3.1.5. MODES:
3.1.5.1. Main and topping for Constant Current
3.1.5.2. Constant Voltage
3.1.5.3. Peak Voltage.
3.1.6. TIMER:
3.1.6.1. 1 to 9 hours for MAIN charge time and 1 to 60 hours for TOTAL time.
3.1.6.2. Time can also be programmed in minutes by selecting the FAST mode
in the TIMER SPEED selector switch (Front Panel).
3.1.6.3. NOTE 1: Topping charge time equals the total charge time minus the
main charge time (TOTAL = MAIN + TOP).
3.1.6.4. NOTE 2: Newer instruments may have a new version of the Timer
(Identified by an external Timer Speed Switch) that has a maximum of
79 (hours or minutes) in Total Time.
3.1.7. OVERTEMP PROTECTION:
3.1.7.1. Four thermistors on the TEMP-PLATE measure the battery
temperature.
3.1.7.2. The charge is terminated when the surface temperature of the TEMP-
PLATE reaches 39
o
C (102
o
F).
3.1.8. OVER/UNDER CURRENT PROTECTION:
3.1.8.1. A Monitor circuit continuously compares the actual charge current
with the programmed value.
3.1.8.2. Operation is terminated if they differ by more than 1 AMP.
3.1.9. OVERVOLTAGE PROTECTION:
3.1.9.1. Programmable, in accordance with the number of cells selected, at the
equivalent of 1.75 volts/cell (TOLERANCE: ±1%, ±0.1V).
3.1.9.2. Absolute maximum internal limit set at 85 VOLTS.
3.1.9.3. NOTE: Does not apply in the Float and Peak voltage modes. (Voltage
is controlled in those modes).
3.1.10. REVERSE POLARITY PROTECTION:
3.1.10.1. Operation of the unit is inhibited for reverse voltages greater than 0.5
VOLTS.
3.1.11. FUSING:
3.1.11.1. Aircraft type current limiter, ANL-60 (slow).
3.1.12. AC LINE CURRENT:
