Section 3: Initial control programming
This section explains each step for properly completing
initial control programming settings on a CL-7 voltage
regulator control and back panel. Check the System Line
Voltage rating on the regulator nameplate. Refer to the
regulator service manual as identified on the regulator
nameplate for additional information on the regulator.
This section covers standard set-up procedures for controls,
including control replacement. Refer to
and reconfiguring for different voltage systems
installing/replacing the CL-7 control and reconfiguring the
regulator for a different voltage system.
1. Start with all switches on the control front panel turned
OFF
.
2. There are two options for powering the control: internal
power or external power. Select one method and follow
the appropriate step.
a.
Internal Power
Turn POWER switch to
Internal
from the
Off
position.
b. External Power
Apply external source to the EXTERNAL SOURCE
binding posts: hot lead to black, top binding post;
neutral lead to white, bottom binding post; ground
to green ground binding post. Refer to
Control Front Panel: Connecting power to external
for detailed instructions on applying
power to the external source terminals.
Turn POWER switch to
External
from the
Off
position.
Basic programming
Set the parameters in
to program the control
for basic operation. Continue with the steps in
to program the control for reverse power and additional
features.

After turning on the control and the LCD displays the
results of the Self-Test, press
ESC
for further keypad
use.
Step-by-step programming instructions are included in
. The Instructions column lists keys to
press (i.e.; ENTER, Edit, 7, etc.). Also, italicized instructions
denote a choice or an entry; Value denotes a desired value
entered via the numeric keypads; and following each
“Scroll” is an italicized list of alternatives that appear in the
display, within that function code. Scroll through the list until
the desired alternative is selected, and then press Enter.
Perform a Demand Master Reset (FC 38) after completing
the initial control programming to reset to present demand
values.
