Digital Display Port: The Digital Display Port has dual functions. It can be used for optional external display or for PC interface. Use for external display The interface port is used for connecting an optional external display. The external display (sold separately) has identical functions to the built-in unit display. Use for PC interface • A KISAE Abso Charger PC Interface Kit (sold separately) is available and is used to connect between the port and the PC.
Battery Bank Size Recommendation: The battery charging current rating is based on the battery size. Each battery bank should meet the minimum Ah rating as shown. If a smaller size battery bank is used, set the current rating to lower value to match with the battery bank size. Normally, the minimum battery bank capacity is based on twice the charger current rating.
DC Output Wiring: WARNING: The DC wiring used must be of appropriate size. An individual over-current protection device usually within 7 inches (17.8cm) of each battery bank is required. A DC disconnect switch is also recommended. Both devices must be rated for DC voltage and current and be rated to withstand the short circuit current available from the connected battery bank. Both devices must match with the size of the DC wiring.
Note: Do not use COM_2 on the Remote Display. For AC2430 model: The 24V model is capable to connect in parallel. Connect two AC2430 in parallel will provide a total of 24V 60A charging current. Use on single AC2430 charger • To install the optional Remote Display in a specific location, a 6 pin standard RJ12 cable (maximum length 25 ft) is required. • Install the standard RJ12 cable in your desired location.
Test the Charger Connection: • Switch AC branch breaker switch to ON. • The display will turn on. Pressing the ‘INFO’ key will toggle the display to show the factory default setting. The charger is now ready to use. 5. UNIT OPERATION Understanding the Charging Mechanism • The charger is a three bank battery charger that is capable of charging a maximum of three battery banks. • The charger is designed to have Bank 1 charge the main battery bank.
Understanding the Digital Display Function with no AC Input: Press and hold the ‘INFO’ key for 3 seconds to check all the three battery banks voltage so as the charger revision. Understanding the Function Key ‘INFO’, ‘NEXT’ and ‘SET’ during Charger Setting: ‘INFO’: Press and hold the key for longer than 3 seconds to enter charger setting mode and show function setting. Once new setting is done, press ‘INFO’ again to exit the charger setting mode.
Procedure to set or view charger setting: Follow the procedure or sequence in Appendix A1 and A2 to set or view the charger setting.
Procedure to Equalize Flooded Battery: DANGER: Explosion Hazard. The battery generates explosive gases during equalization. Follow all the battery safety precautions listed in the manual. DANGER: Explosion Hazard and Risk of Battery damage. When using the equalization mode, the user has to be sure the battery connected to the channel is a flooded battery type. Equalizing a non-flooded battery may overcharge the battery and may cause the battery to explode. CAUTION: Risk of Battery and Equipment damage.
will recover automatically back to maximum charging current when the environmental temperature drops to below 45°C. Over Temperature Shutdown: When the charger senses the environmental temperature is above 60°C, the charger will shutdown. It will recover automatically when the environmental temperature drops to below 45°C. Battery Reverse Polarity: When a reverse polarity is connected to the battery bank, Fault Code E03 on display will appear.
