Scope
These operating instructions are valid for all CET.-AR-...-AH-... versions. These
operating instructions and the enclosed data sheet form the complete user infor-
mation for your device.
Correct use
The safety switch CET-AR is an electromagnetic interlock device with guard locking.
The safety switch CET-AR can be integrated into an AR switch chain or operated
as a separate system.
In combination with a safety guard and the machine control, this safety component
prevents the safety guard from being opened while a dangerous machine move-
ment is being performed.
For the control system, this means that
Ì starting commands which cause hazardous situations must become active
only when the safety guard is in protective position and the guard locking is in
locked position. The locked position of the guard locking must be released only
when the hazardous situation is no longer present.
Before safety components are used, a risk assessment must be performed on the
machine in accordance with
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design, Annex B
Ì EN ISO 12100, Safety of machinery – General principles for design – Risk as-
sessment and risk reduction.
Ì IEC 62061, Safety of machinery - Functional safety of safety-related electrical,
electronic and programmable electronic control systems
Correct use includes compliance with the relevant requirements for installation and
operation, in particular
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design

The safety switch is only allowed to be operated in conjunction with the intended
EUCHNER CET actuators and the related connection components from EUCHNER.
On the use of different actuators or other connection components, EUCHNER
provides no warranty for safe function.
Connection of several devices in an AR switch chain is permitted only using devices
intended for series connection in an AR switch chain. Check this in the instructions
of the device in question.
A maximum of 20 safety switches are allowed to be operated in a switch chain.
