4 Application and brief description
The SW32V voltage relay is a high-quality voltage monitor with a large measurement range for monitoring
direct, alternating and three-phase networks for overvoltage and/or undervoltage. In three-phase current
networks, phase symmetry and phase sequence can be monitored in addition.
The limits are set in volts. That allows using the unit with various rated voltages.
The digital display is used to display the measurements and to precisely set limits, response times and
functions.
5 Summary of the functions
For use as a voltage monitor in energy generation and distribution plants, especially in-plant systems such
as PV plants or combined heat and power plants.
Voltage monitoring in machines and plants to prevent errors, damage or failures in sensitive equipment or
devices.
•Voltage monitoring in direct current networks DC 10.0…600 V
•Voltage monitoring in alternating current networks AC 15.0…480 V
•Voltage monitoring in three-phase current networks with//without N up to 3AC 830 V, asymmetrical
and phase failure monitoring connectible
•Preset programs for grid- and plant protection according to bdew directive (medium voltage)
•Real root mean square measurement (for AC, both half waves)
•2 Alarms/output relays, 1 each change-over contact
•Alarm and reset delay for every limit value can be individually set
•Setting of limits and hysteresis in volts
•Measurement value simulation to check the settings
•Code lock can be enabled
•Control voltage AC/DC 24-270 V
•Distributor housing for panel mounting, 4 TE (70 mm), front-to-back size 55 mm
•Mounting on 35 mm mounting rails DIN EN 60715

7 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 to the device 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 utilisation if the device
is used outside of the area of application.
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.
8 Mounting
The device can be mounted:
•Distribution board or switch cabinet on 35 mm rails 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 Uson the side rating plate matches the mains voltage connected to the device!

Explanation
Display mode 8Scn8
In programs with multiple display values, there is a switchover into the
automatic display mode after the last display value, which is indicated
by the display of 8scn8.
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). After triggering, the trip value is still available after the control
voltage is switched off.
Reset delay
After applying the control voltage, for K1 the reset delay set in 8A1_8
and for K2 the reset delay set in 8A2_8counts down. All alarms,
excepting during false phase sequence, are suppressed during this
time. During this time, the relay remains dropped out, which excludes
a temporary line fault upon starting.
Reset
Use the Reset key or interrupt the control voltage for > 5 s (comply
with reset delay)

Simulation
You can simulate a measurement and test the setting here. All 3 phases are simulated simultaneously. All
device functions 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 Up or Down key. If the SW32V
is locked, simulation is not possible.

Adjustment process:
•Select the menu item with the Up/Down key until…
Display 8si 8(Simulation)
•Press the Set key
•A voltage value can be simulated with the Up and Down keys (voltage = most recently
set value)
•Press the Set key (exits the configuration mode)
Display 8si 8(Simulation)
After exiting the Simulation menu item with the Up/Down keys, the unit switches over to monitoring the
limits.
If no key is pressed for 15 minutes, the device automatically switches back to the display mode.
Code lock
Here, the set parameters can be protected by activating a code lock.
The device acknowledges an incorrect entry with 8err8(flashes three times).
Adjustment process:
•Select the menu item with the Up/Down key until…
Display 8Cod.8(Code lock)
•Press the Set key
Display 8Pin8/ 808(Pin / Pin code) flash alternately
•Use the Up and Down keys to set the saved pin code (factory setting is 85048)
•Press the Set key
•Set the desired code lock using the Up and Down keys:
o8off.8off, all parameters can be changed
o8On8on, no parameters can be changed
•Press the Set key
Display 8Pin8/ 85048(Pin / Pin code) flash alternately
•Set the desired new pin code with the Up and Down keys
(caution: write down the pin code)
•Press the Set key
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 8Cod8/ 8off8appears in
the display.

11 Maintenance and repair
The SW32V is maintenance-free. If necessary, periodically test for proper functioning.
12 Troubleshooting and measures
Fault
Cause
Remedy
8EEE or 8-EE8appears
in the display
Measurement is
above/below range
Measured voltage is too large or too small;
comply with measurement range
8Er8appears in the
display
Limit error
8U1_8> 8U1:8
8U2_8> 8U2:8
Upper limit must be larger than lower limit
8Er9 appears in the
display
Parameter error, internal
error
Switch unit on and off, if necessary, rest to
factory settings. If the error message
continues, send the unit back to the factory
for repair.
The device cannot be
configured
Code lock
The code lock provides protection against
unauthorised manipulations on the device. If
the code lock is active, the parameters cannot
be changed. The pin can be set by the user.
Pin code unknown? -> Perform a code reset:
▪While switching on the control voltage,
keep the "Set" key pressed for 2 s
The display alternates 88888–8Cod8
–8off8–88888
Release the Set key
Code lock is switched off, Pin code = 504
