Solutions
Check the diagnostic codes on the LED Status window
(using magnet) on the monitor top to verify the IP
address is available. If it does not display initially,
activate the LED
Status window again after a minute or
two. Activating the LED Status will reset the modem,
which typically enables it to reconnect to the monitor. If
it still does not display, disconnect the battery pack from
the monitor for at least 1 minute and then reconnect the
battery pack. Once the LED is no longer illuminating,
reactivate the diagnostic codes to verify whether the IP
address is now available.
Relocate the antenna (consider a pedestal mount if
installed outside the manhole)
Reposition the antenna in the correct position of
horizontal and with “This Side Up’ facing upward.
Replace the antenna.
Replace the monitor battery pack ( when applicable ) if it
is reading below the minimum voltage requirement.
Try connecting to other wireless units in the same area
(other wireless monitor sites). If all connections fail for
similar IP addresses and/or none of the wireless
connections are successful, there may be a wireless
network outage in your area. Contact your regional ADS
representative for them to investigate a possible outage.
Delete any leading zeros included before or within the IP
address.
Replace SIM card in the GL monitor. (Does not apply to
4VZ.)
( applies only if the software provides a “ Getting Monitor
Attention ” message while attempting to communicate )
Try to communicate with the monitor through a serial
(
direct ) connection. If direct communication fails,
remove the monitor from the hazardous area (at least 20
feet away from the manhole), disconnect the battery
pack, wait at least 1 minute, reconnect the battery pack,
and then attempt to communicate. If the monitor still will
not communicate, replace the 3.3-volt yellow fuse on the
regulator.
Replace the monitor.
