1. Application and brief description
The UFR1001E system-disconnection relay monitors voltage and frequency in three-phase current
networks. In complies with the conditions for centralized NA-protection according to VDE-AR-N 4105 in in-
plant power generators >30kVA, for feeding into the low voltage grid and the BDEW Directive for feeding
into the medium voltage grid. When using with generators, the evaluation of feedback contacts for the period
of a shut-down and during the synchronization can be suppressed.
The device has two channels which makes it more fail-safe. Input circuitry, evaluation and output relay are
provided in duplicate. Two processors monitor each other mutually. Feedback contacts are used to monitor
the functioning of both output relays and the section switch. During an alarm both channels shut down, the
cause is displayed and it is reported through transistor outputs.
2. Summary of the functions
Applications include monitoring the network in generating plants such as solar and wind turbine generator
systems along with mains protection in combined heat and power plants, also with synchronous generators
(Vector surge).

Explanation
VSR display value
The highest measured value is always displayed. The display value is reset
to 0 by deleting the max. value and when resetting into the go (good) state.
Delay Enable On time
Runs down when starting the unit and after opening the enable input; during
this time there is no evaluation of the vector shift
Reset time
When a reset time 8dof 8is running, it is always counted down in the
display (shortest one first)
Reset
Use the Reset key or interrupt the control voltage for > 2 s (comply with reset
delay)
Display mode 8Scn8
After the last measurement it switches into the scan mode; this is indicated
by the display8scn 8.
All measurements will now be displayed cyclically for the time set in 8dit8.
MIN / MAX values
All min and max values are saved zero-voltage maintained (non-volatile).
Tripping time
(only with feedback
contacts connected)
Connecting the feedback contacts enables measuring the shut-down time.
After a tripping time with the test button it is displayed until a button is
pressed again with a resolution of up to 1ms.
Total shut-down time = Tripping time + Response time 8 dal.8

/ 36 www.ziehl.de
After a shut-down in the simulation mode the total shut-down time is
displayed until the button is pressed again)
The longer time of both channels is always displayed.
Alarm counter
The unit saves max 100 alarms (cause, measurement value, at operating
time). The LEDs indicate the cause; the tripping value that led to the alarm
each stands in the 7-segment display. Alternately the time difference, current
operating time –tripping operating time is displayed. (how long ago the
alarm triggered)
Cumulative alarm time
8tal .8
The cumulative alarm time TAL indicates how long the relay was switched
off due to an alarm. It is recorded with a resolution of 1 minute and only
when the control voltage is applied.
Query: In the display mode button to 8ac .8is displayed. 1x button =
Cumulative alarm time8tal .8
Standby mode
8vsr .88stby.8
If E1-E2 are closed (e.g., by ripple control receiver, timer, dimmer), Relays
K1 and K2 are switched off. The number and duration of the shut-downs is
recorded.
Query: In the display mode button to 8ac .8is displayed. 2x button =
Standby counter 8stby.81x button = Standby time 8stby.8
Standby mode
8vsr .88y1y2.8
If E1-E2 are closed, the evaluation of the feedback contacts is suppressed.
That means when using generators, a section switch can be used for mains
synchronization.
Automatic restart attempts
If there is an error by the feedback contacts 8err78, 2 restart attempts are
automatically performed in an interval of 10s.
False triggering by undervoltage trips (e.g. during a thunderstorm) do not
lead to permanent shut-down.

If no key is pressed for 30 s (simulation mode 15 min) one automatically returns to the display mode (the
most recently set value is applied during this)
Function button
Set / Reset
Press briefly: The settings are taken over; continue to next parameter.
Changes into menu mode after the last parameter
Press for ≥ 2 s: Returns to the display mode (the most recently set values are
then applied)
Function key
Up / Down
Press briefly/long: Value change of the parameter (slow/fast)
Hint: Simultaneously pressing the Up and Down keys resets the adjustable value to zero. If the Up or Down
button is kept pressed while setting the value the change in the display is accelerated.
8.7 Test mode (only activated and connected feedback contacts)
If feedback contacts of the section switch are connected to the UFR1001E and activated (value > set turn-
on time of section switch, e.g. 5.0s), the trip circuit can be tested by pressing the Test button. To do that, the
measurement voltage has to be connected and no alarm is allowed to be present!
After pressing the Test button the UFR1001E triggers. The tripping time of the internal relay + section switch
are measured through the feedback contacts. After successful tripping, the tripping time of the slower switch
remains shown in the display until any key is pressed.
8.8 Alarm counter
The alarm counter 8ac 8is increased by 1 with every shut-down. Up to 100 shut-downs are counted. That
allows quick detection of how often the UFR1001E has shut down since the last delete of the alarm counter
(see cumulative alarm time).
Query the alarm counter:
Change into the display mode
Press the button several times until display 8acxx8
8.9 Cumulative alarm time (display in hours)
The cumulative alarm time 8tal 8indicates how long the relay was switched off due to an alarm. It is
recorded with a resolution of 1 minute and only when the control voltage is applied.
Query the cumulative alarm time:
Change into the display mode
Press the button several times until display 8acxx8
Press the button 1x display 8tal 8/ 8x.xx8
Delete the alarm counter and cumulative alarm time (only together):
Display alarm counter8acxx8
Press the button 1x display 8tal 8/ 8x.xx8
Keep the button pressed for 2s until display 8tal 8/ 80.008

8.10 Alarm memory
Independent of the alarm counter, the UFR1001E stores the most recent 100 shut-down causes (cause,
measurement value, at operating time). Simulated alarms are also registered. The LEDs indicate the cause;
the tripping value that led to the alarm each stands in the 7-segment display. Alternative to that
the time is shown in hours which have passed since the last tripping (with applied control voltage).
These values remain saved even after the power has been turned off.
Query alarm memory:
Change into the display mode
Press the button several times display 8acxx8
Press the button 1x display 8 x.xx8/ 8x.xx8
(tripping value or error no. / time that has passed in hours)
Press the button 1x, go to next alarm
The alarm memory is only deleted during a program change.
8.11 Standby counter and standby time
The standby counter 8stby8, is increased by 1 with every standby shut-down. Up to 9999 shut-downs are
counted. That lets the UFR1001E quickly detect how often, e.g., shut-down was performed through a ripple
control receiver.
Query the standby counter:
Change into the display mode
Press the button several times until display 8acxx8
Press the button 2x display 8stby8/ 8xxxx8
The standby time 8stby8indicates how long the relay was switched off by the standby mode. It is recorded
with a resolution of 1 minute and only when the control voltage is applied and if no alarm is present.
Query the standby time:
Change into the display mode
Press the button several times until display 8acxx8
Press the button 3x display 8stby8/ 8x.xx8(Time LED is illuminated)
Delete the standby counter and standby time (only together):
Display alarm counter8acxx8
Press the button 2x display 8stby8/ 8xxxx8
Keep the button pressed for 2s until display 8stby8/ 808

8.12 Code lock
You can protect the set parameters by enabling the code lock here.
The device acknowledges an incorrect entry with 8err8(flashes three times).
Adjustment process:
Select the menu item with the buttons until display 8Code.8
Press the button 1x display 8Pin 8/ 808
Set the saved pin code with the buttons (default setting is 85048)
Press the button 1x display 8Code8/ 8off 8
Use the buttons to set the desired code lock:
o8off8off, all parameters can be changed
o8On8on, no parameters can be changed
Press the button 1x display 8Pin 8/ 85048
Use the buttons to set the new, desired pin code (caution: write down the pin code)
Press the button 1x
Code lock on, display 8on8flashes three times
Code lock off, display 8off 8flashes three times
Return to menu mode, menu item code lock
If there are any problems with the code lock (pin forgotten), the lock can be switched off and the pin can be
reset to 504 by keeping the Set key pressed while switching on the mains until 8Code8/ 8off8appears
in the display.
8.13 Sealing
All 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.

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 si . 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 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:
o8u 8Voltage + 10min mean value (frequency = last simulated value)
o8f 8Frequency (voltage = last simulated value)
o8vsr 8Vector shift
Press the button 1x display 82308(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 (8Um .88off.8since otherwise it will trip first. The same
applies, for example, for U, , during a simulation of U,, in Pr3 and Pr4. (Medium voltage)
