored.
