Architectural Dimming CRESTRON GREEN LIGHT™

To power the modules externally from a Cresnet 24 VDC power supply, connect the external power supply to

the EXT and G pins on the POWER supplied connector as shown in the following diagram.

Providing Cresnet Power Externally

When properly connected and receiving 24 VDC power externally, the green LED next to the MODULES port

will light.

Under normal operation, each lighting module will draw power from the line voltage on circuit 1. In this case

the green PWR LED on the module will be lit. If AC power to circuit 1 is interrupted for some reason (e.g.

because the breaker trips), the module will automatically draw power from the 24VDC supply, if available. In

this case, the PWR LED will flash.

OVERRIDE Port Wiring

Low-voltage input devices such as the Crestron GLS-PLS-120/277 phase-loss sensor or any device that

provides a dry contact closure can be connected to the supplied OVERRIDE connector on the bottom of the

cabinet.

When a dry contact closure is applied to the OVERRIDE terminals, all modules in the cabinet will enter into

Override mode. In this mode they will recall their override levels, and will ignore any external commands (e.g.

from keypads, touchpanels, or timeclock events) until the override contacts are removed.

For more details, refer to “Override Mode” on page 11.
