Description
The
System Protection
page allows you to specify alarm limits for the hull unit and the
transducer. Additional system protection features are also listed. These function are
automatically monitored by the software in the ST90 system. You are not permitted to
change the alarm limits.
If an alarm limit is exceeded a relevant message is issued by the ST90 system. At the same
time, the relevant descriptive text is provided with a dark background.
Details
Transducer
Tx Inhibit Hull Unit Position
If the transducer is activated when out of the water it may be damaged beyond
repair. With the transducer fully retracted, no transmissions ("pings") take place.
When you lower the transducer into the water, you can specify a vertical position
for when the transmissions start. When the transducer is retracted, transmissions
will stop when the transducer reaches the same position.
This functionality is only available if a hull unit has been activated in the user
interface.
