Information
Installation and commissioning have to be documented by means of an assembly
report and an inspection certificate. Installation and commissioning may only be
performed by authorised personnel who have been trained on functional safety.
The plant operator is responsible for ensuring power supply including overvoltage
and undervoltage protection during execution of a safety function.
The PIN assignments (XK ...) mentioned in this chapter (and also in other chapters)
are considered as standard assignments of AC 01.2- 22X/- 22Y/ACExC 01.2- 22X/-
22Y. In certain configurations, this typical assignment is not respected with the ob-
jective to meet specific equipment demands. In case of doubt, the assignment as
indicated on the pertaining wiring diagram is applicable.
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.
The SIL fault must be connected to an input compatible with the required SIL level
of a safety PLC and subsequently analysed.

Input switching behaviour of
OPEN/CLOSE :
Input level = high level (default: +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
The Safe ESDa and Safe ESDb inputs are redundant inputs for the same safety
function (depending on the configuration ESD OPEN or ESD CLOSE). Therefore,
the same level (high or low) should be applied to them. If "high" is applied at one of
the two ESDa or ESDb inputs and "low" at the other, this represents a fault state
within the safety instrumented system. In this instance, the actuator signals a "SIL
fault". Since it is not clear whether the "high" level input or the "low" level input is
faulty, the safety function is performed for safety reasons.
