  • Page 5: Introduction

    Introduction The Meech Model 914EX has been designed to meet the most arduous of 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 has been previously possible.

  • Page 6: Operation

    The Power Unit converts the electrical supply into a high voltage, low amperage output. This output energy is transferred to the 914EX bar by the HT cable. The resistively coupled electrodes are energised by the AC voltage from the Power Unit.

  • Page 7: Installation

    Installation The 914EX Bar can be placed between 25mm and 100 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 8 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 905 power unit. Please consult the 905 instruction manual for further instruction.
  • Page 9 4. If bars are needed on both sides of the material, they should be staggered. 5. 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.

  • Page 10: Maintenance

    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 you local Meech distributor.

    Technical and Construction Operating voltage 5.0 kV AC Max temperature 30°C Length Available in lengths of 80 mm to 4000 mm in 25 mm steps. Overall length is 60mm greater than the effective length. Cable 5 metres of HT cable shielded in flexible conduit is supplied as standard.

  • Page 12: Special Conditions For Safe Use

    The 914 EX static eliminator bar shall be used in conjunction with only Meech Type 905 power supplies. The power supply must be protected by a fuse capable of withstanding a prospective short circuit current of 1500A.

  • Page 13: Fault Finding

    Should such an event occur, disconnect immediately and return equipment to the manufacturer for water damage assessment. The Model 914EX ionising bar forms part of a system, comprising the bar itself and a Model 905 Power Unit. (See Fig 2) To verify where a fault may have occurred it is important to test each item of the system individually.
  • Page 14 2. Disconnect all ionising bars from the power unit. 3. Follow the test procedure for the Model 905 Power Unit. This can be found in the instruction manual of the Model 905. 4. Having checked the power unit reconnect one Model 914EX ionising bar.
  • Page 15 5. Using a high voltage probe and meter measure the voltage on the pins of the ionising bar. This voltage should be approximately 4.5 kV. 6. If the voltage is below 4.0 kV then the bar should be returned to Meech for service and/or repair.
  • Page 16 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. „ As the spark is drawn a slight buzzing sound will also be heard. This indicates that „...

    Repairs And Warranty The 914EX 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.
