2 Product application for - emergency stop relay
- safety gate monitoring relay
- safety mats and safety contact edges
a) SAFE CM
(SAFE CM is adapted for safety gates and safety bars, also with load resistance)
2-channel application with auto-start and broken wire check.
The safety mat switch must close the input circuits (S11/S12,
S21/S22), and the S11-S34 has to be brigded for auto-start
configuration. The bridge between S21-S32 activates stand-alone
application (no AND connection). The outputs will be activated when
the contact areas of the mat are not connected (mat not entered)
up to category 4; SIL3; PLe reachable

2-channel application with monitoring of reset circuit and broken
wire check
.
The safety mat switch must close the input circuits (S11/S12,
S21/S22. The outputs will be activated when the contact areas of the
mat are not connected (mat not entered) and the start button is
pressed and released.
up to category 4; SIL3; PLe reachable

S33 S36 S37
1-channel application with auto start and broken wire check.
The mat with final resistance must be connected to S36 and S37. Auto start
is activated by bridge between S34-S11.
The outputs will be activated when the contact areas of the mat are not
connected (mat not entered)
For monitoring of the external conductors, the NC contacts of the
force guided contactors must be attached in series to the start circuit
