2 1.0 Option 16 Series Operation 1.1 General Description The 16 series option includes the LED user-interface display panel which has eleven functional LED indicators on the front panel. One LED is used to indicate Equalize mode, one LED is to indicate AC voltage, five LEDs are used for various alarms, and four LEDs are used for display indications. The display also has a High Voltage Shutdown alarm reset push button and an Equalize/Select toggle switch. Figure 1A LED Display Showing System Output Voltage (while in Float mode) Toggling down on the Equalize/Select switch changes the display. The four green meter-select LEDs that are mounted horizontally on the bottom of the display indicate the display status. The following items can be displayed and have an LED indicator: DC Volts Displays the output DC voltage. DC Amps Displays the output DC amperage. Timer Mode Shows what Equalize timer mode the charger is currently set for. Figure 1B Display Diagram NOTE: In 16J, 16Q, 46T, and 46U option, the two LEDs will also be provided on the door as positive ground and negative ground alarm indicators. Refer to Figure 2. In 16P and 16T option, an audible alarm with silence switch will be provided on the front panel. Figure 2 Negative and Positive Ground LEDs (On Front Panel 16J/Q/T/U Option) EQ Time In Float mode, displays the set Equalize time. In Equalize mode, counts down from the Equalize set time. When the charger is in Equalize mode, the yellow Equalize LED will be on and the voltage will change to the set Equalize value. Refer to Figure 3A. Toggling down on the Equalize/Select switch until the green EQ TIME LED is on will change the display to indicate the Equalize timer countdown. Refer to Figure 3B.

3 1.2 Selecting the Charging Mode The digital display used in the 16 Series has two modes for DC output voltage; Float mode and Equalize mode. Float charging mode is used for all normal battery charging needs. Equalize mode is used when it is necessary to Equalize (or balance) the level of charge across all cells present in the battery. One LED is used to indicate Equalize mode on the front panel. There is no Float LED indicator. If the charger is in Float mode, simply toggle up the Equalize/Select switch to change into Equalize mode. If the charger is in Equalize mode, it will automatically switch back to Float mode after the designated Equalize time cycle is complete; alternatively, the charger can be manually switched to Float mode by toggling the Equalize/Select switch. 2.0 Alarms The available alarms for the 16 Series are: Low Voltage1, Low Voltage2, End of Discharge, High Voltage, Low Current, High Voltage Shutdown, Positive Ground, Negative Ground, AC Power Failure, and Summary. The corresponding alarm LED will illuminate when an alarm is triggered, if applicable. Figures 4A 4E illustrate the alarm relays provided on the 198 relay board. Each set of alarm relays have two sets of form C contacts which function identical to each other. Not all alarm relays function the same; refer to Table 1 for the logic of each relay.

There is no AC Power Failure LED, only alarm contacts. The alarm will automatically reset when AC power is restored to the charger. When AC power is lost, the front panel display and indicators will remain powered by the connected batteries. LOW DCV1 ALARM will trigger and the red LOW DCV1 LED will turn on if the DC voltage falls below the specified voltage threshold of the alarm for longer than 5 seconds. The alarm will clear once the low DC voltage condition is no longer present. LOW DCV2 / END OF DISCHARGE ALARM will trigger and the red LOW DCV2 LED will turn on if the DC voltage falls below the specified voltage threshold of the alarm for longer than 5 seconds. The alarm will clear once the low DC voltage condition is no longer present. Some options will define this as an End of Discharge Alarm with a different threshold. HIGH DC VOLTAGE SHUTDOWN ALARM will trigger and the red HI V SHUT DOWN LED will turn on if the output DC voltage of the charger rises above the alarm threshold for longer than 20 seconds and there is load on the charger. If the high DC voltage shutdown alarm activates, the DC output of the charger shuts off to prevent irreversible damage to the battery. This alarm will stay latched until the charger is reset by isolating from all power sources or pushing the reset button. NOTE: This alarm will not trigger if there is a Low Current alarm present. HIGH DC VOLTAGE ALARM will trigger and the red HI V LED will turn on if the output DC voltage rises above the specified voltage threshold of the alarm for longer than 5 seconds. The alarm will clear once the high DC voltage condition is no longer present. LOW DC CURRENT ALARM will trigger and the red LO A LED will turn on if the output DC current of the charger falls below the alarm threshold for longer than 5 seconds. This alarm can be disabled if considered a nuisance alarm. SUMMARY ALARM will default trigger if any of the other alarms are triggered. There is no Summary alarm LED, only alarm contacts. The Low Current, AC Power Failure, and Ground Detection alarms can be removed from the Summary alarm, but are included by default. POSITIVE GROUND ALARM will trigger and the green POSITIVE GROUND LED will turn on if 1.2mA or greater current is measured between the positive terminal of the battery and earth ground for longer than 5 seconds. This LED is found on a separate circuit board. The alarm will clear once the positive ground fault is no longer present. NEGATIVE GROUND ALARM will trigger and the green NEGATIVE GROUND LED will turn on if 1.2mA or greater current is measured between the negative terminal of the battery and earth ground for longer than 5 seconds. This LED is found on a separate circuit board. The alarm will clear once the negative ground fault is no longer present. 4

If required, change the alarm threshold levels after verifying with battery manufacturer. 2.3 Alarm Connection Procedure Before making any alarm connections, ensure that the AC power is off at the main breaker. Verify that no voltage is present by using a voltmeter at all AC and DC terminals. For relays mentioned as ENERGIZED on alarm condition: If it is desired that the annunciator be active until the alarm triggers, connect the annunciator leads to the NC and C contacts of the desired alarm (located on the relay alarm contacts on S2A-198 board). If it is desired that the annunciator be deactivated until the alarm triggers, connect the annunciator leads to the NO and C contacts of the desired alarm. For relays mentioned as DE-ENERGIZED on alarm condition: If it is desired that the annunciator be active until the alarm triggers, connect the annunciator leads to the NO and C contacts of the desired alarm (located on the relay alarm contacts on S2A-198 board). If it is desired that the annunciator be deactivated until the alarm triggers, connect the annunciator leads to the NC and C contacts of the desired alarm. 5

6 3.0 Adjusting Parameters All equipment is shipped from the factory fully checked and adjusted based on the model number. Do not make any adjustments unless the equipment has been powered-up and the settings have been determined to be incorrect. If the settings have been determined to be incorrect, adjustments may be made as detailed below. 3.1 Customer Calibration Mode In Customer Calibration Mode, the customer can access and change various parameters. To access the Customer Calibration Mode, hold the Equalize/Select toggle switch up towards Equalize for about 5 seconds. After CAL appears on the LED display, immediately release the toggle switch. The parameters will automatically cycle every 5 seconds if no change is made. Once in calibration mode, the customer can raise and lower values with the same toggle switch. After the last setting is passed, the settings will automatically be saved. If a setting is accidentally passed over, the customer can press the reset push button and restart calibration from the beginning. The calibration settings are listed in order below with a brief description and default values. NOTE: Some chargers could have additional settings included in the Customer Calibration menu; contact La Marche for further explanation of settings not mentioned below. The Customer Calibration menu is as follows: Low Voltage 1 Alarm This setting changes the voltage threshold that causes the Low DC Voltage Alarm to activate. The default setting is 1.98 V/C (for Lead Acid batteries), based on the number of battery cells that the charger was designed for. The number and type of cells is listed on the charger s nameplate. (EX: A charger designed for 24L has a default Low Voltage alarm setting of 47.5VDC) Low Voltage 2 Alarm This setting changes the voltage threshold that causes the Battery End of Discharge Alarm to activate. The default setting is 1.75 V/C (for Lead Acid batteries), based on the number of battery cells that the charger was designed for. The number and type of cells is listed on the charger s nameplate. (EX: A charger designed for 24L has a default Battery End of Discharge alarm setting of 42VDC) EQ Timer Mode This setting changes the mode of the Equalize Timer. The Equalize timer mode determines when the charger will go into an Equalize charging cycle. The timer modes are Mode 0 (P0), Mode 1 (P1), Mode 2 (P2), Mode 3 (P3), and Mode 4 (P4). The default setting for the Equalize timer mode is Mode 0 (P0). The Equalize Timer Modes are discussed in further detail in Section 3.2. EQ Timer Setting This setting changes the amount of time that the charger remains in the Equalize charging cycle once activated. When an Equalize cycle is started, the charger will remain in Equalize mode until the time selected by this setting has passed. By default, the Equalize timer is set for 8 hours. The battery manufacturer documentation should be referenced for battery specific settings. High Voltage Shutdown Alarm This setting changes the voltage threshold that causes the High Voltage Shutdown Alarm to activate. The default setting is 2.50 V/C (for Lead Acid batteries), based on the number of battery cells that the charger was designed for. The number and type of cells is listed on the charger s nameplate. (EX: A charger designed for 24L has a default High Voltage Shutdown alarm setting of 60VDC) High Voltage Alarm This setting changes the voltage threshold that causes the High Voltage Alarm to activate. The default setting is 2.45 V/C (for Lead Acid batteries), based on the number of battery cells that the charger was designed for. The number and type of cells is listed on the charger s nameplate. (EX: A charger designed for 24L has a default High Voltage alarm setting of 58.8VDC) Low DC Current Alarm This setting changes the current threshold that causes the Low DC Current Alarm to activate. The default setting is dependant on the shunt size of the charger. This alarm can be disabled if considered a nuisance alarm by lowering the threshold value to OFF. 6

7 3.2 Equalize Timer Modes The 16 Series offers five different modes of Equalize charging operation. The Equalize mode can be viewed on the charger display by toggling the Equalize/Select switch until the green Timer Mode LED turns on. The Equalize mode can be changed via the Customer Calibration menu, refer to section 3.1. In all of the Equalize modes below, the charger will return to Float mode if the Equalize/Select toggle switch is toggled up or when it completes its full charge time. Mode 0 (Displayed As P0 ) Mode 0 is a manual Equalize cycle and is the default setting for the charger. When the charger is set for Mode 0, the Equalize cycle must be activated manually. Once activated, the Equalize timer will turn on and the Equalize "LED" will light. The length of the timer is eight hours by default and can be changed via Customer Calibration. After the timer cycles to zero, the charger will immediately return to Float mode. Equalize mode will not start again until it is manually activated by the user. Mode 1 (Displayed As P1 ) Mode 1 is an automatic Equalize cycle that activates every 7 days. The length of the Equalize cycle is determined by the timer setting. The length of the timer is eight hours by default and can be changed via Customer Calibration. When the Equalize timer expires, the charger will immediately return to Float mode. Equalize mode will restart again after 7 days. Mode 2 (Displayed As P2 ) Mode 2 is an automatic Equalize cycle that activates every 14 days. The length of the Equalize cycle is determined by the timer setting. The length of the timer is eight hours by default and can be changed via Customer Calibration. When the Equalize timer expires, the charger will immediately return to Float mode. Equalize mode will restart again after 14 days. Mode 3 (Displayed As P3 ) Mode 3 is an automatic Equalize cycle that activates every 30 days. The length of the Equalize cycle is determined by the timer setting. The length of the timer is eight hours by default and can be changed via Customer Calibration. When the Equalize timer expires, the charger will immediately return to Float mode. Equalize mode will restart again after 30 days. Mode 4 (Displayed As P4 ) Mode P4 is an automatic Equalize cycle that is triggered when the battery experiences a sizeable discharge. When the DC voltage drops below the Low Voltage alarm threshold, and exceeds the Low Voltage alarm time delay, Mode 4 is activated. However, the Equalize timer will only start and run the charger in Equalize mode for the duration set in the Equalize menu after the charger has raised the battery voltage high enough to clear the Low Voltage alarm. When the Equalize timer expires, the charger will immediately return to Float mode. 7

8 4.0 Display Calibration In order to calibrate the display voltage and current to match the measured values, two small potentiometers are provided, located on the bottom of the 225A display board. P1 potentiometer is used to calibrate the display voltage and P2 potentiometer is used to calibrate the display current. Please refer to figure 5. NOTE: Adjusting the potentiometers mentioned will NOT change the output of the charger; only the display values will be changed.
