Instruction Manual

TROUBLESHOOTING

If the Smart Temperature Transmitter is not working as expected,
refer to the recommendations below.

Symptom Check/Action

No communication

•

Voltage too low

•

Check loop impedance

Fault or alarm current
(

≤

3.6 mA or

≥

22.0 mA)

•

Defective or open sensor

•

Incorrect programmed range

4-20 mA output is not correct

•

Check voltage across

transmitter

•

Reduce loop impedance

Output is fixed at 4 mA

•

Transmitter configured for

multi-drop mode

•

Change HART address to zero

Temperature reading is not
correct

•

Wrong or defective sensor

•

Check

scaling

•

Check offset value

Other symptoms not
described above

•

Call Technical Support for

assistance.
