The common reference potential is established via terminal B2.
Respect the maximum wire resistance of 500 Ω when determining the cable length. The maximum
wire length between the start input and a sensor/device is 30 m (98.43 ft) if the supply via the
control output (terminal Y1) of the start input is not used.
Additional, Non-Safety-Related Output Z1
Connect the semiconductor pulsed output Z1 to a suitable input of the logic controller if you want
to use the diagnostics pattern the output provides.
The maximum wire length between the additional output Z1 and connected equipment is 30 m
(98.43 ft).
The common reference potential is established via terminal B2.
Power Supply
Connect the terminals A1 and A2 to a power supply providing the supply voltage specified for the
device in the chapter Electrical Characteristics
( see page 26 ).
Common Reference Potential
Terminal B2 is provided to obtain a common reference potential for 24 VDC signals.
The power supplies of the connected equipment must have a common reference potential.
WARNING
INCORRECT USE OF OUTPUT
Do not use the additional output Z1 for safety-related purposes.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
