The table below lists the output ICs and fuses for the Mini I/O (CN5) and HAND I/O
(CN9). If an output signal error occurs, check the corresponding fuse.
Note: The Emergency Stop and Deadman output circuits use PolySwitches (resettable
fuses) that trip in an overcurrent condition to open the circuits. If a PolySwitch trips, turn
the power off and check the related circuit. (As long as the power is on, a PolySwitch
keeps tripping. After checking, therefore, turn the controller power off and on, then
check the circuit again.
