MAINTENANCE

5.3Repairs and modifications

Repair of the HS50 units is limited to replacement of damaged cables, Sensor unit, Processing unit, or Display unit.

Replacing damaged cables

Power off the Processing unit and dismount the damaged cable. If the connector is not damaged it may be re-used, else a new connector has to be made available.

Assemble the connector to the new cable as described in the wiring information for the damaged cable. Refer the INSTALLATION section, page 9 onwards.

Terminate the cable to the Processing unit as described in Cable connections, page 19.

Replacing damaged units

No HS50 units are designed for service in the field, and a damaged unit has to be shipped back to Simrad for repair.

Caution! Opening the Sensor unit housing may result in permanent damage to the unit!

Install the new unit according to procedures described in the

INSTALLATION section, page 9 onwards.

5.4Troubleshooting

A GPS compass is a complex system and performance is dependent of a proper installation and a successful sea trial.

In case of a failure, the user will be helped by the Display unit, which contains several test features that will assist you in isolating a probable fault.

Pressing any button resets the audible alarm. The visual alarm will remain and alternate with the operating display until the fault has been rectified. Refer to the table below for hints and try to solve the problem yourself, or consult your nearest Simrad dealer for assistance.

The next sections contain some hints for troubleshooting.
