EN81-1 Conform Wiring with One Motor Contac-
tor
In order to use the L7Z with one motor contactor instead of two while keeping compliance to the
EN81-1:1998, the following rules have to be followed:
• The hardware base block function using the terminals BB and BB1 must be used to enable / disable the
drive. The input logic must be PNP.
• If the elevator safety chain is opened, the inverter output must be cut. This means that the base block sig-
nals at the terminals BB and BB1 must be opened, e.g. via an interposing relay.
• The base block monitor function must be programmed for one of the multi-function outputs (H2- =
46/47). The regarding digital output contact must be implemented in the contactor supervision circuit of
the controller in order to prevent a restart in case of an inverter base block or motor contactor malfunction.
• All contactors must be conform to the EN81-1:1998, paragraph 13.2.
Fig 2.13 shows an EN81-1:1998 wiring example.
