Particularities for operation on decentralized pe-
ripheral systems
The version CES-I-AP-...-SI-... (M12, 5-pin; pin 5 not assigned) is optimized for con-
nection to decentralized peripheral systems with M12 plug connector, such as the
ET200pro series from Siemens. The devices are parameterized and connected
like an OSSD (e.g. like light curtains).
The 5-pin M12 plug connector can be connected directly to the socket of an IP65
field module (e.g. ET200pro). If flying leads are used, connection to IP20 input
and output modules (e.g. ET200s) is naturally also possible.
Important!
Observe the following notes prior to connection:
Ì Parameter assignment must be performed for the input/output modules (see
application example at www.EUCHNER.de, in the area Download ›› Applica-
tions ›› CES).
Ì Additionally observe notes from the control system manufacturer where nec-
essary.
Safety in case of faults
Ì The operating voltage U
B
is reverse polarity protected.
Ì The contacts FO1A/FO1B are short circuit-proof.
Ì A short circuit between FO1A and FO1B is detected by the switch.
Ì A short circuit in the cable can be excluded by laying the cable with protection.
Fuse protection for power supply
The power supply must be provided with fuse protection depending on the current
required for the outputs. The following rules apply:
