3 Design and Function
3 Design and Function
The electronic rotational speed monitoring device JMNC
is applied together with a pulse indicator for monitoring
and controlling drives. The pulses of the indicator are
analysed by the speed monitoring device which signals
the overspeeding or underspeeding of a nominal rota-
tional speed.
3.1 Design
The electronic rotational speed monitoring device JMNC
is equipped into a solid plastic housing (8), which can be
mounted onto an operating panel by means of screws.
All indicating and operating elements are assigned to
the front side of the device (s. fig. 3-1).
Potentiometer start-up delay (1), "run-up bridging"
This potentiometer serves to set the duration of the run-
up bridging in between 0 and approx. 45 seconds.

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.

3.2 Function Principle of the JMNC
3.2.1 General
In connection with a rotational speed indicator, the rota-
tional speed monitoring device JMNC is used to monitor
drives for underspeed, standstill, or overspeed.
The pulses of the rotational speed indicator are ana-
lysed by the monitoring device, which signals the under-
speeding or overspeeding of a set nominal rotational
speed.
The indicator input (17) (terminals 1/2) of the rotational
speed monitoring device is designed for rotational speed
indicators complying with the npn and Namur regula-
tions. The indicator input (17) can be monitored by
means of the light-emitting diode LED orange (4).
Any number of monitoring devices JMNC can be con-
nected to one pulse indicator.
The output relay (16) of the rotational speed monitoring
device is a change-over contact. The current switching
status of the relay is indicated by the light-emitting diode
LED green (5).
In addition, the rotational speed monitoring device JMNC is
provided with a pulse output to connect common digital ro-
tational speed counters (see section 5.3.1, Connection As-
signment).
3.2.2 Run-up Bridging
In order to start up the plant, the rotational speed moni-
toring device JMNC is provided with the feature run-up
bridging.
By means of the potentiometer start-up delay (1) the pe-
riod of the run-up bridging can be set in between 0 and
45 seconds. During this time, the output relay (16) re-
mains attracted, and the plant can be started.
Type Number/switch-over contact
JMNC 1 x change-over contact (open contact/closed
contact)

3 Design and Function
3.2.3 Underspeed Monitoring/Switching Function
(with run-up bridging)
During the set run-up bridging period the output relay (16)
is attracted (see also fig. 5-4).
After expiration of the run-up bridging period, and when
the drive operates with a constant rotational speed, the
output relay (16) remains attracted and the green LED (5)
lights. The orange LED (4) flashes in the cycle of the in-
coming pulses.
Underspeeding of the nominal rotational speed
If the set rotational speed is not reached, the output relay
(16) drops and the green LED (5) extinguishes (see also
fig. 5-4).
