User Manual Description of Function Codes

27: UPS valid signal
It is the emergency running signal at power failure. If it is active, it indicates that the elevator
is running for emergency evacuation at power failure. For more details, see section 5.2.1.
28: Elevator lock signal
If this signal is active, the elevator enters the locked state, returns to the elevator lock floor
and does not respond to any calls until the signal becomes inactive. It has the same function
as the hall call elevator lock signal.
30: Shorting PMSM stator feedback signal
The shorting PMSM stator contactor protects the elevator from falling at high speed in the
case of brake failure. This signal is used to monitor whether the shorting PMSM stator
contactor is normal.
65: Door machine 1 safety edge signal; 66: Door machine 2 safety edge
signal
They are used to detect the safety edge signal state of door machine 1 and door machine 2
(if existing).
67: Motor overheat signal
If this signal remains active for more than 2s, the controller stops output and reports
fault Err39 to prompt motor overheat. After this signal becomes inactive, Err39 is reset
automatically and the system resumes to normal operation.
68: Earthquake signal
If this signal remains active for more than 2s, the elevator enters the earthquake stop state,
stops at the nearest landing floor and opens the door. Then the elevator starts running again
after the earthquake signal becomes inactive.
69: Back door forbidden signal
If double door machines are applied, it is used to prohibit the use of door machine 2.
70: Light-load signal
It is used for nuisance judgment in the anti-nuisance function. If Bit2 in F8-08 is set to 1,
the system performs nuisance judgment by using the light-load switch. 30% of rated load is
regarded as light load.
71: Half-load signal
It is used for allocation of elevators in parallel or group mode and judgment of the
emergency running direction at power failure.
72: Fire emergency floor switchover signal
The NICE3000
new
supports two fire emergency floors. By default, the elevator stops at fire
