Measurement pyrometer connection
An digital IMPAC pyrometer must be used as
the measurement pyrometer, as otherwise the
automatic detection and configuration of the
pyrometer by the PI 6000 will not work.
The colour codes given are the standard col-
ours for all IMPAC digital pyrometers.

Digital interface
The pyrometer can be connected to the PI
6000 using its RS232 or RS485 interface. On
the usage of the RS485 interface, the jumper
between terminal 24 and 25 (fitted as standard)
must be removed.

Alarm pyrometer connection
Any pyrometer with an analogue output and
positive measuring range limits can be used as
the alarm pyrometer (optional) (2-wire or 4-wire
version to suit the application).
The power supply for 4-wire and 2-wire py-
rometers is already integrated into the PI 6000
and does not need to be connected externally.

PC or PLC connection (RS232 interface)
It is only possible to program the PI 6000 using
a PC or a PLC, the connection is made using
an RS232 interface.
To prevent earth or ground loops, the interface
is electrically isolated from the other connec-
tions on the controller. The following contact
assignments apply:
