serious injury or accidental death.
Failure to follow these instructions (intended use, safety instruc-
tions, installation and connection by trained personnel, safe
function test) will invalidate any liability.
1Intended use
SIN safety switches are locking fixtures with an electromechanical
latching device and low level coding according to EN ISO 14119.
Interacting with the control system of a machine they are used to
monitor the position of moving safety guards.
In connection with the safety switches SIN, moving safety guards
can only be opened if no hazardous conditions are present.
The actuating signals in relation to hazardous situations are only
effective when the safety guard is in active position and the
latching device is in lock position.
Standards governing installation and operation:
•EN ISO 13849-1 Safety components of control systems
•EN 14119 Locking devices in connection with separating safety
guards
•EN 60 204-1 Electrical machine equipment
Risk assessment at the machine in accordance with:
•EN ISO 13849-1 Safety components of control systems
•EN ISO 12100 Machine safety, risk assessment
The safety switch can be installed in any position that enables
access to the auxiliary release mechanism as well as its inspection
and, if necessary, replacement by authorised technical personnel.
2Installation
•Do not use the safety switch and actuator as a stop!
•Foreign particles must be prevented from entering the actuator
opening when the safety guard is open.
•Installation must be carried out in accordance with EN ISO
14119. Particular attention must be paid to measures designed
to reduce the possibilities of bypassing the system.
•To maintain the safety level, the actuators can only be ordered
with the belonging safety switch in one unit.
•Replacement actuators and keys have to be securely monitored.
The same applies to keys for resetting the emergency release or
escape release function.
•The safety switch must not to be used as mechanical limit stop.
•The SLK safety position switch with escape release option must
be installed within the hazardous area.
•The escape release option can only be used in order to quit the
hazardous area in case of a system failure.
•The escape release must be on the escape side.
