FANUC Alarm PNT2-183 — Intermittent Connection Detected

Description

A reading of 0 counts on the analog inpit (AIN[1,DISP]) causes the alarm, intermittent connection. This is an indicator of potentiometer trouble during job playback, caused by an open/short circuit in cylinder position feedback. This alarm only occurs during a job or color change in auto mode. Regular, but not consistent postings of this alarm indicates a poor electrical connection in the feedback circuit. The electrical connector at the quick disconnect plate, when damaged or worn, can cause this alarm. Induced noise in the feedback circuit from poor grounding leads to this temporary condition as well. Resistors inside the robot controller set the supply voltage to the linear potentiometer and it should be 10 Volts.

Remedy · Remède

Replace the electrical connector on the quick disconnect plate. Verify proper grounding of the feedback circuit. Replace the low voltage cable in the robot arm. Check the supply voltage to the linear potentiometer.
