Master reset
The master reset restores the basic device setting (physical address 15.15.255, firmware re-
mains in place). The device must then be recommissioned with the ETS.
During secure operation: A master reset deactivates device security. The device can then be re-
commissioned with the device certificate.
Performing a master reset
Precondition: The safe-state mode is activated.
￭
Press and hold down the programming button for > 5 s.
The programming LED flashes quickly.
The device performs a master reset, restarts and is ready for operation again after ap-

Restoring the device to factory settings
Devices can be reset to factory settings with the Jung ETS Service App. This function uses the
firmware contained in the device that was active at the time of delivery (delivery state). Restor-
ing the factory settings causes the devices to lose their physical address and configuration.
