Lynx Smart BMS The Remote on/off switch must be turned on or a wire loop must be inserted between pin 10 and pin 11 of the multi connector. Check that the multi connector is correctly seated. Soft Switch turned off in VictronConnect App Switch the system to ON mode using the soft switch in the VictronConnect app. 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: 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 9.3. Lynx Smart BMS operational issues High discharge current A high current alarm is given when the current is more than 600A (1200A) for more than 5 minutes. The red LED flashes 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 (1000A).
High charge current A high current alarm is issued when the current exceeds 600A (1200A) for more than 5 minutes. The red LED flashes 8 times every 4 seconds. Turn chargers off so that the current through the Lynx Smart BMS will be below 500A (1000A). 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 (1200A) for 5 minutes.
