Checking the transducer lower and hoist functionality
The hull unit provided with the SC90 is designed to lower the transducer down below the
ship’s hull when the SC90 shall be used. This is a key functionality of the SC90. It is very
important that the hoist/lower function is tested before the SC90 is put to operational use.
In order to test the lower and hoist functionality of the hull unit, two tasks must be done
simultaneously. Two persons are required.
• One person must stay on the bridge in order to operate the SC90.
• One person must stay in the sonar room to verify that the Transceiver Unit starts, and
that the hull unit works properly.
Certain steps in the two procedures are location specific.
• The steps marked [ Sonar room ] are done in the sonar room.
• The steps marked [ Bridge ] are done on the bridge.
Note
Proper oral communication must exist between the bridge and the sonar room. In the
event of problems or malfunctions:
1 Locate the
Motor Protecting Switch
(S301).
2 Set the switch to position OFF.
