5.4 Connection for 5-pole connecting cable
The 5-pole plug to connect the instrument is at the rear side of the unit. The contacts of the 5-pole plug are
arranged as follows:

5.5 Cooling connection
At ambient temperatures of more than 40 °C the pyrometer must be operated with the associated cooling!
The two connections for the connection of a cooling circuit are located under the instrument (see Drawing
pyrometer (Figure 1) at page 8).
The following should be taken into account when connecting a cooling circuit:
• Flow rate at least 1 l/min
• Pressure maximum 6 bar
• Coolant temperature 10 . . . 35 °C
Cold tap water is usually sufficient for cooling. It should not be so strongly cooled that condensation develops
on the instrument. Take into account the environmental conditions (air temperature and humidity) with respect
to the cooling.
