Fig. 4-42 Active cooling module
An active cooling module can also
be fitted at the outlet of the system
to enable additional cooling of sub-
assemblies.
Fig. 4-43 Internal Temperature Sensor
Temperature is monitored in the in-
dividual heat zones by means of
sensors which are located directly at
the conveyor level. A sensor for
measurement of the interior temper-
ature is connected at each nozzle
field.
Tolerances and limit values which
are intended to trigger an alarm can
be selected as desired by the user.
