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
accordancewithEN50110-1/-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
installerisresponsibleforimplementingthis
connection.
• Connecting cables and signal lines should
be installed so that inductive or capacitive
interferencedoesnotimpairtheautomation
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/Ointerfacesothatalineorwirebreakage
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(VDE0100Part410)orHD
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.
Eaton Safety instructions
Warning!
Dangerous electrical voltage!

• Emergency stop devices complying with
IEC/EN 60204-1 must be effective in all
operatingmodesoftheautomationdevices.
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,
externalmeasuresmust beimplementedto

a fault or malfunction (for example, by
means of separate limit switches,

About This Manual
This manual describes the installation, commissioning and
programming (circuit diagram generation) of the EZD control
relay.
Aspecialist knowledgeof electrical engineeringis 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 EZD device is connected or programmed
incorrectly.
Device designation This manual uses the following abbreviated designations for
different device models:
•EZD
• EZ-AC for EZ618-AC-RE
• EZ-DC for EZ6..-DC-.E
Writing conventions Symbols used in this manual have the following meanings:
XIndicates actions to be taken.
Attention!
Warns of the possibility of light damage.
Caution!
Warnsof thepossibility ofserious damageandslight injury.
Warning!
Warns of the possibility of substantial damage, serious
injury or death.

Target readership EZD must only be installed and wired up by trained
electricians or other persons familiar with the installation of
electrical equipment.
Aspecialist knowledgeof electrical engineeringis 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 EZD is connected or programmed incorrectly.
Proper use EZD is a programmable device that provides HMI, switching,
closed-loopandopen-loopcontrolfunctions,andcanbeused
to replace relay and contactor controls as well as being used
asanEZDdevice.EZDmustbeproperlyinstalledbeforeuse.
ThedisplayandoperatingunitoftheEZDisprotectedtoIP65
anddoesnotnormallyrequireanyspecialhousingprotection.
Therear EZD units are designedas mounting units andmust
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).

Overview EZD is an electronic HMI unit and control relay with the
following features:
• Logic functions,
• Timing relay and counter functions,
• Time switch functions,
• Arithmetic functions,
• PID controllers,
• Operator and display functions.
EZD is a display, HMI, control and input device in one. With
EZD you can create solutions for domestic applications as
well as for tasks in machine and plant construction. EZD is a
modular and flexible device.
TheintegralEZ-NETnetworkenables theconnectionofupto
eight EZ-NET stations to form a single control system. Each
EZ-NETstationcancontainaprogram.Thisallowsthedesign
of systems using high-speed controllers with decentralized
intelligence.
InTerminalmode, theEZD canbe usedto controlany device
inthe network and displaydata from it, regardlessofwhether
it is an EZ800 or an EZD. In this mode, the EZD makes its
keypad and display available to the other device for use.
Two devices, EZD with EZ800 or EZD, can be connected
simply via the serial interfaces.
Circuit diagrams are connected up using ladder diagrams,
andeach element is entereddirectlyvia the EZD 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.
• use up and down counters,
• count high-speed signals:
– upanddowncounterswithupperandlower limit values,
–preset,
– frequency counters,
– high-speed counters,
– count incremental encoder values.
• compare values,
• display graphics, texts, variables, enter setpoints, display
flashingvaluesandgraphics,changeand replacegraphics
and texts by pushbutton,
• 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,
• setup point-to-point communication via the serialinterface,
• 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 EZD from a PC, then use EZSoft.
EZSoft allows you to create and test your circuit diagram on
the PC. All display and operator functions on the EZD device
are created exclusively using the EZSoft software. EZSoft is
also used to print out your circuit diagramin DIN, ANSI or EZ
format.
