Precision Trading 60 R3.0 operating instructions Timer, Terminal Voltage, Overheat Protection

Operator Manual, Supercharger 60 R3.0

3.2.6.TERMINAL VOLTAGE:

3.2.6.1.Programmable, in accordance with the number of cells selected, at the equivalent of 1 VOLT/cell.

3.2.6.2.TOLERANCE: ±1% ±0.1 VOLT.

3.2.6.3.NOTE 1: Due to cable/connector losses the voltage registered by the Charger-Analyzer will be lower than the actual battery voltage (up to 0.2V depending on current).

3.2.6.4.NOTE 2: Terminal voltage is ignored in the full discharge mode.

3.2.7.OVERHEAT PROTECTION:

3.2.7.1.Two thermistors measure the temperature of the bank of discharge transistors.

3.2.7.2.Operation is terminated if the transistors surface temperature exceeds 90oC.

3.2.8.OVER/UNDER CURRENT PROTECTION:

3.2.8.1.A Monitor circuit continuously compares the actual discharge current with the programmed value

3.2.8.2.Operation is terminated if they differ by more than 1 AMP.

3.2.8.3.NOTE: Undercurrent monitoring is disabled in the full discharge mode for battery voltages below 2.5V.

3.2.9.REVERSE POLARITY PROTECTION:

3.2.9.1.Operation of the unit is inhibited for reverse voltages greater than 0.5V

3.2.10.FUSING:

3.2.10.1.Aircraft type current limiter, ANN-80(fast).

3.2.10.2.NOTE: The type of limiter and current rating are critical for proper protection of the discharge circuits. Failure to replace the discharge current limiter with the proper type/value may result in catastrophic damage of the load banks.

3.3TIMER

3.3.1.TIME BASE:

3.3.1.1.Microprocessor Controlled

3.3.2.MODES:

3.3.2.1.NORMAL: Timer advances at the rate of one count per minute (HH:MM).

3.3.2.2.FAST: Timer advances at the rate of one count per second (MM:SS).

3.3.2.3.TEST: Timer advances at the rate of 60 counts per second (SS:SS/60).
