3.2 Connection cable
The connecting cable has to be selected according to
the following criteria:
Shielded
Diameter 3 - 6.5 mm
Number of wires: 2 to 12 (as required)
- 2 for power supply.
additionally, if required:
- 1 for analog output
- 1 for sensor head temperature
- 1 GND for analogue output and /
or sensor head temperature
- 3 or 4 for digital interface
- 2 for relay contact
3.3 Connection
1. Prepare the cable as shown in
Fig. 1
.
2. The shielding of the connecting cable has to
be pushed over the plastic sleeve
2 mm further than the O-ring.
3. Fix the cable with the clamp screw.
4. At state of delivery, an internal connection
between contact 11 and the housing exists.
Should the housing have its own earth
potential caused by an electric connection to
an object, the internal connection has to be
removed.

Caution:
Before connecting the pyrometer
to other instruments (e.g. controller, PLC,
etc.), the correct analog output (current, voltage or
thermocouple) corresponding to the input of the
instrument, has to be adjusted at the converter. A
wrong output might damage the connected
instrument.
