System Manual Safety System MGB-AR in Combination with a Locking Module

Information on operation in a CES-AR switch chain
System times
The locking module has longer response times than a CES-AR switch (see
Technical
data
and diagram of
Typical system times
, Figure 0 and 1).
Position in a CES-AR switch chain
The locking module must be the last device in the CES-AR switch chain (see Figure
19).
Important
: lay cables in a common harness

Output current
The safety outputs on the guard locking module have a lower maximum output
current than a CES-AR switch (see
Technical data
).
Number of devices in the switch chains
In a pure MGB switch chain a maximum of ten devices can be connected in series.
In mixed switch chains (e. g. together with CES-AR) the maximum number of devices
is also reduced to ten.
