Main parts
(A) = Negative charging and fastening lug
(B) = Positive charging and fastening lug
(C) = Communication link to the vessel
(D) = Location of sensor lamp (rear side of PI
Twin Spread)
(E) = Water switch sensor
(F) = Transverse communication links to the two
Remote sensors
Daily operation
Once installed and put to use, the Twin Spread sensor will
automatically be switched on once the waterswitch is activated.
After an initial startup, the sensor starts interrogating the
Remote sensors to measure the two distances. The results are
transmitted to the vessel. When the sensors are not in use, check
that the sensor lamps (D) do not flash from time to time, as this
indicates that the sensor is on and is discharging its batteries. In
this case, wash the sensor in fresh water to remove salt and dirt.
If you operate with Fast update rate, the sensors must be
charged approximately every 24 hours. Used with Normal or
Slow update rates, the operational life is approximately 48 or 70
hours respectively. For the Remote sensors, the batteries will
last approximately 50, 100 and 150 hours respectively. The
optimal sensor charging temperature is from +10 to +25° C.
Note:
The two rubber inserts provided at the bottom of each sensor
adapter must not be replaced with any other types or designs. It
is essential that these inserts provide a secure cradle for the
sensors, but they must also allow for free water circulation to
allow the sensor’s water switch to engage. Also, the design of
the inserts allows sand and mud to flow out when the trawl
doors are pulled up from the water.
Note:
Note that charging sensors at sub-zero temperatures can create
explosive gasses. Simrad AS assumes no liability for the
improper charging of sensors or the use of chargers not
specified in Simrad’s sensor charging documentation.
