Reset input

The optocoupler input RESET EXTERN (terminal 5 and 6) can be
switched via plus or minus. The input will respond to a pulsed
signal. It works in a range from +10 to +30 VDC and in a pulse
bandwidth of 0.5 to 5 s.
The application of a continuous signal will deactivate the
ADW 511A. A "Wrong Initial Setup" fault will be reported
after approximately 20 seconds due to safety reasons.
