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. [. . . ] Once connected, the charger will identify whether the sensor connected can be fast charged or not. The battery temperature will always be monitored for a fast charging sensor. 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. 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 constant charge current of 58 mA is then set up by the charger regardless of the battery temperature.
