Operating Instructions Safety Monitors SFM-...
These operating instructions are valid only
in combination with the manual of the safety
monitor and the manual for the configuration
software!
You will find this documentation on the CD
with the ASiMon configuration software or at
www.EUCHNER.de.
Correct use
EUCHNER SFM‑... series safety monitors monitor
all safety‑related bus users on the AS‑Interface bus
Safety at Work. A machine is put into the safe state
via the safety outputs of the safety monitors.
In this application, the safety monitor performs
a personal protection function.
Correct use includes compliance with the relevant re‑
quirements for installation and operation, for example
f
EN ISO 13849‑1, safety related parts of control
systems
f
EN 60 204‑1, electrical equipment of machines
f
IEC 62061, Safety of machinery ‑ Functional safety
of safety‑related electrical, electronic and program‑
mable electronic control systems.
Safety precautions
Safety monitors perform a personal protection func‑
tion. Incorrect installation or manipulation can lead
to severe injuries to personnel.
A complete safety‑oriented system generally
consists of several signalling devices, sensors
and evaluation units. The manufacturer of a
machine or installation is responsible for correct
and safe overall function.
The monitor is classified in Category 4 accord‑
ing to EN ISO 13849‑1. The classification of the
overall machine depends on the classification of
the bus users and the connection of the outputs.
Configuration must be password protected, and
the configuration log must be printed and signed.
All safety precautions and specifications in the
manual of the AS‑Interface safety monitor used
and in the manual for the configuration software
must be observed.
Functioning
When used correctly, EUCHNER SFM‑... series safety
monitors allow the operation of sensor‑controlled per‑
sonal protection equipment and other safety compo‑
nents as AS‑interface slaves in all categories up to and
including Category 4 according to EN ISO 13849‑1.
The safety monitor also performs the EMERGENCY‑
STOP function (stop category 0 or 1), which is manda‑
tory for all machines that are not manually controlled,
including dynamic monitoring of the restart function
and the contactor‑monitoring function.
The machine is put into the safe state via the safety
outputs of the safety monitor.
The AS‑Interface safety monitor is appropriately
configured using configuration software (refer to the
configuration software manual).
Assembly
Installation must be performed only by authorized
personnel.
It is essential to fit the enclosed cover in order to
protect against electrostatic interference during
operation (see Fig. 3).
The cover must be sealed to prevent tampering.
The safety monitor must be installed in a suit‑
able operating area (switch cabinet, protective
housing ‑ at least IP54).
The safety monitor is mounted by clipping it
onto a standard 35 mm DIN rail according to
DIN EN 60715 TH35 (see Fig. 1).
f
The monitor can be removed by firmly pressing
against the upper rail guide and lifting it out.
Fig. 1: Mounting the safety monitor
f
To remove the coded connection terminals, push
away locking spring a and pull off terminal to the
front (see Figure 2).
f
On fitting, the connection terminal must engage
with a click.

minals
f
Fit cap and lock with wire and seal (see Figure 3).

Refer to the manual of the safety monitor for further
instructions.
Electrical connection
Electrical connection must be performed only
by authorized personnel.
A power supply unit with electrical separation in
accordance with IEC 60742, PELV, must be used
to power the safety monitor and all AS‑Interface
components.
Electrical connection of the safety monitor is realised
by means of screw terminals.
It is essential to adhere to the following tightening
torque values, line cross sections and insulation
stripping lengths:
