On safety
This chapter deals with your own safety and the safety of the equipment operators.
Please read this chapter carefully before working with a UE 440/470 or with the
machine protected by the UE 440/470.
2.1
Specialist personnel
The safety controller UE 440/470 must be installed, commissioned and serviced only by
specialist personnel. Specialist personnel are defined as persons who…
$
have undergone the appropriate technical training
and
$
who have been instructed by the responsible machine operator in the operation of the
machine and the current valid safety guidelines
and
$
have access to the operating instructions of the UE 440/470 and have read and
familiarised themselves with them
and
$
have access to the operating instructions for the protective devices (e.g. C 4000)
connected to the safety controller and have read and familiarised themselves with them.
2.2
Applications of the device
The safety controller UE 440/470 is a configurable controller for comprehensive
implementation of safety applications.
The device corresponds to category 4 according to EN 954-1; applications can reach SIL3
according to IEC 61508. The emergency stop function in the device corresponds to stop
category 0 or 1 in accordance with EN 418.
Opto-electronic and tactile safety sensors (e.g. light curtains, laser scanners, reset devices,
sensors, emergency-stop devices and machine cycle contacts) are connected to the safety
controller and are linked logically. The accompanying actuators of connected machines or
systems are switched off safely via the switching outputs of the safety controller.
Connected pick-ups or safety sensors and the subsequent control, wiring and installation
must correspond to the required category in accordance with EN 954-1.
