Lowering and hoisting the transducer using the Hoist/Lower
Switch
The Operating Panel controls the lowering and hoisting of the transducer. Dedicated
buttons are provided for the physical transducer locations. You can also do this from the
Motor Control Unit. Local control is useful for maintenance purposes.
Prerequisites
You need a suitable screwdriver
or a large coin to open the
Motor Control Unit cabinet.
3-phase voltage for the hoisting
motor and +24 VDC from
the internal power supply are
available. Both indicator LEDs
inside the Motor Control Unit
are lit.
Context
Use
Hoist/Lower Switch
in the upper part of the
cabinet to control lowering and
hoisting. For normal operation
from the Operating Panel, the
switch must be set to REMOTE.

sufficient water depth
below the keel before you lower the transducer.
If your vessel is in dry dock, make sure that you have sufficient height between
the hull and the dry dock floor. The space under the hull must be free from tools,
scaffolding, personnel and other obstacles.
