3. Navigate to the CAL menu in the WH and key in the following commands. Make sure that
each command is acknowledged before moving to the next one.
o Remove previous calibration using RESET CAL.
o Where applicable make sure the valve is completely open and set the open angle using
SET OPEN option.
o Where applicable make sure the valve is completely closed and set the closed angle
using SET CLOSE option.
o If required set the custom angle using SET CUSTOM option.
o Apply the new settings using APPLY option.
The order of calibration SET OPEN before SET CLOSED or vice versa is not important.
Perform the above steps at your convenience.
The WD can also be run from default values or partial calibration. This is pertinent when an
installation is performed on a “hot line”. A complete calibration process can be completed at a
later time (after the valve has changed its state).
When completing a partial calibration, do not send RESET CAL, otherwise the previous
calibrated angle will be erased.
3 WD Troubleshooting and maintenance
3.1.1 Device Does not Power Up
1. Verify that the device has an installed battery pack.
2. Using the WH, send a Join/Join All command to the WDs from a distance of 10 cm to 1 m.
Sending a command when the WH is too close (< 10 cm) to the WD will saturate the WD
receivers and the transaction will be aborted. Keep the WH between 10 cm and 1 m.
3. When a successful transaction occurs, the LEDs flash in sequence for a few seconds. If
necessary remove the WD cover to see the LEDs.
