Operating Manual: PSS 3075-3 Series
Example: Single-channel, failsafe input device, without test pulse
Features:
• Depending on the application area and its respective regulations, this
connection diagram is suitable for input devices with frequent and
infrequent operation in accordance with EN 954-1, up to category 2.
The possibility of a short circuit occurring in the external wiring between
different inputs or against L+ must be eliminated through appropriate
wiring.
• The input device must be approved for failsafe applications.
• Please read the instructions provided with the input device.
CAUTION!
A short circuit in the cable between the input device and input with the L+
line or between adjacent inputs will not be detected. Neither will a short
circuit between several input devices be detected. Depending on the type
of input device connected, this could create a risk to both personnel and
machinery (e.g. E-STOP). Always ensure that the unit is suitably wired to
eliminate the risk of short circuits.
