Re-wiring early ZipLoader PLC (30MR) for RTC Sensors
The two blue boxes in the photo below show where wiring must be done on the early PLC 30MR panel. Closeups of the two areas follow below, with instructions on how to re-wire the sensors.
The picture below
shows the original
sensor wires connected at the top terminal strip.
The black wires from the old sensors get replaced with brown, and the brown wires get replaced with black. The extra blue wires are all connected to the 24V terminals (see next picture).
NOTE: The brown and black wires are reversed: new BROWN wires go to 0V; new BLACK wires go to the X-numbers.
- New “Home” sensor black wire goes to X3; brown wire to 0V
- New “Slow” sensor black wire goes to X4; brown wire to 0V
- New “EoB/InPlace” sensor black wire goes to X5; brown wire to 0V
- New “Eject” sensor black wire goes to X6; brown wire to 0V
Picture shows old sensors. With new sensors black goes to X's, brown to 0V's
The picture below shows the “+24V” screw-terminal, where the extra blue wires from all sensors must be connected. You can put two wires under each of the two screws.
Four blue wires to +24V terminal.
