CAUTION
Current sensor function / simulation
The use of the current sensor function and the simulation in safety applications can result in undesirable operating states.
The use of both functions is not permitted in safety applications.
Operation/configuration
While operating/configuring, ensure that the technical data of the temperature transmitter in the respective device version is
adhered to.
Checking the safety function
We recommend for both transmitters:
● Check the status for warnings and alarms.
● Check the upper and lower alarm current values.
● Perform a 2-point calibration.
● Check the measuring accuracy that must be in the range of ± 2% for the safety function. Check the measuring accuracy,
e.g. with a sensor calibration.
● Check triggering of the safety function.
