Page 5: Introduction
Introduction The 924 is now available for use in Ex applications. The 924EX offers the same outstanding levels of performance, reliability, easy maintenance and features associated with Meech Pulsed DC technology. It is ATEX approved and can be used in zone 1 applications. It is designed to control static charges in short range applications and is particularly suited for use in hazardous areas and applications such as gravure printing, film extrusion and coating. -

Page 8: Features And Benefits Of 924Ex
Compact Size and Full Length Ionisation The small cross-sectional size of the 924EX means that it will fit into tight installation positions. The bar has been designed to give full performance over its entire length, ensuring full coverage of webs that run close to machine frames. - Page 9 Shockless Titanium Emitters As with our Hyperion range bars, the 924EX uses Titanium emitter pins. Almost indestructible, these pins will give many years service. For the comfort and safety of the operator, the pins are resistively coupled and shockless to touch.
- Page 10 T-Slot Mounting of the bar is made easy using the T-Slot at the rear of the bar. The M4 T-Bolts used are the same as used on other Meech Pulsed DC bars.

Page 11: Installation
Installation The Model 924EX Bar should be located in the most convenient position so that the pins of the Bar are directed towards the target area. The bar should be positioned to give an unrestricted path for the ions to travel to the target area. - Page 12 Connect ionising equipment using grey HT connections. Next, connect the mains supply to the Pulsed DC Controller and switch ON. The 924EX Bar will now produce Pulsed DC ionisation from the emitters of the Bar. A grounding post on the controller is provided for this purpose. Meech...
- Page 13 WARNING WARNING Meech Pulsed DC Controllers require a grounded 24V DC supply. The 0V line Meech Pulsed DC Controllers require a grounded 24V DC supply. The 0V line must be connected to ground. Failure to do so, will result in damage to the must be connected to ground.
- Page 14 Optimum Frequency Vs Operating Distance for 924EX High Operating Distance (mm) Requires optional BarMaster Remote Programmer. and Pulsed DC Controller If the polarity of the static charge to be removed is known, the balance can be adjusted to give a faster decay speed.
- Page 15 Mechanical Installation The 924EX is a short to mid-range bar. Dependent on the application, the bar will be mounted between 20mm and 200mm from the target surface. The bar should be mounted securely, using all the M4 T-bolts provided with the bar.
- Page 16 When installed at short range over a web or sheet, the bars must be positioned away from surfaces and rollers, as shown in the following diagrams. Your Meech distributor will be able to assist with questions regarding positioning of your equipment.

Page 17: Specific Conditions Of Use
The equipment may not be used in association with dusts having an „ „ electrical resistance equal to or less than 10³Ω.m. The Meech 924EX static eliminator bar shall be supplied only by the „ „ Meech Hyperion 233v4HL Pulsed DC Controller that is set to produce 5.5kV peak maximum. -
Page 18: Operation
Operation Having connected the male grey HT plugs to the power supply, power up the power supply and check the Pulsed DC Controller. The controller will indicate that the bar is running correctly with a good ion output. CAUTION: Always turn off the power supply before connecting or disconnecting the male grey HT plugs. -
Page 19: 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. - Page 20 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. Let dry for a minute and turn back on.

Page 21: Fault Finding
Should such an event occur, disconnect immediately and return equipment to the manufacturer for water damage assessment. The Model 924EX ionising bar forms part of a system, comprising the bar itself and a Meech Pulsed DC Controller. To verify where a fault may have occurred it is important to test each item of the system individually. - Page 22 Disconnect all bars from the controller. Having checked the power unit reconnect one 924EX ionising bar. CAUTION: This test must only be carried out when the installation area is non- hazardous. This may require the bar to be removed from its normal installation position.
- Page 23 If the voltage is well below the output voltage of the DC Controller then the bar should be returned to Meech for service and/or repair. If no meter and probe is available, then a fast and simple test can be undertaken by shorting a pin of the bar to earth.
