Installation, Operation & Maintenance of the Wireless Sensing Family

With a GPRS unit, the test sequence is prolonged–until the GPRS
modem connects.
Once the USG connects to the communication server, the Green LED
lights solid. If it blinks-it indicates that the USG battery is not fully
charged – per Table 7.
If other LED indicators are showing, refer to chapter
5 for troubleshooting
procedures.
3.3.6
Resident Sensor activation
Resident Sensors are usually deployed when:
•
Stationary environmental monitoring is required.
•
If the area cannot be covered with a single Gateway, then Resident
Sensors can be used as battery operated repeaters / range extenders.
To operate (turn on) the Resident Sensor See
remove the batteries compartment cover (5)
Insert two AAA batteries.
Activate the RS by pushing the “activation PB” (6)
3.3.7
Placement of wireless U-sensors
Locating the wireless sensors in the following places will reduce the system
performance (decrease transmission range).
o
Near a PC.
o
Near electric motors (like industrial fans, elevators, etc.)
o
Industrial frequency controllers.
o
Placing the antenna directly on a metal surface.
The CartaSense Wireless Solution is optimized by placing one sensor per each
monitored pallet.
Placing the wireless sensor in the pallet is straight forward and easy:
o
Power on and put the wireless sensor anywhere in or on the
pallet.
Assembly and operation stages are successful when power is on and a green led on the
USG starts to blink within 5 minutes from power up.
To check whether the resident Sensor is connected to a U-Sensor Gateway, push the
operation button. The red LED will blink consecutively if the sensor is connected
The U-sensor a
ntenna should be stretched and if possible the antenna wire should
extend outside the package.
