How do I wire C18 series partition sensors to my UHCI?
- SGM1639 (receiver)
- SGM1640 (emitter)
- Connect the brown wire from both the receiver and the emitter to +24V.
- Connect the blue wire from both the receiver and the emitter to common.
- Connect the black wire (N.O.) or white wire (N.C.) from the receiver to a UHCI contact input (pins 3-10 on J4).
- The yellow LED on the receiver will illuminate when it is in line of sight of the emitter and will turn off when the beam is broken.
