Command Overrun Fault

Read the article below to discover the potential causes for a command overrun fault as well as the prescribed corrective actions.

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 to manipulating it.

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.
