Installation manual for the EXTER series operator panels
Foreword
The frame and casing are made of stainless steel grade 316/1.440l, affording out­standing toughness and excellent corrosion resistance for use throughout a whole range of corrosive environments and media.
All operator panels in the EXTER series 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 Information Designer configuration tool. The project can then be transferred and stored in the operator panel itself.
Various types of automation equipment such PLCs, servos or drives can be connected to the EXTER stainless operator panel. In this manual, the term “the controller” re­fers to the connected equipment.
This manual explains how to install the operator panel. Please refer to the reference manual for further information.

1. The operator panel’s mounting clamps do not provide a secure grounding con­nection between the panel and the device cabinet.
2. Connect a 2.5 mm
2
wire between the operator panel’s quick-connect plinth and
the panel chassis.
3. Connect a 6 or 4 mm
2
wire or grounding braid between the panel’s chassis and
the closest grounding point on the door.
4. Connect a strong but short grounding braid between the door and the device cabinet.
5. Twist the cables onto the 24 V DC feed.
6. A ferrite core suppresses disturbances to the 24 V feed. 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.
Remember:
The grounding wires should be short and the conductor should have a large area. A long, thin grounding wire has a very high impedance (resistance) at high frequencies and will not guide disturbances to the ground. Multi-wire conductors are better than single wire conductors with the same area. A braided conductor wire with the same area is even better. The best is a short, thick groundin g braid.

1. In some industrial units for Ethernet, the RJ45 contact’s shield is connected to the chassis via a capacitor.
2. The operator panel’s Ethernet shield is directly connected to the chassis.
Check whether the other Ethernet unit has its shield directly grounded or grounded via a capacitor.
In many cases, connecting the shielded Ethernet cabling to the chassis at both ends is inappropriate. Hum or grounding loops can occur. Unshielded cabling may even result in fewer communication errors.
A good solution may be to use a shielded Ethernet cable, but to connect the shield at one end only.
3. One option is to break the shield.
4. A more elegant method is to expand the shielded Ethernet cabling with a piece of unshielded Ethernet cable.
5. You can ground the shield via an external 0.1 uF/250 V plastic capacitor. This will connect the HF transients to the ground.

Additional Installation Tips

6.3 To Achieve Better EMC Protection

– Initially, use the original cabling from Beijer Electronics primarily. – Use shielded cables for RS232 communication. – Use twisted pair and shielded cabling for RS422 and RS485. – Use the 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 stan-
dard. – Use shielded cabling for Ethernet, preferably with foil + braided shield. – D-sub covers should be shielded, and the shield should be connected to the cover
360 ° where the cable comes in. – Connect the shield at both ends.
Shielded cable
0.1 uF/250 V
Ground plane 1 Ground plane 2
Not same potential
Ground plate
With longer distances, there is a risk that the ground potential may be different. In that case, the shield should only be connected at one end. A good alternative is to connect the other end of the shield to the ground via a 0.1 uF/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 avoiding the 50 Hz grounding loops.

EMC cable gland
Shielded cable Shielded cable
Plastic cable gland
– Use an EMC cable gland or regular plastic cable gland, remove the outer jacket
and connect the shield to the installation plate with a 360 ° metal cable clamp. – Place the 24 V DC and communications cabling in one cable trunk/cable duct and
230/380 V AC in another. If the cables need to be crossed, cross them at 90 ° only.
Avoid combining the cabling for stronger 24 V DC outputs with the communi-
cation cabling. – Ferrite cores that are snapped onto the shielded cabling may remove minor distur-
bances. 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 effi-
cient.

6.4 Ambient Temperature

The maximum ambient temperature for the operator panel is provided in the specifications. The ambient temperature refers to the temperature in the device cabinet which cools the panel’s electronics.

In most cases, the ambient temperature for the operator panel is significantly higher than the device cabinet’s ambient temperature.
If the cabinet is tall and there are a number of heat-generating devices, the temperature at the top of the cabinet will be considerably higher than the theoretical temperature increase that would be expected. All electronics are sensitive to heat. The lifespan of an electrolytic capacitor is cut in half with an 8-10 ° increase in temperature. A 15-20 ° temperature increase results in 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.
Install the fan so that it sits in the cooler area and will blow cold air against the operator panel. If the fan is mounted at the top and sucks air upwards, the fan’s ambient temperature will be higher = shorter lifespan.
A good fan with a ball-bearing mounting has an expected lifespan of at least 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 needs to come on when needed.
Large graphic terminals draw only one fifth of the current when the background lighting is off. The loss effect drops from e.g. 25 W to only 5 W.
The operator panel’s loss effect = supply voltage x current. Virtually no power goes to external users and no loss effects due to inputs.

Additional Installation Tips
1. If you use a power supply that meets safety standards and only feeds the operator
panel, there is no problem.
2. However, if you have a 24 V unit that also feeds other units, there is reason to be
cautious. 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 24 V feed is secure, for example, SELV according to EN 60950 (protection against electric shock) and UL 950.
Example:
Here is an example that explains why a secure 24 V DC feed can be ruined by mixing 24 V relay contacts with 230 V AC relay contacts in a smaller controller. Check that the “clearances and creepage distances between 24 V DC and 230 V AC fulfill EN 60950 or UL 950”. If not, input a separate 24 V unit into the operator panel.
3. If there is a substantial distance between the relay contacts for 24 V DC and
230 V AC, it is OK to use the same 24 V devices for all feeds.
4. Connect 0 V on the 24 V feed to the ground. This offers three advantages:
–Safety is increased. The 24 V feed will not be live in the event of a faulty connec-
tion or short circuit between 0 V (24 V) and 230 V phase. –Transients on the 24 V feed are connected to the ground. –No risk that the 24 V feed is at a high level in relationship to the ground. This is
not unusual since there is high static electricity.

When a PC is connected to the panel, the panel’s internal 0 V (GND) 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 are connected that have a 0 V and a ground connection, and these are connected to various grounding points, there is a substantial risk of problems. Grounding currents go through communication cables, the rear plate of the controller, and internally in the operator panel, and can cause errors.
Use external units to improve communication and achieve galvanic isolation. Westermo has good industry-standard insulators that are also insulated from the 24 V DC feed.
Note:
It is very important to make sure that the 24 V feed in the external insulation unit is not connected to one of the communication outlets. If it does not have 100% insulation against the 24 V feed, disturbances and grounding currents from the 0 V on the 24 V side will disrupt communication. Using this type of unit solves one problem but creates a larger problem! A substandard installation may work now, but problems may arise when other devices are connected.

Additional Installation Tips

6.7 Cable and Bus Termination RS485

– Use shielded and twisted pair cable.
The pair capacitance may not exceed 52.5 pF/m and area at least 0.25 mm
24), 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-way communication 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, the shield should be connected to the ground via 0.1 uF/250 V plastic capacitor to prevent ground current in the braided shield. A number of manufacturers recommend that the shield be grounded at each node.
Various manufacturers have different systems for bus termination. The RS485 standard does not describe how the “Fail Safe” function would be carried out, just that the system should be able to handle the error.
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).

1. Some (older) operator panels had pull-up and pull-down resistance except for the actual bus termination at 120 ohm, similar to Westermo and Profibus.
2. Newer panels have another type of recipient, so-called built-in “Fail Safe”, where simple bus termination resistance is sufficient.
If other nodes on the RS485 network require pull-up and pull-down and the operator panel is at one end of the loop, one of the following procedures can be carried out:
3. Connect two 1k/0.25 W resistors in the 25-pole D-sub contact. Set jumper pins 6-19.
4. Use CAB8. It offers the option of bus termination with pull-up/-down. It is also easy to connect the bus cable via the screw terminal block.
