Pneumatic Pressure Switch Be sure to read before handling. Refer to front matters 58 and 59 for Safety Instructions and pages 687 to 691 for Pressure Switch Precautions. 1. Since the light emitting diode (LED) is used for the light assembly for 24 VDC, there are 2 terminals and polarity. One is “+” for red load wire and the other is “–” for black load wire. Light will not light up if wired incorrectly. 2. Light ass'y for 24 VDC has 3 mA of current leakage. Connect the LED directly to the power supply if the input of the PLC sees the switch as closed at all times due to leakage. Ex. 1) When...
