I.General Description: The Model 2310™ Digital Single Cylinder Scale is designed for weighing cylinders 11 ¾ inches in diameter and smaller, with a maximum net weight of 199.9 lb. and a maximum tare weight of 150 lb.The low profile design of the platform (1 ½ inches) allows for safe and easy loading and unloading of cylinders.A crossbar and chain are provided to secure cylinders in place. The printed circuit board contains a power supply section and a separate tare and span control. Theweigh meter electronics are housed in a NEMA 4X enclosure for mounting on wall.

Assemblyand StartUp: The Model 2310™ Single Cylinder Scale is shipped partially disassembled.Assembly instructions are as follows: The load cells are secured to discs and mounted in the base housing.All wire connections in the base have been made and sealed at the factory.The digital weigh meter is assembled and calibrated to the base at the factory.The customer must mount the indicator, cross bar, and chain on the wall.The base must be anchored and secured to floor.The wires must be run through the strain relief, connected to the connector, and plugged into indicator before scale is operated.Steps are as follows: Step 1: Remove all parts from box and inspect for damage – bent metal, broken wires, cracks in indicator, etc.Any shipping damage must be reportedto carrier! Step 2:Clear the area of all debris where Place the scale on a solid, dry, and even surface. the scale base will be anchored. Step 3:the cross bar to the wall using anchors; make sure they are strong enough to Secure safely restrain the cylinder.Fasten the chain to cross bar with two “S” hooks in the holes provided. Thecross bar should be at the proper height to restrain the size cylinder being used. Step 4: Open the weigh meter (indicator) and install one black liquid tight fitting in the center hole. Feedthe wire up through the fitting and snug the fitting on the wire.Fasten the indicator to the wall.Connect the wires into the connector using the following code: TB1 :Ret: Common, 420mA Return* Out:+ 420mA Output* G:Green = + Signal W:White =  Signal Bk:Black=  Supply Voltage R:Red = + Supply Voltage *Connect your wires here if you are using 420mA output.Refer to the wiring diagram on page 5 and 6 for 420mA connections.Jumper J4 will need jumper in the top two pins for loop powered, and the bottom two pins for scale powered (with board oriented as in drawing pg 5.) Insert the wire, being sure not to crimp the insulation in the connector.Using a small screwdriver, push the orange lever down to insert the wire into the proper hole and release the lever to allow the wire to clamp into the connector.The connector holes are labeled according to the color that is inserted there. Step 5: Allow approximately 15 minutes warm up time before using the scale. IV. GeneralUse Instructions: © 2004.Scaletron Industries Ltd. Plumsteadville, PAScaletron.

Please refer to these instructions for daily use of this scale.These instructions simulate the procedure for every day usage. To load a new, full cylinder, please follow these steps: 1. Ifyou know what theTare Weightof your cylinder (the weight of an empty cylinder) you may turn your black tare knob (located on the front of the indicator door) counterclockwise, until the tare weight is shown on the LCD indicator as a negative number.(Ex: Your cylinder is stamped with a tare weight of 100 lbs.You turn your tare knob counterclockwise until it reads “–100”. Thenyou load the cylinder on to the disc, being sure that it is completely on the disc and not touching the base.) Do not load the cylinder on before you have reached the tare weight.Apply the safety chains to the cylinder making sure that they are not too tight as to interfere with the weight of the cylinder. OR 2. Ifyou do not know the tare weight of the cylinder, or if you DO know theNet Weight, (the weight of the contents of the cylinder) you may use this alternate procedure.Load the full cylinder on to the scale base being sure that the cylinder does not sit on the base.When cylinder is centered and safety chains are attached, turn the tare knob, located on the door of the indicator, counterclockwise, until the known weight of the contents is displayed on the LCD. (Ex: You have a cylinder that holds 150 lbs. of contents.Load the cylinder on the scale, apply safety chains, and turn the black tare knob located on the front of the indicator door until the weight of the contents, 150 lb., is displayed on the LCD display.You are ready to start using the contents.) When cylinder is empty, remove chains, remove old cylinder, and load new one using the instructions above. V. CalibrationProcedure: The Model 2310™ Single Cylinder Scale isprecalibrated at the factory to within specified accuracyand is calibrated to standards traceable to the Bureau of Weights and Measures. No further calibration should be necessary.If the electronics or load cells in the base are being replaced, the following procedure should be used. 1. Plugthe AC Cord into a wellgrounded receptacle. There is no power on / off switch, so power is applied as soon as it is plugged in. 2. Allowapproximately 15 minutes warmup time before calibration. 3. Whileindicator is warming up, proceed to check under cylinder support disc to make sure there is no debris. 4. WITHNO WEIGHT APPLIED TO THE SCALE, turn the black tare knob on the outside of the door of the indicator in the clockwise direction to make sure that there isat least+10 lb. of weight in the tare knob.If not, adjust R6 to see a positive reading.Once that is established, turn the black tare knob on the door of the indicator counterclockwise until it stops (DO NOT OVER TURN KNOB OR YOU WILL DAMAGE THE TARE POT!)Once it reaches the most negative reading, make sure you have at least –150 lb. on the display.If the tare span is large, you may get to a –1 reading and this is a weight underload condition.Turn R6 until you see a number a number that is not “below” –199.9 lb. 5. Adjusttare knob on front of weigh meter until scale reads zero with no weight on platform. Adjust R22 to set the 4mA reading to 0lbs.

4 5. Placea known weight on the disc, as close to center as possible.Weight should be equal to ½ of capacity, or greater. 6. AdjustR15 until display reads weight of test weight on scale disc. 7. Tocomplete calibration of 420mA output, adjust R19 for proper 20 mA adjustment reading. Factorysetting is for 20 mA at 150.0 lb (68 kg.) unless specified otherwise. 8. Calibrationis complete if specified accuracy is obtained. VI. Troubleshooting: 1.If display reads: “1”: A.Gross underload.Numbers should reappear and can beTurn knob clockwise. adjusted to tare weight or zero as required. B.Check load cell connections at indicator, and connect wires as per diagram on Page 5. 2. Ifdisplay reads: “1”: A.Gross overload.If starting point was zero, the cylinder weight is more than 199.9 lb., or kg. B.If starting point was –150.0 lb. (68kg.) then the cylinder weight is more than 349.9 lb. (158 kg.).Remove weight and recheck tare setting. C.Check load cell connections according to page 2. 3. Ifno display (not lit): A.Check power to weigh meter. B.Check green light on power supply board.It should be lit.If not lit, it is shorted out. 4. OtherProblems: A.Consult the Factory!
