Information Flow within the Level Unit
The signals from a Transmitter enter the Level Unit into a
Transmitter Interface (LI) where they pass the zener barriers
and go on to the Signal Board (LCS). The components on the
Signal Board amplify and process the signals. The signals are
converted to digital form by the Signal Board and are sent to
the Processor Memory Board (LCM), where the signals are
digitally processed. The Interface Board (LCI) handles the
communication between the Level Unit and the Work Sta-
tion, the Backup Display, the I/O Box and a Service PC if one
is connected.
