1. Set the Time Delay to minimum, 15 seconds.

2. Set the Light Level trimpot to minimum, fully counterclockwise.

3. Be still and allow the lights to turn off.

4. Move a hand in front of sensor every 10 seconds (to keep sensor activated), and without blocking any light from reaching the

sensor, in small increments, turn Light Level adjustment toward maximum, waiting at least 5 seconds between increments, until

the lights turn on. Then turn it back slightly. At this setting the lights will not turn on with occupancy if the ambient light is above the

current level.

5. Set the desired Time Delay.

6. Readjust the angle of the sensor if necessary.

Lights do not turn on with occupancy, and the following condition exists:

LED does not flash:

When power is initially applied to the sensor, there is a warm-up period of up to 60 seconds before the LED is active.

1. Check that the circuit breaker has been turned back on.

2. Check the Sensitivity settings. Increase (clockwise) as needed.

3. Check all sensor and power pack wire connections.

4. Check for 24VDC at sensor (violet and green or gray wires).

• If 24VDC is present, replace the sensor.

• If 24VDC is not present, check that high voltage is present to power pack. If it is present, replace power pack.

LED does flash:

1. The Light Level setting or the Sensitivity may be set too low.

2. If the sensor's Light Level feature has been utilized, the lights connected to the Light Level Output might be held off because of the

level of ambient light in the controlled area.

• To test whether the Light Level adjustment is the problem, cover the PIR lens with your hand for 5 seconds to see if the lights turn on,

or turn the Light Level adjustment toward maximum (clockwise). If the lights turn on, the Light Level setting was keeping the lights off.

• Increase the Light Level setting slightly or follow the procedures under "Sensor Adjustment" to adjust the Light Level setting.

• The Sensitivity adjustment should be set to maximum, unless a decrease is made due to an "Unwanted Sensor Activations"

adjustment.

3. Check all sensor and power pack wire connections.

4. Check for 24VDC at the power pack's blue wire connection to sensor while someone moves in front of sensor to activate the LED.

If there is no voltage, replace the sensor. If there is voltage, replace the power pack.

Lights do not turn off automatically:

1. The sensor may be experiencing activations from outside the controlled area or from some type of interference (see "Unwanted

Sensor Activations" next page).

2. Check all sensor and power pack wire connections.

3. Disconnect power pack's blue wire:

• If the lights do not turn off, replace power pack. Reconnect

blue wire.

• If the lights turn off, the problem may be in the sensor–to check:

4. Reconnect the blue wire.

5. Turn sensitivity and time delay to minimum and allow the

sensor to time out.

• If the lights turn off, the sensor is working properly (see number

1., above, and "Sensor Adjustment" for readjustment of sensor).

Unwanted Sensor Activations (LED flashes):

Possible causes

1. Improper sensor location or angle adjustment causing

detection outside of desired coverage area.

2. Sensitivity set too high.

3. Sensor located too close to HVAC or VAV vents with heavy air

flow.

Possible solutions

1. Mask the lens to reduce PIR coverage (see "Masking the

lens", under "Coverage Patterns").

2. Reduce the sensitivity (counterclockwise) as needed (see

"Sensor Adjustment").

3. Adjust the sensor angle (see "Sensor Adjustment").

4. Relocate the sensor.

Override:

To override all sensor functions, set DIP switch #5 to on. The red

LED will come on and stay on for the duration of the override.
