4. Exclusion of liability and warranty
Liability or warranty is ruled out in case of:
Ì
Incorrect use
Ì
Failure to comply with the operating instructions and the safety regulations therein
Ì
Failure to perform the required check for correct function
Ì
Changes to the device
5. General safety precautions
Safe operating mode selectors fulfill personnel protection functions. Incorrect installation of the subsystem or tampering
can lead to fatal injuries to personnel.
Observe the following safety regulations to prevent failure of the personnel protection function:
Ì
Visually inspect all components for damage prior to mounting and connection. Do not use damaged components; file a
complaint with the manufacturer instead.
Ì
Do not modify or replace plugs or cables.
Ì
Check the safe function of the device as a subsystem, particularly:
-each time after initial setup
-each time after replacing the device
-each time after correcting an error
-in accordance with the machine’s maintenance schedule
6. Function
The device is part of a higher-level overall system for selection of operating mode on safe control systems.
The device consists of a reader and various smartcards. Authorizations for selecting various operating modes are stored
on the smartcards.
After being read in the reader, the smartcard is checked for validity based on specific parameters. If the smartcard is rec-
ognized as valid, the operating modes available for selection can be displayed on the machine’s touch panel.
The selected operating mode is transmitted via the device’s safety outputs FO1A to FO1F to the safe control system of the
machine acting as the activation system. The safe control system must be capable of processing 1-of-n signals.
Each 1-of-n state maps an operating mode MO (
