Installation manual for E1101

Foreword

All E1000 are developed to satisfy the demands of human-machine
communication. Built-in functions such as displaying and controlling text,
dynamic indication, time channels, alarm and recipe handling are included.

The operator panel works primarily in an object-oriented way,making it easy to
understand and use. Configuration is carried out on a PC using the configuration
tool. The project can then be transferredand stored in the operator panel itself.

Various types of automation equipment such PLCs, servos or drives can be
connected to the E1000. In this manual, the term “the controller” refers to the
connected equipment.

This manual explains how to install the operatorpanel. Please refer to the
reference manual for further information.

The operator panel’s mounting clamps do not provide a secure grounding

1.

Connect a wire that is sized correctl

y according to local electrical codes

between the operator panel’squick

-connect plinth and the panel’s chassis, see

2indrawingabove.

2.

Connect a 6 or 4 mm

wire or grounding braid between the panel’s chassis and

the closest grounding point on the door, see 3 in drawing above.

3.

Connect a strong but short grounding braid between the door and the device
cabinet,see 4 in drawing above.

4.

Twist the cables onto the 24 V DC feed, see 5 in drawing above.
2 turns around the ferrite core provide 4 times the suppression of 1 turn.
3 turns around the ferrite core provide 9 times the suppression of 1 turn.

A ferrite core suppresses disturbancesto the24 V feed, see 6 in drawingabove.

Note:

The grounding wires should beshort and the conductor shouldhave a large area.
A long, thin grounding wirehas a very high impedance(resistance)athigh frequencies
and will not guide d isturbances tothe ground.
Multi-wireconductors are better thansinglewireconductorswiththesamearea.
A braided conductor wire with the samearea is even better. The best is a short,thick
grounding braid.

In some industrial units for Ethernet, the RJ45 contact’s shield is connected to the
chassis via a capacitor, see 1 in drawing above.

The operator panel’s Ethernet shield is directly

connected to the chassis, see 2 in

drawing above.

1.

Check whether the other Ethernet unithas its shield directly grounded or
grounded via a capacitor.

Note:

In many cases, connecting the shieldedEthernet cabling to the chassisatboth ends is
inappropriate. Hum or grounding loops can o ccur. Unshielded cabling may even result
in fewer communication errors.

A good solution maybe to use a shielded Ethernet cable, but to connect the shield
at one end only.

One option is to break the shield, see 3 in drawing above.
A more elegant method is toexpand the shielded Ethernet cabling with a piece of

unshielded Ethernet cable, see 4 in drawing above.
You can ground the shield via an external 0.1 μ F/250 V plastic capacitor,see 5 in

drawing above. This will connect the HF transients to the ground.

Mitsubishi Electric, MA00779E

Additional Installation Tips

6.3 To Achieve Better EMC Protection

• Useshielded cables for RS232 communication.

• Usetwisted pair and shieldedcabling for RS422 and RS485.

• Usethe cabling intended for the bus type; Ethernet, Profibus,CC-Link,

CAN, Device Net etc.

• Install and connect according to applicable specifications for the relevant bus

standard.

• Useshielded cabling for Ethernet,preferably with foil and a braided shield.

• D-sub covers should be shielded, and the shield should be connected to the

cover 360° where the cable enters.

• Connect the shield at both ends.

With longer distances, there is a risk that the ground potentialmay be different.
In that case, the shield should only be connected at one end. A good alternative is
to connect the otherend of the shield to the ground via a 0.1 μ F/250 V plastic
capacitor. Both ends are then connected to the ground in terms of HF, but only
connected to the ground at one end in terms of LF, thus avoidingthe 50 Hz
grounding loops.

2.

Place the 24 V DC andcommunications cabling in one cable trunk/cable duct
and 230/380 V AC in another. Ifthe cables need to be crossed, cross them at
90 ° only. Avoidcombining the cabling for stronger 24 V DC outputs with
the communication cabling.

Ferritecores that are snapped onto the shielded cabling may remove minor
disturbances. Large ferrite pieces that are snapped onto unshielded cabling and
where the wires go 2-4 times around the cores are approximately 5-25 times more
efficient.

Inmostcases,theambienttemperaturefortheoperatorpanelissignificantly
higher than the device cabinet’sambient temperature.

If the cabinet is tall and there are a number of hea

t-generating devices, the

temperature at the top of the cabinet will be con

siderably higher than the

theoretical temperature increase that would

be expected. All electronics are

sensitivetoheat. Thelifespanofanelectro

lytic capacitor is cut in half with an

8-10 °C increase in temperature. A 15-20 °C t

emperature increase resultsin a

quarter of the lifespan etc.
Rittal has a good program for estimating the anticipated average temperature in

the cabinet as well as a large program for controlling the temperature in the device
cabinet.

An enamel-coated steel cabinet has

a radiant heat value of 5.5 W/m

2

and degrees

C.
Installing a fan inside the cabinet will even out the temperature, while moving air

provides considerably better cooling than still air. A suitable fan is a 120 x 120 mm
axial fan, available in 24 V DC, 115 and 230 V AC.

Installthefansothatitsit

s in the cooler area and blows coldair against the operator

panel. If the fan is mounted

at the top and sucks warm air upwards, the fan’s

ambient temperature will

be higher, resulting in a shorter lifespan.

Agoodfanwithaball-bearingmountinghasanexpectedlifespanofatleast
40,000 hours (not a guaranteed lifespan) at 40 °C. This corresponds to at least 4
years of continuous use. If a thermostat is installed, the fan only operates when
needed.

Large graphic termi

nals draw only one fifth of the current when the background

lighting is off. Th

e loss effect drops from e.g. 25W to only 5 W.

An approximate value of the net power consumption for the operator panel can
be calculated by multiplyingthe supply voltage with the current drawn by the
operator panel. This is assuming that all supplied power is transformed to heat.

If a power supply that meets safety standards is used and only feeds the operator
panel, there is no problem. See1 in drawing above.

However, if a 24 V unit that also feeds other units is used, there is reason to be
cautious, see 2 indrawing above. The operator panel does not have insulation
that meets safety requirements in the event of a potential short circuit between
230 V AC and 24 V DC. It is assumed that the 24V feed is secure, for example,
SELV according to EN 60950 (protection against electric shock)and UL 950.

Note:

Here is an example thatexplains why a secure 24V DC feed can beruined by mixing
24 V relay contacts with 230 VAC relay contacts in a smaller controller. Check thatthe
clearancesand creepage distances between 24 V DCand 230 V AC fulfillEN 60950 or
UL 950. Ifnot,input a separate 24V unit into the operator panel.

If there is a substant

ial distance between the relay contacts for 24 V DC and

230 V AC, it is OK to us

e the same 24 V devices for all feeds. See 3 in drawing

above.
Connect 0 V on the 24 V feed to the ground, see 4 in drawing above. This offers

three advantages:

• Safety is incre

ased. The 24 V feed will not be live in the event of a faulty

connection or

short circuit between 0 V (24 V) and 230 V phase.

• Tr a n s ie n t s on

the 24 V feed are connected to the ground.

• No risk that t

he 24 V feedis at a high level in relationship to the ground. This

is not unus

ual since there is high staticelectricity.

When a PC is connected to the panel, the panel’s internal 0 V (G

ND) will be

connected to the protective ground via the PC.
A number of USB devices can have the shield connected together with the

protective ground. Here, the panel’s 0 V (GND) is connected to the protective
ground when, for example, a USB memory stick, keyboard or similar device is
plugged in.

If a number of units areconnected that have a 0 V a

nd a ground connection, and

these are connected to various grounding poin

ts, there is a substantial risk of

problems. Groundingcurrents go through com

munication cables, the rear plate

of the controller,and internally in th

e operator panel, and can cause errors.

Use external units to improve communication and achieve galvanic isolation.
Westermo has good industry-standardinsulators that are also insulated from the
24 V DC feed.

Note:

It is very important tomake sure that the 24 V feed in theexternal insulation unit is not
connected to one of the communication outlets. If it does not have100% insulation
againstthe 24 V feed,disturbancesand grounding currents from the 0V on the 24 V
side will disrupt communication.
Using this type of unitsolvesone problem but creates a larger problem! A substandard
installationmaywork now, but problems may arise when otherdevicesareconnected.

6.7 Cable and Bus Termination RS485

• Use shielded and twisted pair cable. The pair capacitancemay not exceed 52.5

pF/m and area at least 0.25 mm

2

(AWG24), if you want to use the maximum

transfer distance and maximum transfer speed.

• 0 V, the reference voltage for communication should be included in

the cabling. With two-waycommunication use two pairs; one pair for
communication and one pair for 0 V.

• The shield must be grounded at one end. The other end is usually grounded,

but with longer distances or when there is a difference in the ground potential,
theshieldshouldbeconnectedtothegroundvia0.1μF/250Vplastic
capacitor to preventground current in the braided shield. A number of
manufacturers recommend that the shield be grounded at eachnode. Various
manufacturers have different systems for bus termination. The RS485
standard does not describe how the “FailSafe”function would be carried out,
justthatthesystemshouldbeabletohandletheerror.

Depending on the recipients’ design, the bus wires may be on the same level or
require pull-up or pull-down to ensure that no faulty signals are detected when the
bus is in resting mode (all transmitters are disconnected).

Some (older) operator panels had pull-up and pull-down resistance except for
the actual bus terminationat 120 Ω, similar to Westermo and Profibus. See1 in
drawing above.

Newer panels have another type of recipient, so-called built-in “FailSafe”,where
simple bus termination resistance is sufficient. See2 in drawing above.

If other nodes on the RS485network require pull-up and pull-down and the
operator panel is at one end of the loop, oneof the following procedures can be
carried out:

• Connect two 1 kΩ / 0.25 W resistors in the 25-pole D-sub contact. See 3 in

drawing above. Set jumper pins 6-19.

• UseCAB8. It offers the option of bus termination with pull-up/-down. It
