guaranteed if the sub-assembly is not operated in accordance with its intended
use.
The unit must be operated by qualified staff in accordance with these operating
instructions.
Safety and correct functioning of the unit and connected systems cannot be
guaranteed if operated in any way other than that described in these operating
instructions.

Pin 1: AS-i+, Pin 3: AS-i-. Use of the pins 2 and 4 is only permitted in conjunction
with the E70211 infrared addressing adapter. Any other use of the socket leads
to the destruction of the unit!
Safety instructions
The connection of the unit and any maintenance work to be carried out while
voltage is applied must be performed by qualified staff.
If a failure cannot be removed, the unit must be taken out of operation and mea-
sures be taken to avoid that it is inadvertently put back into operation.
Repair work must be carried out by the manufacturer only. Tampering with or
modifications to the unit are not allowed and void the warranty.
The responsibility for the adherence to local safety standards lies with the opera-
tor.
Introduction to the AS-interface version 2.1
The functionality of AS-interface has been expanded to support the operation of
up to 62 AS-interface slaves on one line. Moreover, the transmission of analogue
values with AS-interface version 2.1 and higher is as simple as the transmission of
binary values.
For the addressing unit described in these operating instructions, only the extensi-
on to 62 slaves is relevant and described below.
For using the extension it is important that both the slaves and the master support
AS-interface version 2.1.
AS-interface provides 5 bits for the address in the master request message.
