    To ensure that the antenna is mounted in such a way that it optimizes the reception conditions, the signal indicator on OMNICON® 2G Modem must be monitored. Please see documentation for OMNICON® 2G Modem for further information. Kamstrup A/S · 5512-2065_A1_GB_BSI 13/33...

  • Page 14: Digital Inputs (Omnigrid Connect Built-In)

    Detection of an overloaded earth connection (in IT-nets) is realized using a spark gap (aka. disneu- ter). The spark gap is required to implement a mechanism for activating a potential free contact (i.e. “volt free” or "dry") that is connected to a digital input 1 on OMNIGRID Connect.

    (surge suppressor or surge diverter) for installations in the low-voltage distribution net. The pur- pose of this device is to reduce voltage spikes caused by, for example, lightning strikes. As surge protectors wear out over time, OMNIGRID Connect can monitor the status of the lifetime of the fuse.
