1-1 General Safety Precautions

WARNING Read following safety instructions carefully before installation.






Save these instructions of PANcharge1k battery charger and batteries. This manual contains
important safety and operating instructions.
Operate PANcharge1k in a well-ventilated and dry area. Do not exposed to rain or snow.
To reduce a risk of fire, do not cover or obstruct the ventilation enclosure.
To avoid a risk of fire and electric shocks, do not operate charger with damaged or undersized
cords.
To avoid the risk of fire and electric shocks, do not disassemble charger.

NOTE

Warranty not valid once PANcharge1k is disassembled.

To reduce the risk of electric shock, follow the steps below before wiring, maintenance and cleaning.
Turn AC power switch off.
Remove AC power cord from the charger.
First remove the black charging clip from the battery then the red one.

By covering charging clips to avoid short circuit of charging terminal while turning switch ON.
Ground the earth cord with the power cord to reduce the risk of electric shock, to protect from external
radio interference and not to radiate harmful emissions. The earth cord is connecting with the charger’s
chassis.
To avoid the risk of electric shock and fire, adjust the AC power switch in the rear of the charger to thesame voltage as the input one. Plug the proper power cord to the plug-in. NEVER input 230Vac with the
115Vac setting. It may lead to a fire, electric shock, or charger damage.

NOTE

Once PANcharge1k is opened or modified, DENRYO CO., LTD. has theright not to provide warranty service.

94. Operation
PANcharge1k is a charging voltage adjustable battery charger. The charging voltage is able to be switchedin accordance with the battery voltage of 12V, 24V, 36V or 48V by the battery voltage setting switch on the
charger.

4-1. 3 Stage Charging
PANcharge1k charges by the 3 stage charging: bulk, absorption charging and floating charging. In bulk
charging stage, PANcharge1k outputs and charges by a constant current. In absorption charging stage,battery voltage is constant but the current is decreasing, and battery generates gas.
In the last stage of floating charging, charger charges with constant low voltage, maintains the battery at
100% state of charge. If the battery does not connect to any load, it is normally charged with a very low
current.

4-2. Operation and LED Indicators
Step 1. Make sure the AC power voltage switch is correct set.
Step 2. Make sure the AC power switch is OFF and check the charging voltage setting is correct.
Step 3. Connect positive charging clip (red) to positive terminal of battery.
Step 4. Connect negative charging clip (black) to negative terminal of battery.
Step 5. Press I on the AC power switch to turn charger ON.
Step 6. All the LED light up for 2 seconds. Afterward, red LED lights up for 5 seconds. The
rectangle LED indicates the set charging voltage.
Step 7. Charging begins. The relay in the charger turns ON. A clink sound is normal.
Step 8. Yellow round LED: light up constantly
The LED lights yellow for 25 seconds means charging just begins and is charging slowly. At thetime, rectangle LED all light up initially, and turn to display the percentage of battery capacity
charged by the amount it lights.
Step 9. Yellow round LED: flash slowly
The LED turns to flash yellow slowly means it is charging in a constant current, the bulk charging
stage. At the time, the numbers rectangle LED light up increases with the capacity has been
charged.
Step 10. Yellow round LED: flash quickly
The LED turns to flash yellow quickly means it is charging in a constant voltage, the absorption
charging stage. At the time, the numbers rectangle LED light up increases with the capacity has
been charged.
Step 11. Yellow round LED: flash very quickly
The LED turns to flash yellow more quickly means it is about to turn to floating charging stagesoon.
Step 12. Green round LED: flash slowly
The LED turn to green means it has turned to the floating charging stage. Battery is full charged.
Step 13. Green round LED: flash quickly
The LED turn to flash green quickly means it is in the floating charging stage and charging
current is beyond 0.5A.
Step 14. Battery charging is finished. Follow steps below to remove the battery.
Turn charger OFF. The relay in the charger turns OFF. A clink sound is normal.



Remove the black charging clip from battery, then remove the red one.

4-4. Protection

Short-circuit protection: It will not be damaged even the output terminal is short-circuited.



Reverse connection protection: It will not be damaged even battery is reversely connected.

Over temperature protection: Fan spins when charger internal temperature rises above a certain
level, and switches to strong or weak automatically depending on the temperature. Fan stops when
the temperature drops beyond a certain level. However, once the temperature rises higher than thegeneral level, LED turns to error display. Leave it for a while and wait for the temperature drops to thenormal level; charger recovers and charging restarts.

Input protection: An abnormal current flow in internal charger because of the charge itself or otherexternal factors, the protection works by melting the fuse of the input power.

 Output protection: Due to the trouble of charger itself or other external factors, abnormal current
flows between the charger and battery. The fuse gets melt to protect the charger and safety.
