Warner Electric MCS-638-4 - Manual (Page 2)

Programming
1.Connect the supply
voltage to the wires noted
in the wiring diagram.
2.Aim the light spot at the
target mark. For glossy or
reflective surfaces, the
sensor should be angled
at 10° to 15° off the perpendicular axis from the target.
3.Press the Teach push button on the sensor or apply V+
to the Teach Input for a minimum of 50 milliseconds. The
LED should flash slowly (at a rate of approximatel 1 Hz).
4.Aim the light spot at the background.
5.Press the Teach push button on the sensor or apply V+
to the Teach Input for a minimum of 50 milliseconds. The
LED will now turn on when the target mark is present
and off when it is absent after a successful teach. If the
teach was not successful or the contrast was not
sufficient, the LED flashes quickly (at a rate of
approximately 4 Hz). Programming the MCS-638 as
indicated above sets the switching threshold exactly in
the middle of the target and background values. The
above procedure is for Light Operate mode. For Dark
Operate mode, reverse steps 2 and 4.
