Optional Battery Temperature Sensor; Auxiliary Output; Auxiliary Battery Charge - BLUE SKY SB3000i Installation And Operation Manual

OPTIONAL BATTERY TEMPERATURE SENSOR

Install the optional battery temperature sensor as shown in Figure 4. The temperature sensor will be automatically detected by the 3000i.
➢ WARNING: Use only BSE temperature sensor p/n 930-0022-20. Other temperature sensors or electrical
connections to the temperature sensor terminals may damage the 3000i, void the limited warranty, and may
cause charge voltage to become uncontrolled. Note that temperature sensor wires are polarized RED/BLK. The
sensor will not function if installed reverse polarity. The temperature sensor lug has no electrical connection to
the sensor element may connect to any battery terminal.

AUXILIARY OUTPUT

The auxiliary output can serve one of two primary functions; 1) A 2 amp auxiliary battery charger (factory default setting), or 2) A 20 amp Low Voltage
Disconnect (LVD) load controller which may also provide variable 3) Dusk-to-Dawn lighting control. The Charge/Load functionality is selected with the
out (output) selector as described in the Charge And Load Control Settings section The Aux Out indicator will illuminate whenever the auxiliary output is
ON(*) regardless of whether an auxiliary battery or load is connected or not.
➢ CAUTION: The auxiliary output CANNOT perform both auxiliary battery charge and load/lighting functions at the
same time. DO NOT use the 20 amp Load terminal for auxiliary battery charge or the 3000i may be damaged in a
manner that voids the warranty. For clarity Figure 5 only shows additional wiring required for auxiliary output use and
assumes basic system wiring shown in Figure 4 is complete. Auxiliary output compression terminals accept #2212
AWG wire and are to be tightened to 6 in-lb (0.67 nm).

➢ (*)The LOAD indicator light will be ON whenever power is available at the Load and Auxiliary Battery Charge
terminals.
1) AUXILIARY BATTERY CHARGE – "out" setup selector set to "ch9" (charge)
The auxiliary charge function is used to charge an auxiliary battery of the same voltage as the primary battery. Its purpose is not to charge an auxiliary
battery that is regularly discharged but rather to maintain a battery that is infrequently used such as the engine start battery in a Motorhome. The
primary battery is first priority and the auxiliary battery is second priority. If the primary battery is charging in Absorption or Float, meaning that it does
not need all available solar power, up to 2 amps is diverted to the auxiliary battery at the same charge voltage. Auxiliary battery charge is disabled during
Bulk or Equalization. Use 14 awg wire to minimize voltage drop and 25 amp maximum over current protection. Auxiliary battery negative must connect
to primary battery negative.
