TROUBLESHOOTING
• Check that wiring connections are correct and secure.
• Make sure that the line voltage is +/- 10% of rating.
Lights do not turn off after the time delay elapses, and…
… the red LED does not flash (does not sense motion)—possible sensor or power pack problem:
—Set DIP switches to Output Disable, or disconnect the blue wire to the sensor.
• If lights go out—possible sensor problem (Call Tech Support).
• If lights do not go out—check wiring, if OK—possible power pack problem (Call Tech Support).
… the red LED flashes (senses motion):
—Set DIP switches to Output Disable, or disconnect the blue wire to the sensor.
• If the lights do not go out—check wiring, if OK—possible power pack problem
(Call Tech Support).
• If the lights go out—reset the DIP switch to previous settings, or reconnect the blue wire. Note
the sensitivity and time delay settings, then lower the sensitivity and time delay adjustment to
minimum.
a) If the lights go out after the set time delay period—the sensor may have been adjusted too
high, so that vibration, air movement or other minor motion was activating it. Adjust the
sensitivity down from its previous setting to a level needed for normal operation, and reset
the time delay.
b) If the lights still do not go out—possible sensor problem (Call Tech Support).
