Once installed and put to use, the sensor will automatically be
switched on once the waterswitch is activated. After an initial
startup, the sensor will detect the status of the detection wires,
and transmit this information to the vessel. When the sensor is
not in use, check that the sensor lamps (D) do not flash from
time to time, as t his 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 35 hours. Used with Normal or
Slow update rates, the operational life is appr oximately 150 or
300 hours respectively. The optimal sensor charging temperature
is from +10 to +25° C.
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.
Numeric presentation
On the PI54 display, the Rip sensor status is displayed with
graphic symbols. The timers count the total number of minutes
the sensor has been activated (red rectangle). If only predicted
timer values exist, the timer characters are shown in grey. If the
sensor communication is lost, the graphic symbol is replaced by
the character s ***.* (in grey).
(A) = Sensor set up as sensor no.3.
(B) = A yellow rectangle indicates
that the sensor has deactivated, and
that net has been damaged. The timer
has stopped.
(C) = The timer counts how many
minutes the sensor has been activated
with a serviceable net during a tow. It
must be reset manually.
(D) = Indicator, lit for every sensor
interrogation.
(E) = Interference symbol.
(F) = A red rectangle indicates that the sensor is activated. This
is the normal position, and it means that the net is serviceable.
The timer is running.
(G) = Timer
