Safety for people and machines

In machine production, a wide range of safety-related components such as

position switches or emergency-stop buttons are used to ensure the safety

of people and machinery. The easySafety control relay simplifies the monitoring

and evaluation of safety-related signals by means of dedicated safety function blocks.

The latter offer comprehensive operating and diagnostic options.

The safety function blocks include, among others:

• Emergency stop

• Monitoring of movable guards

• Safe operation with two-hand control

• Monitoring of electro-sensitive protective equipment

• Standstill and maximum-speed monitoring

Integrating functional safety in machines

Functional safety is an essential part of the design process for machines because it is key

to protecting the wellbeing of the machine operator and keeping production up and running.

To ensure functional safety, the latest guidelines have to be applied – design guidelines with

standardized and accepted circuits can help to notably reduce implementation efforts.

The easySafety devices ensure the necessary levels of personal and

process safety, both in simple and in more complex systems.

The easySafety control relay from Eaton’s Moeller series combines both

safety and control functions in one device. The devices stand out for

their ease of use and their intuitive operation. The individual functions

can be combined with one another and provide rapid fault diagnostics

for machine and system components.

The easySafety control relay can be configured directly on the device

or via a computer by means of the easySoft-Safety software.

In addition to the safety circuit diagram, the devices also offer a circuit

diagram for standard tasks, such as the processing of diagnostic messages.

The available safety function blocks open up additional application possibilities.

AWS Cloud Application

The easyE4 control relay comes with a direct connection to Amazon Web Services (AWS),

one of the world‘s most widely used cloud platforms. This means that the information

stored on any number of easyE4 devices can be safely transferred to the cloud in compliance

with the latest cybersecurity standards. Once it is in the cloud, it can then be aggregated

to monitor processes, integrate features such as artificial intelligence or generate automated commands.

The connection takes place via MQTT, a lightweight messaging protocol. By securely transferring

data to the cloud, users can leverage AWS services such as data storage, analysis and visualization.

This enables the implementation of Internet of Things (IoT) solutions, from remote monitoring to machine

learning.

More flexibility with less components

The easyE4 base devices and input/output expansion modules are available with DC,

AC and UC (universal) voltage, which makes the devices ideal for use in machine

building or building applications. By means of up to 11 expansion modules, the base

devices can be expanded to max. 188 inputs/outputs. All the expansions can be mixed

and combined as required. Thanks to the clever plug-in technology, the expansion

modules can be quickly connected or replaced.

simple visualization options: whether on mobile devices thanks to the web

server including the integrated web-editor or with the easyE Remote Touch Displays.

The device can also be connected directly to Amazon Web Services (AWS).

The easyE4 series offers a wide range of communication options via the integrated

Ethernet interface featuring the functions of a mini-PLC for machine and system control.

With the integrated Modbus TCP client and server functionality, components of different

levels can be integrated. The communication modules for Modbus RTU and SmartWire-DT

make the easyE4 to a smart relay enabling the monitoring machines and systems.

Many other functions make the easyE4 a powerful micro controller that can also be

integrated into IoT system architectures.

Look to Eaton’s Cooper PowerE series 600 A 35 kV class DirectConnect

elbow arrester to offer wind farm customers significant cost savings and

ease of installation.

This new deadbreak design replaces three components:

bushing extender, loadbreak reducing tap plug and the traditional 200 A

elbow arrester. The DirectConnect elbow arrester is available in two design

options: VariGAP and M.O.V.E. Eaton values your trust in our experience to

engineer products that save you money.

Reliability, cost savings and ease of installation

Eaton is now combining their 40+ year track record in separable connectors

and 27 years in underground arresters to introduce the 600 A DirectConnect

elbow arrester.

Eaton offers a cost-effective design with a shorter stacking height.

With this design, you no longer have to worry about clutter or not being able to

fit your cable accessories into smaller enclosures. The DirectConnect elbow arrester

replaces three components with one and is over 50% smaller in size than the

traditional offering, cutting installation time by 80%.

Not only does this design save you money on direct material costs, but it also

reduces overall labor expenses.

The DirectConnect elbow arrester utilizes the design expertise and manufacturing

know-how that contractors, developers and owners alike have come to rely on from

Eaton. Specific for 35 kV wind farm applications, the VariGAP design option provides

enhanced temporary overvoltage (TOV) characteristics for superior MCOV performance

over time. The VariGAP design is available in 27 kV and the standard M.O.V.E. design

is available in 27 kV and 30 kV ratings. Installation is easy. Simply thread the adapter

into a standard 600 A bushing and install the DirectConnect elbow arrester onto the

bushing. The probe inside the arrester latches into the adapter.

How the ATC-900 evaluates closed or in-phase transitions

The controller software will confirm that the closed transition (CT) or

in-phase transition is enabled through the setpoints. When source

1 and source 2 are both available within voltage and frequency set

point tolerances:

• If S1 and S2 setpoints (UV/OV, UF/OF) are identical, there can be

a difference in voltage and/or frequency when transition occurs.

Also, if there is a difference in setpoints, the actual voltage and/or

frequency may be identical when the transition occurs.

• It confirms that sources are within closed or in-phase transitions

set point tolerances when:

• Voltage difference for closed transition = +/- 1 to 5%,

• There is no voltage difference setpoint for in-phase. As long

as both voltages are within voltage limits, any difference is

acceptable

• Freq. difference = +/- 0 to 0.3 Hz for closed transition

• Freq. difference = +/- 0 to 3 Hz for in-phase

• Phase angle, when the number of generators = 0. the phase

angle difference is fixed at +/- 8 degrees

• Phase angle, when the number of generators = 1 or 2. the

phase angle difference is fixed at +/- 5 degrees

• The controller attempts a closed or in-phase transition until the

sync timer (adjustable from 1 to 60 min) expires.
