Notes:
If screened cable is used to connect sensor, then GND A terminal may be used to
connect the screen. But it is more recommended to connect screen to functional ground or
e.g. metal cabinet ground (PE).
For precision temperature measurements the proper cold junction temperature
measurement have to be considered. The device during typical operation heats up about 10
°C, what has influence on the device terminals temperature. It should be considered to move
the wiring compensation cables to extra terminals in the cabinet with stable temperature.
The cold junction temperature should be measured with external temperature sensor (e.g.
Pt100) at the external terminals then.
If the TC sensors are connected directly to the module's terminal block, it is possible to
compensate the cold junction temperature with an internal sensor. The temperature of the
cold junction measured by the internal sensor is assigned to the virtual measuring inputs
(CJC ⁰C and CJC ⁰F). The same unit for the measured temperature and the temperature of
the cold junction must be set.
