Introduction
The Meech 910 Bar is a powerful static eliminator which is completely shockless
in operation and which will give many years of excellent service, provided that the
following instructions are observed closely.
General Notes On Operation
The typical Meech 910 installation consists of one or more bars connected to a Meech
Power Unit.
The Power Unit converts the primary electricity supply into a high voltage, low
amperage output. This output energy is transferred to the Meech bar by the HT cable.
A capacitive coupling inside the bar reduces the energy at the ionising pin to a level
which is completely shockproof to a human being.
The stainless steel pins on the bar emit the energy to form an ionised air corona.
When a statically charged object passes through this corona the free moving ions
are attracted to the opposite charge on the object. In this way the static electricity is
neutralised. Unused ions in the corona recombine or are discharged to earth.

Installation of RML Bars
Correct positioning of the bar(s) is vital to ecient operation. The general rule is that
they should be positioned immediately before the problem area, remembering that
subsequent passage of the material over rollers, or friction, can regenerate the static
charge.
The following rules should be observed closely:
1. The optimal distance from material to be neutralised.
5
2. Free space is needed on opposite side of material, not a roller or solid object.
3. Avoid proximity to earthed parts of machine as this will distort the corona and
reduce its eciency.
6
4. If bars are needed on each side of the material, they should be staggered.
5. If more than one bar is needed on the same side, they should be spaced apart.
6. Two steel xing strips are supplied with each bar for ease of installation.
The bars must be earthed for correct operation. If in any doubt run an earth
wire from the bar to the earth stud on Power Unit.
Maximum operating temperature 85 degrees C.

Maintenance
Ionisers require periodic cleaning. During normal operation, dirt will build-up on
the emitter pins and upon the body of the ioniser. This will cause a reduction in
performance.
Typically, weekly cleaning is sucient. However, equipment used in some heavy
contamination areas, such as gravure printing or where plastic fumes are present, may
require daily cleaning. Equally, in a Class 100 area, cleaning may only be required on
a monthly basis.
Before cleaning, ensure that the equipment is switched o.
Emitter pins can be cleaned very eectively with a brush. A dry toothbrush is ideal.
Ionising bars will need periodic wiping to clean grey deposits from the surface
of the bar. A cloth moistened with a small amount of IPA or methylated spirits is
recommended.
Should you have any additional questions regarding the maintenance of Meech
equipment please contact Meech International directly or your local Meech distributor.

Fault Finding
Tests must be completed by a qualied electrical engineer.
If in doubt contact Meech head oce or your local distributor.
CAUTION: Whilst no danger to personnel exists, it is essential than any high
voltage ionising equipment, (exception Meech Model 910 Water Resistant
Ionising Bars), make no contact with water or water based uids. Should
such an event occur, disconnect immediately and return equipment to the
manufacturer for water damage assessment. High voltage electrical equipment
should not make contact with water.
The model 910 ionising bar forms part of a system, comprising of itself and a Model
904 power supply. (See g 1)
To verify where a fault may have occurred it is important to test each item of the
system individually. Should more than one ionising appliance be connected to one
power supply, these must be tested individually.
To check the model 910 ionising bar follow the procedure detailed below.
1. Switch o the electrical supply to the system.
2. Disconnect all ionising appliances from the power supply.
3. Follow the test procedure for the model 904 power supply. This can be found
in the instruction manual of the model 904.
4. Having checked the power supply reconnect one ionising model 910 ionising
bar.
5. Using a high voltage probe (RS 610 281) and meter (RS 610 590) measure
the voltage on the pins of the ionising bar. This voltage should be
approximately 2.7 kV.
6. If the voltage is below 2.0 kV then the item should be returned to Meech for
service and or repair.
7. If no meter and probe is available, then a fast and simple test is to simply
short the pin of the ionising bar to earth using a screwdriver as follows.
Place the shaft of the screwdriver against the aluminium extrusion of the ionising
bar.
Approach the pin of the bar with the point of the screwdriver. As the screwdriver
approaches the pin, a small faint spark should jump from the pin to the
screwdriver. If The bar is under direct sunlight or bright lights it may be dicult to
see this spark.
As the spark is drawn a slight buzzing sound will also be heard. This would
indicate the bar is functioning correctly.
8. If there is more than one appliance to test, disconnect the rst item and
repeat the above steps.
Repairs and Warranty
The Meech 910 Bar is warranted by Meech Static Eliminators Ltd to the original
purchaser against defects in material and workmanship for one year after purchase.
Should any malfunction occur, please return the Ioniser directly to us. All products
returned to the factory MUST be accompanied by a return authorisation number and
must be shipped prepaid. For prompt service, ship the unit to the factory with the return
authorisation number shown clearly on the label. Be sure it is well packed in a sturdy
carton with shock absorbing material.
Include a note stating the nature of the problem as specically as possible, and also
include instructions for returning the Ioniser to you. We will pay one-way return surface
shipping costs on any repairs covered under the warranty.
Field repairs should not be undertaken during the warranty period. Repair attempts by
unqualied personnel will invalidate the warranty.
