tech notes 4:
Check output terminals to see if voltage goes from 0 to 24VDC (for +24V to enable), or from 9-15VDC to 0VDC (for ground to enable) with volt meter at the ouutput terminals. If not replace opto 22 I/O device on digital I/O module, check fuse on CATII digital I/O module.

HP-150 PROBLEMS
Turn off HP-150 power switch (located on back of HP150), wait 30 seconds, turn on HP-150 power switch, check the Diagnostic LEDs. See HP-150 Error Codes for fault.

OVERTRAVEL LIMIT + AND OR - ERRORS:
If the machine is on a limit, press and hold the axes start button in and power feed off the limit. If not on a limit, check for +24VDC at the limit switch input (see Incon customer interconnect drawings for terminals to check). If no +24VDC check for bad limit switch or broken wire in the machine. If +24VDC at terminal change the opto 22 device. CATI & CATII controls also have a fuse on the I/O module that should be checked.

SYSTEM HAS POWER SUPPLY ERRORS THAT WILL NOT CLEAR:
Check power supplies with digital volt meter. CATI: CATI can also get error 0011 OVER TEMPERATURE TURN CONTROL POWER OFF if the 24VDC goes away. Check 13J17 1-10 for voltages silk screened on board (1&2= GND, 3&4= +5 VDC, 5&6= -12 VDC, 7&8= +12 VDC, and 9&10= +24VDC) Very old systems do not have J17, but labled test points are available. If a supply voltage is missing. Turn power off, remove all connectors with wires in on ASSY14 and J17 of ASSY13. Turn power on. Check supplies again, if still no output replace power supply. If voltages come back, plug connectors back on ASSY 13 and ASSY14 one at a time and check to see when power supply goes into current foldback. See INCON drawings and follow wiring to find short. CATII: Check F0 (System Interface Module) for voltages at test points labled with voltages. If missing a supply voltage. Check fuse on F0 and replace if blown. If fuse blows again, remove J18 and J19. Ohm out wires to find wire that may be shorted and is causing the fuse to blow. If fuse is ok and no output, replace power supply. NOTE: Limit switch wiring is the most common cause of shorts.
