FUNCTIONS
■
OUTPUT HOLD or OUTPUT OFF
In normal conditions, the module outputs the signal from
the preferred bus A.
When an error is detected, the output is switched to the
data from the bus B.
• Output Hold
If both are in error, the module holds the signal and stands
by until one of the communications recovers.
• Output OFF
If both are in error, the module outputs -15 % (or approx.
-11.5 V) and stands by until one of the communications re-
covers.
At the startup, it outputs -15 % (or approx. -11.5 V) until the
communication is established and normal data is received.
