APPLICATION EXAMPLE 6: SENSOR
SWITCH CM SERIES OCCUPANCY
SENSOR AND MANUAL DIMMING
This schematic presents two additional
lighting control applications. The Occu-
pancy Sensor (OS) is intended to provide
automatic on/off control while the push-
button-pair allows for manual dimming.
When wired as shown, the control
definitions are as follows:
-
Sensor
:
Type: “Occupancy Sensor”
Input: 1:9I “DINA”
Exit Time: 15 (T in Minutes)
Output: (Ballast Load) ON
-
Top Push-button
:
Type: Momentary (+|-)
Input: 1:18I (UI2 Digital Mask)
Step Direction: +
Step Size: 5 (0-4095)
Maximum: 100
Output: 1O (Analog Output 1)
-
Bottom Push-button
:
Type: Momentary (+|-)
Input: 1:17I (U11) Digital Mask)
Step Direction: -
Step Size: 5 (0-4095)
Maximum: 100
Output: 1O (Analog Output 1)
Each press of the top push-button will
increase the light level by 5%. Similarly the
lower push-button will decrease the level.
The Occupancy sensor would have the
load controlling the 120VAC to the light
fixtures as its control output. The switches
control dimming and the sensor controls on/
off. There are many alternatives to this
scheme. On/Off control could be handled
by another control and the OS eliminated.
Using a lower limit for acceptable lighting an
“Analog Compare” control could monitor the
output and automatically switch the lights
off when dimmed below a certain level.
OF ADDITIONAL INTEREST: This example
forgoes the use of the Dimming Cable (HIS
016-4092). The Analog Output of the
controller has sufficient drive for up to two
(2) Electronic Dimming Ballasts. If more than
two ballasts need to be attached to one
output, it is highly recommended to use the
Dimming Cable.
It is necessary to place a 500-Ohm resistor
across the Gray and Violet ballast wires to
change the controller output from 0 to 20
mA to 0 to 10 V output.
