Configuring the EPW 400

6.2.32 Force-triggered
A measurement is started as soon as the force set with 'Start' is exceeded, and
stopped as soon as the force set with 'Stop' is not reached. With option 'Set distance
to zero at start' it is enforced that at the moment of exceeding the start threshold, the
actual distance is used as offset for measurement.
6.2.33 Start/stop from PLC
A measurement is started and terminated via the digital signal of an external control.
Using the option 'Trigger' means that when a particular force or distance value is ex-
ceeded, the other measured value is adjusted to zero.
6.2.34 Switching points
In the opened window you can define for each measurement program
separately:
– three switching points, either for a force signal or for a distance
– an analog output signal 0 - 10 V (if it is set)
The setting for the current program can be copied into other programs.
In the fields of column 'Value' you enter the value in kN (with signal 'force') or in mm
(with signal 'distance') for the switching points SP 1 to SP 3 with the help of the nu-
merical keypad. In column 'Signal' you change between force and distance measure-
ment by tapping on the input fields. With 'Active', the corresponding switching point is
activated or deactivated. A switching point can only be activated if it has been acti-
vated in the Configuration I/O menu.
The field 'abs.' indicates whether or not a triggered measurement is based on the
absolute zero point.
The 'analog out' field is only displayed if the analog outputs are configured in the
Configuration I/O menu.
Close the 'switching points' window by tapping on the 'Accept' button.
The configuration will be adopted.
