Filax 2

6. Troubleshooting and Support

In this section:

Consult this chapter in case of unexpected behaviour or if you suspect a product fault.

The correct troubleshooting and support process is to first consult the common issues as described in this chapter.

Should this fail to resolve the issue, contact the point of purchase for technical support. If the point of purchase is unknown, refer to the Victron Energy Support webpage.

6.1. Incorrect voltage or frequency switching thresholds

Check if the frequency jumper has been set correctly.

If the jumper has not been set for the correct frequency, the voltage and frequency switching threshold levels will be incorrect. See the Technical specifications chapter for the voltage and frequency thresholds for each frequency setting.

6.2. Filax will not switch to the priority source

If the red priority fault LED is lit, this means that the Filax is not connected to the priority AC source.

  • Check if the priority supply is available and is within voltage and frequency thresholds.

  • Check the priority source wiring, circuit breakers, RCDs and fuses.

Not that if the red priority fault LED is not lit, the priority source is available and the filax should connect to it after 30 seconds.

6.3. RCD trips when Filax is transferring load

The Filax is a double pole make before break transfer switch. For correct RCD operation, both inputs should be seen as individual power sources. As such, both the input sources need to have a neutral-earth link. The neutrals are not allowed to interconnect between the inputs or between an input and the output.
