For the system to operate correctly, it is essential that all loads and chargers are able to be controlled by
either DVCC or the ATC and ATD signals. Ideally wire the ATC and ATD signals to a devices remote on/off
connector, or, if that is not available, a
or
can be used.
5.3.6. Wiring a Remote on/off switch
Instead of the pre-installed wire loop between pin 10 and pin 11, a simple on/off switch can be wired to remotely turn the Lynx
Smart BMS on and off.
See below example for correct wiring:
Remote on/off
Simple Remote on/off switch wired between pin 10 and pin 11
For the Lynx Smart BMS to operate, the contact between pin 10 and pin 11 must be closed.
5.3.7. Programmable relay wiring
The programmable relay is an SPDT relay (Single Pole, Double Throw) with 3 contacts:
• Common (COM)
• Normally Open (NO)
• Normally Closed (NC)
The relay makes contact between COM and NC when the relay is not active, while COM and NO makes contact when the relay is
activated.
Depending on the Relay mode setting (Alarm relay or Alternator ATC) in the VictronConnect app, an audible (buzzer or external
speaker) or visible device (LED signal) or the signal line (usually the ignition wire) for the ATC signal of an external alternator
regulator can be connected.
