The multimess F144-0-LED-...-5 is an aordable network measuring device for
switchboard installation that measures all important parameters in three-phase
networks.
The microprocessor of the multimess F144-0-LED-...-5 records the mains volt-
age and current consumption of the meter point for all three phases via analog/
digital converter inputs and calculates the active, reactive and apparent power
ratio in the three-phase network.
Convenient operation and display
The LED displays L1, L2 and L3 allow you to read the measured values directly
and enter the respective parameters and conguration data. In addition, eleven
LEDs indicate menus and the status. Six sensor buttons facilitate navigation
through the menus.
For 100 to 400V networks
The multimess F144-0-LED-...-5 can be used in 3-wire and 4-wire networks. The
device can be used to make measurements directly in 100 V and 400V net-
works. Higher voltages can only be connected via external voltage transform-
ers, with the primary and secondary voltage being programmable. The measur-
ing voltage inputs of the device measure directly, i.e. they are not galvanically
separated by a voltage transformer!
For energy supply networks with an outer conductor to ground potential,
suitable ballasts with electrical isolation must be used, e.g. voltage transformers
or zero point creators.
x/5A or x/1A freely programmable
The current measurement inputs must always be supplied via current trans-
formers; the transformer ratio is programmable. The primary current value as
well as the secondary current value can be selected.
Determining the neutral conductor current

Rev. 5.00
24314_EDEBDA0263-1419-1_EN
13
KBR multimess F144-0-LED-...-5Field of application / range of functions
The neutral conductor current is either calculated or measured by an additional
connected transformer and shown on the display.
Calculating the PE leakage
When the neutral conductor current is measured, the PE leakage is calculated
and displayed. When the neutral conductor current is calculated, no PE leakage
is displayed.
Harmonic analysis
Harmonic analysis by Fourier transform. The multimess F144-0-LED-...-5 mea-
sures the harmonics of the 3rd / 5th / 7th / 9th / 11th / 13th / 15th / 17th and
19th up to 63rd. Voltage network harmonic, calculates their partial harmonic
content and the total distortion factor of the voltage.
Two-tari meter function (HT/LT)
Consumption during high tari and low tari times is recorded separately.
Switching from high to low tari and back again is done by the internal clock.
Programmable pulse output
Active energy or reactive energy proportional pulses can be output via a
programmable output laid out as an S0compatible interface. The pulse output
type (proportional to active or reactive energy) as well as the pulse signi-
cance (number of pulses per kWh or per kvarh) and the pulse length can be
programmed. These pulses can be processed by, for example, a master system
for data acquisition or optimization, a maximum-demand monitor or a central
process control.
Separate power supply
The device requires a separate auxiliary voltage for operation.

KBR multimess F144-0-LED-...-5Installation and electrical connection
CAUTION
Do not apply DC voltage to the voltage measurement input.
The device is not suitable for DC voltage measurement.
Attach the current transformer terminal to the device using the two screws
provided.
Never operate open external unloaded current transformers. Always short-cir-
cuit them. Risk of injury due to high voltages and electrical currents.
For the wiring of the pulse output, we recommend that you only use shielded
twisted pair cables to avoid interference (e.g. installation line I-Y(ST) Y 2 x 2 x 0.8
mm2, with the shielding only connected on one side).
During installation, please also observe our notes on safety measures against
overvoltage and lightning in the chapter "Overvoltage and lightning protec-
tion" of this manual.
NOTE
The following points must be taken into account when connecting the device
to the three-phase network you want to measure:
- Direction of energy ow
- Assignment of measuring voltage input/current transformer input
Rotary eld:
The device can be operated with a clockwise or anti-clockwise rotary eld.
When switching on the device power supply, the multimess
F144-0-LED-...-5 automatically checks the direction of rotation. Rotary eld
check:
Only connect the measuring voltage to the device (Umeas see nameplate).
Switch the device on by connecting the power supply cable voltage to the
power supply connections (L and N). The device checks the power supply's
direction of rotation immediately after being switched on.
The rotary eld is displayed in the in the Rot.eld submenu of the UPH-PH
menu.
For a clockwise rotary eld, the display shows L1 0, L2 120 and L3 240 degrees.

Rev. 5.00
24314_EDEBDA0263-1419-1_EN
16
KBR multimess F144-0-LED-...-5 Installation and electrical connection
If you want to change the direction of rotation from clockwise to anti-clock-
wise, simply swap two terminals, i.e. two phases, then switch the device OFF
and ON again. The display now shows the correct voltage and the device
starts measuring automatically.
Check again whether the assignment of the voltage path L1 and the current
path L1 as well as all other phases are still correct.
Current transformer connection:
Direction of energy ow:
When installing the transformers, observe the direction of current ow or en-
ergy ow. If the current transformer is installed the wrong way, the sign of the
measured value will be inverted.
A prerequisite for this is that energy is supplied to the device.
Assigning the measuring voltage input / current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be installed in the phase
in which the measuring voltage for terminal 10 (L1) is measured. The same
applies to the other transformer and measuring voltage connections.
With the multimess F144-0-LED-...-5, you can check the phase sequence as
follows:
- Go to the main menu "I”
- Connect the current transformer to the corresponding wires
- If the connection and direction of energy ow are correct, the device will
only display positive currents.
- If the device is connected incorrectly, all currents displayed will be negative.
In this case, swap the connections until the display shows the correct values.
CAUTION
Before any interchanging, the current transformers must be shorted out!

Current measurement inputs
The current measurement inputs must be connected via current
transformers x/1A AC or x/5A AC.
When connecting transformers, pay attention to the direction of
energy ow and the correct assignment of measuring voltage
inputs to the current transformers.
26 (k4) and 27 (l4) Current measurement input for the neutral conductor
The current measurement input for the neutral conductor must
be connected via current transformers x/1A AC or x/5A AC.
30 and 31: Floating relay contact relay1
This contact serves as a message or alarm output. During oper-
ation, an acoustic or visual message can be activated or a con-
sumer switched o using this relay. The contact is open as long
as the device is dead as well as when there is an active message.
Maximum switching capacity 2A at 250V AC (not safe to touch).
