Function

The device is equipped with a lamp monitor which
signals the current fl ow of the incandescent lamp back
to two electrically isolated, potential-free semiconductor
outputs A and B (outputs closed). If the lamp has not
been actuated, both outputs are open. In case of
a fault and/or a lamp failure at least one output is
opened.

Depending on the safety category, one or two out­puts are to be used for a reliable lamp evaluation.
In case of an incandescent filament short-circuit
in the lamp, the integrated fuse is tripped. It must
be replaced by a new fuse in accordance with the
specifi cations after the lamp has been replaced by a
lamp of equal wattage.
