I
Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally
restarted.
• Verify isolation from the supply.
• Earth and short circuit.
• Cover or enclose neighbouring units that
are live.
• Follow the operating and installation
instructions of the device concerned.
• Only suitably qualified personnel in
accordance with EN 50110-1/-2
(VDE 0105 Part 100) may work on this
device/system.
• Before installation and before touching
the device ensure that you are free of
electrostatic charge.
• The functional earth (FE) must be
connected to the protective earth (PE) or
to the potential equalisation. The system
installer is responsible for implementing
this connection.
• Connecting cables and signal lines should
be installed in such a way that inductive or
capacitive interference does 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 60364-4-41 (VDE 0100 Part 410) 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.
•Emergencystopdevices complying with
IEC/EN 60204-1 must be effective in all
operating modes of the automation
devices. Unlatching the emergency-stop
devices must not cause 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.

Warning!
Dangerous electrical voltage!

II
• 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.
• Wherever faults in the automation system
may cause damage to persons or property,
external measures must be implemented to
ensure a safe operating state in the event
of a fault or malfunction (for example, by
means of separate limit switches,
mechanical interlocks etc.).

About this manual
This manual describes the installation, commissioning and
programming (circuit diagram generation) of the display
system.
Specialist electrical training is needed for commissioning and
creating circuit diagrams. When controlling active
components such as motors or pressure cylinders, parts of
the system can be damaged and persons put at risk if the
display system is connected or programmed incorrectly.
Device designation This manual uses the following abbreviated designations for
different device models:
• Display system
• CL-AC2 for CL-LER.18AC2
• CL-DC2 for CL-LER.18DC2, CL-LET.20DC2
Reading conventions Symbols used in this manual have the following meanings:
XIndicates actions to be taken.
hAttention!
Warns of the risk of material damage.
iCaution!
Warns of the possibility of serious damage and slight
injury.
jWarning!
Indicates the risk of major damage to property, or serious
or fatal injury.
hDraws your attention to interesting tips and
supplementary information.

1 Display system
Intended users The display system must only be installed and connected up
by trained electricians or other persons who are familiar with
the installation of electrical equipment.
Specialist electrical training is needed for commissioning and
creating circuit diagrams. When active components such as
motors or pressure cylinders are controlled, parts of the
system can be damaged and persons put at risk if the display
system is connected or programmed incorrectly.
Proper use The display system is a programmable HMI, switching
closed-loop and open-loop control device for replacing relay
and contactor controls as well as for use as an HMI unit. The
display system must be properly installed before use.
The display module of the display system is protected to
IP 65 and does not normally need any special housing
protection. The rear units of the display system are designed
as mounting units and must be installed in an enclosure,
control cabinet or a service distribution board. Both the
power feed and the signal terminals must be laid and
covered so as to prevent accidental contact.
The installation must comply with regulations for
electromagnetic compatibility (EMC).
The power up of the display system must not cause any
hazards arising from activated devices, such as unexpected
motor startups or power ups.
Improper use
The display system should not be used as a substitute for
safety-related controls such as burner or crane controls,
emergency-stop or two-hand safety controls.

Display system

1SVC 440 795 M1100
Overview The display system is an electronic display and operating
device as well as a logic relay with the following:
• Logic frunctions,
• Timing relay and counter functions,
• Time switch functions,
• Arithmetic functions,
• PID controllers,
• Operator and display functions.
The display system is a control and input device rolled into
one. The display system allows you to implement many
different tasks in domestic applications as well as in machine
building and plant construction. The display system is a
modular and flexible device.
The integrated CL-NET network allows up to eight CL-NET
stations to be connected to a controller. Each CL-NET station
can contain a program. In this way, high speed control
systems with remote intelligence can be created.
In Terminal mode, the display system can be used to control
any device in the network and display data from it. The
display system makes its keypad and display available to the
other device for use.
Two display systems can be connected simply via the serial
interfaces.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the display system
display. For example, you can:
• Connect N/O and N/C contacts in series and in parallel
• Connect output relays and markers,
• Define outputs as coils, impulse relays, rising or falling
edge-triggered relays or as latching relays,
• Select timing relays with different functions:
–On-delayed
– On-delayed with random switching,
–Off-delayed,

Overview

– Off-delayed with random switching,
– On- and off-delayed,
– On- and off-delayed with random switching,
– Single pulse,
– Synchronous flashing,
– Asynchronous flashing.
• Use up and down counters,
• Count high-speed signals:
– Up/down counters with upper and lower limit value,
– Preset,
– Frequency counters,
– High-speed counters,
– Count incremental encoder values.
•Comparevalues,
• Display graphics, texts, variables, enter setpoints, display
flashing values and graphics, change and replace graphics
and texts by pushbutton,
• Process analog inputs and outputs,
• Use 7-day and year time switches,
• Count operating hours (operating hours counter),
• Communicate via the integrated CL-NET network,
• Set up point-to-point communication via the serial
interface,
• Implement closed-loop control with P, PI and PID
controllers,
• Scale arithmetic values,
• Output manipulated variables as pulse-width modulated
signals,
• Run arithmetic functions:
–Add,
–Subtract,
–Multiply,
– Divide.
• Track the flow of current in the circuit diagram
• Load, save and password-protect circuit diagrams

If you prefer to wire up the display system from a PC, then
use the CL-SOFT programming tool. This software is used to
create and test your circuit diagram on the PC. All display
and operator functions on the display system device are
created exclusively using CL-SOFT. CL-SOFT enables you to
print out your circuit diagram in DIN, ANSI or CL format.
