TESTING
If desired, the dimmer may be tested without any control signal input
by moving SWITCH #8 to the off and then the on position on both of
the dimmer firing cards after the system is energized. This will cause all
dimmer channels to go to full intensity for testing load circuits. Dimmers
will ignore all control signals in this case.
NOTE:
If Switch #8 is set on before power is applied to the dimmers, then the
lighting loads associated with that firing card will come to 50% intensity
(full on for CR’s) when power comes on. This is useful for emergency
lighting purposes. The console or remote panels may take control after
light come on.
CAUTION
INSPECT INSIDE OF DIMMER PACK FOR LOOSE BITS OF WIRE OR HARDWARE
THAT MAY HAVE FALLEN ONTO THE CONTROL CIRCUIT BOARDS AND BE SURE
ALL INPUT AND LOAD WIRING IS COMPLETE BEFORE ENERGIZING ELECTRICAL
SERVICE TO DIMMER.
CONTROL WIRING
Control wiring to the 2408CD should be Class 2 wiring. All control wiring
must stay below the barrier separating the control wiring compartment
from the load wiring. All control wiring must exit out of either of the
1/2”-3/4” knockouts located in the control wiring compartment. Several
types of low voltage control inputs may be employed as discussed below.
Under no circumstances can any control signal input exceed 15 volts.
Individual 0-10 VDC control wiring
Each of the eight dimmer channels of the 2408 CD/CR may be operated
by a 0-10 VDC control voltage. This type of control will provide 0%
intensity at 0 volts and 100% intensity at 10 volts. Any or all of the
dimmer channels may be operated in this manner simultaneously with
either of the multiplex control inputs. Each dimmer will respond to the
greater of any control inputs.
Connect each of the plus control wires to the desired dimmer channel
connections (see figure 3) on each of the dimmer firing cards. Connect
the common control wire to one of the COMMON connections provided
on the power supply card. This control input impedance is 4.7K ohms.
