CS31 system bus error (no remote
units connected to the bus)
Note: If there are only analog units
connected to the CS31 system bus,
then this error could occur when
powering up while the analog units
are not initialized.
Reason: Analog units have a fairly
long initialization period. They are
therefore not recognized by the
basic unit during this initialization
phase.
