I'm receiving a Bridge Temperature Sensor Fault

See the article below to discover the potential causes for a Bridge Temperature Sensor fault as well as the recommended corrective actions to fix it.

Handling actuator cables and connections while the ACM is powered on could cause injury or death. This equipment operates under extremely high voltages. Always turn off the system power by unplugging ACM power cord before handling them.

You must ask D-BOX Support's authorization prior opening the main cover of an ACM. Opening the main cover of an ACM without formal authorization voids the warranty.


Potential causes Corrective actions

The error can be triggered by
starting the system when the
temperature is too low.

This error can also be triggered if the internal power bridge sensor is defective.

  1. Make sure your system is running in a temperature range of 0 to 40°C.
  2. Check if the fan is working.
  3. Make sure there is enough ventilation around the ACM.
  4. If the problem persists, replace/repair the faulty ACM.
