Car and hoistway
Stop switches
Operated (open) switches break the safety string or the car-stop branch. Use them to check the string with the meter.
Job configuration
Adjustments
Z44 run stall time (default 20 = 2.0 s), P17 up slowdown and P18 down slowdown (counts of 1/40 in; 939 and 683 are the manual's 100 fpm values). Halve P17 to run the terminal slowdown test: the car reaches the terminal slowdown magnet too fast and logs 1062 and 981.
UIT (user interface tool)
Digital meter
Jumpers and fuses
Fuses (pull / replace)
Jumpers are temporary. Bypassing a safety device is for troubleshooting only and must be removed before the car is returned to service. Fuse buttons pull a fuse (blown) or replace it.
Test points
Controller fault log
Inject a fault (instructor)
Live IOD ports (manual Table 1, metered logic, electronic starter plus HWA). Red bits differ from the expected idle pattern; x is not checked.
Switch the mainline OFF and meter CCH to CCL or HC1H to HC1L in ohms: healthy is 60 ohm +/-3. Use Remote FAST or the UIT for DCN, DHNF, TECB, TECCR, TECF, TECC and TECCV.
