TROUBLESHOOTING
CAUTION
TURN POWER OFF AT THE CIRCUIT BREAKER
BEFORE WORKING WITH OR NEAR HIGH VOLTAGE.
Lights do not turn on with occupancy, and the following condition exists:
• PIR Activity LED does not flash:
NOTE: When power is initially applied to the sensor, there is a warm-
up period of up to 30 seconds before the LED is active.
1. Check that the circuit breaker has been turned back on.
2. Make sure that the PIR Sensitivity is set for Max/Smartset (DIP switch 7 on).
3. Check all sensor and power pack wire connections.
4. Check for 24V input to the sensor.
-
If 24V is present, replace the sensor.
-
If 24V is not present, check that high voltage is present to power pack.
If it is, replace power pack.
• PIR Activity LED flashes:
1. If the sensor’s Light Level feature has been turned on, 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 and PIR Activity LED (see diagram) with your
hand to see if the lights turn on. If the lights turn on, the Light Level setting
was keeping the lights off (see, “Sensor Adjustment” for readjustment).
2. Check all sensor and power pack wire connections.
3. Check for 24VDC at the power pack’s blue wire connection to
sensor while sensor is activated. If there is no voltage, replace
the sensor. If there is voltage, replace the power pack.
