  • Page 9: Mode: Switching

    MiniLog2 Mode: Switching Starting-, Stopping and using Pre Set Cycles The temperature compensated clock of the MiniLog2 allows synchronised switching even when being rarely synchronised. Typical time difference without synchronising is 20ms per day for 10°C to 30°C. Start Switching...

  • Page 12: Gps Synchronisation

    Mode: Switching GPS Synchronisation If the GPS receiver is connected with the GPS input socket, MiniLog2 automatically tries to synchronise itself every 6 hours with the GPS signal. If a synchronisation at once is required, one can start a GPS synchronisation manually.

  • Page 13: External Synchronisation

    MiniLog2 Mode: Switch External Synchronisation For the synchronisation of the MiniLog2 with an external switcher, choose the external synchronisation. The external switcher functions as "Master", while the MiniLog2 reacts on the opening of the external contact as a "Slave". The relay contact of the external switcher has to be connected in advance between the channel 1 input and GND.

  • Page 14: Manual Synchronisation

    Mode: Switch Manual Synchronisation For manual synchronisation of the MiniLog2, choose the manual synchronisation mode. The MiniLog2 will react on pressing the "Start" key, and taking this moment as the start of the off-period of the chosen switching cycle. Selecting Manual...
