TROUBLESHOOTING
Lights do not switch or dim when desired, under daylight control
• Use the pushbutton on the photosensor face to manually test load control (see SENSOR PUSHBUTTONS on page 3). If the lights
do not switch ON and OFF, check Zone Settings to rebind the loads. If the lights do switch ON and OFF, use the Zone Settings
screen to verify that the ON and OFF setpoints are correct (if Switching / Bi-Level / Tri-Level), or if dimmed, dimming setpoint is
correct. Place the photosensor in Test Mode to quickly verify daylighting operation; shine a flashlight into the sensor, or cover the
sensor, to simulate major light level changes.
• The calibration may not be completed. To check calibration status, check the last screen in the Advanced Settings menu. If the
electric light (EL) value is 0, perform the calibration process.
Red LED is ON, not flashing
• There is an internal failure in the LMLS-500 sensor. Try unplugging the sensor from the DLM network, then plug it back in and wait
for ten seconds. If the red LED comes back on, and is not flashing, the sensor is defective and must be replaced.
Red LED is flashing ON for three seconds, OFF for one second (repeating)
• The LMLS sensor is in
Control Mode <Disable>
. Use the LMCT-100 to change the Control Mode parameter to
<Normal>
to
resume daylighting operation.
Blue LED is flashing
• If the blink is slow (one flash every four seconds), the photosensor is in an override condition, either due to an override from a wall
switch or due to manual commissioning operation. If the latter, complete the commissioning operation first; otherwise, use a wall
switch to turn off the controlled loads to terminate the override.
• If the blink is faster (one flash every second), the photosensor is in Test Mode or Demo Mode. Test Mode will cancel automatically
after five minutes. Alternatively, Test Mode or Demo Mode can be turned off by selecting the Control Mode menu from the LMLS-
500 main screen in the LMCT-100.
Reset to Factory Defaults
• If the photosensor has been moved from a different location, or its internal parameters are unknown and an LMCT-100 is not
immediately available, it can be reset to factory defaults by pressing and holding the CONFIG button for 20 seconds (see SENSOR
PUSHBUTTONS on page 3).
