When conditions warrant a manual stop, pressing the red Stop key brings the charging operation to a halt safely without damaging batteries. Alphanumeric display Archive charge cycle data The AC2000 features an eight-character alphanumeric LED dot matrix display that brightly illuminates messages and numbers that are distinguishable from over ten feet away. Through easy to understand messages, the alphanumeric display allows viewing of charge status; archive, programming or review information; fault condition and operating status. The AC2000 automatically archives up to 19 items of charge cycle information for the last 99 cycles of charge operation. Upon connection of a new battery, the most recent charge cycle is labeled #1 and all previous archive data is shifted to the next archive location (1 to 2, 2 to 3, etc.). Cycle data is accessible in two ways: 1) display up to nineteen items for the selected cycle or 2) view one data item for all available cycles. Scroll forward and backward through archived data, by pressing UP and DOWN arrow keys. Selectable display readout The default feature of the AC2000 continuously displays the output voltage and current during the charging operation. Change this display to ampere-hours returned or time on charge by simply pressing appropriate keys. Easy to program 30 functions allow you to program the AC2000 with ease. Before beginning the charging operation, press the PROGRAM/REVIEW key to scroll through the menu and select PROGRAM. Simply key in the function number and press ENTER or use the arrow keys to scroll to the desired programming function and key in the desired settings. Optional security system The AC2000 can be set to automatically display a message prompting for a four-digit password before proceeding with programming alterations. This optional security system protects control settings from unauthorized changes. Charge cycle review The AC2000 can retrieve and display up to 48 items of charge data. The Cycle Review key provides access to speciﬁc charge information at any point during the charge cycle without interrupting the cycle. With the touch of a button, the following charge information is displayed for review: 1. Ampere-hours returned to the battery 2. Total time on charge (in hours and minutes) 3. 80% to charge complete (in hours and minutes) 4. Battery open circuit voltage 5. Start current 6. Start voltage (per cell) 7. Finish current 8. Finish voltage (per cell) 9. Charge termination code Program the AC2000 to start the charge cycle at a predetermined time of day. Time-of-day start enhances charging schedules plus helps to reduce utility rates when programmed to begin the charging operation during offpeak hours. Delayed start Program the AC2000 to delay the start of charge for up to 24 hours. With the selection of delayed start and upon connection of a battery, the delay time appears on the digital display and counts down, in one minute intervals, until it reaches zero at which time charging will start. Use delayed start for battery cool-down before recharging to increase battery efﬁciency and extend battery life. Program different delay times to stagger-start charging of batteries to ease high-peak energy demands. Time-of-day blockout PT/DV/DT Charge Termination The AC2000 utilizes our patented charge 2.6 termination technique, DV/DT, or rate of change of battery voltage with respect to 2.5 0% time, with proportional time (PT) to determine when to terminate a charge 20% 2.4 40% cycle.

VOLTAGE (PER Time-of-day start The AC2000 can be programmed to blockout a predetermined amount of time during the course of the day. The charger will turn off at the beginning of blockout and resume charging at the end of the blockout period. Use timeof-day blockout to efﬁciently save on energy costs, prevent unnecessary charging that may inadvertently result due to operator lunch or break periods, or for battery cool-down. power. A lithium battery and a microcomputer chip combine to ensure proper program maintenance, eliminating the need to reprogram when power is resumed. Automatic start operation High-current shutdown Five seconds after the battery is connected, the AC2000 will automatically begin the charging operation, eliminating the need for timers or dials to be set. This delay provides time to check for proper battery connection before the charge cycle begins. Manual start is also available. The display will read “Enter to Start” and not start the charge operation until the ENTER key is pressed. By monitoring both the output current and voltage throughout the entire charge cycle, the AC2000 will recognize a battery in thermal runaway and shut down the charger, preventing damage to the battery. Charge status at a glance Bright LEDs illuminate when a charge is in progress, the battery is 80% charged, the charging operation is complete and the battery is on an equalize cycle. At a glance, know exactly which phase of the charging operation is taking place. Fault conditions are easily detected through the simultaneous ﬂashing of LEDs, plus the AC2000 will display a message to indicate the fault condition. Cool down option The AC2000 can be programmed to delay illumination of the “Charge Complete” LED until after a speciﬁed cool down time has elapsed. Adjustable from 0-8 hours, this efﬁcient feature helps to prevent battery overheating and extend battery life. Refresh charge An equalize charge of three hours beyond a normal DV/ DT charge termination can be selected manually or automatically. Automatic equalization can be programmed by day of week or by number of charge cycles from 0 to 30. When the automatic equalize function is selected, the manual push-button is disabled to prevent unnecessary equalize charges. Featuring an adjustable 8 to 99 hour refresh charge timer, the AC2000 can be used to provide a refresh charge to stored batteries to replace normal losses associated with storage. Similarly, in situations where it is anticipated that the battery and charger will be left connected for a period of time after charging – for instance, in the event of a long weekend or a week-long company shutdown – the AC2000 can be programmed to automatically provide a refresh charge to ensure a fully charged battery when you need it. New battery recognition after AC fail Extended run time After an AC fail during the battery charging process, charging will resume provided there has not been a battery change. If a change occurred, the AC2000 will recognize the presence of a “new” battery and begin a new charge operation. In severe battery applications such as cold storage, the AC2000 can be programmed to extend charge time for up to one additional hour past normal termination. Program and data retention The circuitry for communication with the BID module is included on the AC2000. This can add valuable battery speciﬁc information to the control archive records. Automatic or manual equalize operation The AC2000 will retain all programming and archive data for a minimum of ten years, even in the event of loss of AC BID interface One control for 6, 12, 18, 24, or 36 cell batteries with 100, 200, or 400 ampere full-scale digital ammeter Located on the AC2000’s printed circuit board are ten dip switches that allow you to customize the charging operation.
