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).
The device complies with the requirements of the public utility power providers for conventional
protection in low and medium voltage systems >30 kVA.

4.2 Functional characteristics
Functional characteristics 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 8
8 is 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 8 8
After the last measurement it switches into the scan mode; this is indicated by
the display8 8.
All measurements will now be displayed cyclically for the time set in 8 8.
MIN / MAX values All min and max values are saved zero-voltage maintained (non-volatile).

UFR1001E 12420-0701-08 Page 7 / 45 www.ziehl.de
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 8
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
8 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 8 8 is displayed. 1x button =
Cumulative alarm time8 8
Standby mode
8 8 8 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 8 8 is displayed. 2x button =
Standby counter 8 8 1x button = Standby time 8 8
Standby mode
8 8 8 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 8 8, 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.
5. Important information
A marked switch and a protective device must be provided in the supply line in the
vicinity of the device (easily accessible) as a disconnecting element
(rated current ≤ 6A).
Flawless and safe operation of such a device requires proper transport and storage, professional
instillation and later commissioning along with operation as intended.
Only persons who are familiar with the installation, commissioning and operation of the device and who
are correspondingly qualified for their job are permitted to work on the device. They must comply with
the contents of the operating manual, the instructions attached to the device and the pertinent safety
regulations for the erection and operation of electrical equipment.
The devices are built and certified in accordance with EN 60255 and leave the factory in a safe and
technically flawless condition. To maintain this condition they must comply with the safety regulations
marked in the operating manual with the headline "Caution". Failure to follow the safety regulations can
lead to death, bodily injury or property damage to the device itself and to other devices and equipment.
If the information contained in the operating instructions/operating manual are not sufficient, please
contact us directly or contact your responsible agency or representative.
Instead of the industrial norms and stipulations stated in the operating manual and applicable in
Europe you must comply with the valid and applicable regulations in the country of utilisation if the
device is used outside of the area of application.

WARNING
Hazards electrical voltage!
Can lead to an electric shock and burns.
Disconnect and de-energize before working on the system and the device.
6. Assembly
The device can be mounted:
Distribution panel or control panel on 35 mm rail according to EN 60715
Comply with the maximum permissible temperature when installing in a switch cabinet. Ensure
sufficient clearance to other devices or heat sources. If cooling is inhibited, e.g., through close
proximity to devices with increased surface temperature or interference with the cooling-air
current, the permissible ambient temperature is decreased.
Caution!
Before you apply mains voltage to the device, make sure that the permissible control
voltage Us on the side rating plate matches the mains voltage connected to the device!
