3.1.2 Device Is not Presented in the WMS
1. Verify that the WMS is active.
2. Verify that at least one WG is online on the WMS bottom bar (see WMS specific IOM for
more details).
3. Verify that the WG is connected to a wireless network.
4. Verify that the WD and WG are in the same network.
5. If the Tx LED does not flash during valve movement or LED flashing intervals:
o Verify that the WH is in the same wireless network as the WG and then shut down the
WD and join it again to the active wireless.
o The WD has not completed handshake with the WG. Wait up to 2 minutes for the
action to be completed or reset the WG.
o The WD is not in the same Connectivity Group as the WG (e.g., 255) and therefore
cannot perform a handshake with the WG. Using the WH, open a session and set the
Connectivity Group of the WD to 0. Alternatively, using the WH, open a session, read
the Connectivity Group on the WD, and set it to the same Connectivity Group as that of
the WG (or the opposite).
3.1.3 Device Presents Invalid Angle Readings
1. If valve angle readings are erratic or non-continuous (from 0 to -10 and then 110 to 50)
try to recalibrate open and close points.
2. Check if stem is in the valid motion zone.
If the valve has not been properly installed, the stem might be outside the valid range of the
motion zone indications resulting in this inconsistent angle report.
3.1.4 Device Performs Continuous Resets (LEDs Constantly Flashing in
Sequence)
1. The WD battery pack usage may be momentarily overextended. Allow it to refresh for up to
4 minutes before continuing.
2. The fuse on the battery pack is blown. Verify and replace the battery pack.
The WD LEDs may continue to flash even if the fuse is blow for a long period of time up to
many days.
3. The WD battery may be run down. In such a case, replace the battery.
