EUCHNER CES-AP-CL2-CH (Multicode) - Manual (Page 10)

Operating Instructions Safety Switch CES-AP-C.2-CH
10
Important:
If the device does not appear to function when operating voltage is applied (e.g.
green STATE LED does not flash), the safety switch must be returned unopened
to the manufacturer.
Notes for operation with safe control systems
Important:
Devices with start button and feedback loop are not suitable for connection to
safe control systems.
Please observe the following requirements for connection to safe control systems:
Ì Use a common power supply for the control system and the connected safety
switches.
Ì A clocked power supply must not be used for UB. Tap the supply voltage
directly from the power supply unit. If the supply voltage is connected to a
terminal of a safe control system, this output must provide sufficient electrical
current.
Ì Outputs OA and OB can be connected to the safe inputs of a control system.
Prerequisite: The input must be suitable for clocked safety signals (OSSD sig-
nals, e.g. from light curtains). The control system must tolerate clock pulses
on the input signals. This normally can be set up by parameter assignment in
the control system. Observe the notes of the control system manufacturer.
For the pulse duration of your safety switch, please refer to the section Typical
system times on page 18.
A detailed example of connecting and setting the parameters of the control system
is available for many devices at www.euchner.de in the download area » Applications
» CES. The features of the respective device are dealt with there in greater detail.
Devices for direct connection to IP65 field modules
The version CES-AP-...-SB-... (M12, 5-pin; pin 5 not assigned) is optimized for con-
nection to decentralized peripheral systems, such as the ET200pro series from
Siemens. The devices are assigned parameters 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) with aid of the connection cables on page 22. If fly-
ing 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 might be required for the input/output modules (see
application example at www.euchner.de in the area Download ›› Applications
›› CES).
Ì Additionally observe notes from the control system manufacturer where nec-
essary.
