1.1 Temperature probes
The 16 PTC-type temperature probes have a different meaning depending on the software
configuration given to the machine’s configuration parameters.
Terminals 1 to 16: temperature probe inlets.
Terminals 1-bis to 16-bis: temperature probe references.

Temperature probes verification procedure:
•
disconnect the power supply to the unit;
•
disconnect the probe from the microprocessor’s terminals;
•
using a digital Ohmmeter, measure the probe’s resistance value;
•
measure the temperature near the probe cap;
•
compare the measured resistance value with the one shown in the table: the
corresponding temperature should be approximately the same as the measured one.
