Calibration (LMLS-400 Only)
CALIBRATION (LMLS-400 ONLY)
Calibration establishes a relationship between the
workplane illuminance and the light level measured
by the sensor. This can be done Automatically or
Manually.
Automatic Calibration
Automatic Calibration can be started by the
LMCT-100, or by pressing and holding the user
pushbutton located in the sensor head.
1. Complete all wiring and turn power on to the
connected room controller.
2. Press and hold the user button for at least 2
seconds then release, or activate automatic
calibration from the LMCT-100.
3. Blue LED will start fl ashing once every 4 sec.
4. Daylighting controlled loads will automatically
turn ON for 2 minutes to allow controlled lamps
to warm up and reach a stable full output.
5. Remove any objects that may affect the LMLS-
400 light level reading (ladder or temporary
objects).
6. Lights will cycle eight times for automatic
setpoint selection.
7. The photosensor is in Test Mode when the blue
LED starts fl ashing once per second. For the next
5 minutes the sensor will be in Test Mode.
8. Verify the setpoints automatically selected by the
photo sensor with the LMCT-100. If the automatic
selected setpoints are not acceptable, proceed to
manual calibration.
