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

recovers.

At the startup, it outputs -15 % (or approx. -11.5 V) until the

communication is established and normal data is received.
