Use in safety instrumented systems Temperature transmitter iTEMP TMT82
20 Endress+Hauser
Checking the operational state
8.
A0053704
2 Operational state indicated
Check the operational state of the transmitter (SIL mode) prior to use in safety
instrumented systems.
9. A commissioning check must be performed prior to commissioning the transmitter in
safety instrumented systems. → 25
The current configuration of the transmitter in the SIL mode can be checked using the
handheld operating device FC475, for example.
Parameters to be tested Use of function key sequence on the FC475 (HART7)
Operational state (SIL mode active) 3 → 3
Lower measuring range (4 mA) 3 → 6 → 3
Upper measuring range (20 mA) 3 → 6 → 4
PV 3 → 7 → 3 → 1
Sensor type 1 1 → 3
Sensor type 2 1 → 8
Connection type 1 1 → 4
Connection type 2 1 → 9
Sensor offset 1 3 → 5 → 1 → 6
