WARNING!

Please read the safety instructions carefully before using the charger.

4. Important safety guidelines and instructions Please read the following instructions carefully to prevent personal injury or damage to charger. If the charger is not installed properly, it might cause hazard. Before you clean or maintain the charger, you must disconnect AC input.

Battery precautions.

Please follow these instructions marked on the battery to reduce the risk of battery explosion

Do not produce sparks or flames around the battery and engine Do not charge those batteries that are not on recommended list such as nickel

cadmium (NiCad), nickel metal hydride (Hi-MH) batteries and so on. Other types of batteries might burst and cause personal injury.

Do not charge a frozen battery Do not work nearby a lead-acid battery. The battery may cause explosive

gases during operation. When you install the charger around the explosive gases, it is necessary to

take safety precautions Do not place the charger under or on the battery. Gas or fluid from the battery

will corrode and damage the charger. Place the charger as far as possible from batteries in a distance of DC cable

length.

Precautions of operating the charger

Do not operate the charger in a confined space. Do not place the charger in a humid environment. When it is installed on a ship

or yacht, make sure it won’t be splashed by water. Do not block the vent. There should be a space at least 6 inches from the vent. It’s strongly recommended to install and operate the charger by a licensed

electrician, especially installing in a caravan or a yacht. Make sure that the socket is connected to the ground. PPT is connected to the

ground through the AC cable and the socket. If the cable is damaged, do not operate the charger.

Pay attention!

Be careful to setting the battery charger. Do not set the battery type Li-Fe if you want to charge the lead-acid battery.

Otherwise your battery will be damaged.

5.3. Functional settings--Press the button “Function/Confirm” for 3~ 5 seconds to enter the setting steps of charging: Step 1---Batteries types setting (Li-Fe, AGM, GEL—voltage settings), after selecting the type of battery, press the button “Display mode/Confirm” to confirm setting. Step 2---Charging current setting (select current to charge), after setting the current, press the button “Display mode/Confirm” to confirm setting. Step 3---Charging timer setting (9 ~ 999 minutes) for timer setting, one press button “Function/Confirm” will reduce 10 minutes each. Long press button ”Function/Confirm” 2 seconds above will speedy reduce, can be recycled setting). After setting timer, press the button “Display mode/Confirm” to confirm setting. NOTE : Setting the unit to 999T will disable the timer function of the charger and enable the charger to be used in automatic function. Each step of settings can see the digital number and LED display on the front panel.

5.4. Connect the charger to the battery. Do not reverse the polarity. During charging, you can press the button “Display mode/Confirm” to monitor the details (battery voltage, charging current, Battery charged percentage, current/hour, charging Time).

5.5. Pressing the” Battery spec./Repair” for 3 ~ 5 second if the Battery needs to be repaired. It will automatically goes into charging stage after 10 minutes repairing time.

5.6. PPT-580 started car engine function: when you needed to start the car engine, connecting the AC input and output cable to the battery. Power on and press "FUNCTION" button about 3 to 5 seconds to enter the function setting mode. Pressing “Display mode” button after the display showed 14.2V.

T2: Pulse

When battery voltage is higher than 12V, PPT will charge battery with 100% of setting current by pulse charging for 10 minutes.

T3: Bulk (Constant current)

After 10 minutes of pulse charging, PPT will charge battery with constant 100% of setting current till battery voltage reaches 14.4V.

T4: Absorption (Constant voltage)

PPT will continue to charge battery with 14.4V until charging current drops to 10% of setting current.

T5: Analysis

PPT will stop charging in Analysis stage. Till battery voltage drops to 13.4V.

T6: Recondition

PPT will start to charge with 50% of setting current. When battery voltage reaches 15.4V, PPT will decrease charging current till 10% of setting current.

T7: Float

PPT will stop charging till battery voltage drops to 13.4V. Then PPT start to charge again with constant 13.8V till the current drops to 10% of setting charging current.

T8: Maintain

When battery voltage is between 13.4V~14.4V, PPT will maintain battery 98%~100% full.

9.3. Protections:

Reverse polarity protection:

When the positive and negative polarity is reversed, PPT will not operate. It shows "REVE" on digital LED display.

Wrong specification protection:

When the setting is not correct, PPT will not work. For example, if you selected 6V to connect 12V battery, it would show “HI-U” on digital LED display. If you selected 24V to connect 12V battery, it would show “LO-U” on digital LED display.

Over temperature protection

If PPT was running in an extreme hot environment, Or PPT has been running for a long time at full load. It would stop running at 65℃ and show "HI-t" on digital LED display.

The 3 color LED shows red as Faulty if it was under any protection.

Problems Possible Causes Solutions

Turn the power switch,

on but PPT does not

work

Input voltage is not normal

Check the AC voltage is during

85VAC~260VAC then plug again and

reboot

AC cable may damage Change another good AC cable

AC cable is not connected

well to socket Check and plug again

Connect the battery, but

PPT does not charge,

LED lights red

Battery polarity may be

reversed Connect the correct polarity

Battery settings is not set

correctly

Check the battery specifications then set

again.

Overheating protection

Check if there is something that blocks

the vent, remove it or replace PPT to

another location with good ventilation

Battery voltage is too high or

too low

Check if the battery is damaged, replace

good batteries

Battery is unable to be

fully charged

Charging time is set too

short Reset the charging time

Charge current is too small Please check battery capacity then reset

an appropriate charging current

Fan does not run

Temperature does not reach For consecrating energy, when PPT is

working at small load, fan will not run

Fan broken

Fans has its life expectancy, if PPT has

been using for a long time, fan could be

broken, please contact local dealer or

change it by a license electrician

12. Maintenance and Warranty：

If the charger is being used normally, maintenance is not required. Just wipe the exterior with a damp cloth if dirty. Clean the dust off the fan vent when needed. Make sure when you clean it, the AC cable is unplugged. Comes complete with 1 year RTB (Return To Base) warranty.
