Intrinsic Safety Information The Universal MTX pump range • Complies with the EC ATEX Directive 94/9/EC on equipment intended for use in potentially explosive atmospheres, as intrinsically safe to EEx ia IIC T4, for use in Europe. • The equipment may be used in zones 1 and 2 with flammable gases and vapours with apparatus groups IIA, IIB & IIC and with temperature classes T1,T2,T3,T4.
Specifications All models 131mm Weight: 915 g Casing IP rating: IP20 Operating range: 5 - 4000 ml/min (5 - 500 requires adapter) Flow control: ±5% set point constant flow Flow indicator: Scale range 0.5 - 5.5 l/min Battery pack: NiMH rechargeable, 2.0 Ah, 4.
Specifications Pump Features All Models Battery charging options SKC offer two battery charger options for the Universal MTX series pumps, a single charger (Part No. 223-203A) and a five station charger (Part No. 223-103A). Both charger models provide optimum charging of the NiMH battery packs used in the Universal MTX series pumps, based on a timed (16 hour) constant current charging phase followed by a switch to a trickle charging rate to prevent overcharging.
Specifications Pump Features 224-PCMTX4 & 224-PCMTX8 Only LCD screen LCD screen indicates elapsed sample run time in minutes up to 9999 minutes (approximately one week). Also displays operating mode, battery condition and flow fault condition. Elapsed sample time is retained on screen in the event of low battery or flow fault shutdown. Sample hold function Enables pausing and restarting of the pump during a sample.
General Information 1) Pump Models 224-44MTX Standard pump with simple on/off control. 224-PCMTX4 Intermediate pump with on/off control, sample hold and elapsed run time display. 224-PCMTX8 Deluxe pump with full timer control and timer display. 2) Care of Universal MTX Series Pumps • Always use the correct SKC batteries and battery chargers designated for the Universal MTX series pumps. • Never run the pump long term without a tube or filter medium in place.
General Information 3) Non ATEX Certified Variants of the Universal Pump The Universal pumps are also produced in a variant range which is UL certified for intrinsic safety and these pumps are therefore not suitable for use in potentially explosive atmospheres in Europe where ATEX approval is mandatory. Pump components vary between the UL and ATEX certified variants, therefore components must not be interchanged between these pumps. If in any doubt please contact SKC Ltd customer services for advice.

Getting Started APPLICABLE TO ALL MODELS 1) Charging the Battery Pack Prior to first use the battery pack should be fully charged, ideally overnight. The Universal MTX series pumps must only be charged using the correct SKC chargers (Part Nos. 223-203A - single charger, 223-103A - five station charger). The charger is supplied with mains input plugs suitable for use in the UK, Europe, USA and Australia / New Zealand. Select the correct mains input plug and fit it to the charger.
Getting Started 4) Flow Adjust Screw (No. 8) Use the small bladed screwdriver attachment of the supplied toolkit to turn the flow adjust screw. To increase the flow rate turn clockwise. The span of the flow adjust screw is 12 turns. DO NOT FORCE the flow adjust screw, and ensure the screwdriver end is securely located in the adjust screw slot. Use a suitable flow calibrator (such as a rotameter or Defender primary calibrator) to set the required flow rate, do not use the built in flow indicator.
Getting Started APPLICABLE TO MODEL 224-PCMTX8 ONLY 7) SET-UP Key (No. 4) With the pump in hold mode, press the SET-UP key to enter setup mode. The LCD screen will show the legend SET UP DELAYED START and the right hand digit will flash. In the setup mode the delayed start time, sample time and run time can be entered. 8) MODE Key (No.
Operating the Timer (224-PCMTX8 Only) The timer function features three settings used to achieve the various modes of operation: 1. DELAYED START - The time period in minutes that will elapse prior to the pump starting to run. Setting this value to zero disables the delayed start function. 2. SAMPLE PERIOD - The time period over which sampling will occur. Works in conjunction with the PUMP PERIOD.
Operating the Timer (224-PCMTX8 Only) 7. Press the DIGIT SELECT key to select the third digit from the right. 8. Press the DIGIT SET key to increment the digit to 4. The digits should now read 0480. 9. Note that if a SAMPLE PERIOD time is entered, but the PUMP PERIOD is left at 0000, the pump will run continuously for the duration of the SAMPLE PERIOD. 10. The pump is now set up to run for 8 hours and switch off. To start the timed run press the START/HOLD key.
Operating the Timer (224-PCMTX8 Only) 9. Press the MODE key to cycle to the SAMPLE PERIOD setting option. The right hand digit will be flashing. 10. The timer is set in minute values. Calculate the required sample period in minutes - 8 hours = 480 minutes. Thefore the right hand digit should set to 0. 11. Press the DIGIT SELECT key to select the second digit from the right. 12. Press the DIGIT SET key to increment the digit to 8. 13. Press the DIGIT SELECT key to select the third digit from the right.
Operating the Timer (224-PCMTX8 Only) Example: 8 hours running over a period of 24 hours 1. Switch on the pump and enter SET-UP mode. A DELAYED START time can be entered if required. 2. Press the MODE key to cycle to the SAMPLE PERIOD setting and enter 1440 minutes (24 hours) using the DIGIT SELECT and DIGIT SET keys. 3. Press the MODE key to cycle to the PUMP PERIOD setting and enter 480 minutes (8 hours) using the DIGIT SELECT and DIGIT SET keys. 4.
Low Flow Sampling The standard compensated flow range of the Universal MTX series pumps is 1000 to 4000 ml/min. To operate at flows in the range 5 to 500 ml/min an optional low flow adapter / tube holder is required. Low flow adapters are available for simultaneous sampling using one, two, three or four sample tubes (refer to the sampling accessories guide on pages 26 and 27 for details). The low flow adapters incorporate throttle valve(s) to set the low flow rate.
Low Flow Sampling Stand the pump upright on a level surface and set the pump running. Set the pump flow rate to approximately 1.5 l/min. The built in flow indicator rotameter can be used to make this setting as only an approximate flow rate is required. Turn off the pump and enable low flow mode as previously detailed. Low flow adapter No further adjustment of the pump flow rate is required. The low flow adapter can now be connected to the pump inlet hosetail.
Troubleshooting Possible Fault Corrective Action • Check the battery charger by trying it with a different battery pack. Replace the battery charger if required. Battery pack will not charge • Check the battery pack by connecting it to a known good battery charger. If the battery pack still will not charge replace the battery pack. • Check for faulty battery pack by trying a known good battery pack. Pump will not operate Replace the battery pack if required. • Filter media back pressure too high.
Troubleshooting Possible Fault Corrective Action • Battery pack not fully charged before starting sample run. Ensure battery pack is fully charged before starting a sample run. Pump stops due to low battery • Battery pack has reduced capacity as it nears end of life. Replace the before the end of the required battery pack. sample period • Filter media back pressure too high. Try a lower flow rate and/or a less restrictive filter media if the sampling method being used allows this. www.skcltd.
Care of the Battery Pack Battery Charging • Charge battery pack fully before first use to ensure optimum performance. • Full battery capacity will be acheived after 2 to 3 full charge / discharge cycles. • Use only SKC approved charger designated for this battery pack. Use of a non-SKC approved charger may impair battery performance or even cause irrepairable damage, and will invalidate the battery pack warranty.
Care of the Battery Pack Battery Testing 1. Connect SKC approved charger to battery pack. If charger indicator LED illuminates, battery pack charger input is ok. If charger LED does not illuminate, battery pack input fuse is blown - Replace battery pack. 2. Leave battery pack connected to charger to fully charge. 3. If pump does not function at all after full charge of battery pack, battery pack output fuse has blown, or battery cells have failed or are at end of life - Replace battery pack. 4.
