Description
The NMG2 perform safety-related measurements of power driven machinery like presses, shears, welders,
riveters and robots. In accordance with national and international safety standards machines with dangerous
movements have to be equipped with protection devices. The improper placement of a protection device
(2-hand control, safety light curtain and so on) will result in the potential for injury of the operator. With the
NMG2 all the important measurement values such as stop-time, stop-distance and velocity are provided to
calculate the minimum safety distance. The safety distance is defined in national and international standards
EN ISO 13855 (EN999). To ensure maximum safety the stop-time measurements have to be repeated
periodically (6 months).
The measuring cable of the posiwire®Position Sensor will be connected to the moving part of the machine
with the magnetic clamp or a fixing screw. The Sensor sends an incremental pulse signal to the
microprocessor controlled counter. The stop position can be selected by a digital encoder. The operator will
adjust the stop position of the measurement to the position of max. velocity of the moving part of the
machine.
To determine this max. velocity NMG2 provides the following measurement functions:
•Measurement of the max. velocity within the complete movement
•Measurement of the velocity at the stop position
•Measurement of the position of the max. velocity
If the position signal passes through the determined stop position in the selected direction a galvanic isolated
contact will cause the stop of the machine and the stop-time measurement will be started. The position
measurement values will be recorded until the machine has stopped completely. The two displays of the
measuring device will show the measurement values of stop-time and distance. By pressing a button the
velocity at the stop position can be displayed. A measurement protocol will be printed. The NMG2 electronics
ensures that the measurement is started only at the adjusted stop position and only in the selected direction
of motion.
The NMG2 can be used as a comfortable position and velocity measurement system in different
applications. The measurement values can be transmitted to a PC or a Laptop via the RS-232 interface and
processed with any software. Additional an actuator can be controlled to interrupt a safety light curtain, so
that it is not necessary to insert the relay contact into the machine circuit.

Identification of Controls and Displays
[1] TEST RUN/ADJUST
This button offers a reset function in the ADJUST position. The values of stop time and stop distance will be
set to zero and the stop contact is in normal position. The machine can be operated and no measurement
will be performed. Measurement will be started in the TEST RUN position only.
[2] RELEASE/OPERATE
This button sets the function of the potential-free stop contact looped into the stop circuit of the machine
(OPERATE or RELEASE). In most cases the RELEASE function is used. This button must be set before
starting measurement!
[3] UP/DOWN
Toggles the measuring direction.
UP = pull out measuring cable = positive counting.
[4] PRINT ON/PRINT OFF
Switches the built in printer on or off.
[5] ZERO
Sets the measuring system to zero.
[6] Velocity measurement (Vmax)
In the VELOCITY MEASUREMENT mode the max. velocity and the corresponding position can be
measured.
[7] The Actuator Option
An actuator to break safety light curtains is available as an option.
[8] Automatic Measurement Mode
In the automatic measuring mode, it is possible to perform any number of measurements without pressing
the key ADJUST/TEST RUN. After each measurement, the stop contact is set to the normal condition
automatically and the machine can be moved. If the machine passes the stop point in the opposite direction
the measurement data will be deleted and the NMG2 is ready for the next test run.

4.3 Stop-Time Measurement
1. Configuration of the machine
Press the [1] button, “ADJUST” active
2. Set the Stop Contact or the Acutator (Aktor) (see page 25)
Button [2] released: “RELEASE” active; the safety circuit of the machine is closed and will be interrupted
at the Start Position (see 8.).
Button [2] pressed: “OPERATE” active; the safety circuit of the machine is open and will be closed at the
Start Position (see 8.).
3. Select the measuring direction
Button [3] pressed: downward measurement, “DOWN” active, pulling in the measuring cable corresponds
with the DOWN direction and will cause negative counting.
Button [3] released: upward measurement, “UP” active, pulling out the measuring cable corresponds with
the UP direction and will cause positive counting.
4. Set the printer
Button [4] pressed: “PRINT ON”, printer activated
Button [4] released: printer deactivated
5. Set the machine to ZERO
Arrange the machine in the upper or lower dead center and set to zero using the button [5] “ZERO.
6. Activate “Stop-Time measurement” mode
Button [6] released: “STOP TIME” active
7. Set Single/multiple measurement
Button [7] pressed: “Automatic measurement” mode, “MULTIPLE” active
Button [7] released: “SINGLESHOT.”mode active
8. Select the Start Position of the measurement
Adjust the “START POSITION” (lower display) with the jog wheel [9], this is usually the half of the whole
movement.
Button [3] pressed: negative value
Button [3] released: positive value
9. Prepare the machine for the measurement
Button [1] released, Mode “TEST RUN” is active, 4 bars appear on the display.
10. Let the machine perform the complete cycle (e.g. with the 2-hand control).
11. As soon as the moving part of the machine passes the determined stop position the stop contact will
cause the stop of the machine. After the NMG2 has detected the complete standstill of the machine, it
will display the parameters Stop Time and Stop Distance in the upper resp. lower display. The printout
starts, if selected.
In the automatic measuring mode, any number of consecutive measurements can be carried out. The safety
distance measurement will be determined only in this measuring mode.

4.4 Velocity Measurement
Steps 1 to 5: proceed as in the case of Stop-Time measuring
6. Activate velocity measurement
Button [6] pressed: “VELOCITY” active
7. Set the parameters for the velocity measurement
Button [8] is always released during the velocity measurement, “SINGLESHOT.” active
Adjust the “START POSITION” (start of measurement) with the jog wheel [9]. The recommended value
is +2 mm for upward movement and -2 mm for downward movement.
8. Activate the measuring mode
Now release the button [1], “TEST RUN” is activated, 2 bars appear on the display, NMG2 is ready for
the measurement.
9. Let the machine perform a complete cycle
10. Read the measurement value
After the machine has stopped, press and release the button ZERO [5] to obtain the measurement
values. The max. velocity will be shown on the lower display “MAX. VELOCITY” [18] and the
corresponding position will appear on the upper display “POSITION” [17].
The printout shows the maximum speed between the start position and the complete standstill of the
machine. The actual speed in the start position also appears on the printout, so that the speed at each point
of the stroke can be determined by adjusting the start position.

page 17).
1. Adjusted measurement start position. At this point the contact will be released and the measurement will
be started.
2. A velocity value lower than indicated will be detected as standstill. This velocity can be programmed by
the manufacturer between 1 ... 10 mm/s. Thus, very slow machines can also be measured. Standard
adjustment ex-factory is 10 mm/s.
3. Adjusted measuring direction
4. Adjustment of relay contact
5. The measured stop time
6. The measured stop distance with a resolution of 0.1 mm
7. Velocity at start point
If the NMG measuring system detects a return movement or an oscillation when the machine is stopped, the
following values will be additionally calculated and printed in single measurement mode :
8. Time to final standstill
9. Position of the final standstill
10. Maximum position achieved in return direction
