8.14 Simulation
Here, the voltage, frequency or a vector surge can be simulated and the setting can be tested. All 3
phases plus the 10 minute mean value are always simulated. All functions of the device operate as if this
value is actually being measured. Alarm and error messages are only indicated with the LEDs and not in
the display.
The set values are simulated until the menu item
is exited with the or
button. If the UFR1001E is sealed/locked, simulation is not possible.
If the section switch feedback contacts are connected to the UFR1001E and enabled, (set value >
section-switch turn-on time under
8 8 ), after a shut-down, the tripping time (dAL + time of slowest
section switch) is displayed.
Adjustment process:
Select the menu item with the buttons until display 8 8
Press the button 1x display 8 8 8 8
Use the buttons to set the measurement factor for simulation:
o
8 8 V 10min mean value (frequency = last simulated value)
o
8 8 Frequency (voltage = last simulated value)
o
8 8 Vector shift
Press the button 1x display 8 8 (selected measurement factor is simulated)
Use the buttons to set the desired value
After exiting the Simulation menu item with the buttons, the unit switches over to monitoring the
limits.
The unit automatically returns to the display mode if no button is pressed for 15 minutes.
Hint: A limit value should be tested that is higher than the set 10min mean value. If the 10min mean
value has to be temporarily switched off, set ( 8 8 8 8 since otherwise it will trip first. The
same applies, for example, for , during a simulation of in Pr3 and Pr4. (Medium
