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 logic relays
CL-LSR/CL-LST and CL-LMR/CL-LMT.
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
logic relay is connected or programmed incorrectly.

1 Logic relay
Intended users The logic relay must only be installed and wired up by trained
electricians or other persons familiar with the installation of
electrical equipment.
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
logic relay is connected or programmed incorrectly.
Proper use The logic relay is a programmable switching and control
device and is used as a replacement for relay and contactor
control circuits. The logic relay must be properly installed
before use.
• The logic relay is designed to be installed in an enclosure,
switch cabinet or 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 logic relay must not cause any
hazards arising from activated devices, such as
unexpected motor startups or power ups.
Improper use
The logic relay should not be used as a substitute for
safety-related controls such as burner or crane controls,
emergency-stop or two-hand safety controls.

The logic relay is an electronic control relay with logic
functions, timer, counter and time switch functions. It is also
a control and input device rolled into one. With the logic
relay you can create solutions for domestic applications as
well as for tasks in machine and plant construction.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the CL display.

For example, you can:
• Connect n/o and n/c contacts in series and in parallel
• Connect output relays and markers,
• Use outputs as relays, impulse relays or latching relays
• Use multi-function timing relays with different functions
• Use up and down counters
• Count high-speed counter pulses
• Measure frequencies
• Process analog inputs, CL-AC1, CL-DC1, CL-DC2,
(CL-LSR/CL-LST: two analog inputs, CL-LMR/CL-LMT:
four analog inputs)
• Display any texts with variables, enter setpoints
• Use year time switches, 7-day time switches CL-...C(X)...
• Count operating hours (four retentive operating hours
counters integrated)
• Track the flow of current in the circuit diagram
• Load, save and password-protect circuit diagrams
To wire the logic relay via your PC use the CL-SOFT
programming software. This software is used to create and
test your circuit diagram on the PC. CL-SOFT enables you to
print out your circuit diagram in DIN, ANSI or CL format.
