E-STOP button and key switch
This module slot is equipped with a standard non-wired E-STOP button. The
two N/C contacts of the switching elements can be wired with the E-STOP
circuits of the machine as required.
The red-yellow E-STOP button of the VAM 10.2/VAM 40.2 complies with the
requirements of the EN ISO 13850. It has to be designed as an E-STOP of
category 0 or 1 (see EN 60204-1 chapter 9.2.5.4.2) based on the risk assess‐
ment for the machine. The connection of the positive-break contacts to an ap‐
propriate monitoring system must meet the category (acc. to EN ISO
13849-1) defined via the risk assessment (acc. to EN ISO 14121-1) of the
machine.
The connections of the both NC contacts ("NC") are labeled with "1" and "2"
in the following illustration.
