III. Assembly and Start-up instructions:
The Model 2350™ Digital Dual Cylinder Scale is shipped 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 pedestal, crossbar
and chains, indicator, and reconnect wires to the printed circuit board before scale can be
operated.
Step 1: Remove all parts from box and inspect for damage – bent metal, broken wires, cracks
in indicator, etc. Any shipping damage must be reported to carrier!
Step 2: Place the scale on a solid, dry, and even surface. Clear the area of all debris where
the scale base will be anchored.
Step 3: Open the weigh meter (indicator) and install one black liquid tight fitting in the center
hole. Feed the wire up through the fitting and snug the fitting on the wire. Fasten the indicator
to the post. Connect the wires into the connector using the following code:
TB1 – 1: Common, 4-20mA Return*=Ret TB1- 7: Brown = Br= - Supply Voltage
TB1 – 2: + 4-20mA Output* = Out TB1- 8: Orange = O= + Supply Voltage
TB1 – 3: Green = G= + Signal TB1- 9: Blue = Bl= + Signal
TB1 – 4: White = W= - Signal TB1-10: Yellow= Y= - Signal
TB1 – 5: Black = Bk= - Supply Voltage TB1-11: Common, 4-20mA Return*= Ret
TB1 – 6: Red = R= + Supply Voltage TB1-12: +4-20mA Output*= Out
*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 4: Secure the cross bar to the post using “U” Bolt, Flat washer, lock washer and acorn
nut. Fasten the chain to cross bar with two “S” hooks in the holes provided. The cross bar
should be at the proper height to restrain the size cylinder being used.
Step 5: Allow approximately 15 minutes warm up time before using the scale
IV. General Use Instructions:
There are two separate ways to use this scale. If you know the tare weight (the weight of
the empty cylinder) please use the following procedure:
Begin by allowing 15 minutes of warm up time for the first time use of the scale. With the base
empty, add together the tare weight of the cylinder, plus the weight of any equipment that will
mount on the cylinder, affecting the weight on the scale, and total that number. This is your
