Appropriate Use - Zander Aachen SCB Serie Betriebsanleitung

•
Installation, commissioning, maintenance, and decommissioning should be done only by
authorised and qualified technicians:
− who are familiar with proper handling of the safety components
− who are familiar with the applicable EMC and ESD regulations
− who are familiar with the local regulations concerning work safety and accident
prevention
− who have read and understood these operating instructions.
•
Opening the device, any kind of manipulation to it and bypassing the safety devices are
not permitted
•
The electrical connection of the device must take place only when the voltage supply is
switched off
•
Loads at the outputs must be disconnected from the device during device configuration
•
The wiring of the device must be according to the instructions of this user information,
otherwise there is a risk that the safety function will be lost
•
The current paths 17-18 and 27-28 must carry only the same voltage potentials
•
The device version (see nameplate "Ver.") should be stored and checked before every
commissioning. When there is a version change, the use of the device in the overall
application should be revalidated

4. Appropriate use

The SCB is a universally applicable safety time control device, with which the moving
parts of a machine or plant can be brought to a standstill quickly and safely in case of dan-
ger. Depending upon the configuration, the safety outputs connect on-delay, off-delay or
without delay independent of one another.
The approved operating parameters for use must be complied (see "Technical data").
A risk assessment should be carried out on the machine before using the device. For
example, according to:
EN ISO 13849-1, Safety-related parts of control systems, Appendix A
EN ISO 12100, Safety of machinery - General principals for design - Risk assessment and
risk reduction
IEC 62061, Safety of machinery - Functional safety of safety-related electrical, electronic
and programmable electronic control systems.
Additional requirements may have to be considered depending on the type of machine or
plant.
