C.5 EN81-1 Conform Circuit with one Motor Contactor
The safe disable circuit can be used to install the drive in an elevator system using only one motor contactor instead of
two. In such a system the following guidelines have to be followed for compliance to EN81-1:1998:
• The circuit must be designed so that the input H1 is opened and the drive output shuts off when the safety chain is
interrupted.
• A drive digital output must be programmed as Safe Disable feedback (H2- = 58). This feedback signal must be
implemented in the contactor supervision circuit of the controller that prevents a restart in case of a fault in the Safe
Disable circuit or the motor contactor.
• All contactors and wiring must be selected and installed in compliance with the EN81-1:1998.
The figure below shows a wiring example.
Note: 1. The drive output will immediately shut off when input H1 is opened. In this case the brake should apply immediately in order to
prevent uncontrolled movement of the elevator.
2. The drive output can only be activated when neither an Up nor a Down command is active, i.e., terminal H1 must be closed prior to
setting the Up/Down command.
