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 % and stands by

until one of the communications recovers.

At the startup, it outputs -15 % until the communication is

established and normal data is received.
