8 Troubleshooting

SYMPTOM

ACTION

No level reading

Check the power supply.

Check the cables for serial data commu-
nication.

Incorrect level reading

Check the transmitter calibration.

Check that the transmitter has not locked
on an interfering object.

Check that the mechanical installation is
correct.

Serial communication failure

Check the COM port setting in the Pro
Setup program.

Check the serial communication address.

Check the cable connections and that the
correct cables are used.

Insufficient power supply to Field Bus
Modem.

Display Panel window is blank

Check the power supply

Poor Display Panel contrast

Press the two right-hand buttons to in-
crease the LCD contrast.
