The intensity of the light of controlled light fixtures will
depend on the amount of light received by the photocell
connected to the analog input of the switch. Care must be
taken to assure the correct light level at the work surface.
The feedback percentage of the photocell is dependent upon
many factors. Things such as: type of light fixtures, colors,
textures, reflected light, or shadows, just to name a few, can
make a difference in the reflected light level.
The closed-loop control can only control the local switch
analog output.
Setting the minimum, maximum, and default
output levels
A “Minimum” and “Maximum” output level can be set
for comfort, safety or to clamp the dimming level for extra
energy savings. The “Default” level is the analog output
setting that will be set at initial startup or after power
loss situations.
To edit the “Minimum” value, click the “Minimum” input box.
This opens the box for editing.
Input the required numeric value for minimum percentage
for the feedback level from the photocell.
To edit the “Maximum” feedback level value, click the
“Maximum” input box.
This opens the box for editing.
Input the required numeric value for the maximum
percentage for the feedback level from the photocell.
To edit the “Default” feedback level value, click the
“Default” input box.
This opens the box for editing.
Input the required numeric value for the default setpoint
percentage for the feedback level from photocell at for
power up.
Setting sensor 2 as a motion sensor
dry-contact input
The “Sensor 2” digital input is only available on the 2-button
and 4-button digital switches.
The motion sensor is a maintained type of input that
controls a digital point in the host PRC-E controller. The
digital point is turned ON when the input is closed, and
turned OFF when the input is open. The “MOT_EN2” is the
internal switch point to enable and disable “Sensor 2” input.
For instruction on programming, please see the “Setting
Sensor 1 as a Motion Sensor Dry-Contact Input” section of
this guide.
