4/10/20/40A AMP (Charge Rate Selector) (Step 2) allows the user to select the charge rate based on battery size. This selection and the actual battery charge rate are monitored by the microprocessor. The charger will stop charging if the rate is too fast or too slow for the battery size or condition.

110 AMP Engine Start places the charger in an engine start sequence. This button will not be activated unless the charger is in the 40 amp charge mode; set the 4/10/20/40 amp button to 40 amps first to activate this button.

Battery Recondition is an automatic mode that, once started, continues for 24 hours and then stops. A series of electrical pulses breaks the crystalline form of lead sulfate to return these chemicals into useful battery electrolytes. More than 24 hours may be needed to restore. Periodic reconditioning is recommended to maintain a battery's optimum performance. However, if 5 cycles does not improve battery performance, discontinue and recycle the battery.

Battery Voltage (Alternator Voltage Check) is a quick check that measures the battery voltage. This check is repeated at various electrical load levels and the tests allow the user to determine if the alternator can keep up with the loads.

INDICATOR:

Large (.375”) 3-Character Digital Display in the upper left of the control panel indicates the various conditions and/or status codes:

Status Codes are described in the following chart and on the back of charger.

AC POWER INDICATOR - When connected to an AC outlet, digital display shows circulating pattern to indicate power is on. Disconnect charger after use.

FAULT CODES

 

 

 

F01

INTERNAL SHORTED CELL BATTERY - Cannot be charged. Have battery checked by certified auto service center.

 

EXCESSIVE LOAD ON BATTERY WHILE CHARGING - Check load.

 

F02

BAD BATTERY CONNECTION - Check battery connection.

 

BATTERY VOLTAGE TOO LOW TO ACCEPT CHARGE - Have battery checked by certified auto service center.

 

F03

INTERNAL OPEN CELL - Have battery checked by certified auto service center.

 

SULFATED CONDITION - Battery needs to be reconditioned. See manual.

 

F04

OVERTIME CONDITION - Battery will not accept a charge after 18 hours of continuous charging. Battery may have

 

internal damage. Have battery checked by certified auto center.

 

BATTERY CHARGE RATE IS SET TOO LOW - Set charger to higher charge rate. See manual.

 

F05

OVERHEATED CONDITION - Disconnect charger and allow to cool for 30 min., check for ample ventilation.

 

F06

REVERSE POLARITY

 

F07

ALTERNATOR OUTPUT IS OUT OF TYPICAL OPERATION RANGE

 

OPERATION CODES

 

BATTERY RECONDITIONING - (The letters DES will display for the first 3 seconds.)

000

ALTERNATOR VOLTAGE CHECK

CHARGER STANDBY

FUL

BATTERY FULLY CHARGED

CONTROL PANEL LED INDICATORS:

WET — lights when battery type selector is on WET battery type GEL — lights when battery type selector is on GEL battery type AGM — lights when battery type selector is on AGM battery type.

Float Charge — lights when automatic charge monitoring is active. This feature allows a battery to maintain its charge over long periods of non-use. If there is any loss of power to the charger once power is restored, charger will automatically return to the default settings. Battery selector type would be “gel”.

Battery Voltage — lights when battery voltage is displayed.

Alternator Good — lights when load or no load checks show the alternator is keeping up with the electrical load. Equalize — a recessed button used to start the equalize process.

OPERATING INSTRUCTIONS

Ensure that all installation and operating instructions and safety precautions are understood and carefully followed by anyone installing or using the charger. Follow the steps outlined in the “Important Safety Instructions” section of this manual.
