EEPROM Configuration After Main PCB replacement NOTE: The configuration procedure can be activated only within 5 minutes after power on. The configuration must be completed until receiving test End display, otherwise the configuration will be lost. If the PCB has never been configured before, the display shows F11 Error code when unit turned on.
Configuration Every time power is on, the latch auto-test cycle is carried out. The lock icon flashes while the latch is moving. 1. 2. Display SOFTWARE VERSION 3. Keep pressing...s00 -> S01 -> until S11 4. Press and again, then Hold and to return to the normal working mode
