Operating Instructions MGB-L0...AR.-... and MGB-L0...AP.-...
Important:
Ì The user is responsible for the integration of the device in a safe overall
system. For this purpose, the overall system must be validated, e.g. in ac-
cordance with EN ISO 13849-2.
Ì Correct use requires observing the permissible operating parameters (see
section 12 Technical data, page 28).
Ì If a product data sheet is included with the product, the information on the
data sheet applies in case of discrepancies with the operating instructions.
Ì In the estimation of the PL for the overall system, a maximum value of 100
years can be assumed for the MTTF
d
according to the limit value in EN ISO
13849-1:2008, Section 4.5.2. This corresponds to a minimum value for the
PFH
d
of 2.47x10 -8 /h.
Ì When up to 10 devices are connected in series, these limit values can be
assumed for the entire switch chain as a subsystem. As a subsystem, this
switch chain achieves PL e.
Main differences between MGB-AP and MGB-AR

If series connection is not necessary, the number of terminals can be
reduced using this system family.

several safety doors can be very simply polled using one evaluation unit or
two control system inputs.
