  • Page 5: Introduction

    Introduction The Meech Model 915 has been designed for use on the most arduous static elimination problems. The special resistive coupling of its emitter pins renders them shockless, whilst giving powerful static neutralisation performance. This enables the bar to eliminate very high static charges on high speed webs and at longer ranges than...

  • Page 6: Inspection

    Inspection The Model 915 Bar was carefully packed at the factory. Nevertheless, we recommend careful examination of the carton and contents for any damage. If damage is evident, keep the packing material and immediately notify the carrier of a possible damage...

  • Page 7: Operation

    Operation The typical Meech Model 915 installation consists of one or more bars connected to a Meech Model 904 Power Unit. The Power Unit converts the electrical supply into a high voltage, low amperage output. This output energy is transferred to the 915 bar by the HT cable.

  • Page 8: Installation

    Installation The 915 Bar can be placed between 25mm and 150 mm from the surface to be neutralised. It is important to ensure that the target surface has free air on both sides and that earthed metal objects are, where possible, at least 20 mm away from the bar.
  • Page 9 However, it is good practice to provide a secondary grounding through the fixing points where practical. The HT cable and armoured conduit require connection to a Meech model 904 power unit. Please consult the 904 instruction manual for further instruction.
  • Page 10 Avoid proximity to earthed parts of machinery as this will distort the corona and reduce its efficiency. If bars are needed on both sides of the material, they should be staggered. The bars must be earthed for correct operation. If in any doubt run an earth wire from the bar to the earth stud on the Power Unit.

    Technical and Construction Operating voltage : 4.5 - 7.0 kV Max temperature: 60°C Length : Available in lengths from 80 mm to 4000 mm. Overall length is 60mm greater than the effective length. Cable: 2 metres shielded in flexible conduit; longer lengths can be ordered.

  • Page 12: Maintenance

    Maintenance Ionising bars become contaminated with usage. Dirt build-up on the body of the ioniser and, particularly on the pins, will cause a drop in performance. To get the best from your bar, it should be cleaned as part of regular machine maintenance. Before cleaning, ensure that the equipment is switched off.

  • Page 13: Fault Finding

    Should such an event occur, disconnect immediately and return equipment to the manufacturer for water damage assessment. The Model 915 ionising bar forms part of a system, comprising the bar itself and a Model 904 Power Unit.
  • Page 14 Disconnect all ionising bars from the power unit. Follow the test procedure for the Model 904 Power Unit. This can be found in the instruction manual of the Model 904.
  • Page 15 Using a high voltage probe and meter measure the voltage on the pins of the ionising bar. This voltage should be approximately 6.5 kV. If the voltage is below 4.0 kV then the bar should be returned to Meech for service and/or repair.
  • Page 16 • Attach a short length of insulated wire to either fixing stud on the bar. • Holding the wire insulation, approach any of the bar emitter pins with the bare end of the wire. • As the pin is approached, a small faint spark should jump from the pin to the wire.
  • Page 17 • As the spark is drawn a slight buzzing sound will also be heard. This indicates that the bar is functioning correctly. 8. If there is more than one bar to test, disconnect the first item and repeat the above steps with subsequent bars.

  • Page 18: Repairs And Warranty

    Repairs And Warranty The 915 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 bar directly to Meech Static Eliminators or your local distributor.
