Table 4-2 Rotary Switch S1 Position for 5-Step CCRs

If you set switch S1
to the following...
REM
OFF
1
2
3
4
5
For regulator operation by +48 Vdc or 120 Vac remote control
signals, rotary switch S1 must be set to REM. Remote control is
disengaged when switch S1 is set to any position other than REM.
See Figure 2-4. Refer to Table 4-3 for setting up remote control.

Table 4-3 Setting Up Remote Control

If...
The rotary switch S1 is set to
position REM and remote control
wiring is connected to remote
control terminal block TB2 on the
regulator
Switch S1 is set to OFF
Switch S1 is set to REM
No remote control connections
exist on terminal block TB2, that
is, switch S1 is set to REM
More than one remote intensity
is accidentally selected
To shut down the CCR, perform the following procedure:
1. See Figure 2-4. Set rotary switch S1 (6) to position OFF.
NOTE: Power to the output terminals (10) is now off, and the
regulator cannot be energized by remote control signals. Power
is still present on the input power terminal TB3 (12).
2. Disengage disconnect switch or external circuit breaker to
remove input power.

The result is...
Operation of CCR by remote control signals.
CCR off. Cannot turn on by remote control.
2.8 A current output.
3.4 A current output.
4.1 A current output.
5.2 A current output
6.6 A current output
Then...
The output current of the
regulator will correspond to the
brightness setting energized by
remote 120 Vac or +48 Vdc
control signals.
Remote control signals will not
operate the regulator, that is,
turn the regulator on to a
particular brightness setting or
turn the regulator off.
Remote control of the regulator
is possible.
The position REM becomes an
additional OFF position, that is,
the regulator is de-energized.
The highest intensity will be
selected.
