Series-wiring can be set up. In the case of a series connection, the risk time remains unchanged and the reaction
time increases by the sum of the reaction time of the inputs per additional unit specified in the technical data. The
quantity of devices is only limited by the cable drops and the external cable fuse protection, according to the
technical data. Series-wiring of up to 31 AZM300 … SD components with serial diagnostics is possible.
The application examples shown are suggestions. They however do not release the user from carefully checking
whether the switchgear and its set-up are suitable for the individual application. The application examples shown
are suggestions.
Wiring example 1: Series-wiring of the AZM300 with conventional diagnostic output
The voltage is supplied at both safety inputs of the terminal safety component of the chain (considered from the
safety-monitoring module). The safety outputs of the first safety component are wired to the safety-monitoring
module.
Y1 and Y2 = Safety outputs → Safety monitoring module
Wiring example 2: Series-wiring of the AZM300 with serial diagnostic function (max. 31 components in
series)
In devices with the serial diagnostics function (ordering suffix -SD), the serial diagnostics connections are wired in
series and connected to a SD-Gateway for evaluation purposes. The safety outputs of the first safety component are
wired to the safety-monitoring module. The serial Diagnostic Gateway is connected to the serial diagnostic input of
the first safety component.
Y1 and Y2 = Safety outputs → Safety monitoring module
SD-IN → Gateway → Field bus
