2 — INSTALLATION & WIRING: 1223/33 Controllers
1223/33 Wiring Configurations
The 1223/33 controller can be configured to work with either on/off or momen-
tary switches for selecting direction and mode. If a power enable switch is used,
it must be momentary style. For more information on control switches, see p. 24.
With on/off switches
Typical wiring for the 1223/33 controller with on/off switches is presented in
Figure 3. This diagram shows the controller configured with the program 1 driver
as an electromagnetic brake, the program 2 driver as a brake light driver, and two
SPST switches used for selecting direction. NOTE: In the configuration shown, the
power enable pin is an output that drives the Status LED. With on/off switches,
the power enable function is performed by the keyswitch and a power enable
switch is not used.
