SECTION I GENERAL INFORMATION 1 .1 INTRODUCTION The solid state constant voltage battery charger (Figure 1), can be used for charging, or maintaining at a constant state of charge, both Ni-Cad or lead acid batteries of various cell and voltage configurations. Two models are available with outputs of either 0-19 VDC or 16-30 VDC. The components are mounted in a three piece U-shaped chassis with an easily removable cover for access to the interior. There is a single adjustment control for setting the output and a 0-30 amp meter. These, along with the input and output terminals are located on the front of the unit. A pilot light is also provided which indicates if the unit is on or off.

INITIAL CHECKS
Check for the following to ensure compatibility with the charger operating requirements.
2 .2
a.
AC input voltage, phase an:i frequency of power source.
b.
That the charger is the correct size for the applicatia:i.
c.
If correct, proceed with the set-up instructions.
.SE!'- UP P ROCE DURE .S a.
Ccnnect the proper AC input to the battery charger. Ca:inect the charger's DC termirals directly to the normal load (eliminating the battery).
b.
Check the battery chart en the top of the charger for the correct voltage setting for the battery type used ( refer to Table 1). Table 1.

d.
Turn the AC power 01 ar:rl turn the powerstat (screwdriver slot) clockwise until the voltage agrees with the battery chart for the battery type ar:rl number of cells used.
e.
This is the set point. Turn the AC 1:x>ver off and disconnect the load circuit from the charger ar:rl tighten charger set screw to hold the powerstat setting.
The battery charger is now properly set ar:rl needs no futher adjustments. After following the set-up procedure the battery charger should then be connected directly to the battery terminals ar:rl the battery output terminals should then be connected directly to the proper load terminals. The battery in this way provides a good filter for the system. The charger may be either mounted m a backboard or set freely m a shelf. Encugh room should be allowed for proper ventilation.

SECTION 111 FUNCTIONAL OPERATION
3.1 DESCRIPTION OF OPERATION The normal operation of the battery charger will be to supply the fixed load and fluctuating loads as they may occur in the system. The set-up procedure when done properly will keep the batteriEB charged and supply overloads up to the chargers' maximum output. The charger is capable of supplying 15 amperes continuously and is designed to have current limiting of approximately 25 amperes maximum, depending on the voltage setting of the powerstat. The charger is also protected for passible over temperature operation with an autanatic type thermal overload. If this condition occurs, the charger will cycle "on" and "off'' as thermal overload protector heats and cools and protects the charger in case of reverse polarity connection. As the batteries become charged, the battery charger will return to its normal operation. No new voltage setting of the charger is required. SECTION IV MAINTENANCE 4. 1
SERVICE PROCEDURE (See Figure 2) a.
Check AC power supply (plug, cord, fuse, etc.).
b.
Check for visible physical damage.
c•
Check OC out put : 1.
If circuit breaker trips, check for reverse polarity of batteriEB.
2.
Check for defective rectifier.
d.
Check parts - ammeter, rectifier, transformer, condenser, for tight connections •
e.
Check condition of batteries: 1.
Specific gravity (before and after charge).
2.
Volts/cell (before and after charge).
3. OC current (at start and finish of charge).
