    ·         By pressing and holding the Start/Stop button for 3 seconds, the device will activate communication

     

    Configuration

    In the CONFIG mode, the device connects immediately to elproCLOUD to retrieve the configuration. The display shows CONFIG.

    ·         When entering this state, the device communicates in a higher frequency for the first 30 minutes

    ·         After the receipt of the configuration, the device enters START mode immediately

    ·         By pressing the Info button the Start before Date / Expiry Date is visible

     

    Start

    When the display shows START, the device is configured properly and can be started according to the chosen start option.

    ·         By pressing the Info button the Profile information / configured info field / Start before Date / Expiry Date is visible

    ·         By pressing the Start/Stop button, the device starts logging (TRANSIT or DELAY). The RUN icon on the display indicates a successful start.

    The Start/Stop button is inactive for 2 minutes after start

    To reconfigure a device, delete the sensor in the cloud and reset the device

     

    Delay

    Depending on the activation mode, the device will enter into DELAY or TRANSIT.

    ·         The display indicates the DELAY mode by showing DELAY.

    if DELAY mode “press button to activate alarm limits” is configured, the display shows DELAY

    if DELAY mode “time delay” is configured, the display shows the remaining time

    ·         By pressing the Info button the actual measurement value / configured info field are visible

     

    Transit

    In TRANSIT, the alarm limits are activated (if configured). The Alarm on/off icon appears (Alarm on).
