Wiring (Sensor): With controller unpowered, carefully
route the Occupancy sensor cable to the controller. Take
caution to route the cable away from sharp edges. Ensure
the terminal screws on the controller are backed all the way
out. Insert the leads of the sensor wire into “Occupancy”
location on the controller, see chart below for sequence.
Tighten the terminal screws to 3-5 in.-lb. Carefully tug the
leads to ensure they are secure. See the following figure.
Wiring (LED Driver): The S3C requires an LED driver that
supports a 0 to 10VDC signal. The controller will send the
LED driver a signal based on the light level configuration of
the occupancy sensor. With controller unpowered, carefully
route the LED driver cable to the controller. Take caution to
route the cable away from sharp edges. Ensure the terminal
screws on the controller are backed all the way out. Insert
the leads of the sensor wire into “Gnd” and “10V” location
5.4.7 CASE SURFACE TEMPERATURE
SENSOR
5.4.7.1 MOUNTING
The case surface temperature sensor is required when using
dew point control option for anti-sweat heaters. The sensor
must be mounted on the door frame to detect surface
temperatures. Follow case OEM instructions for exact
mounting location. Note: Use caution when fastening
to the door frame to ensure internal case wiring is
not damaged.
5.4.7.2 WIRING
With controller unpowered, carefully route the blue case
surface sensor leads to the controller. Take caution to
route the leads away from sharp edges and pinch points.
Ensure the terminal screws on the controller are backed
all the way out. Insert the leads of the sensor wire into
“Auxiliary” location on the controller. Tighten the terminal
screws to 3-5 in.-lb. Carefully tug the leads to ensure they
are secure. See the following figure. Note: Leads are not
polarized and may be installed in either location. The
“Auxiliary” temperature input can also be used for the CT.
The controller will need to be configured on which sensor is
used. See Section 12.3 for configuration of this input.
Note: If the Defrost CT is used, fixed pulse anti-sweat
control must be used instead of dew point control.
5.4.8 OCCUPANCY SENSOR
5.4.8.1 MOUNTING
The Occupancy sensor is required when a case lighting
schedule is not defined in the controller. The sensor must
be mounted on the top and centered of the case. The range
of the sensor is shown in the figure below. Note: Use
caution when fastening to the top of the case to
ensure internal case wiring is not damaged.
