3 Application and brief description
The voltage and frequency relay UFR 1001 monitors the voltage and the frequency in one- or three-phase
voltage grids with or without N and, if required, switches rapidly off. The unit can be easily adapted to the
network operator's requirements.
With the integrated vector-surge relay, it is also suited for monitoring synchronous generators.
After selecting a basic program, the limits for over/undervoltage and the over/under frequency can be
programmed.
When using programs with vector-surge monitoring, the K2 relay only reports the vector surge.
4 Summary of the functions
Applications include monitoring the network in large photovoltaic plants, power system protection in
combined heat and power plants, also with synchronous generators
(vector surge) or in general, monitoring the network quality in systems, on machines or
in power supply systems.
The device complies with the requirements of the power suppliers for conventional
protection in low-voltage systems >30 kVA.
•4-digit digital display for voltages, frequency and vector surge
•Under and overvoltage monitoring 40…520 V
•Under and overfrequency monitoring 45.00…65.00 Hz
•Monitoring the voltage quality (10 minute mean average value)
•Vector-surge monitoring 2.0…20.0 °
•Response time adjustable 50 ms…60 s
•Reset delay (zero voltage maintenance) can be set 0…1000 s (Vector surge 3…240 s)
•Alarm-counter for up to 100 alarms (with measured value and reason)
•Added time of alarm up to 999 hours. Displays the time, alarms have been active (while supply voltage
applied only).
•LEDs for alarm signals, measurement value allocation and relay status
•2 output relays, each for frequency and/or voltage monitoring
•Relay function operating or idle current programmable
•Locked shutdown or auto-reset programmable
•External input for Enable / Reset
•Delay time for Enable input during vector-surge monitoring
•Easy to program with 5 selectable basic programs
•Code protection against manipulation of the setpoint values
•Sealing facility for set point values
•Control voltage AC/DC 24-270 V
•Distributor housing for panel mounting 4 TE, front-to-back size 69 mm
•Mounting on 35 mm mounting rails DIN EN 60715

6 Important notice
WARNING
Hazardous electrical voltage!
Can lead to electric shock and burns.
Before starting work, switch plant and device voltage-free.
The flawless and safe operation of a device requires that it is shipped and stored appropriately,
professionally installed and put into operation and operated according to its intended use.
Only people who are familiar with the installation, commissioning and operation and who have qualifications
corresponding to their job are permitted to work on the device. They must comply with the contents of the
operating instructions, the notices attached tothedevice and the relevant safety regulations for constructing
and operating electrical plants.
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 state you must comply with the safety regulations indicated
with "Caution" in the operating instructions. Non-compliance with the safety regulations can lead to death,
bodily injury or property damage on the device itself and on other devices and equipment.
If the information in the operating instructions is insufficient at any time, please contact us directly or
contact the representation responsible for you.
Instead of the industrial norms and stipulations stated in the operating instructions and applicable in Europe,
you must comply with the valid and applicable regulations in the country of utilization if the device is used
outside of the area of application.

/ 25 www.ziehl.de
Caution! If the operating current execution is programmed for all relays, a failure of
the control voltage or the device will not be detected.
When using as a monitoring device, the operator must ensure that this error
is detected through periodic performance tests.
We recommend programming and correspondingly evaluating at least one relay
in closed-circuit (idle) current execution.
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 Uson the side rating plate matches the mains voltage connected to the device!
7 Mounting
The device can be mounted:
•Distribution board or switch cabinet on 35 mm rails according to EN 60715

8.2 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.
VSR MIN / MAX value
During a vector-surge alarm, the trigger value is always saved as the
max. value; it is available until the max. value is deleted.
Enable input
Only in Pr 4 and 5, closed = disabled, no evaluation of voltage,
frequency and vector surge
Delay Enable On time
Only in Pr 4 and 5, expires while starting the unit and after opening the
Enable input; during this time, no evaluation of voltage, frequency and
vector surge takes place
Reset delay
If an alarm is present while disconnecting the control voltage, after
reconnection the programmed reset delay, 8dof 8, runs out for the
respective alarm; whenever a reset delay time 8dof 8is expiring, it is
counted down in the display (shortest first)
Reset
Use the Reset key or interrupt the control voltage for > 5 s (comply
with reset delay)
Alarm-counter
The UFR records max. 50 alarms/relay (reason, measured value).
When only 1 alarm is used (function Fun off at AL2U and AL2F, 100
alarms are stored. In the memory with the highest number, the last
alarm is stored. LEDs show the reason of the alarm and the relay. The
7-segment-display shows the value, that has caused the alarm. At
overflow all memories are deleted.
Added Time of Alarm
The added time of alarms shows for every alarm, how long the relay
has been switched off because a limit had been exceeded. The
resolution of the record is 1 minute. Time is only added as long as
supply-voltage is applied. Readout in display mode under Ac. Up =
added time of alarms TAL, Down = alarm-counter Ac xx…Ac00

9.1 Program setup
The suitable program must be set on the UFR 1001 in accordance with the application (see table). That is
taken care of during commissioning. If the UFR 1001 is sealed/locked (LED illuminated), it is not possible
to change the set program.

The value of a parameter can be set in the configuration mode. The display continually alternates between
the parameter name and the currently set value until the Up/Down key is pressed, which changes the
value of the parameter. If no key is pressed for 2 s, the display starts alternating again.
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)

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 Code /off appears in the
display.
9.10 Sealing
All the settings and the simulation mode can be locked.
If the LED is illuminated, the UFR 1001 is locked.
If an attempt is made in the locked state to change a setting, the display shows 8LOc 8for 3s.
Adjustment procedure Sealing/Lock ON (OFF):
•If present, remove seal (only authorised person)
•Slightly lift the key cover and turn 180°
•Keep keys pressed by pushing on the key cover (locked - LED flashes) until Locked –
LED is permanently OFF (ON)
