JMNC Operating Instructions
3 Design and Function
Set the required range of pulses by means of this
switch.
Fine (3), fine setting of the nominal value
The setting of the nominal value can be readjusted by
± 10%. Thereby, the switching point of the output relay
can be changed about 10% of the set rotational speed.
LED orange (4), input supervision
This light-emitting diode flashes with the cycle of the in-
dicator pulses. When the pulses increase 1500/minute,
the diode lights continually.
LED green (5), switching status of the relay
By means of this light-emitting diode the switching status
of the rotational speed monitoring device can be
checked.
Coarse (6), nominal value setting
By means of this potentiometer the rotational speed
monitoring devices can be aligned to the operating
speed of the drive.
Set button (7)
By pressing the red button the output relay (
16
) can be
controlled directly and will not drop during the setting.
