6.4 Local adjustment from the digital display
In nuclear power plants, all on site modifications of the configuration of the FCX-AII
transmitters may only be done with the aid of the mobile communicator.
1. Description
If the transmitter is equipped with a numerical indicator, the local adjustment on the FCX
transmitter-AII is possible without the use of the FXW mobile communicator.
The following switches are integrated on the digital indicator to perform the local settings:
