Indicators
(A) =Mains:12to32Vdc
(B) = Fuel meter. The number of LEDs illuminated shows the
current charging status. A complete charging cycle is indicated
with all “full” battery. Charging:
Fast:Fastflash
Normal: Slow flash
Trickle: On, off every 4 second
(C) = Battery temperature indicators during fast charging:
Green: Battery temperature between +5 and +40°C. Fast
charge is enabled.
Green and Blue: Battery temperature between 0 and +5°C.
Fast charge is disabled, normal charge is used.
Green and Red: Battery temperature between +40 and
+50°C. Fast charg disabled, normal charge is used.
Blue: Battery temperature is below 0°C. No charging takes
place.
Red: Battery temperature is above +50°C. No charging takes
place.
Warning: Charging a sensor at sub-zero temperature might
develop explosive gases r epresenting a potential
danger. Simrad assumes no liability for improper
charging, o r the use of other chargers than those
approved by Simrad.
Automatic configuration
The charger communicates with the sensor at regular intervals.
The fast charge cycle is controlled by data exchanged between
the PI sensor and the charger, and a series of safety mechanisms
controls the t ermination of the fast charging current.
The PS sensors do not communicate with the charger. A
constant charge current of 58 mA is then set up by the charger
regardless of the battery temperature.
Typical sensor (PI Depth)
(A) = Negative charging / fastening lug
(B) = Positive charging / fastening lug
(C) = Communication link
(D) = Location of sensor lamp
(E) = Water switch sensor
(F) = Water pressur e sensor
