2. Functions and features
The FD-1/FD-1 N monitor is a pulse evaluation system for direction and speed
monitoring.
For direction monitoring the monitor receives pulses from external pulse pick-ups
via 2 separate input channels, evaluates the pulse shifts (pulse sequence In1 before
In2 or the other way round) and switches output 1 according to the set parameters.
The input pulses must be phase-shifted and must overlap for a time of approx.
0.25 ms.
direction monitoring
The parameters of the monitor can be set in a way that the preset direction is either
left-hand movement or right-hand movement. When the preset direction is detect-
ed, the output relay energises / the transistor output switches (status signal), when
the opposite direction is detected, the relay de-energises / the transistor output is
blocked (fault signal).
