When the Lynx Smart BMS is switched off the following happens:

• The ATC (allowed to charge) and ATD (allowed to discharge) signals are turned off, so that all loads and chargers are turned

off.

• When the battery current is low enough the contactor will open so that the DC system is disconnected from the batteries.

• The AUX terminal will de-power so that a connected GX device will also de-power.

• The Lynx Smart BMS goes into hibernation mode.

• Bluetooth will remain active.

There are 3 ways to operate the remote on/off feature:

• Wire a switch between the remote-H and the remote-L terminal. When the switch is open the Lynx Smart BMS is off and will be

on when the switch is closed.

• Present a High signal to the H terminal. If the H terminal is High (more than 2V) the Lynx Smart BMS switches on, and if the H

terminal is Low (less than 2V) the Lynx Smart BMS will switch off.

• Present a Low signal to the L terminal. If the L terminal is pulled to ground the Lynx Smart BMS switches on, and if the L

terminal is free floating the Lynx Smart BMS will switch off.

3.4. Pre-charge circuit

The Lynx Smart BMS is equipped with a pre-charge circuit. This will pre charge capacitive loads such as inverters or inverter/

chargers before the contactor closes.

During pre-charge checks are performed. If the connected load is less than 20 Ohm, the current is too large or pre-charging takes

too long, the contactor will not close and an error will be generated.

If a pre-charge error has occurred, the Lynx Smart BMS will, after a wait time of 30 seconds, again try to perform a pre-charge. It

wil try this up to a maximum of 20 times.

3.5. Fans

The Lynx Smart BMS has two built-in fans. These turn on shortly during startup, when the loads are pre-charged.

In normal operation the fans will also turn on when:

• The temperature exceeds 60°C (140°F).

• The current exceeds 320A.

• The dissipation in the contactor is too high (to prevent contactor overheating).

3.6. Battery Management System

Pre-alarm

The Lithium Smart battery sends a pre-alarm signal to the Lynx Smart BMS when one of its cell voltages drops below a set

threshold. The pre-alarm voltage threshold is set in the battery via the VictronConnect app. All batteries need to be set at the

same pre-alarm value.

When the Lynx Smart BMS receives a pre-alarm signal, it will activate its alarm relay and it will generate an alarm message. The

alarm message is generated at least 30 seconds before the loads are shut down via the ATD signal.

A requirement for pre-alarm to be active, is that batteries are used that support this feature. Older batteries did not have this

feature. To check if the battery is equipped with pre-alarm; connect to the battery with the VictronConnect app and see if the pre-

alarm feature is supported by the app. If the pre alarm setting is missing from the VictronConenct app, then the battery does not

support pre-alarm.

Allow-to-charge and Allow-to-discharge

The Allow-to-charge and Allow-to-discharge contacts control the chargers and loads in the system:

• When the battery is fully charged and the battery voltage gets too high or the temperature is to low, the allow-to-charge contact

is opened and charging has to stop.

• When battery voltage is low, the BMS adds a 30s delay before opening ATD if pre-alarm is not supported. An alarm message

will be sent immediately.

For this feature to operate correctly, it is essential that the loads and chargers are able to be controlled by the allow-to-charge and

allow-to-discharge signals. Ideally wire the signal to a devices remote on/off connector, or if that is not available a BatteryProtect

or Cyrix-Li relay can be used.

Contactor

If charging or discharging is not stopped and the battery voltage gets even higher or lower, the safety contactor will be opened to

disconnect the entire DC system to make sure the batteries are protected. This will only happen when the batteries are critically

low or when the batteries are overcharging.
