GENERAL DESCRIPTION: The high frequency, SuperSmart (golf-cart style) battery charger is a high frequency switching power converter that has a true DC output at a maximum power level of approximately 600 watts for all models except the 12V20A which is a 300 watt unit. The most common output voltage and current configurations are defined as models in the title block. Also, a variety of software configurations are available: Standard; Sealed, VRLA, GRT, AGM (Hawker/Optima); and GEL.

OUTPUT CABLE CONNECTIONS: Thebattery charger is equipped with separate output leads for the positive and negative polarity connections. The models with Sealed GRT/AGM (Hawker/Optima) software have a third, yellow wire that is a voltage sense connection. The yellow and red wires should both be connected together at the positive terminal of the battery. Also, on the Sealed GRT/AGM models, there is a small, momentary, push-button switch to select between software options. The standard output cable configuration does not include a quick disconnect harness.

STATUS INDICATOR LIGHTS: The following describes the operation of the status indicator lights:

AMBER (Yellow) - When the amber light is on, the battery charger is in the process of fully charging the battery. In order to properly charge large capacity batteries, the charger may remain in this mode for several hours or even days.

AMBER (Yellow) FLASHING(Hawker/Optima [Sealed, GRT, AGM] Models only) - When the amber light is flashing, the charger is in the "Monthly" mode of charging. This is a fixed length absorption charge prior to float/maintenance. To engage the monthly charge mode, depress and hold the charge selector button for 3 to 5 seconds immediately after applying AC power to the charger.

GREEN FLASHING(Standard Models only) - When the green light is flashing, and the amber light is on, the battery is greater than 80% charged and may be removed from the charger and used if necessary. Leave the battery on charge until the green light is solid whenever possible.

GREEN - When the green light is lit, the battery charger is in the storage mode of charge. In this mode the charger will maintain the battery at full charge. If the battery becomes partially discharged due to an external current draw or excessive internal battery losses, the charger will automatically switch itself back to the charge mode of operation.

RED - When the red light is on, there is a malfunction in the charger.

RED FLASHING(Hawker/Optima [Sealed, GRT, AGM] Models only) - When the red light is flashing, the battery has either not been connected to the charger, or it has been connected improperly.

SPECIAL TROUBLESHOOTING INFORMATION:

1)NONE OF THE CHARGER STATUS INDICATOR LIGHTS TURN ON:

a)Disconnect the charger AC power plug from the AC outlet and recheck that the DC output ring terminals are connected to the correct polarity battery terminals and that they are making a clean, tight connection.

b)Check to make sure that the AC outlet is supplying power by plugging in another appliance like a lamp, or check the outlet voltage with a voltmeter.

2)THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT (GREEN LIGHT) GOES ON IMMEDIATELY WHEN CHARGING A BATTERY KNOWN TO BE DISCHARGED:

a)The battery may be defective. Take the battery to the dealer to be tested.

b)The electrical connections between the charger and the battery may not be completely secured.

3)AFTER THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT (GREEN LIGHT) HAS BEEN ON, AND THE AC POWER IS REMOVED FROM THE CHARGER AND THEN IMMEDIATELY RECONNECTED, IT SEEMS TO TAKE TOO MUCH TIME FOR THE GREEN LIGHT TO COME ON AGAIN.

a)This is NORMAL OPERATION for the High Frequency Golf Cart Charger.

b)Whenever AC power is removed from the charger, including momentary AC power outages, the charge cycle resets. Therefore, depending on the software version, several hours may elapse before the green light comes on.

4)AFTER THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT (GREEN LIGHT) HAS BEEN ON, THE AMBER LIGHT COMES ON.

a)This is NORMAL OPERATION for the High Frequency Golf Cart Charger.

b)There has been a momentary AC power outage that reset the charge cycle.

c)There is some other load or appliance drawing power from the battery. When the battery voltage drops below 12.0V to 12.5V, on 12 volt models, the charge cycle resets.

ADDITIONAL TROUBLESHOOTING INFORMATION: If the green status indicator light turns almost immediately after beginning to charge a battery that is known to be discharged, then check the output fuse. The only function that the output fuse performs is to protect the charger circuitry from a reverse polarity connection. Replacement: 25 Amp (or 30 Amp), 125 Volt, Cartridge, 0.25 inch by 1.25 inch, Ceramic, Fast Blow, for example: Bussman PN: ABC-25 or ABC-30. Alternate: Littelfuse PNs 314-025 (Deltran PN 201-0037) or 314-030, Cartridge Style, Ceramic Body, 3AB, Fast Acting Type, Rated at 25 or 30 Amps, respectively.

ADDITIONAL CHARGE ALGORITHM TIMING INFORMATION: I

18 hour overall timer IS implemented in all Standard and GEL golf cart chargers.

18 hour overall timer IS NOT implemented in AGM/GRT golf cart chargers.

High Frequency, SuperSmart Chargers: EMERGENCY VEHICLE Model: 12V20A

GENERAL DESCRIPTION: The Emergency Vehicle Charger isone of the model variants of the high frequency, SuperSmart, golf-cart style battery charger. It is a high frequency switching power converter that has a true DC output at a maximum power level of approximately 300 watts.

OUTPUT CABLE CONNECTIONS: Thebattery charger is equipped with a terminal block for direct connections to AC and DC power.

STATUS INDICATOR LIGHTS: The indicator lights are mounted on a remote panel: The remote panel is marked as follows: From top to bottom: BATTERY STATUS, then the green light, FULL CHARGE, then the red light, and finally BATTERY LOW WHEN FLASHING. The following describes the operation of the status indicator lights:

GREEN FLASHING - When the green light is flashing, the charger is charging the battery normally, in either the bulk or absorption mode. There is no separate indication for those two sequential modes.

RED FLASHING - When the red light is flashing, the battery voltage has dropped to below 11.75 VDC. At this time, the operator should plug the charger into the AC power receptacle. The flashing red indication will only be given when no AC power is applied to the charger.

TROUBLESHOOTING INFORMATION: Similar to that for the HF Golf Cart chargers, except for the differences in status indicator light operation.

Table 5 Spec Sheet: HF SuperSmart Charger (36V, 48V AGM)

High Frequency SuperSmart® (Golf Cart) 12V20A Models:

12V20A STANDARD:

Stage 1) Bulk Charge: Amber Light On, Constant Current = 20.0 Amps, Transition to Stage 2, Absorption Charge when battery voltage reaches 14.5 VDC.

Stage 2) Absorption Charge: Amber Light On, Absorption Voltage = 14.5 VDC Transition to Float Charge when battery charging current drops below 3.0 amps, or when 18 hours has elapsed from the time the charger was turned on.

Stage 3) There is no Equalization Charge, Go directly to stage 4.

Stage 4) Float Charge: Amber Light Off, Green Light On. Float Voltage = 13.2 VDC. If an external load is applied to the battery while the charger is in stage 4, Float Charge, and if the battery voltage drops below a range between 12.0 to 12.5 VDC, then the charge cycle restarts.

Figure 1 Charging Graph: HF SuperSmart® 12V20A STD

12V20A Sealed/VRLA/GRT/AGM (Hawker/Optima): Adaptive 4-Step:

Stage 1) Bulk Charge: Amber Light On, Constant Current = 20.0 Amps, Transition to Stage 2, Absorption when battery voltage reaches 14.9 VDC.

Stage 2) Absorption Charge: Amber Light On, Absorption Voltage = 14.9 VDC. Set Absorption Timer when charge current drops to 18 amps. This is approximately the same time that the voltage reaches 14.9 VDC. The Absorption Timer length is computed as a function of the time it takes to complete Bulk Charge. Absorption Charge Time = 1.5 x Bulk Charge Time. Transition to Equalization Charge when Absorption Timer resets.

Stage 3) Equalization Charge: Amber Light On, Equalization Voltage Limit = 15.6 VDC. Set Equalization Timer equal to 0.5 x Bulk Charge Time. Charge current is constant at 2 amps until the battery reaches the equalization voltage limit. Then the voltage is held constant at 15.6 VDC and the current gradually decreases. Transition to Float Charge when Equalization Timer resets.

Stage 4) Float Charge: Amber Light Off, Green Light On. Float Voltage = 13.6 VDC. If an external load is applied to the battery while the charger is in stage 4, Float Charge, and if the battery voltage drops below a range between 12.0 to 12.5 VDC, then the charge cycle restarts.

Figure 2 Charging Graph: HF SuperSmart® 12V20A AGM

12V20A Sealed/VRLA/GRT/AGM (Hawker/Optima): MONTHLY Charge Mode:

This charge mode is activated by holding in the pushbutton switch for 5 seconds at the beginning of the charge cycle.

Stage 1) Bulk Charge: Amber Light On, Constant Current = 20.0 Amps, Transition to Stage 2, Absorption when battery voltage reaches 14.9 VDC.

Stage 2) Absorption Charge: Amber Light On, Green Light Flashing, Absorption Voltage = 14.9 VDC Transition to Float Charge 16 hours after entering stage 2.

Stage 3) There is no Equalization Charge, Go directly to stage 4.
