User manual SIMRAD PI CHARGER QUICK REFERENCE GUIDE REV D

[. . . ] Quick reference guide Simrad PI Charger Purpose Daily operation Indicators The Simrad PI Charger is an intelligent battery charger for fast and secure charging of the PI sensors. The charger will automatically set up the correct charging current depending on the sensor type and the battery temperature. [. . . ] If the sensor can not be fast charged, the charger will not display the battery temperature, and the temperature LED will be dark. 3) Observe the charge times and temperature limitations: Fast charge: First approximately one hour for 70% battery capacity, then approximately three hours to reach 100% capacity. Once fully charged, a constant trickle charge will compensate for self discharging. Note that fast charging applies to PI sensors only!Normal charge: 16 hours for full battery capacity. This mode applies for charging outside specified temperature range, and for all PS sensors. Charging temperature: For best results, keep the ambient temperature between +10 and +25°C. Do not charge sensors in temperatures above +50°C or below 0°C! (A) = 12 to 32 Vdc connected (B) = "Fuel meter", the number of LEDs illuminated shows the current charging status. A complete charging cycle is indicated with all "full" battery. Charging is indicated as follows: Fast: Fast flash Normal: Slow flash Trickle: On, off every 4 second (C) = Battery temperature indicators during fast charging of PI sensors: A Green: Battery temperature between +5 and +40°C. Green and Blue: Battery B temperature between 0 and +5°C. Fast charge is disabled, normal charge is used. [. . . ] 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.
