AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate has a self-diagnostic function for the
electrical system (except input power). The face plate
monitors the electronic components and circuits for
correct operation. If a malfunction
occurs, an error code appears in the
face plate display .
The chart below shows the error codes that could
appear, and the possible defects for each code.
While an error code appears in the display, all face
plate buttons are inoperable except the SET button.
The SET button remains operational so the service
person can make the MANUAL ADVANCE DIAG-
NOSTICS to further isolate the defect.

E— 3, E— 4
wiring harness or connection to switch / position switch / motor inoperative / valve defect causing
high torque E— 3, E— 4 high torque
PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct de-
fect 3. Plug-in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.
FACE PLATE REPLACEMENT: Be sure the valve is in service position (observe valve cycle indicator. . . see
below) when replacingthe face plate.
If, after installing and programming the replacement face place, the valve is not in service position, do the fol-
lowing to assure correct cycle orientation, or timing, between the face plate and valve.
Use the MANUAL ADVANCE procedures, below. With the RECHARGE NOW button, advance through the
recharge cycles until the valve stops in service position, and RECHARGE no longer flashes in the timer.
NOTE: The valve motor may automatically drive through several valve positions while searching for service.
