2 Safety Information Read and understand the instructions in this manual before using the device. Keep this manual for future reference. • Include this manual if you pass on the device to other parties. If the device is not used according to the instructions in this manual or if it is modified, the safety of the device may be impaired and Mettler-Toledo GmbH assumes no liability. • • 2.1 Definitions of signal words and warning symbols Safety notes contain important information on safety issues.
en Safety notes WARNING Death or serious injury due to electric shock Contact with parts that carry a live current can lead to death or injury. 1 Only use the METTLER TOLEDO power supply cable and AC/DC adapter designed for your instrument. 2 Connect the power cable to a grounded power outlet. 3 Keep all electrical cables and connections away from liquids and moisture. 4 Check the cables and power plug for damage and replace damaged cables and power plugs.
WARNING Injury and/or damage due to reacting substances When pressure is released from the bottle, the air/gas in the bottle moves back towards the pump. The air/gas coming from the coupled outlets mixes in the pump. Molecules of the substances in the various bottles can get in contact through this contaminated air/gas. 1 Do not connect bottles with incompatible liquids to the same pump simultaneously.
en NOTICE Damage to the instrument The instrument contains no user-serviceable parts. 1 Do not open the instrument. 2 In the event of problems, please contact a METTLER TOLEDO representative. NOTICE D ra ft Damage to the instrument due to inappropriate cleaning methods The instrument can be damaged by certain cleaning agents, solvents, or abrasives. If liquids enter the housing, they can damage the instrument. 1 Only use a wet cloth with water and a mild detergent to clean the instrument or terminal.
3 Design and Function 3.1 Function description The QLX3 liquid module can be added to XPR analytical balances to perform automatic dosing. The liquid dosing head is attached to the liquid module and located inside the weighing chamber. The height of the dosing module is adjusted manually. The QL3 pump and QLL kit for bottle are completing the system. The QL3 pump is used to built pressure in the bottle.
en 3.3 Components description Dosing head holder ErgoClip vial ft The dosing head holder is where the liquid dosing head is secured. The dosing head can be released by pressing the buttons on either side. D ra The ErgoClip vial is used together with vial adapters to hold a vial in place. Those adapters are available for vials of various diameters and heights.
Liquid module ft The liquid module is where the liquid dosing head is attached. It can be moved up and down manually to adjust the distance between the sample vessel and the tip of the dosing head. Top door liquid module ra The liquid module is provided with a top door designed with a slit through which the liquid tube can pass to reach the inside of the weighing chamber. This door is installed in the same railings as the normal door and can be open and closed manually as well as automatically.
4 Installation and Putting into Operation en This instrument must be installed by a METTLER TOLEDO service technician. 4.1 Scope of delivery QLX3 liquid module • • • QLX3 liquid module Top door liquid module ErgoClip vial • • • Various vial adapters, 4 pcs Declaration of conformity User Manual The scopes of delivery for the QL3 pump and the QLL kit for bottles are in the documentation delivered with these products. 4.2 Selecting the location A balance is a sensitive precision instrument.
4.3 Setting up the liquid dosing system 4.3.1 Interface of the pump Front Rear 1 2 5 6 3 4 Air outlets to bottle 4 Socket for AC/DC adapter 2 Pressure release button and indicator light 5 USB port 3 Air exhaust outlet 4.3.2 Wiring the pump ft 1 6 Air inlet The instrument is supplied with an AC/DC adapter and a country-specific power cable. The AC/DC adapter is suitable for use with: 100 – 240 V AC, 50/60 Hz.
en Preparing the liquid tube CAUTION Injury due to leaking liquids Wrongly cut tubing can result in leaking connections. − Cut the tubes with a tube cutter or a sharp knife. § The liquid dosing head is inserted in the liquid dosing head support of the bottle. 1 Using a tube cutter or a sharp knife, cut a sufficient amount of tubing. The appropriate length mainly depends on the distance between the bottle and the dosing module while dosing. Recommended length: about 0.
However, when dosing solutions, molecules of one of the substances might be absorbed by the suction filter, altering the concentration of the solution. The suction filter should only be used when dosing pure solvents. Connecting the air tube WARNING Injury and/or damage due to reacting substances When pressure is released from the bottle, the air/gas in the bottle moves back towards the pump. The air/gas coming from the coupled outlets mixes in the pump.
en 1 Remove the tube adapter (1) from the pump by pushing the connector (2) of the air outlet towards the pump. ð The adapter is released and can be removed. 2 1 2 Remove the air tube from the bottle by firmly pressing down the ring (3) and pulling the tube (4) simultaneously. 3 If necessary, e.g., for maintenance purposes, use the same procedure to remove the air tube from the tube adapter: firmly press the ring and pull the tube simultaneously.
Collecting contaminated air WARNING Injury or death due to toxic substances If you use toxic, explosive, or flammable liquids with the pump, the exhaust air will be contaminated. − Connect a tube to the exhaust air outlet to collect the contaminated air. 3 ft − Connect a tube (1) to the exhaust air outlet (2) to collect the contaminated air into a safe container (3). Note Outer tube diameter: 6 mm The exhaust air tube is not provided by METTLER TOLEDO.
en 5 Operation 5.1 Liquid dosing For further information, consult the XPR Reference Manual (RM). u www.mt.com/XPR-analytical-RM 5.1.1 Installing and removing the liquid dosing head Installing the dosing head ft 1 Slide the dosing head (1) onto the dosing head holder (2) until it comes to a stop. 2 Slightly press down the dosing head until it properly sits in the dosing head holder (2). ð The dosing head is locked in the holder. Check that it is secured by slightly pulling on it.
5.1.4 Handling the bottle CAUTION Injury due to splashing liquids If the pressure in the bottle is not released, liquid might splash when removing the micro dosing valve, opening the bottle, or removing the liquid tube. − Always release pressure before removing the micro dosing valve, opening the bottle, or removing the liquid tube. Filling the bottle The suction filter (1) has to be covered with liquid at all times. Before the suction filter gets dry, refill the bottle. § Pressure is released.
Changing the bottle en If you have more than one bottle equipped with cap and dosing head: § Pressure is released. 5.1.5 Using the QL3 pump 2 3 1 2 1 ft 1 Install the dosing head on the dosing head support of the bottle. 2 Unplug the air tube by pressing down the ring (1) and simultaneously pulling out the tube (2). 3 To seal the bottle, insert the pin delivered with the QLL kit (3) into the air tube connector. 4 Take the new bottle. 5 Connect the air tube to the new bottle.
6 Maintenance Please contact your METTLER TOLEDO representative for details about the available service options. Regular servicing by an authorized service technician ensures constant accuracy for years to come and prolongs the service life of your instrument. For further information, consult the XPR Reference Manual (RM). u www.mt.com/XPR-analytical-RM The appropriate maintenance interval depends on your standard operating procedure (SOP). 6.
en CAUTION Injury due to splashing liquids If the pressure in the bottle is not released, liquid might splash when removing the micro dosing valve, opening the bottle, or removing the liquid tube. − Always release pressure before removing the micro dosing valve, opening the bottle, or removing the liquid tube. § The liquid dosing head is installed on the dosing or liquid module. § A sample vessel is on the weighing pan, big enough for the quantity of liquid in the liquid tube.
5 Remove the fastening nut. Reconnecting the liquid tube Insert the new sealing ring and fastening nut and reconnect the liquid tube.
en 7 Troubleshooting For further information, consult the XPR Reference Manual (RM). u www.mt.com/XPR-analytical-RM 7.1 Error symptoms Error symptoms Possible cause Diagnostic Remedy The liquid dosing head does not dispense any liquid. The suction filter is clogged. Check if there is liquid in the liquid tube. Clean or replace the suction filter. The dosing head is not installed properly. Check if there is a gap between the dosing head and the dosing head holder.
