5. Installation, commissioning and operation
Information Installation and commissioning have to be documented by means of an assembly
report and an inspection certificate. Installation must be carried out exclusively by
suitably qualified personnel.
The plant operator is responsible for ensuring power supply protection against
overvoltage and undervoltage during execution of a safety function.
5.1. Installation
General installation tasks (assembly, electrical connection) have to be performed
according to the operation instructions pertaining to the device and the enclosed
order-specific wiring diagram.
When operating and storing the devices in ambient temperatures below –25 °C,
ensure power supply of integral heating system.
Safety functions are connected via the SIL module integrated in the AC 01.2/ACExC
01.2 actuator controls.
SIL fault must be connected to a SIL 2 compatible input of a safety PLC and
subsequently analysed.

Input switching behaviour of Safe ESDa/ESDb and Safe STOP
OPEN/CLOSE:
●
Input level = high level (standard: +24 V DC)
= No safety operation for Safe ESD function or
= No safe stop for Safe STOP function
●
Input signal = low level (0 V DC or input open)
= Failure operation for Safe ESD function or
= Safe stop for Safe STOP function
Permissible input voltage range:
●
High level: 15 – 30 V DC
●
Low level: max. 5 V DC
Signal behaviour of SIL ready and SIL failure outputs:
●
SIL ready (signal inactive), i.e.:
NO (NO contact) output = closed
NC (NC contact) output = open
