5.3 Repairs 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.
5.4 Troubleshooting
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.
