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.

• Short circuit to earth.

• Cover or enclose neighboring 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 equalization. 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.

• 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.).

1 EZ800 Control Relay

Target readership EZ must only be installed and wired up by trained electricians

or other persons familiar with the installation of electrical
equipment.

A specialist knowledge of electrical engineering 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 EZ is connected or programmed incorrectly.

Proper use EZ is a programmable switching and control device and is

used as a replacement for relay and contactor control circuits.
EZ must be properly installed before use.

EZ 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 conform to regulations for
electromagnetic compatibility (EMC).

The power up of the EZ must not cause any hazards arising
from activated devices, such as unexpected motor startups or
power ups.

Improper use

EZ should not be used as a substitute for safety-related
controls such as burner or crane controls, emergency-stop or
two-hand safety controls.

EZ800 Control Relay

Overview EZ800 Control Relay is an electronic control relay with:

• Logic functions,

• Timing relay and counter functions,

• Time switch functions

• Arithmetic functions

• PID controllers

• Operator and display functions

EZ800 Control Relay is a control and input device rolled into
one. With EZ800 Control Relay you can create solutions for
domestic applications as well as for tasks in machine and
plant construction.

The integral EZ-NET network enables the connection of up to
eight EZ-NET stations to form a single control system. Each
EZ-NET station can contain an individual circuit diagram. This
allows the design of systems using fast controllers with
decentralized intelligence.

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

• connect make and break contacts in series and in parallel

• switch output relays and auxiliary contacts,

• 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,
– off-delayed with random switching,
– on and off delayed,
– on and off delayed with random switching,
– single pulse,
– synchronous flashing,
– asynchronous flashing.

Overview

• use up and down counters,

• count high-speed signals:
– up and down counters with upper and lower limit values,
–preset,
– frequency counters,
– high-speed counters,
– count incremental encoder values.

• compare values,

• display any texts with variables, enter setpoints

• process analog input and output values (DC units),

• process additional inputs and outputs,

• use 7-day and year time switches,

• count operating hours (operating hours counter),

• communicate via the integrated EZ-NET network,

• provide 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 EZ800 Control Relay from a PC, then
use EZSoft. EZSoft allows you to create and test your circuit
diagram on the PC. EZSoft enables you to print out your
circuit diagram in DIN, ANSI or EZ format.

2Installation

The EZ must only be installed and wired up by qualified
electricians or other persons familiar with the installation of
electrical equipment.

Danger of electric shock!

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

Always follow the safety rules:

• Switch off and isolate,

• Ensure that the device is no longer live,

• Short-circuit and ground,

• Cover adjacent live parts.

The EZ is installed in the following order:

• Mounting,

• Wiring up the inputs,

• Wiring up the outputs,

• Wiring up the NET network (if required),

• Connecting the power supply.

Mounting Install EZ in an enclosure, switch cabinet or distribution board

so that the power feed and terminal connections cannot be
touched accidentally during operation.

Snap EZ onto a IEC/EN 60715 top-hat rail or fix EZ in place
using fixing brackets. EZ can be mounted vertically or
horizontally.

The following applies to expansion units:
With longer cables, connect a diode (e.g. 1N4007) for 1 A,
minimum 1 000 V reverse voltage, in series to the EZ input.
Ensure that the diode is pointing towards the input as shown

Caution!

Do not use reed relay contacts on 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

• I8 = IA02

• I11 = IA03

Caution!

Analog signals are more sensitive to interference than
digital signals. Consequently, more care must be taken
when laying and connecting the signal lines. Incorrect
switching states may occur if they are not connected
correctly.

XUse shielded twisted pair cables to prevent interference

with the analog signals.

XFor 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 equalization
currents between the two grounding points and thus in the

XDo not lay signal lines parallel to power cables.
XConnect inductive loads to be switched via the EZ 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 EZ via the same power

suppressor circuits are best connected directly in the
proximity of the inductive load.

If inductive loads are not suppressed, the following applies:
Several inductive loads should not be switched off

In RUN mode EZ continuously processes a stored circuit
diagram until you select STOP or disconnect the power. The
circuit diagram, parameters and the EZ settings are retained
in the event of a power failure. All you will have to do is reset
the real-time clock after the back-up time has elapsed.Circuit
diagram entry is only possible in STOP mode.

Caution!

In RUN mode, EZ will immediately run the program saved
in the unit when the power supply is switched on. This will
not happen if STOP mode was set as startup mode. In RUN
mode outputs are activated according to the switch logic
involved.

The following applies to devices without display/operating
unit:

Creating your first circuit
diagram

The following single line diagram takes you step by step
through wiring up your first circuit diagram. In this way you will
learn all the rules, quickly enabling you to use EZ for your own
projects.

As with conventional wiring, you use contacts and relays in
the EZ diagram. With EZ, however, you no longer have to
connect up components individually. At the push of a few
buttons, the EZ circuit diagram produces all the wiring
required. All you have to do is then connect any switches,
sensors, lamps or contactors you wish to use.

EZ800 Control Relay operation

Program

A program is a sequence of commands which the EZ800
Control Relay executes cyclically in RUN mode. An EZ800
Control Relay program consists of the necessary settings for
the device, EZ-NET, password, system settings, a circuit
diagram and/or function blocks.

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 blocks

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

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

Relays

Relays are switching devices which are electronically
simulated in EZ800 Control Relay. They actuate their contacts
according to their designated function. A relay consists of a
coil and at least one contact.

Contacts

You modify the current flow with the contacts in the EZ800
Control Relay circuit diagram. Contacts such as make
contacts carry a 1 signal when closed and 0 when open. Every
contact in the EZ800 Control Relay circuit diagram can be
defined as either a make contact or a break contact.

Contact

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.

Wiring with EZ800

Circuit diagram display

In the EZ800 Control Relay circuit diagram, contacts and coils
of relays 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 circuit
connections. It is then wired up with connections.

• Insert contacts in the four contact fields. The first contact

field on the left is automatically connected to the voltage.

• Insert the relay coil to be controlled together with its function

and designation in the coil field. The coil designation
consists of the coil name, coil number and function block
from the function designation. The coil function defines the
method of operation of the coil.

• Every line in the circuit diagram forms a rung. With the

EZ800 Control Relay up to 256 circuit connections can be
wired in a circuit diagram
