Assembly and Start-Up:
The Model 2308B
™ Digital Gas Cabinet Scale is shipped partially disassembled. If Cart Option
is selected, it is completely assembled and ready for use. (Please skip to General Use Section).
Assembly instructions are as follows:
The load cells are secured 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 on the wall, or cart if option is
selected. 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 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 placed.
Step 3:
Open the weigh meter (indicator) and install one black liquid tight fitting in the hole.
Feed the 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*
W:
White = - Signal
R:
Red = + Supply Voltage
Bk:
Black = - Supply Voltage
G:
Green = + Signal
*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.
