1.Overview1.OverviewNoStatic Long Range System

The NoStatic Long Range system is a set of components used to neutralize electrostatic charges, without air assistance, over a relatively long range. In compari-son with conventional electro-static dischargers, based on low frequency transformer designs, which have an effective range of a couple of centimeters at most, the Long Range system has an effective range of approximately 1 meter.

In many of today’s manufac-turing processes, electro-static charges are an increasing problem due to high processing speed, low weight of the pro-cessed material and the use of compounds that are more sus-ceptible to static charge buildup. Many times it is not practical or even possible to remedy these problems with conven-tional electrostatic discharge equipment because of their low operating range and the limited space within the processing environment. In these cases our Long Range system is the ideal safe and simple solution. The long operating range allows it to be placed at some distance away from the problematic area where it doesn’t interfere with the actual manufacturing pro-cesses in the machine. The Long

Range system is also very well suited for applications where the distance between the discharger and the static buildup varies, for instance where large rolls are being wound or unwound.

The Long Range system is in-tended only for use in industrial environments!

A complete system consists in one central control unit (CCU) and up to four high voltage elec-trostatic discharger units (SER). The CCU central control unit is mains powered and provides distributed low power to each electrostatic discharger unit.

The only control on the front panel is a power switch which makes it very easy to oper-ate. No complicated settings to adjust – simply power it on and leave it alone. In addition, the CCU central control unit also has an input that can be used to remotely activate and deactivate the electrostatic discharging.

The SER electrostatic discharg-ers are supplied with low volt-age power from the CCU central control unit. The high voltage is produced entirely within the SER discharger units which means that the connecting cables can

be relatively long and of a com-mon type, making the installation easy. This is in contrast to many other high voltage electrostatic discharger equipments which require high voltage cables that can be of very limited lengths and is difficult to install.

The high voltage generated in the SER electrostatic discharger units is of such low power that it is totally shock proof accord-ing to prevalent safety standards and regulations. In addition, the high voltage emitters are shaped in a way that reduces the natural wear and breakdown caused by the high voltage. The shape also makes it easy to clean and sharpen the emitters on site. The electrostatic discharger unit’s design and technology is Patent Pending.

The rate at which the high volt-age alternates between positive and negative polarity in the SER electrostatic discharger units can be set to one of three fixed frequencies. The alternation frequency to use depends on the speed of the statically charged object. Higher speed requires higher frequencies but higher frequency also results in shorter operating range.

2.4. Electrical installation

All external connections are done through cable glands in the rear panel.

There is one cable gland for each electrostatic discharger unit, one for mains power, and one labeled Control for status relay outputs and remote control input. Remove the panel by unscrewing the 6 screws with a 2.5 mm hexagon key. The screws are held in place by the rubber gasket and completely loosened from the main frame when they are unscrewed 6-7 mm.

Make sure that the mains power is switched off before the panel is removed.

With the rear panel removed, all electrical connections are exposed on one circuit board. There are terminals for the electrostatic discharger units, mains and the remote control.

All terminal blocks are removable for easier access.

When all electrical connections are done, the rear panel has to be remounted before power is switched on. Also make sure that all unused cable glands have been properly sealed with the enclosed cable gland plugs.

2.4.1. Mains power

Mains power and protective ground is connected to CN7 and the earth bar.

The power inlet is protected with a single 500mA slow 5 * 20 mm

replaceable glass tube fuse, located on the bottom of the PCB close to the power inlet. The control unit can be connected to mains either with the supplied detachable power cord or with a fixed, nondetachable cord.

The CCU central control unit is a Class I type equipment which relies on the protective ground for electrical safety. In case of a detachable mains connection, make sure that the unit is con-nected to a grounded outlet. For both detachable and nondetach-able mains connections, make sure that the protective ground wire is firmly connected to the earth bar.

The control unit has to be provided with means to discon-nect it from all current carrying conductors to the mains power. If a detachable power cord is used this requirement is fulfilled with a mains socket outlet and the mains plug. For a non-de-tachable connection, an external circuit breaker in close proximity to the control unit within easy reach of the operator has to be used. The circuit breaker has to meat the relevant requirements of IEC 60947-1 and IEC 60947-3 and should be marked as the disconnecting device for the equipment.

The mains supply cord shall be rated for 230VAC, have an area of at least 0.75mm² and meet the requirements of IEC 60227 or IEC 60245.

2.4.2. Connections to the electrostatic discharger units

The electrostatic discharger units are connected to CN5 and CN6.

Electrostatic discharger unit no. 1 is connected to terminals 1, 2, 3 and 4 in CN5. Unit no. 2 is con-nected to terminals 5, 6, 7 and 8 in CN5. Unit no. 3 is connected to terminals 11, 12, 13 and 14 in CN6. And unit no. 4 to terminals 15, 16, 17 and 18 in CN6.

Each separate wire in the SKHE/LR cable is marked with num-bers 1 to 4. These correspond directly to the order in which they are to be connected in the control unit and the numbering of the poles in the plug/socket connection in the discharger unit.

The plug connected to the dis-charger unit is manufactured by Hirschman and has type name G4W1F. The connecting wires should have an area of at least 0.5 mm².

The remote control signal is an input which is activated with a DC voltage above approximately 4V. Maximum input voltage is 30V. The input is sensed with an optic coupler which makes it galvanically separated from the rest of the circuits in the control unit. The input is current limited with a 4700Ω resistor which means that it requires a current of approximately 0.6 to 6mA between 5 to 30 volts.

The remote control input can be set to either start the electro-static discharger units or stop them when the input is activated. See 2.6. Operating Parameters below. When the electrostatic discharger units are deactivated by the remote control input (either by activating or deacti-vating the input, depending on settings of the operating param-eters), the power indicator on the front panel changes from steady green to alternating between red and green.

2.5. High voltage polarity alternation frequency

The frequency at which the high voltage alternates between posi-tive and negative polarity deter-mines the maximum speed of the object to be electro statically discharged. The faster an object

is passing the operating field of the electrostatic discharger unit, the faster the high voltage must alternate between positive and negative polarity in order to efficiently neutralize all the static

charges on its surface. Higher polarity alternation frequency also results in shorter operat-ing range which means that the alternation frequency shouldn’t be set higher than necessary.

There are many factors besides the speed itself that determine the optimal polarity alternation frequency for an application, for example the distance be-tween the discharger unit and the object to be neutralized, the length of the discharger unit, the placement of the discharger unit in the machine, to name but a few. This makes it hard to set

up general rules for all possible applications.

However, it has turned out that in the majority of all installa-tions, an alternation frequency of 5Hz has given the best result. It is only in rare cases that the alternation frequency has to be changed.

The jumper blocks are positioned below the corresponding terminals for each electrostatic discharger unit. In order to change the position of the jumpers, the terminal blocks have to be unplugged.

Jumperfor unit 1

Jumperfor unit 2

Jumperfor unit 3

Jumperfor unit 4

In the central control unit, there is one jumper block used to set the polarity alternation frequency for each electrostatic discharger unit. The polarity alternation can individually be set to a frequency of 1.4Hz, 5Hz, or 10Hz. As default, the jumpers are set for a frequency of 5Hz.

Jumper position Alternationfrequency

Use

5Hz The default setting. This usually gives a good result for both speed and range. 5Hz also becomes the setting if the jumper is removed.

10Hz For use with high speed. When the object to be neutralized is moving very fast the polarity alternation frequency may have to be increased in order to efficiently neutralize the static charges. The higher alternation frequency also reduces the efficient operating range of the electrostatic discharger unit.

1.4Hz For use with extremely long range and slow speed. When the object to be neutralized is far away from the electrostatic dis-charger and it is moving slow or is stationary, the polarity alterna-tion frequency can be decreased in order to increase the effective operating range.

Note that some types of elec-trostatic discharger units can be more sophistically controlled directly by the central control unit. For these types of discharg-er units, the polarity alternation can be set to more than three frequencies, the ratio between positive and negative polarity can be varied and the output power can be changed. When using this kind of discharger, the jumper has to be set in the position for 5Hz or be completely removed. See also the individual documentation for the specific electrostatic discharger unit.

In some cases, changing the frequency is not enough; instead two or more electrostatic dis-charger units evenly positioned over a larger area has to be used. This way, both high speed and extremely long operating range can be achieved.

2.6. Operating parameters

Behind the front panel there are a set of switches which are used to change some of the operating param-eters in the central control unit.

Make sure to disconnect the mains power before removing the front panel.

The front panel is removed by unscrewing the 6 screws with a 2.5 mm hexagon key. The screws are held in place by the rubber gasket and completely loosened from the main frame when they are unscrewed 6-7 mm.

Note that the protective ground cable on the inside of the front panel may not be removed.

The only operating parameter that can be changed in the CCU/LR01 variant is for the remote control input.

The switch has four levers which can be either on or off. When the lever is in the top position, the switch is set to off.

Switch Position Function

1 Top - off When the remote control signal is active (high, >4V) the electrostatic dis-chargers are deactivated (switched off).

1 Down - on When the remote control signal is active (high, >4V) the electrostatic dis-chargers are activated (switched on).

All switches set to the off position are the default factory setting.

2.7. Front panel control and indicator

The front panel has a control and indicator for power and status relay output override.

2.7.1. Power

The power switch is used to switch the mains power to the central control unit on and off. When power is switched on the power indicator immediately flashes green and then switches to a steady green state after a short period.

When the remote control signal has deactivated the electrostatic discharger units, the indicator al-ternates between red and green light, with the ontime for the red much longer than for the green.

3.Electrostatic Discharger UnitEDU/LR01

3.Electrostatic Discharger UnitEDU/LR013.1. General Description

The electrostatic discharger unit is supplied with a low power voltage from the central control unit. This low voltage is internally converted to high voltages used to neutralize the electrostatic charges. It has no operating con-trols or indicators and the only connections are to the central control unit and a functional earth connection.

Although the discharger unit generates a high voltage of both positive and negative polarity,

the maximum output current is low enough to make it to-tally shock proof according to prevalent safety standards and regulations.

The discharger unit contains supervisory circuits that continu-ously monitor the output voltage. If, for any reason, the output voltage isn’t present, the central control unit can notify external circuits via relay outputs or other types of industrial communica-tion.

Liros manufactures several types of electrostatic discharger units. The one described here is the EDU/LR01 which is the most commonly used. Consult the individual installation manu-als regarding specific data and installation instructions for the other types of electrostatic dis-charger units.

The Long Range system is in-tended only for use in industrial environments!

The marking on the electrostatic discharger unit shows the CE

mark, the GS mark, the product model number and name, the name and contact information of the manufacturer, the manu-facturing year and serial number and some of the rated data.

The marking shows that the electrostatic discharger unit is to be powered with 24VDC, has a current consumption of max 130mA, is sealed to an ingress protection of IP54 and can operate in an environment

with temperatures between 0°C to 50°C. It also shows that the output voltage is max ±13kV DC with a maximum output current of 1.7mA.

The same standards and direc-tives, regarding the CE and GS mark, as for the CCU central control unit applies for the SER electrostatic discharger unit, see 2.2.

Liros supplies mounting bracket for mounting the SER/LR01 discharger unit in a process-ing environment. The brackets are mounted on a machine or a fixture and the discharger unit is snapped onto the bracket. It is recommended to use approxi-mately one bracket per meter and never less than two.

SEH/LRB-3

The brackets are made of PE-1k and the discharger units of PVC. Never put screws directly into the discharger unit and don’t use any other type of brackets than those supplied by Liros.

The ambient temperature in the area where the discharger unit is to be mounted must not exceed 50°C.

Even though the electrostatic discharger unit it is totally shock proof, it can still be very unpleasant to directly come in contact with the high voltage emitters. This could in turn lead to secondary injuries, e.g. when somebody by reflex quickly withdraws an arm. Therefore it is recommended that the discharg-er is mounted in such a way that its high voltage emitters are protected from direct contact with the machine operators.

Also make sure to not mount the discharger unit in a location or position where objects, both metal and of other materials, can fall into the space in the discharger unit where the high voltage emitters are located.

The shortest distance between the high voltage emitters and any surrounding objects where the discharger is mounted must be at least 50 mm.

The SER/LR01 is a long range discharger that works most effectively at a distance of 150 mm or more between the object to be neutralized and the dis-charger unit. For shorter distanc-es, either one of Liros’ standard short range discharger units or a Long Range discharger unit specifically designed for shorter minimum distance should be used.

3.3.2. Placement in a machine or process

The process of electrostatic discharging with high voltage can increase the ozone concen-tration level in the surrounding environment. Long term and repeated exposure to elevated

levels of ozone concentration in the air is harmful to the human body. The ozone concentration a worker will be exposed to around a machine or process is partly dependent on how many

discharger units are used, how close together they are, how long they are continuously running, how far they are located from the worker, and partly by the size of the premises where the

machine or process is located, and how quick the air is replaced by ventilation.

In most countries, laws and regulations dictate the maxi-mum limits for various toxic substances, including ozone, to which a worker can be exposed. It is the responsibility of the employer to keep the working environment within the given limits for the toxic substances. The ozone concentration can be

reduced by changing the contrib-uting factors. Using the remote control function to only have the discharger unit on when it is needed is one way to do this. Another way is to increase the ventilated air volume.

Make sure that the ozone con-centration in the working envi-ronment is kept below permissi-ble limits according to local laws and regulations.

The connection between the central control unit and the elec-trostatic discharger unit is done with the SKHE/LR signal cable. It is simply plugged into the mating socket on the discharger unit and secured with the fastening screw.

Always make sure to switch the central control cnit off before an electrostatic discharger unit is connected or disconnected and never operate the discharger unit without a local earth connec-tion – See also paragraph 3.4.2. below.

The high voltage is generated entirely inside the discharger

unit and the connection cable only supplies voltages below 30VDC. This means that there are no special restrictions for how the cable is mounted or fixed in the application. This is a huge advantage compared to many other high voltage dis-chargers, which generate the high voltage in a central unit and run this in special high voltage cables to the discharger ele-ments.

See also paragraph 2.4.2. above for more information about the signal cable.

Not only does this mean bad electrostatic neutralization per-formance, but it can also create high EMF that disturbs sensitive electronic equipment. It can also damage the central control unit and the discharger units, be-cause current may instead flow from the mains earth connection, capacitively coupled through the control unit and the discharge unit.

The connection to a local earth point is done with a ring crimp terminal fitted with an M5 screw (hole diameter = 5.1 mm).

Make sure to assemble the nut, washers and ring crimp terminal as shown in order to ensure a good and reliable connection. Also make sure to not loosen the innermost nut. Use a cable with an area of at least 2.5 mm².

The local earth should preferably be connected to the grounded metal body of the machine on which the electrostatic discharg-er is used and as close to it as possible.

3.4.2. Local earth connection

Never operate the Long Range system without a local earth point connected to each elec-trostatic discharger unit.

The high voltage in the electro-static discharger units needs a current path to a local earth point in order to function cor-rectly and with high performance The electrostatice discharger unit has a facility for an earth connection in the same end as the socket for the signal cable. In order to get a good electrostatic neutralization effect it is of high importance that this cable is connected correctly. It should be as short as possible, preferably less than 2 meters, and it has to be firmly connected in both ends. This is a functional earth connection, not a protective earth connection, which should not use cables with the same colour and marking as a cables used for the protective earth.

The electrostatic discharger unit contains circuits that continu-ously monitor the high voltage outputs. In case there are any faults that cause one or both polarity of the high voltage to disappear – e.g. emitters are short circuited by foreign objects – this is communicated to the central control unit, which in turn

can notify a supervisory machine controller via relay outputs or other types of communication.

The electrostatic discharger unit actually sends an OK signal periodically to the central control unit instead of an error signal. This means that if the elec-trostatic discharger unit stops

working in any way, even by a disconnected or short circuited connection cable, the central control unit will know.

The shape of the high voltage emitters in the Liros Long Range discharger units is different from those of most conven-tional electrostatic neutralizers. The conventional method is to use needle shaped emitters. The sharper an emitter is, the easier it is for the electrons to move between the emitter and the molecules to be ionized in the air. However, the electron migration also deteriorates the tip of the needle, making it less sharp over time. Instead, the Liros Long Range discharger units are equiped with circular, tube-like emitter, with sharpened ends. This way, a much larger surface than a single needle point is used, which reduces the deteriorate. The emitters are also easily sharpened with a standard countersinker tool.

4.Operation andmaintenance

4.Operation andmaintenance4.1. Operation

Before power is applied for the first time make sure to check:

The central control unit is properly fastened in its mounting location.

The central control cnit is properly earthed.

All wiring is done in accordance with this installation guide and that all local legislative requirements regarding electrical installation are met.

All unused cable glands in the central control unit are sealed with the enclosed cable gland plugs.

The electrostatic discharger units are properly mounted and fixed with Liros’ manufactured and sup-plied mounting brackets.

The electrostatic discharger units are connected to a local earth point.

The space for the high voltage emitters in the discharger units is free from any foreign objects.

The high voltage emitters are located at least 50 mm away from the nearest surrounding objects.

Once the central control unit and electrostatic discharger units are mounted and set according to the instructions in this installation guide, there are no other adjustments or settings to be made during normal operation. Just power it on and let it run.

There are no restrictions on the operating time; the NoStatic Long Range system is designed to operate continuously under normal conditions.

The NoStatic Long Range system contains no parts that wear out or have to be replaced under normal operation.

If the simple maintenance procedures described below are performed, it will guarantee a long and trouble-free use of the

4.2. Maintenance

system.

Always make sure to switch the power off with the mains power switch before cleaning the system.

Use a soft cotton cloth, lightly moistened with a mild solution of detergent and water to clean the surface of the central control unit and discharger units. Any strong solvents, such as thinner and acetone must not be used because it can dissolve the PVC and rubber materials used in the system. PVC is mainly used for

the discharger unit, but also in the power switch and front panel of the central control unit. Rub-ber is used in various gaskets to keep the ingress protection at IP54. Strong solvents can also dissolve the print on the central unit. Make sure to dry the dis-charger units thoroughly before power is applied again.

It is especially important to keep the space in the discharger unit, where the high voltage emitters are located, clean. Any foreign

4.2.1. Cleaning

material or substance within this space can seriously degrade the performance of the unit. Even though the discharger unit can temporarily operate short circuited or while arching, this condition may permanently de-teriorate the high voltage output if sustained for a long period of time. Note that even materials that are not normally conductive can contribute to creeping of the high voltage between the emit-ters, due to its surface properties regarding high voltages.

In order to keep the electro-static neutralization effect at an optimum level, the high voltage emitters may need to be sharp-ened. A standard 90° counter-

sinker tool with a diameter of at least 10 mm may be used. Make sure to switch the power off with the mains power switch before sharpening the emitters.

4.2.2. High voltage emitters

Remove all residue metal chips from the electrostatic discharger unit when done with thesharpening.

Periodically check that the earth connections in all electrostatic discharger units are properly connected to a local earth point.

A bad connection may lead to degraded performance of the discharger units.

Neither the central control unit nor the electrostatic discharger unit is field repairable and contains no replaceable parts,

except for the mains fuse. Any attempt to modify or repair these units will void the warranty and the conformity regarding safety

4.2.4. Repair

and EMC. If repair is necessary, return the units to the manufac-turer.

Make sure that the ozone con-centration in the working envi-ronment is kept below permissi-

ble limits according to local laws and regulations.

4.2.5. Ozone concentration

Before contacting Liros or any of its partners for support, consult the following symptoms and cause table for trouble shooting.

4.3. Troubleshooting

ID Symptom Cause Solution

1 Power indicator does not light up when switched on, and no neutralization effect from the discharging unit.

Mains fuse broken. Replace fuse. See 2.4.1.

2 No neutralization effect, and the power indicator on the CCU alternates between red and green light, with the red on much longer than the green.

The electrostatic discharger units are switched off with the remote control input.

Set the remote control signal to active state – see 2.4.3. Or change the polarity for the remote control input – see 2.6.

3A Poor neutralization effect. Earth connection in the dis-charger unit is bad or not con-nected to local earth.

Make sure the earth connec-tion is properly connected to a locally earthed object. See 3.4.2

3B Poor neutralization effect. Dull high voltage emitters. Sharpen high voltage emitters. See 4.4.2.

3C Poor neutralization effect. Foreign objects in the dis-charger unit, or layers of dirt or process residues cover the high voltage emitters.

Clean the electrostatic dis-charger unit. See 4.2.1.

ID Symptom Cause Solution

4 Poor or no electrostatic neutral-ization effect for one or more electrostatic discharger units.

Fault in wiring between the central control unit and the electrostatic discharger units.

Check the wiring between the central unit and the discharger units. Verify that the wiring is done according to 2.4.2. and that the plugs are firmly con-nected in the discharger units.

5 Electrostatic neutralization effect is low when machine is running at full speed.

The high voltage polarity alter-nation frequency is set too low for the speed of the charged objects in the application.

Increase the high voltage polarity alternation frequency – See 2.5.

6 Unexpectedly short operat-ing range of the electrostatic discharger unit.

The high voltage polarity alternation frequency is set too high for the application.

Decrease the high voltage polarity alternation frequency – See 2.5.

In case there is any uncertainty about the function of the dis-charger unit and the neutraliza-tion effect, the output voltage

can be measured to give a rough indication of weather the Long Range system is operating as in-tended or not. This can be done

4.4. Checking the high voltage output level

1. Switch the static detector off (release the button).

2. Make sure the Long Range system is switched on.

3. Move the static detector at least 1 meter away from any active electrostatic discharger unit, including the one to be checked.

4. Switch the static detector on (push the button).

5. Move the static detector to a position about 200 mm away from the electrostatic discharger unit to be checked. Position it at an equal distance to two of the high voltage emitters.

6. Verify that the static detector is indicating full swing between positive and negative polarity at the same rate as the operating frequency of the high voltage polarity alternation.

in several ways, some of which are described below.

1. Switch off the Long Range system.

2. Connect a wire to the earth connection of the electrostatic discharger unit to be checked. Do not discon-nect the local earth wire used for normal operation.

3. Switch on the Long Range system.

4. Approach the other end of the wire to one of the high voltage emitters.

5. Verify that there is a bright white or light blue spark between the emitter and the wire when the distance between them is approximately 20 mm. The spark should pulse with the same frequency as the high voltage polarity alternation frequency.

6. Move the wire to an adjacent high voltage emitter and verify that it is sparking with the same intensity and frequency at the same distance between the wire and the emitter as for the other emitter.

Note that this test method generates high radiated EMF that can disturb nearby electronic equipment. It can even disturb the electrostatic discharger unit that is being checked. The disturbance can be noticed as a change of the operating polarity alternation frequency. Do not run this test for longer than necessary since the arching can deteriorate the high voltage outputs if sustained for a long period of time.

4.4.2. Using an earthed wire

1. Switch off the Long Range system.

2. Connect the negative measuring clip and the earth connection of a 1000:1 high voltage probe to the local earth connection of the electrostatic discharger unit to be checked.

3. Connect the positive measuring clip of the high voltage probe to one of the high voltage emitters.

4. Connect the output of the high voltage probe either to a voltmeter or an oscilloscope. The voltmeter should have max and min detection of the input signal to reliably show the voltage at the higher polarity alternation frequencies.

5. Set the voltmeter or the oscilloscope to measure a voltage of -5 to +5V.

6. Switch on the Long Range system.

7. Verify that the voltmeter or the oscilloscope is showing a voltage swing either between less than -2V and 0V for the negative high voltage emitters or more than +2V and 0V for the positive emitters and that the period of the signal corresponds to the set high voltage polarity alternation frequency.

The high voltage probe must have a maximum working voltage of at least 40kVDC and an input impedance of 1000MΩ or more to give accurate readings.
