Diagnostics and troubleshooting

11.1 General troubleshooting

11.1.1 General errors

Device not responding

• Possible cause: Supply voltage does not match the specification on the nameplate

Remedial action: Apply the correct voltage

• Possible cause: The polarity of the supply voltage is wrong

Remedial action: Correct the polarity

• Possible cause: The cables do not contact the terminals properly

Remedial action: Check the electrical contact between cables and correct if necessary

• Possible cause: Load resistance too high

Remedial action: Increase the supply voltage to reach the minimum terminal voltage

No values visible on the display

• Possible cause: Graphic display is set too bright or too dark

Remedial action: Increase or decrease the contrast with the

Contrast display

parameter

Navigation path: System → Display → Contrast display

• Possible cause: The plug of the display cable is not connected correctly

Remedial action: Connect the plug correctly

• Possible cause: Display is defective

Remedial action: Replace the display

No background lighting on the graphic display

Possible cause: The electric current and voltage are not correct.

Remedial action: Increase the supply voltage and restart the device.

"Communication error" is indicated on the display when the device is started or the

display is connected

• Possible cause: Electromagnetic interference influence

Remedial action: Check grounding of the device

• Possible cause: Defective cable connection or display plug

Remedial action: Replace the display

HART communication not working

• Possible cause: Communication resistor missing or incorrectly installed

Remedial action: Install the communication resistor (250 Ω) correctly

• Possible cause: Commubox is connected incorrectly

Remedial action: Connect Commubox correctly

Communication via CDI interface not working

Possible cause: Wrong setting of the COM port on the computer

Remedial action: Check the setting of the COM port on the computer and correct it if

necessary
