OPERATING INSTRUCTIONS

Charge Operation
To provide the ingress protection specified by design, the charger needs to be operated with both doors locked. All battery charging operations can be accomplished without directly accessing the control panel by physically connecting charger terminals to the battery terminals and using push buttons accessible in the front of the charger. Please refer to “Maintenance and Service” section for picture references.
Charger idle display: With the charger in wait mode (no battery connected) and without pressing the Stop/Start button, the display will show the following information:

• Connect battery: Make sure the charger connector(s) matches the battery connector(s). Plug the charger connector(s) to the battery connector(s). For chargers with dual connectors, both connectors must be connected in order to start a charge.

• NexSys ®iON Li-ion batteries come with specific type of connector. The NexSys+ Outdoor charger comes with 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 1first. All NexSys® iON 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 Stop/Start button if the battery is already connected. When charging a NexSys® iON battery, the CAN communication between the battery and charger is established and the message “BMS CONNECTED” will be displayed on the screen.
After 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. Figure1.

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.

OPERATING INSTRUCTIONS

Operating Instructions
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® battery monitoring device in range is connected to the battery charger. Once the charger makes the determination, it downloads data from Wi-iQ battery monitoring device, displays the battery S/N, updates the profile capacity  and temperature for charging, and starts the main charge.

Li-ion only: Max current and voltage requested by BMS
8| Battery S/N from Wi-iQ® battery monitoring device
