3. Check all cable connections and connect alternator and 
motor-generator set(s) to battery. Observe polarity. 
4. Set switch on error regulator (s) to desired output voltage range. 
5. Set the CIRCUIT SELECTOR switch on servo amplifier to 
desired mode of operation. If automatic velocity control is 
used, set VELOCITY CONTROL for desired rudder rate 
according to graph, Figure 8. 
6. Connect battery charger cable to battery. DO NOT turn — 
charger ON. CAUTION: Do not operate charger with lower 
front panel removed. 
7. Connect starting cable to alternator. 
Shore — 1. Turn TRANSMITTER and POWER and FAIL-SAFE switches ON. 
2. Press START button on top of battery charger. 
Model — 1. Wait five seconds for alternator speed to stabilize. Turn 
ALTERNATOR POWER switch ON. 
2. Wait 30 seconds for warmup of control equipment. At the end 
of this warmup, the meters on the discriminators in the demodulator 
rack should be stabilized. Depress the FAIL-SAFE HOLD switch 
on the top of the demodulator rack. 
Shore — 1. Press the STOP button on top of the battery charger and then 
and disconnect the starting cable. 
. Check operation of the rudder control circuit by operating console 
controls. Meter deflection on rudder discriminator should be 
proportional to setting of rudder control. Rudder servo should 
follow setting of console control within + 2 degrees. 
3. Check operation of propulsion control circuit(s) by operating 
lever(s) on console and observing meter deflection on appropriate 
discriminator unit. When the control lever is at the OFF position, 
the meter pointer should be deflected to the right end of the scale. 
Moving the lever to either the forward or reverse position should 
cause the meter pointer to move toward the left end of the scale. 
4. Place the propulsion levers at the OFF position. 
5. Connect the starting cable to one of the MG sets. Press the 
START button on top of the battery charger and wait 5 seconds 
for the MG set to reach operating speed. Press the STOP button 
and then remove the starting cable. 
6. When two MG sets are used, repeat the preceding step for 
starting the second unit. 
Shore — 1. Set control knobs on battery charger to positions indicated on 
charging chart mounted on battery charger according to size 
of battery in use and number of MG sets in use. 
2. Turn timer knob to 1-hour position. Cell voltage will normally 
be between 0.8 volts and 1.3 volts, depending upon state of 
charge of battery and will level off at about 1.3 volts as the 
battery approaches full charge. If charger will not come on,
