2.2.4
Transistor Output Modules (Source Type)
햲
The fuse is provided to prevent the external wiring from burning when the output of the out-
put module is shorted. Therefore, the output module may not be protected. The fuse may
not operate if the output module is damaged due to other failure than short circuit.
햳
A blown fuse is not detected when the external supply power is off.

Thermal protection and short circuit
protection
After cooling down resp. elimination
of the short circuit the operation will
continue automatically.
Indication of activated protective
function
When a fuse blows, the ERR. LED is
switched on and a signal is output to
the head station.
햳
When a protective function is acti-
vated, the ERR. LED is switched on
and a signal is output to the
head station.
