Simulation
Calculated damping
MINITRAC 31 • Foundation Fieldbus
If you have carried out a single point adjustment, this is the entered
value. With a two-point adjustment, this is the calculated value.
The value is an indication for the reliability and non-repeadability of
the switching point.
The greater the difference in the pulse rate between covered and
uncovered status, the greater the differential value (Delta I) and the
more reliable the measurement. The automatically calculated damp-
ing is also oriented around the Delta I value. The higher the value, the
lower the damping.
A Delta I value below 10 % is an indication for a critical measurement.
In this menu item you can simulate measured values via the signal
output. This allows the signal path to be tested, e.g. through down-
stream indicating instruments or the input card of the control system.
Note:
To carry out a simulation with the display and adjustment module,
you have to switch on the simulation switch on the electronics module
(switch position 1).
You can find the rotary switch on the electronics module in the elec-
tronics and connection department (large cover).
You can simulate different values:
Pulse rate of the sensor
Switching function of the relay
Information:
10 minutes after the key was pressed for the last time, the simulation
is interrupted automatically. You can also interrupt the simulation with
the switch on the electronics module.
The sensor calculates a suitable integration time automatically.
