Xantech MRC44 installation instructions Advanced/Expanded Programming, Polarity of Sense Input

Page: 34 Model MRC44

Polarity of Sense Input

TIP: +12VDC

RING: Input (+12VDC)

SLEVE: Ground

When using a dry contact closure to activate a Current Sense Input Trigger, the switch should be between TIP and RING.

When using an external voltage, (12 volt control out from switched outlet, etc.) the switch should be between SLEVE and RING.

Current Sense De-Bounce Settings

“De-Bounce” is the amount of time switches and relays need to stabilize. The factory default of ‘2’ should be tried first. For a faster switch, try the ‘1’ setting. For slower switches change as needed to allow the controller to sense the switch or relay condition.

Transferring The Project (BASIC)

The project can now be transferred to the MRC44 if it is being set up in the Basic mode. For Advanced and Expanded systems, continue to next section. See page 41 “Transferring a Project” for instructions.
