Caution!
Dangerous electrical voltage!
Before commencing the installation
●Disconnect the power supply of the
device.
●Ensure that the device cannot be
accidentally restarted.
●Verify isolation from the supply.
●Earth and short circuit.
●Cover or enclose neighbouring units that
are live.
●Follow the engineering instructions
(AWA) of the device concerned.
●Only suitably qualified personnel may
work on this device/system.
●Before installation and before touching
the device ensure that you are free of
electrostatic charge.
●Connecting cables and signal lines
should be installed so that inductive or
capacitive interference do not impair the
automation functions.
●Install automation devices and related
operating elements in such a way that
they are well protected against
unintentional operation.
●Suitable safety hardware and software
measures should be implemented for
the I/O interface so that a line or wire
breakage on the signal side does not
result in undefined states in the
automation devices.
●Ensure a reliable electrical isolation of
the low voltage for the 24 volt supply.
Only use power supply units complying
with IEC 60 364-4-41 or HD 384.4.41 S2.
●Deviations of the mains voltage from the
rated value must not exceed the
tolerance limits given in the
specifications, otherwise this may cause
malfunction and dangerous operation.
●Emergency stop devices complying with
IEC/EN 60 204-1 must be effective in all
operating modes of the automation
devices. Unlatching the emergency-stop
devices must not cause uncontrolled
operation or restart.
●Devices that are designed for mounting
in housings or control cabinets must only
be operated and controlled after they
have been installed with the housing
closed. Desktop or portable units must
only be operated and controlled in
enclosed housings.
●Measures should be taken to ensure the
proper restart of programs interrupted
after a voltage dip or failure. This should
not cause dangerous operating states
even for a short time. If necessary,
emergency-stop devices should be
implemented.

1 About the LCD Keypad
System overview The DE 4-KEY-2 LCD keypad has the following type
code:
The optional LCD keypad DE4 4-KEY-2 can be used
to configure drive controllers to your specific require-
ments.
With the function keys, you enter the desired param-
eters to control the drive. The actual values and
status messages are shown on the display.
The set parameters can be saved in the LCD keypad,
from where they can be copied to other drive control-
lers. To copy parameters, specific codes must be
executed. These are described in the drive controller
manuals.
The keypad is hot-pluggable, i.e. it can be connected
and disconnected while the keypad and drive
controller are switched on.
The drive controller can also be started and stopped
using the keypad.

4 Operation/Displays
Example for the DM
soft starter
왘Connect the LCD keypad to the DM 4 soft starter
왘Switch on the controlled device.
The LCD keypad now performs a self test. When the
test is completed, the display changes from “Init” to
the first parameter in the first menu.
The LCD keypad is now in operation mode, which is
indicated by the blank “active menu mode” (see
diagram on page 10) field. On the menu/parameter
text line, a default display parameter now appears,
which depends on the connected device. Only a
value is displayed here; the parameter name and
number do not appear. Refer to the documentation
for the controlled device to determine whether the
displayed value is adjustable or fixed, and which
parameter is being displayed.
The illustrations below are examples of the
display screens and parameters of the soft starter
DM 4. Names, parameter numbers and values
may differ for other devices.

Figure 2: Operation mode
To change or view parameters, change to Program-
ming mode.
왘Press the PRG key once, to change from opera-
tion mode to menu mode.
If the current menu does not contain any submenus,
the LCD keypad changes directly from menu mode
to parameter mode.

왘Use the cursor keys (䉱, 䉲, 䉳, 䉴) to navigate
within the menu and parameter modes and to find
the required parameter.
In menu mode, the main menu items appear on the
parameter value line, which may also contain
submenus. The parameters are displayed in the main
menu item or, if submenus are shown, only in the
submenu. The names of submenus and parameters
are shown on the menu/parameter text line.
In parameter mode, the parameter is shown in the
display’s two bottom lines; the text content depends
on the parameter type. For simple parameters, the
menu/parameter text line contains the parameter
name, while the parameter value line shows the
associated value.
Figure 4: Parameter name with value
Parameters of type “Text” contain a text string (e.g.
device type, se eFig .3). Parameters with predefined
text strings for selection can also show text strings
assigned to a parameter value.

When the correct parameter appears on the display,
왘press the PRG key to change from parameter
mode to programming mode.
The cursor now appears on the display’s parameter
value line.
Figure 5: Programming mode
The values of all parameters allowing write access
can be edited with the cursor keys.
왘To increase the value, press (䉱), to reduce it,
press (䉲), and to change the cursor position,
press 䉳/䉴.
If the current parameter is a selection parameter, the
last line of the display changes to show the function
associated with the selected value.
Using as an example the "Operating mode" param-
eter of the DM 4, the display appears as shown
below:
0 = Standard
1 = In-Delta
2 = Controller
3 = Phase controller

In programming mode, the value (0 to 3) appears on
the parameter value line, and the function (e.g. “In-
Delta”) in place of the parameter name on the menu/
parameter text line. To change to programming
mode, press PRG.

Selection parameters include the bit parameters
(e.g. status information, functio non/off). For these
parameters, the name and the current numeric value
(0 o 1) are displayed.
왘To view the associated bit status text in the
menu/parameter text line (e.g. On/Off, Disable/
Continue), press PRG.
왘Press SHIFT + PRG to save the entered param-
eter value.
or
왘To cancel the change, press PRG.
When SHIFT + PRG or PRG is pressed, the display
returns to operation mode and shows the first
parameter in the first menu again.
Parameters that are accepted online (i.e. as soon as
they are entered), do not need to be saved. To
confirm the input, just press PRG. Instead of the first
parameter in the first menu, the currently selected
parameter will continue to be displayed. As for the
other parameters, the default display parameter
appears on the menu/parameter text line.
