VACC NOT OK
Kone · Elevator Control
¿Qué significa 1078 ?
The motor controller (codes 1078, 2078, 3078) has detected that the accessory voltage (VACC) is not within acceptable limits. This indicates a problem with the auxiliary power supply. The specific lift reaction is controller dependent.
Causas comunes
- Auxiliary power supply fault (e.g., overvoltage, undervoltage).
- Short circuit on an accessory output drawing excessive current.
- Internal power supply regulation fault within the controller.
