D. BATTERY CHARGER CONTROLS

NOTE: A buzz, or hum is normal when the output cables have been disconnected and the AC power cord is still connected to an electrical source (i.e. wall outlet).

Model PS-1022MA

Two switches permit Battery Type and Charge Rate selection. Switch #1 (3 Modes)

Mode 1 – Manual Position: Use for charging in 2 Amp or 10 Amp charge rates on 12 Volt batteries only. This charging must be monitored and manually stopped when the battery is charged. Overcharging will damage the battery.

Mode 2 – Automatic Position for Conventional Batteries. If you are not sure of your battery type, use the (regular) conventional setting.

Mode 3 – Automatic Position for Maintenance-free and Deep- cycle batteries.

Switch #2 (2 Charge Rate Modes)

Mode 1 – Select the 2 Amp setting to charge small 12 Volt bat- teries (31 Ah or less) or to warm larger lead-acid batteries. Mode 2 – Select 10 Amp for larger 12 Volt batteries for a faster charge.

Model PS-2100MA

Two switches permit Battery Type and Charge Rate selection. Switch #1 permits selection of either regular battery in automatic operation or Deep-cycle battery in automatic operation. If you are not sure of your battery type, use the regular battery setting. Switch #2 (4 Charge Rate Modes)

Mode 1 - Select 15 Amp, 6 Volt Manual Operation to charge medium and large size wet-cell, lead-acid, 6 Volt batteries. Do not charge small batteries such as used in motorcycles, lawn and garden equipment. Note: Manual Operation. Monitor fre- quently while charging a battery.

Mode 2 - Select the 2 Amp automatic setting to charge small 12 Volt batteries (31 Ah or less) or to warm larger lead-acid bat- teries.

Mode 3 - Select 15 Amp automatic for larger 12 Volt batteries for a faster charge.

Mode 4 - Select 100 Amp Engine Start to assist in engine crank- ing of 12 Volt systems. DO NOT use on 6 Volt systems. Use the 100 Amp Engine Start position for cranking automobiles or light trucks. Note: Use only with battery in the vehicle. This will re- duce the chance of damaging sensitive electronic equipment in the vehicle.

AMMETER

The ammeter indicates the measured amount of amperes being drawn by the battery. When you first start charging a battery, the reading will be high with the needle near 10 using the 10 Amp charge rate. As the battery charges, the needle will fall to about 4 to 5 Amps, indicating a charged battery in the manual setting. In automatic setting, when the battery is charged, the ammeter will go to zero and then will pulse frequently to monitor the bat- tery. At the 2 Amp charging rate, you will see little needle move- ment.

The percent of charge scale is intended as a visual aid to help simplify reading the state of charge of the battery. The meter is scaled for use with the 10 Amp charge rate only. For the 2 Amp charge rate use the red triangle. The percent of charge is based on current drawn by the battery. For this reason accuracy will vary with size and battery type.
