• Monitor the ON/OFF status of the H1 and H2 signals and confirm the EDM signal by referring to
If the ON/OFF status of the signals do not coincide with the display, the following must be considered: an error in the
external device, disconnection of the external wiring, short circuit in the external wiring, or a failure in the drive. Find the
cause and correct the problem.
• In normal operation, confirm the EDM signal by referring to
◆
EN81-1/20 Conform Circuit with one Motor Contactor
The safe disable circuit can be utilized to install the drive models CIMR-L
in an elevator system using only one
motor contactor instead of two. In such a system the following guidelines must be followed to comply with EN81-1 or
EN81-20:
• The circuit must be designed so that the inputs H1 and H2 are 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 EN81-1 or EN81-20.
• The safe disable inputs H1 and H2 must be used to enable/disable the drive. The input logic must be set to Source
Refer to Sinking/Sourcing Mode Selection for Safe Disable Inputs on page 55
for details on setting jumper S3.
The figure below shows a wiring example.
Note: 1.
The drive output will immediately shut off when either of the inputs H1 or H2 is opened. In this case the brake should apply
immediately in order to prevent uncontrolled movement of the elevator.
2.
Terminals H1 or H2 must be closed prior to setting the Up/Down command.
