Once installed and put to use, the sensor will automatically be
switched on once the waterswitch is activated. After an initial
startup, the sensor start s transmission of the detector wire (F)
status (in or out). When the sensor is not in use, check that the
sensor lamp (D) is not flashing from time to time, as this
indicaties 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 sensor must be charged
approximately every 60 hours. Used with Normal or Slow
update rates, the operational life is approximately 250 or 450
hours respectively. When the sensor is configured as an FA701,
the operational time is approximately 250 hours. 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 sensor charging documentation.
Catch presentation
On the PI54 display, the Catch 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.2.
(B) = Sensor in standby. The timer
has stopped.
(C) = The timer counts how many
minutes the sensor has been activated
during a tow. It must be reset
manually.
(D) = Indicator, lit for every sensor
interrogation.
(E) = Interference symbol.
(F) = Sensor set up as sensor no.3.
(G) = The sensor has been activated.
The timer starts. An audible alarm
may be enabled.
(H) = The timer shows how many
minutes the sensor has been
activated.
