System in Standby mode
Switch the system to ON mode using the soft switch in the VictronConnect app or a connected GX device.
Battery voltage issues
The Lynx Smart BMS, on first install, will auto detect the battery voltage and set to either 12V, 24V or 48V. Each set voltage has
a specific battery voltage range (threshold). If the Lynx Smart BMS measures a voltage that is outside this threshold, one of these
alarms will be generated:
• Probably wrong system voltage - red LED flashing 7 times every 4 seconds.
• Battery voltage not allowed - red LED flashing 14 times every 4 seconds.
To fix, check the battery settings or check the battery voltage.
This table indicates the voltage thresholds for each system voltage:
System voltage Voltage threshold
12V 9V - 15V
24V 16V - 30V
48V 32V - 60V
Pre-charge errors
There are two specific errors that can be generated during the pre-charge process:
• Pre-charge high current – red LED flashing 6 times every 4 seconds. The pre-charged energy or current has been exceeded.
• Pre-charge timeout – red LED flashing 5 times every 4 seconds. It has taken too long for the pre-charge process to complete.
Pre-charge faults are mostly caused by:
• A short circuit on the load output – potentially caused by a malfunctioning load or if there is a wiring issue like a short circuit.
• Loads with a too high capacitance or too low resistance (less than 20 Ohm) have been connected to the load output.
To fix these errors, turn off or remove some loads or chargers and rule out wiring problems or shorts.
Internal error
Contact your Victron supplier if one of the following errors are occurring:
• Internal supply error - Red LED flashing 12 times every 4 seconds
• Initialization error - Red LED flashing 9 times every 4 seconds
• Contactor failure - Red LED flashing 10 times every 4 seconds
• Hardware error - GX device alarm calibration lost - GX device alarm
8.3. Lynx Smart BMS operational issues
High discharge current
A high current alarm is given when the current is more than 600A for more than 5 minutes. The red LED flashing 8 times every
4 seconds. Reduce the loads connected to the Lynx Smart BMS so that the current through the Lynx Smart BMS will be below
500A.
High charge current
A high current alarm is issued when the current exceeds 600A for more than 5 minutes. The red LED flashing 8 times every 4
seconds. Turn chargers off so that the current through the Lynx Smart BMS will be below 500A.
Contactor (relay) issues
The Lynx Smart BMS is equipped with 3 guards to protect the contactor.
• Over current protection: an alarm is generated when the current exceeds 600A for 5 minutes.
• Contactor voltage monitoring: an alarm is generated when the voltage over the contactor is higher than 0.5V. A high voltage
indicates high resistance and high power dissipation, indicating a bad contactor.
• Electrical/mechanical protection: there are 2 thermal switches mounted on the busbar. The contactor opens and an alarm is
generated when the temperature of the busbars becomes higher than 130°C.
