UFR1001E 12420-0701-14 Page 27 / 34 www.ziehl.de11.14 SealingAll the settings and the simulation mode can be locked.If the LED is illuminated, the UFR1001E is locked.If an attempt is made to change a setting in the locked state, for 3s the display shows 8LOc 8.Adjustment procedure Sealing/Lock ON (OFF):• If present, remove seal (only authorised person)• Apply control supply voltage at A1-A2• Slightly lift the key cover and turn 180°• Actuate the small blue button by pressing the button cover very firmly (LED starts flashing)until the green LED is illuminated.11.15 SimulationHere, the voltage, frequency or a vector surge can be simulated and the setting can be tested. All 3 phasesplus the 10 minute mean value are always simulated. All functions of the device operate as if this value isactually 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 si . is exited with the orbutton. 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 8trel.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 8si .8• Press the button 1x → display 8si 8 / 8u 8• Use the buttons to set the measurement factor for simulation:o 8u 8 Voltage + 10min mean value (frequency = last simulated value)o 8f 8 Frequency (voltage = last simulated value)o 8vsr 8 Vector shift• Press the button 1x → display 8 2308 (selected measurement factor is simulated)• Use the buttons to set the desired valueAfter 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 hasto be temporarily switched off, set (8Um .8 → 8 off.8 since otherwise it will trip first. The same applies,for example, for U, , during a simulation of U,, in Pr3 and Pr4.
