5.3 Battery Considerations
As shipped from the factory, the sensor will have two battery cells installed. There will be a small battery insulator tab installed over the
positive terminal of one cell, to inactivate the sensor electronics (see Figure 6 1). The following are suggested policies:
• Do not remove the tab until the unit is ready for use, as battery life will be considerably shortened. The unit will transmit
frequently, trying to establish communication with a node. This node establishment will not succeed, if the network has not yet
been provisioned for that sensor.
• Do not remove the tab and provision the unit until the unit is in its intended location, as it will try to establish links with what-
ever AP's are nearby. This will cause unnecessary transmissions through the network to occur, wasting battery power and
using bandwidth.
• When a sensor is removed from service, and is to be stored, it is recommended that the insulating tab be installed, or the bat-
teries removed, so as to preserve battery life and avoid unnecessary data transmissions.
Refer to Section 6 for battery replacement procedures.
Definition
All channels are out of service.
Diagnostics detected defect
with analog-to-digital converter
Battery voltage critically low,
below 4.3 Vdc
Startup diagnostics detected

The input pressure has crossed
the sensor maxumum limit as
stored in the characterization
data.
Note: this error will clear when
the input pressure is measured
as 1 % or more below the maxi-
mum limit.
ISSUE 1
What to do
Insure sensor has been properly provisioned with the
WDM UI.Restore mode to Auto in
UI.
Perform cold restart per WPS Series Professional In-
stall Guide. If condition persists, measurement board
has failed, sensor must be replaced.
Replace batteries as soon as possible. See Section 6.

Perform cold restart per WPS Series Professional In-
stall Guide. If condition persists, measurement board
has failed, sensor must be replaced.
Crosscheck input pressure with other means, if actual
pressure is less than the sensor maximum limit, the
pressure sensor within the unit has probably failed,
sensor must be replaced.
