3.1
Intended Use
The control interface units IVI-KHA6-4HRX/IVI-KHD2-4HRX serve as part of the in-
ductive identification system IDENT-I from Pepperl+Fuchs to connect to a high order
computer (PLC, PC) with the PROFIBUS-DP interface (DIN 19245 T1 + T2,
EN 50170).The control interface units are only to be used with the read/write heads
and the code/data carriers from Pepperl+Fuchs.
The protection of operating personnel and the system against possible
danger is not guaranteed if the control interface unit is not operated in
accordance with its intended use.
The devices IVI-KHA6-4HRX/IVI-KHD2-4HRX may only be operated by
appropriately qualified personnel in accordance with this operating
manual.
3.2
General safety information
Safety and correct functioning of the device cannot be guaranteed if any
operation other than that described in this operating manual is perfor-
med.
The connection of the equipment and any maintenance work to be car-
ried out with voltage applied to the equipment must only be performed
by appropriately qualified electro-technical personnel.
In the case that a failure cannot be repaired, the device must be taken
out of operation and protected against inadvertently being put back into
operation.
Repair work may only be carried out by the manufacturer. Additions or
modifications to the equipment are not allowed and void the warranty.
The responsibility for the observance to local safety standards lies with
the operator.

Functional safety/monitoring
The control interface units IVI-KHA6-4HRX/IVI-KHD2-4HRX operate on a micropro-
cessor basis. Functional disturbances and equipment errors/faults are signalled with
the LED "Run/Error" on the front of the device.
In addition function control via the PROFIBUS is possible by interrogating the diagno-
sis/status information. Device failure or breakdown of a read/write head can be de-
tected and indicated by the master unit.
Subject to reasonable modifications due to technical advances.
