Dip Switch Settings
Dip switches on the rear panel of the Light Sensor Controller provide for
additional configuration options including deadband sensitivity, delay time, and
the ability to restore the sensor to its factory defaults.
Dip Switch 1
Dip switch position 1 determines whether the sensor will use a Dimming
operation (Off) or a Switched operation (On). The default setting is Dimming
operation. Reference
Dimming Photo Sensor Operation or Switched Photo
Sensor Operation on page 12 .
Dip Switch 2
Dip switch 2 uses the “Custom Config” setting.This is reserved for future use.
This switch must remain “Off.”
Dip Switch 3&4
Dip switches 3 & 4 set the “Delay Time”. Supported times are in minutes.
• 5 min = Switches 3 and 4 are “Off” (default)
• 15 min = Switches 3 is “Off” and 4 is “On”
• 30 min = Switches 3 is “On” and 4 is “Off”
• 60 min = Switches 3 and 4 are “On”
Dip Switch 5&6
Dip switches 5 & 6 set the deadband sensitivity, which corresponds to 10%,
20%, 35%, and 50% as a percentage of the Target Lux. The low measured
light threshold is Target - (Target x Deadband%) / 100.
See “Record Target” on
page 11. The high measured light threshold is Target +
(Target x Deadband%) / 100.
• 10% = Switches 5 and 6 are “Off”
• 20% = Switch 5 is “Off” and 6 is “On”
• 35% = Switch 5 is “On” and 6 is “Off”
• 50% = Switches 5 and 6 are “On”
Dip Switch 7
Dip switch 7 is not used in this product.
Dip Switch 8
Dip switch 8 provides a “restore defaults at boot” function. The factory defaults
are restored by setting this dip switch (“On”), and cycling power to the sensor.
