ADJUSTMENT
All adjustments are made on the control module. Please see the COVERAGE
GUIDE for instructions on accessing the adjustment controls and setting the
adjustable features.
PASSIVE INFRARED SENSING IN WAREHOUSES
Warehouses can have ambient temperature variations that may affect sensor
detection and coverage areas. When specifiying high mount sensors, take
into account the temperature at the coverage location. High temperatures at
the covered area (above 89-92°F) reduce the detection zone of the sensor.
Consider adding more sensors if the ambient temperatures are expected to
be high. Additionally, high floor level temperature may require larger
movement for detection. In some cases, sensors mounted above 40' may only
detect large heat signatures such as forklift trucks.
TROUBLESHOOTING
During the sensor warm-up period, which can last up to a minute after power
is applied to the Control Module (or after a power outage of 5 minutes or
more), the load can be either on or off, depending on the status of the relay
before the sensor was powered down. After warm-up, the sensor will open or
close the relay to correspond to the occupancy status of the room.
To quickly test the unit, turn the time delay to minimum. Wait for the warm-
up period to end. Move out of the sensor's view. Lights should turn off after
30 seconds. Move into the sensor's view. The sensor's Red LED should blink
and the lights should turn on.
Control Module Connector Pins
The connector pins supply power and relay operation signals between the
modules. Always check to make sure that the modules are properly seated
and securely snapped together. If the pins are not aligned correctly and then
excessive force is used to snap the modules together, a pin can bend causing
the sensor to malfunction. Gently bend any bent pin back into proper
alignment before reconnecting the modules. Re-test to see if the problem is
solved. If the problem persists, go on to the next troubleshooting step.
Red LED on Control Module does not blink:
1. Remove Control Module and see Control Module Connector Pins, on the
previous page.
2. Check sensor wire connections. Verify the neutral wire is tightly secured.
Red LED blinks but lights do not turn on:
1. Remove Control Module and see Control Module Connector Pins, on the
previous page.
2. Check all sensor wire connections. Verify the load wire is tightly secured.
3. Check power connections to the light fixture.
4. If the control module has the light level feature (model number ends in
"D"), cover the sensor lens to simulate darkness. If the light turns on, the
light level setting needs to be adjusted. If set for minimum, more than 10fc
of ambient light causes the lights to be held off. See ADJUSTMENT: Light
Level Feature in the COVERAGE GUIDE.
Lights will not turn off:
1. If there is no motion in the sensor's view but the red LED blinks, look for
an air blower nearby. Turn off the blower, or move the sensor.
2. Remove Control Module and see Control Module Connector Pins, on the
previous page. Before reconnecting the module, go to step 3.
3. Verify time delay. The time delay can be set from 30 seconds to 30
minutes. Ensure that the time delay is set to the desired delay and that
there is no movement within the sensor's view for that time period.
4. Check sensor wire connections. Verify load and neutral wires are secure.
