OPERATING INSTRUCTIONS
Operating Instructions
• Connect battery: Make sure the charger connector(s)
matches the battery connector(s). Plug the charger
connector(s) into the battery connector(s). For
chargers with dual connectors, both connectors must
be connected in order to start a charge.
• NexSys iON lithium batteries come with specific
®
type of connector. The NexSys
one or two connectors (LI Connector) depending on
the charger model. When the charger is equipped
with two connectors, both connectors must be
connected, otherwise charge cycle will not start.
Always connect connector 1 first. All NexSys
charger connectors are equipped with arcless option
called Late Make/Early Break to prevent arcing if
battery is disconnected while charging.
• When CAN communication is established between
the NexSys iON battery and charger, "BMS
®
CONNECTED" will appear on the display screen.
If the text "BMS CONNECTED" is NOT shown, the
charge cycle will not start. Check CAN wiring and
battery.

Start Charging
When a battery is connected to the charger, the control
board senses the voltage and after a short delay, the
charger starts charging the battery automatically if
auto start is set to ON. Push the ENTER/STOP and
START button if the battery is already connected.
When charging a NexSys
®
communication between the battery and charger is
established and the message "BMS CONNECTED" will
be displayed on the screen. After a few seconds, the
battery will close the charge contactor to initiate the
charge. The charger will start the countdown process
and will start displaying the charge information.
Delayed Start: If the charger was programmed for
delayed start, charging will begin following that
delay. When the battery is plugged in to the charger,
the display shows the time remaining before the
programmed charging starts. Figure 3.

Without a Wi-iQ battery monitoring device: If the
®
Wi-iQ battery monitoring device adapter is not enabled
®
or no Wi-iQ battery monitoring devices are in range,
®
effective charging starts after the programmed delay.
The charger uses profile, capacity and temperature
settings programmed in the Configuration menu.
Pairing with a Wi-iQ battery monitoring device: If one
®
or more Wi-iQ battery monitoring device adapters are
®
in range, the charger will turn on and apply current to
the battery. The display will show "SCAN" followed by
"IQLINK" . This routine determines which Wi-iQ
monitoring device in range is connected to the battery
charger. Once the charger makes the determination, it
downloads data from Wi-iQ
displays the battery S/N, updates the profile capacity
and temperature for charging, and starts the main
charge.
