Information Operating Manual
This manual contains important information regarding the handling of the device.
For your own safety and operational safety, please observe all safety warnings and instructions.
Precondition for safe operation is the compliance with the specified safety and handling instructions.
Moreover, the existing local accident prevention regulations and the general safety rules at the site of operation
have to be observed.
Please read the operating manual carefully before starting to work with the device!
It is part of the product and should be kept close to the device and accessible for the staff at any time. The illus-
trations in the manual are for better demonstration of the facts. They are not necessarily to scale and can slightly

Mounting kit for rail mounting of the magnetic tape for safe sensors
(Safe Rail Mounting Set), can be used for the semi-guided variant.
Safe evaluation unit
Device that receives the safe position data of the sensor and cuts the safety circuit
in case of a disturbance. A safe position controller can fulfil the function of a safe
evaluation unit.
Safe position data
This position information may be used for safety functions.
Unsafe position data
Position information that may not be used for safety function due to missing redun-
dancy.
Safe state
In this mode the danger for passenger and environment is minimized. In the eleva-
tor industry, safe state means that the safety circuit of the elevator is opened and
the cabin is stopped.
Since LIMAX44 RED has no direct connection, it has to be connected to the safety
circuit via the safe evaluation unit.
