Solid–state Control Modules – Field Installed Modifications

500LC–47CM*, 500LC–48CM*, 500LC–49SS*

These control modules are to be connected and mounted on the bottom or

right side of the Bulletin 500LC Lighting Contactor depending on the

number of 500LC poles or N/O and N/C contact configuration. A control

module can be field installed by ordering the appropriate module kit. Refer

to wiring diagrams on page 13 or 14.

Operation

Mod. 500LC–47CM*

control modules are for two–wire control of the

Bulletin 500LC only. The module must be energized to close the 500LC, and

de–energized to open the 500LC. Therefore, use a single pole, maintained

type control station to operate the control module.
Mod. 500LC–48CM*

control modules are for three–wire control of the

Bulletin 500LC. One terminal must be energized to close the 500LC; another

terminal must be energized to open the 500LC. If neither or both terminals

are energized, no output will occur. Therefore, use a single pole, double

throw, momentary type control station to operate the control module.
Mod. 500LC–49SS*

control modules are for Form 3 (start–stop) control of

the Bulletin 500LC. The modules must be energized to close the 500LC, and

de–energized to open the 500LC. Therefore, use one normally–closed and

one normally–open separate control stations to operate the control module.
There are four different control modules for each Mod. 500LC–47CM*,

500LC–48CM*, and 500LC–49SS*. Each module is suitable only for the

control voltage marked on it. Refer to Table F. Ratings for the control

modules are listed in Table H.

Connections

Connections to the Mod. 500LC–47CM*, 500LC–48CM*, and

500LC–49SS* control modules are shown in Table G. Also refer to the labels

in Figure 1 and to wiring diagram on page 13 or 14. Barrier screw type

terminals accept #22–12 AWG Cu control wiring. Tighten terminals to 12

inch–pounds.
The control modules have two colored leads preconnected to the O and C

terminal bus on the 500LC. A yellow wire runs between the O terminals; and

orange/black wire runs between the C terminals.
Connect your control wiring for the module to terminals 2, 3, and 4 on the

modules. Terminal 2 is not used on Mod. 500LC–47CM* and terminal 1 is

never used.
Connect your control wiring for the 500LC Lighting Contactor (coil voltage)

to terminal 5 on the control module and terminal L on the500LC. If the line

voltage (service) is the same as the coil voltage, the control voltage can some

directly from the poles of the 500LC Lighting Contactor.
