Connect the jumper labeled “PRESET” from the second connection to the desired failsafe step (pre-wired at factory). For
example, to set CCR #1 to Step 4 in fail-safe mode, place the jumper at Connection 7 (Step 4 – B4).
•
The third connection is for CCI (controllable element control voltage).
•
The fourth through ninth connections correspond to the brightness steps for the CCR. Each step requires a separate wire
to the CCR—as shown in Table 4 .
•
Note that for ADB CCRs, B1 is not required. ADB CCRs automatically turn on to the lowest step when CCI is connected to
CC. Please refer to the regulator (CCR) manual to see if your CCR requires B1/B10 contact to be energized for CCR remote
control.
Refer to Drawings 43A4582-05 and 43A4582-10 for complete external wiring details. In addition, please see Drawings
43A4582-07 and 43A4582-11 for example fail-safe wiring connections.
3.5.3 Wiring Notes for Separate B1/B10 Control
Refer to Drawing 43A4582-8 through 43A4582-11 for wiring regulators that require a separate control line for B1 or B10.
Note that in this configuration 3-step control elements #8, #9, #11 and #12 cannot be wired with a separate B10
control line. Regulators that do not require a separate B10 control line should be used in these positions.
3.5.4 Watchdog Wiring
The watchdog is wired from the factory and does not need any field connections in order to function. The 3-position switch
on the front of the PLC assembly is used to control failsafe and watchdog functions. The positions are defined as follows.
•
TOWER– The system functions as designed where the output of the watchdog timer keeps the failsafe relays energized so
that the controllable elements are controlled by the PLC.
•
BY-PASS– The watchdog timer is bypassed and 24VDC is applied to the failsafe relays keeping them energized so that the
controllable elements are controlled by the PLC.
•
FAILSAFE– The control power to the watchdog is removed thereby removing the 24VDC from the failsafe relays. This
action results in the failsafe relay coils de-energizing and control of the CCRs reverts to the preset failsafe connection.
3.5.5 Power Wiring (TB1)
The PLC cabinet requires 120V or 230V AC input power. Power wiring is connected to TB1 as shown in Drawing 43A4582-13.
Use only 14 AWG NEC approved 600-volt wire.
