Warning! Dangerous electrical voltage!

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.

•Emergency stop devices 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.

Safety instructions

• 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, emergencystop 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.

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.

1SVC 440 795 M0100

Overview

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.

2 Installation

The logic relay must only be installed and wired up by trained electricians or other persons familiar with the mounting of electrical equipment.

Danger of electric shock

Mounting Install the logic relay in a control cabinet, service distribution

Never carry out electrical work on the device while the power supply is switched on.

Always follow the safety rules:

• Switch off and isolate

• Secure against reclosing

• Ensure that the device is no longer live

• Cover adjacent live parts

The logic relay is installed in the following order:

• Assemble devices if necessary

• Mounting

• Wiring up the inputs

• Wiring up the outputs

• Connecting the power supply

board or in an enclosure so that the power feed and terminal connections cannot be touched accidentally during operation.

Fit the logic relay on a top-hat rail in accordance with DIN EN 50022 or fasten the logic relay with fixing brackets. The logic relay can be mounted either vertically or horizontally.

When using the logic relay with expansion units, connect the expansion concerned before mounting (a page 30).
