3 Product description
The AD-LU 60 FE and its variants is a measurement and display unit for front panel
mounting. It measures all values in the three-phase network with neutral conductors.
For correct measurement, the current must be detected in each phase directly or via a
current transformer. See chapter ??. The power cables must be looped to the device
via a plug-in current transformer.
The measured values are displayed in color on a graphical TFT display and are divided
into different displays. They can be scrolled through manually or time-controlled.
There is a basic variant as a pure display device and variants with Modbus interface
and digital outputs for counting pulses or limit values.
The device parameters such as the currents of the connected current transformers can
be achieved via a menu on the device itself or via the optional RS-485 interface.

GND
The measuring voltages are divided by a voltage divider (1) and fed to the analog-
to-digital converter (4). The AC/DC converter (3) is simultaneously fed from the
measuring voltages. The AC / DC converter (3) supplies the analog-to-digital con-
verter (4) on the input side and the circuits on the output side.
The currents are first fed via the ring core current transformer (10) present on the
outside of the device. The mA signals on the secondary side are measured via shunts
(2) and are also fed to the analog-to-digital converter (4).
The analog-to-digital converter (4) transmits all raw data to the output side via a
galvanic separation (5). Here, they are scaled by the microcontroller (6) to the power
values, currents, voltages, etc. The scaled values are displayed on the display (7). For
the device variants with RS-485 interface (8), these values can also be read out via
the Modbus protocol. With the device variants with open-collector output (9), limits
8

or pulses can also be output.
3.5 Update rates
All measured values are recorded in a fixed time interval of 0.5s. The display output
is updated once per second.
3.6 Behavior of the device in the event of a fault
The AD-LU 60 FE verifies whether the signal voltage is present on phase L1. If this
is not the case, the AD-LU 60 FE goes into the error state. The device variants
AD-LU 60 FE-D, AD-LU 60 FE-DB switch off their outputs, ie the transistors are not
conductive.
3.7 Display and control elements
TFT-Display
Up SetDown
The AD-LU 60 FE has a color-coded TFT display for displaying the data and three
buttons for operation and configuration.

to the destruction of the output.
10

4.4 RS-485 Interface
The variants AD-LU 60 FE-B, AD-LU 60 FE-DB also have an RS-485 interface.
The connection to the other devices must be established via a twisted shielded bus
cable. The order of the devices among each other is arbitrary. For reasons of electro-
magnetic compatibility, the shield is to be connected at both ends to a large area and
to be connected with a protective shield. The wiring must be in a bus structure. Stops
longer than 5 m should be avoided. The two ends of the bus line must be terminated
with a resistance of 120 ohms, especially with longer bus lines.
If the device is to be operated in a bus segment that already has devices other than
Modbus slaves, the baud rate, parity and slave address may need to be adjusted. These
settings can be made directly from the device menu.

5 Installation and commissioning
HAZARD Danger to life by electric shock
The terminals of the voltage inputs are hazardous to contact.
•Disconnect power supply
•Check absence of voltage
•Insert the device into the intended opening of the front panel
•Connect the power inputs and RS-485 interface
•Lead current carrying wires by the current transformer on the rear panel
•Switch on the voltage
•Configure the device from the menu or Configuration program AD-Studio
•Check function
•Disconnect power supply
•Connect digital outputs 1
•Reconnect power supply
•Check current through the current transformers
1The Open-Collector outputs should be connected after the function test in order to avoid unwanted
switching or fault messages.
INFO Observe the current conductor K/L via the current transformers
When passing through the current transformers on the rear side,
the energy flow direction from K to L must be taken into account.
K = infeed side, L = load side. See also the chapter ??. If you
do not have a PV system installed that feeds energy back into
the grid, all the active powers must be positive. Please check
this in the relevant display. When e.g. The value for the active
power in L2 is negative, the current conductor for I2 is probably
wrongly inserted by the current transformer.

7 Configuration
The parameters of the AD-LU 60 FE-B, AD-LU 60 FE-DB in chapter 7.2 can be se-
lected via the device menu itself or with the Configuration program AD-Studio . The
values in the chapter ??. Can be read, viewed or logged. This can be very helpful
especially during commissioning.
For the AD-LU 60 FE and the AD-LU 60 FE -D, the parameters can only be set on
the device menu itself.
7.1 Symbols
The following symbols are used.
P1 ... P3 Active powers in phases L1 ... L3 in kW.
Q1 ... Q3 Reactive powers in phases L1 ... L3 in kvar.
S1 ... S3 Apparent powers in the phases L1 ... L3 kVA.
Ptotal Total active power in phases L1 ... L3 in kW.
Qtotal Total reactive power in phases L1 ... L3 in kvar.
Stotal Total apparent power in phases L1 ... L3 kVA.
I1 ... I3 Currents in phases L1 ... L3 in A.
U1 ... U3 Voltages in the phases L1 ... L3 in V.
FFrequency in phase L1 in Hz.
PF1 ... PF3 Power factor in phases L1 ... L3. PFn =|P n|/Sn.
PFtotal Power factor of the entire phases in the network. P Ftotal =|Ptotal |/Stotal.
7.2 Parameters
This is followed by a reference to the parameter that can be changed via the menu on
the device or by the Configuration program AD-Studio . The table columns have the
following meaning.
Name Parameter name as found in the configuration program.
Default value In the delivery state and after setting the factory settings, the param-
eter has this value.
18

Valid Range Limits for the smallest and largest input value. For lists, a list of all
elements.
Unit Physical unit of the value.
Comments Comments or explanations.
7.2.1 Current and voltage transformers
The current and voltage converters, which are connected to the AD-LU 60 FE , are
taken into account in the calculation of the currents, voltages, power and counter and
must be known.
Name Default Range Unit
Primary current 5 1 ... 10000 A
Secondary current 5 1 ... 20 A
Primary voltage 230 50 ... 500000 V
Secondary voltage 230 50 ... 500 V
7.2.2 Filter
All measured values are filtered. The larger the filter number, the higher the effect of
the attenuation. Each measured value is filtered according to the following relationship.
Mt=Mt−1+Mt−Mt−1
F
where
•MtMeasured value at time t.
•Mt−1Measured value at time t-1, ie the last measured value.
•FValue of the filter number.
A filter number of 1 returns the current measured value unfiltered. A filter number of
2 gives the arithmetic mean value between the current and the last measured value.
The measured values are cyclically filtered. The attenuation depends on the cycle time
and the filter number. The timing is explained in chapter ??.
The relationship between settling time, cycle time and filter number is
t90 =F∗2,26 ∗tz
where
•t90 Settling time of the filtered measured value to 90 % with a signal change in
the input from 0 to 100 %.
•tzCycle time in seconds.
The desired settling time t90 can be entered directly in seconds as a parameter for
filtering the signals. The AD-LU 60 FE calculates the filter number from the settling
time and the sampling rate itself.
