Recording of analog measured values

Note
For the recording of analog measured values a PM4000 U/I Temperature must be available.
No links of any kind to the functionality of the heating control are available.
Analog inputs 0 ... 20 mA
Four inputs are available for recording of measured current values for a current measuring
range of 0...20 mA.
The measured current values can, for example, be used with a pyrometer for temperature
measurement.
If values are measured outside the measuring range, an error message is generated and an
invalid measured value (-32767) is displayed.
Temperature measuring inputs
Four measuring inputs are available for recording measured temperature values. Measured
values for Pt100 and Pt1000 can be recorded, as well as for thermocouples of types
J, K and L.
If values are measured outside the measuring range, an error message is generated and an
invalid measured value (-32767) is displayed.
Compensation procedure
Various compensation procedures are available for recording measured values of
thermocouples:
● Internal compensation: In this procedure, the temperature is recorded at the terminal and
included in the calculation of the temperature of the thermocouple.
● External compensation: In this procedure, the user can transmit the compensation value
for the temperature calculation of a thermocouple which is recorded, for example, by
means of a Pt100 outside the HCS.
