Calibration (LMLS-600 Only)
PLEASE NOTE
It is critical that, during the Automatic Calibration
process, the area under the sensor, as well as the
skylight area, remain free of any obstructions, and
that no changes occur (including human foot traffi c)
within the cone-of-view of the closed loop sensor.
Please clear the area before starting the Automatic
Calibration, and wait for the calibration completion
(when the blue LED stops fl ashing once every 4
seconds) before reentering the area.
The Calibration process consists of:
- Pausing for 15 seconds to allow the user to vacate
the area under the sensor.
- Turning off all confi gured loads, for about 10
seconds, to compute an initial daylight ratio.
- Warming up the controlled loads, at maximum
level, until they reach full output (typically, this
requires several minutes).
- Switching or Fading the level of the controlled
loads from maximum to minimum level very slowly
(over approximately two minutes) while observing
both sensors, to determine the ballast curve.
- Turning the controlled loads off completely, and
observing both sensors for several seconds, to
calculate daylight ratios..
- Validating the data collected, and marking
the sensor as calibrated (and active) if a good
calibration has been established. If the calibration
should fail, the LEDs will revert to showing an
“Awaiting Calibration” state and the process must
be repeated.
