Operation ENG 55
®
Active extension operation (Busch Watchdog ) with
6805U and FM Sensors:
Since the Master and Extension always have a separate
setting for the dusk value, the actual brightness conditions
at the installation site must be taken into consideration
individually.
The effective overtravel time is calculated by adding the
times at the Master and Extension. When used in
conjunction with FM Sensors 6800-xxx-104(M) or higher, it
is recommendable to operate the Extensions with the
shorttime impulse time setting if the times set at the
Master are to be adhered to as precisely as possible.
Refer to the appurtenant Operating Instructions of the
respective FM Sensor for further information.
