It is recommended to install the switch for the supply voltage near the device and to mark it as
a disconnector for the device.
Use of the Synchronizer FHG66, and particularly of its alarm output, is recommended for
minimum point level detection, as an undetected failure of the Modulator FHG65 may result in
faulty switching behavior

Synchronizers FHG66
If more than three radiation sources are used, the synchronization chain must be extended by
cascading: here, an additional synchronizer (3) is connected to one of the outputs of the
synchronizer (2) instead of a modulator. All connected Gamma Modulators then operate in common
