Ion 2100DC Backup System Troubleshooting

Troubleshooting

Error Description	Possible Causes	Fix
The battery failed pre-qualification test	The battery is highly sulfated. The charger is connected to a six-volt battery.	Replace the battery with a 12-volt deep-cycle marine battery.
Battery over-voltage	The charger is connected to a 24 volt battery.	Replace the battery with a 12-volt deep-cycle marine battery
Charge time monitor	Battery took too long to complete its charge: A. Load applied (e.g. the pump motor started) during charging. B. The battery ampere-hour rating is too large (max. 130 ampere-hours).	A: Be sure the pump cannot start during charging; reset the charger. B: Replace with correct size battery.
Excessive battery drain	Pump motor ran during charging (that is, with the main A.C. power ON), causing the system to shut down.	Check primary sump pump. The BBU generally runs only when the main A.C. power is out. If there has not been any power outage and the BBU has run, the primary pump itself may have failed.
Reverse battery connection	Charger is connected backwards to the battery. (That is, charger (+) to battery (-) and vice versa).	Reconnect charger (+) to battery (-)/(-) to (-).
Battery overheated	Cells in an old battery may deteriorate with age.	Replace the battery with a 12-volt deep-cycle marine battery.
Charging error	An internal error occurred in the charger during one of the charging states.	Unplug the charger for 10 seconds and then plug it in again. If error occurs again, refer to table below.

Error Light Indications

Note: This chart identifies light codes indicating various charger error modes. It only applies when the ‘Charger Mode’ light flashes yellow/green alternately. The light codes listed here do not relate.

“Silence Alarm/Reset” Rocker Switch: Push the left side of the rocker switch on the front of the charger to silence the alarm.

Note: This will not silence the alarm when the battery is below 8.2 volts or the system is in error mode.

The front of the charger has the LED status lights: A.C. Power, Pump Run Status, Alarm Silence, Battery Status and Charger Mode. The status lights only apply when the ‘Charger Mode’ light is not flashing yellow/green. The ‘Pump System Status’ LED stays lit after the back-up pump has cycled. To reset an error light, push the right side of the rocker switch, located under the LED legend, to the right. When you reset the system, the charger will start its diagnostic procedure (pre-qualification test, etc.) from the beginning. If the cause of the error mode is not corrected, the system will go into the error mode again.

Flashing	Off	Off	Flashing Yellow/Green	Battery Overheated
Flashing	Off	Flashing	Flashing Yellow/Green	Charge Time Monitor
Flashing	Flashing	Off	Flashing Yellow/Green	Excessive Battery Drain
Flashing	Flashing	Flashing	Flashing Yellow/Green	Failed Pre-Qualification Test
Off	Off	Flashing	Flashing Yellow/Green	Battery Over-Voltage
Off	Flashing	Off	Flashing Yellow/Green	Reverse Battery Connection
Off	Flashing	Flashing	Flashing Yellow/Green	Output Over-Current

Alarm Summary

Charger Light	On/Off/Flashing	Alarm Buzzer	Indicates
All LEDs	Flash ONCE	Off	Connected system to AC power or to battery; or, pressed ‘Reset’ when in ERROR mode
AC Power Status	On Very Slow Flash	Off Off	System is receiving AC power System is not receiving AC power
Pump Run Status	Fast Flash (2x/second) Slow Flash (1x/2 seconds) Off	Beep in synch with LED Flash Off Off	Pump is running. Press LEFT side of rocker switch to silence alarm Pump has run, but is not running now Pump has not run
Alarm Silence	On Off		Alarm is silenced Alarm is active
Battery Status	On Slow Flash Fast Flash Off	Off On On Off	System is not connected to a battery or is connected to a battery charged to less than 1 volt DC Battery voltage less than 10.9 volts. Alarm can be silenced Battery voltage is less than 8.2 volts. Alarm CANNOT be silenced System is properly connected to a battery
Charger Mode	Slow YELLOW Flash Solid YELLOW Flash Fast YELLOW Flash Solid GREEN Flashing alternately YELLOW/ GREEN	Off Off Off Off On - Beeping	System is in “pre-qualification” stage. This will last from 1 minute to 5 hours, depending on the condition of your battery. System is in the “Constant Current Charge” stage. This will continue until the battery voltage reaches approximately 14.3 volts. System is in the “Constant Voltage Charge” stage. This could last up to 14.5 hours until battery is fully charged. System is in ERROR mode. Alarm will beep in synch with one or more of the ‘AC Power Status’, ‘Pump Run Status’, or ‘Alarm Silence’ LEDs.

Audio Alarm Indications

Charger Light	On/Off/Flashing	Alarm Buzzer	Indicates
On - Beeping	Slow beep in synch with ‘Battery Status’ LED	Battery is down to about 10.9 volts	Investigate cause; battery is very low. You have limited pump run time left. Press and release LEFT side of toggle switch to silence alarm.
On - Beeping	Fast beep in sync from ‘Battery Status’ LED	Battery is down to about 8.2 volts	Investigate cause; battery is nearly dead. You have almost no pump run time left. Alarm CANNOT be silenced
On - Beeping	Fast beep in synch with one or more of the ‘AC Power Status’, ‘Pump Run Status’, or ‘Alarm Silence’ LEDs and with the ‘Charger Mode’ LED flashing alternately YELLOW/GREEN	System is in ERROR mode	Refer to ERROR Light Indicatons above.
On - Beeping	Fast beep in synch with ‘Pump Run Status’ LED	Pump is running	None. Alarm will stop when pump stops running. To silence alarm, press and release LEFT side of toggle switch
