CONFIGURATION SETTINGS
AMBIENT LIGHT OVERRIDE (PHOTOCELL) OPERATION
During periods of occupancy, sensors with an integrated photocell (models SWX-21x-2,
SWX-23x-2) will turn lights on/off depending on the amount of ambient light detected.
This operation makes them ideal for lighting in daylight zones (i.e. near windows). Lights
will turn off when the measured light level is high enough for 5 min. such that turning the
lights off will not drop the level below the selected setpoint. During this 5 min. transition
PHOTOCELL SETPOINT
The minimum overall light level that is to be maintained in a space by the sensor is
referred to as the "setpoint". This value is user selectable or can be chosen by the Auto-
Setpoint function that is built into the sensor.
SETPOINT CONFIGURATION
1. Read through the below setpoint values list and note the number of the desired
setpoint (e.g., default is 7 = 25 fc).
2. Press and release the unit's pushbutton 4 times, then wait 2 seconds. The White LED
will blink back the number of the current setting.*
3. At any time after blinking starts, enter number of new setting (from Setpoint Value
Table).
4. New setting is saved after White LED blinks new setting back 3 times. If Blue LED
double flashes at any time, an error condition exists and process must be repeated.

time the LED will blink blue at 0.5 second intervals. After lights are turned off, the
sensor's LED double blinks blue every 15 seconds as an indication that sufficient ambient
light is the reason the lights are being held off. If the ambient light level falls below the
setpoint for more than 30 seconds, lights will switch back on. During this transition time
the LED also will blink blue at 0.5 second intervals.
*AUTO-SETPOINT SELECTION DETAILS
A Once setting 2 "Run Auto-Setpoint" has been selected (by following above steps 1-4),
the sensor's LED will alternate blue and white for 30 seconds. During this time user
should move away from sensor.
B Lights will then be cycled in order for sensor to calculate the controlled (artificial) light
level. This is done by subtracting the light level with the lights off (relay open) from the
light level with the lights on (relay closed).
C A setpoint will then be chosen using the following conditions:
If controlled level is less than 3 fc, the application is considered open loop and
à Ã
the setpoint will be set to 50% of the measured level with the relay closed (plus a
margin to prevent cycling). Setting will be between 0.5 fc and 44 fc.
If controlled level is between 3 and 50 fc, setpoint will be set to that level times
à Ã
1.25.
If controlled level is greater than 50 fc the setpoint will be set to 50 fc.
à Ã
D Unit will immediately start operating with new setpoint (i.e. blue LED may begin
flashing indicating it will transition lights soon)
E To check auto selected setpoint, press and release button 4 times. Setpoint will be
blinked back in two alternating digits:
Blue LED = 10's digit (1-9 blinks or rapid blink or 0)
White LED = 1's digit (1-9 blinks or rapid blink or 0)
