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
90
o
C.
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.
3.3 TIMER
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).
