SIMPLE FAULT FINDING

If the transmitter does not appear to be working satisfactory, carry out the following troubleshooting checks before

contacting your nearest Service Center or Factory Representative.

If the instrument is to be returned for repair, ensure that it is adequately packed using the original polystyrene box or

high-density chip foam. The Return Materials Authorization (RMA) number must be sent with the instrument.

Equipment returned to ABB Inc. with incorrect or incomplete information may result in significant delays or

non-acceptance of the shipment. At the time the RMA number is given, an estimate of the repair costs will be

provided, and a customer purchase order will be requested. The RMA and purchase order numbers must be

clearly marked on all paperwork and on the outside of the return package container (i.e., packing box).
