4 Installing the RF Sen-
sor
This section details how to install the various
models of RF Sensors, including mounting and
placement, activation, and clean switch and
defrost termination wiring.
4.1. Placement of RF Sensors
Ideally, all RF Sensor models, including
product simulators, should be located some-
where within a refrigerated case where a clear
line of sight exists between itself and an RF
Receiver. In any case, the signal path between
the RF Sensor and the RF Receiver should
not be blocked by large amounts of product
or thick metal case walls.
4.1.1. RF (Short-Range) Ambient
Sensor
The RF Ambient Sensor kit includes a plas-
tic mounting clip. This clip may be fastened any-
where on a shelf or the side of a refrigerated
case. After mounting the clip, the sensor may be
snapped on to the mounting clip.
4.1.2. RF Long-Range Transmitter
The RF Long-Range Sensor transmitter
enclosure is equipped with two endcaps, each of
which has a mounting hole. Screw the sensor
enclosure to a shelf or the side of a case using
the endcap mounting holes.
4.1.3. RF Product Simulator
The RF Product Simulator kit includes a
plastic mounting clip. This clip may be fastened
anywhere on a shelf or the side of a refrigerated
case. After mounting the clip, the sensor may be
snapped on to the mounting clip.
4.2. Activation
All RF Sensors will be shipped with the
power OFF (a.k.a. Sleep mode) to save battery
life. The sensors must be activated before they
will start transmitting. To activate the sensor,
locate the Service button and press for one sec-
ond (see Figure 4-1 for the service pin loca-
tions).
When activated, the sensor LED will stay
ON for one second to indicate the sensor is exit-
ing Sleep mode and beginning operation.
4.2.1. Verifying Active State
When an RF Sensor is active, you can verify
its active state by momentarily pressing the Ser-
vice button and then releasing. If active, the sta-
tus LED will flash once. If the light does not
come on, it is either in Sleep mode or has a dead
or missing battery.
4.3. Clean Switch and Defrost
Termination Wiring
Sensor models with internal clean switches
do not require any extra wiring to enable clean
switch functionality; the button on the sensor
enclosure acts as a clean switch.
