Subject to alteration without notice.

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 engineering instructions (AWA) 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 so 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.

Moeller GmbH

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.).

easy is an electronic control relay with logic functions, timer, counter and time switch functions. It is also a control and input device in one that can perform many different tasks in domestic applications as well as in machine building and plant construction.

Circuit diagrams are connected up using ladder diagrams, and each element is entered directly via the easy display. For example, you can:

• Connect make and break 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, easy-AB, easy-DA, easy-DC, (EASY512..: two analog inputs, easy700: four analog inputs)

• Display any texts with variables, enter setpoints

• Use year time switches, 7-day time switches, EASY…-..-.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

Connecting the power supply

Applies to easy-AC devices with a power supply greater than 24 V AC:

• The voltage terminals for phase L and neutral conductor N have been reversed.

• This enables the easy interface (for memory card or PC connection) to have the full connection voltage of the phase conductor (100 to 240 V AC).

• There is a danger of electric shock if the connection at the easy interface is not properly connected or if conductive objects are inserted into the socket.

Attention!

A short current surge will be produced when switching on for the first time. Do not switch on easy by means of reed contacts since these may burn or melt.

Installation

05/04 AWB2528-1508GB

For longer lengths connect in series a diode (e.g. 1N4007) for 1 A, min. 1000 V reverse voltage, to the easy input. Ensure that the diode is pointing towards the input as shown in the circuit diagram, otherwise easy will not detect the 1 state.

easy-AB

easy-AC: Inputs I7 and I8 have a higher input current on the easy-AC. Neon bulbs with a maximum residual current of 2 mA/1 mA at 230 V/115 V can be connected to I7 and I8.

Always use neon bulbs that are operated with a separate N connection.

Caution!

Do not use reed relay contacts at I7, I8. These may burn or melt due to the high inrush current of I7, I8.

Two-wire proximity switches have a residual current with the “0” state. If this residual current is too high, the easy input may only detect a “1” signal.

Therefore, use inputs I7 and I8. An additional input circuit is required if more inputs are used.

Connecting easy DC analog inputs

The easy-AB, easy-DA and easy-DC basic units are provided with analog inputs. Inputs I7 and I8, and if present I11 and I12, can be used to connect analog voltages ranging from 0 V to 10 V. A simple additional circuit also allows the analog evaluation of currents from 0 to 20 mA. The analog input signals are converted to 10-bit digital signals.

The following applies:

• 0 V DC corresponds to a digital 0.

• 5 V DC corresponds to a digital value of 512.

• 10 V DC corresponds to a digital value of 1023.

05/04 AWB2528-1508GB

Connecting the inputs

Caution!

Analog signals are more sensitive to interference than digital signals. Consequently, greater care must be taken when laying and connecting the signal lines.

Incorrect switching states may occur if they are not connected correctly.

Safety measures with analog signals

X Use shielded twisted pair cables to prevent interference

with the analog signals.

X For short cable lengths, ground the shield at both ends

using a large contact area. If the cable length exceeds 30 m or so, grounding at both ends can result in equalisation currents between the two grounding points and thus in the interference of analog signals. In this case, only ground the cable at one end.

X Do not lay signal lines parallel to power cables. X Connect inductive loads to be switched via the easy

outputs to a separate power feed, or use a suppressor circuit for motors and valves. If loads such as motors, solenoid valves or contactors are operated with easy via the same power feed, switching may result in interference on the analog input signals.

The following four circuits contain examples of applications for analog value processing.

Caution!

Ensure that the reference potential is connected. Connect the 0 V of the power supply unit for the different setpoint potentiometers and sensors shown in the examples to the 0 V and neutral conductor terminal (easy-AB) of the easy power feed. Otherwise incorrect switching states may occur if they are not connected correctly.

Installation

05/04 AWB2528-1508GB

Power supply of easy-AB devices and analog inputs

With easy-AB devices that process analog signals, the device must be fed via a transformer so that the device is isolated from the mains supply. The neutral conductor and the reference potential of the DC power feed of analog sensors must be electrically connected.

Ensure that the common reference potential is grounded or monitored by a ground fault monitoring device. Observe the requirements of the relevant regulations.

Caution!

Please note the following when switching off inductive loads.

Suppressed inductive loads cause less interference in the entire electrical system. For optimum suppression the suppressor circuits are best connected directly to the inductive load.

Installation

05/04 AWB2528-1508GB

If inductive loads are not suppressed, the following applies: Several inductive loads should not be switched off simultaneously to avoid overheating the driver blocks in the worst possible case. If in the event of an emergency stop the +24 V DC power supply is to be switched off by means of a contact, and if this would mean switching off more than one controlled output with an inductive load, then you must provide suppressor circuits for these loads (see the following diagrams).

Behaviour with short-circuit/overload

Should a short circuit or overload occur on a transistor output, this output will switch off. The output will switch on up to maximum temperature after the cooling time has elapsed. This time depends on the ambient temperature and the current involved. If the fault condition persists, the output will keep switching off and on until the fault is corrected or until the power supply is switched off (a section “Monitoring of short-circuit/overload with EASY..-D.-T..”, page 242).

05/04 AWB2528-1508GB

Only one device (expansion device or bus connection) can be connected to the EASY-LINK connection.

At present, easy700 can communicate with the following bus systems or networks:

• AS-Interface (Actuator-Sensor Interface)

•Profibus-DP

•CANopen

• DeviceNET

The different bus systems offer different functions.

The following applies:

• As a minimum data exchange, the input data R1 to R16 and output data S1 to S8 can be exchanged, provided that the bus system supports this.

• If the bus system or bus gateway is capable of this, function block, date, time parameters can be read and written via the bus. The states of inputs, outputs, markers can be read.

The range and the functions of the bus gateways are being continually further developed.

The current Moeller product line catalogue and the Internet online catalogue contain those bus gateways that are currently available.

Program

A program is a sequence of commands which easy executes cyclically in RUN mode. An easy program consists of the necessary settings for the device, password, system settings, a circuit diagram and/or function relays.

05/04 AWB2528-1508GB

Operation of easy

Circuit diagram

The circuit diagram is that part of the program where the contacts are connected together. In RUN mode a coil is switched on and off in accordance with the current flow and the coil function specified.

Function relays

Function relays are program elements with special functions. Example: timing relays, time switches, counters. Function relays are elements provided with or without contacts and coils as required. In RUN mode the function relays are processed according to the circuit diagram and the results are updated accordingly.

Examples: Timing relay = function relay with contacts and coils Time switch = function relay with contacts

Relay

Relays are switching devices which are electronically simulated in easy. They actuate their contacts according to their designated function. A relay consists of at least a coil and a contact.

Contacts

You modify the current flow with the contacts in the easy circuit diagram. Contacts such as make contacts carry a 1 signal when closed and 0 when open. Every contact in the easy circuit diagram can be defined as either a make contact or a break contact.

Wiring with easy

05/04 AWB2528-1508GB

Coils

Coils are the actuating mechanisms of relays. In RUN mode, the results of the wiring are sent to the coils, which switch on or off accordingly. Coils can have seven different coil functions.

easy works with different contacts, which can be used in any order in the contact fields of the circuit diagram.

To ensure compatibility with easy400 and easy600 devices, each easy500 and easy700 is provided logically with all possible contacts. If contacts are not supported by the device, i.e. devices without a clock, their switching state is always zero. The contacts (make contact) of the time switches are always set to logic 0.

The advantage of this process is that you can use the same circuit diagram on all easy500, easy700, easy-AB, easyAC, easy-DA and easy-DC devices.

Circuit diagram display

In the easy circuit diagram, contacts and coils are connected up from left to right - from the contact to the coil. The circuit diagram is created on a hidden wiring grid containing contact fields, coil fields and rungs. It is then wired up with connections.

• You can add switch contacts in the three contact fields. Easy adds the first energized contact field automatically.

• You add the relay coil to be controlled together with its function and designation in the coil field.

• Every line in the circuit diagram forms a rung. Up to 128 rungs can be wired in a circuit diagram.

Wiring with easy

05/04 AWB2528-1508GB

The circuit diagram display performs two functions:

• In STOP mode it is used to edit the circuit diagram.

• In RUN mode it is used to check the circuit diagram using the Power flow display.

Saving and loading circuit diagrams

There are two ways of saving circuit diagrams in easy externally:

• By saving to a memory card

• By saving to a PC running EASY-SOFT-BASIC.

Once they have been saved, programs can be reloaded into easy, edited and run.

All circuit diagram data is saved in easy. In the event of a power failure the data will be retained until the next time it is overwritten or deleted.

Memory card

Each EASY-M-32K memory card contains a circuit diagram which is inserted into the easy interface. The program is stored retentively on the memory card.

The way the memory card works and a description of how to transfer a program to the card is given in section “Memory card” on page 248.

EASY-M-8K memory cards of easy400 devices can be read in easy500. EASY-M-8K memory cards of easy400 devices and easy600 EASY-M16K memory cards can be read in easy700.

Write operations from easy500 and easy700 are only possible to the EASY-M32K memory card.

EASY-SOFT-BASIC

EASY-SOFT-BASIC is a PC program with which you can create, store, test (simulate) and manage easy circuit diagrams.

05/04 AWB2528-1508GB

Working with contacts and relays

Completed circuit diagrams are transferred between your PC and easy via the connecting cable. Once you have transferred a circuit diagram, simply run easy straight from your PC.

Details on the program and transferring circuit diagrams are given in section “EASY-SOFT-BASIC” from page 252.

Working with contacts and relays

In easy circuit diagrams, the switches, buttons and relays of conventional circuit diagrams are connected up using input contacts and relay coils.

Marker relays M and N are used as a flag. The S relay can be used as the output of an expansion unit or as a marker if no expansion unit is connected. The only difference between them and the output relay Q is that they have no output terminals.

The coil functions of the function relays are described in the descriptions for the appropriate relays.

Wiring with easy

05/04 AWB2528-1508GB

The coil functions Ä, Å, è, È, (contactor, contactor

negated, cycle pulse negative, rising edge) must only be used once for each relay coil. The last coil in the circuit diagram determines the status of the relay.

When controlling a contactor or relay, the control coil is only present once. If you are creating parallel circuits, use Set, Reset as a coil function.

Rules for wiring relay coils

To ensure a clear overview of all relay states only assign the same coil function once to a relay ( retentive coil functions such as

ä, S, R). However,

ä, S, R can be used several

times if required by the circuit diagram logic.

Exception: When using jumps to structure a circuit diagram, this coil function can also be used effectively several times.

Relay with contactor function

The output signal follows immediately after the input signal and the relay acts as a contactor.

05/04 AWB2528-1508GB

Working with contacts and relays

Contactor function with negated result (inverse contactor function)

The output signal is simply an inversion of the input signal; the relay operates like a contactor with contacts that have been negated. If the coil is triggered with the 1 state, the coil switches its make contacts to the 0 state.

Falling edge evaluation (cycle pulse) è

This function is used if the coil is only meant to switch on a falling edge. With a change in the coil state from 1 to 0, the coil switches its make contacts to the 1 state for one cycle.

Physical outputs should not be used as a cycle pulse is generated.

Rising edge evaluation (cycle pulse) È

This function is used if the coil is only meant to switch on a rising edge. With a change in the coil state from 0 to 1, the coil switches its make contacts to the 1 state for one cycle.

Working with contacts and relays

Impulse relay ä

The relay coil switches whenever the input signal changes from 0 to 1. The relay behaves like an impulse relay.

Representation in easy:

• Output relays Q:

•Markers M:

äQ1 to äQ8 (depending on type)

äM1 to äM16

• Function relays (Text) D: äD1 to äD8

• Relays S: äS1 to äS8

A coil is automatically switched off if the power fails and if STOP mode is active. Exception: Retentive coils retain signal 1 (a section “Retention (non-volatile data storage)” from page 230).

Latching relay

The “latch” and “unlatch” relay functions are used in pairs. The relay picks up when latched and remains in this state until it is reset by the “unlatch” function.

I1-I2----SQ1

I2-------RQ1

AB C

Figure 45: Latching relay signal diagram

• Range A: The Set coil and the Reset coil are triggered at different times

• Range B: Reset coil is triggered at the same time as the Set coil

• Range C: Power supply switched off

Representation in easy:

• Q output relays:

SQ1 to SQ8, RQ1 to RQ8 (depending on

type)

• M markers:

SM1 to SM16, RM1 to RM16

• (Text) D function relays: SD1 to SD8, RD1 to RD8

•S relays:SS1 to SS8, RS1 to RS8

Use each of the two relay functions S and R once only per

relay.

If both coils are triggered at the same time, priority is given to the coil further down in the circuit diagram. This is shown in the above signal diagram in section B.
