Table 2: Pin assignments for the control system
PowerGood (A-1):
The signal indicates to the safety device whether the power supply of the lift is OK. During emergency power
operation, the safety device is separated from the power supply 10 sec. after the car is stopped to avoid loading
the supply batteries unnecessarily.
Error (A-2):
The output indicates that an error which must be reset manually has occurred in the device. A small signal lamp
can be operated on this output. Alternatively, the error can be read on the display.
Door zone (A-3, A-8):
The two door zone inputs indicate that the car is currently in a door zone. They must be independent of one
another (2-channel).
The door zone inputs must be monitored by a tested safety circuit bypass control (EN81-1, 14.2.1.2) which
prevents operation of the lift in case of an error (EN81-1, 14.1.2.3.2.1.).
The door zone inputs are not connected, if the installation has no door bypass (the safety circuit bypass control).
Override (A-4):
If the override input is set to GND, the solenoid energises. It is used for freeing persons. If the safety device is
supplied with power (PowerGood), an error is detected, that ensures that the safety circuit is opened. The over-
ride input also functions in the event of a power failure, since this function is supplied by the emergency power
battery. If override is not active, the input must be high impedance.
Attention: The car must not be moved if the solenoid is deenergised, since the safety brake is then active. The
emergency release should remain locked until the override is active.

The unspecified input levels can be set to the opposite potential or be high impedance
