A. General
As an option to using Alkaline Manqanese Dioxide batteries, the PSLT is supplied with two battery
packs containing NiMH rechargeable batteries. Prior to use, they must be fully charged using the
Accumax C512MD-01 Battery Charger provided as part of the 'Micro Leak' Case Assembly. The
C512MD-01 is a 2-channel microcontroller-based equipment which discharges and recharges
batteries automatically to ensure that they operate at full capacity and that the risk of damage due
either to the memory effect or to over -charging is reduced.
Safety features include the following:
1) Visual Warning and Power Cut-Out for Reversed Battery Connection.
2) Current Limiting and Power Cut-Out for a Shorted Output.
3) Power Cut-Out/Time-Out in the event of a Charge Control Error.
4) Thermal Limit Monitor.
5) 3.15A Slow Blow Fuse protection for the Power Supply.
6) 7.5A Fused Output.
B. Applying Power to the Charger
The C512MD-01 may be powered from any a.c. mains supply within the range 100 to 253V
a.c., 50 to 60Hz and no pre-selection of the supply to be used is necessary. Power is applied
to the charger as follows:
1) Connect the charger to the mains supply using the standard IEC mains lead supplied.
2) On the charger, press the rear panel rocker switch to the ON position.
The front panel power indicator (green LED) should illuminate.
C. Charging Batteries
CAUTION:
ONCE CHARGING HAS COMMENCED, IT IS ESSENTIAL NOT TO
DISCONNECT THE BATTERY PACKS FROM THE CHARGER UNTIL
CHARGING IS COMPLETE AND BOTH LED ARE ILLUMINATED.
FAILURE TO COMPLY MAY RESULT IN DAMAGE TO THE GAS
GAUGE CIRCUITRY.
1) When power is applied to the unit, the charger samples each of the channels in order to
detect the presence of a battery pack.
2) Connect the first rechargeable battery pack to the Channel 1 connector on the charger, and
the second battery pack to the Channel 2 connector. The front panel yellow LED associated
with each channel should start to blink, indicating that the presence of the battery packs has
been detected.
3) The battery pack connected to Channel 1 is discharged first. When completely discharged,
the charger automatically commences the charging cycle. On completion, the Channel 1
indication will stop blinking and remain permanently illuminated.
4) The discharging and charging 01f the second battery pack then commences. When the LED
for both channels are permanently illuminated the batteries are fully charged and ready for
use.
