I. General Description:

The Model 4042™ and 4042WB™ Secondary Spill Containment Scale is designed specifically

with a built-in containment basin. Off center loading or solid materials do not affect the scale

accuracy due to the four cell design. Mixers and pumps may be used with this base design.

Different base sizes are available, as well as custom bases for different size platforms and

large capacities. The maximum net weight is 199.9 lb./ or kg. with 0.1 lb/ or kg resolution, or

with a maximum net weight exceeding 199.9, the decimal is blanked at the factory, and the

display can read 1999 lb/ or kg. on the standard, 3 ½ Digit indicator.

The design of the platform includes sturdy four point support, with a polyethylene containment

basin. The base is coated with dry polyester powder coating to prevent corrosion. Scale has

four temperature compensated strain gauge transducers.

III. Assembly and Start-Up:

The Model 4042™ and 4042WB™ Secondary Spill Containment Scale is shipped partially

disassembled. Assembly instructions are as follows:

The load cells are secured to the base. 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. The base should be roughly

leveled using the adjustable foot in the load cell. The wires must be run through the strain

relief and connected to the connector 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.

VERY IMPORTANT: If Model 4042WB™, make sure that expandable bladder has room

and clearance to expand without coming into contact with any other objects that may

cause a leak or obstruct proper expansion o the bladder!!!

Step 3: If conduit is to be used, we recommend at least 2 feet of FLEXIBLE conduit

horizontally, as to not interfere with free movement of the base for accurate measurement.

Feed the wire up through the conduit, and apply a fitting.

Step 4: Drill a hole in the indicator, being sure to avoid the PC board, and completely seal the

hole with the fitting. If ANY SPACE exists around the fitting allowing gas into the box, the

equipment will be damaged. You MUST SEAL any openings with a flexible caulk, such

as silicon! 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. General Use Instructions:

Please refer to these instructions for daily use of this scale. These instructions simulate the

procedure for every day usage.

ON AND OFF LOADING USAGE:

To start with a new, FULL tank that will be loaded on & off, please follow these steps:

Please choose a method of usage by Tare or Net Weight:

TARE: You must know the weight of your empty tank, and any other equipment mounted on

to the tank that will affect the weight. Add this weight together, and turn the black tare knob on

the front of the indicator until it reads that number in the negative. Turn the knob counter-

clockwise in order to achieve negative numbers. Once that negative tare weight is set, you

may load the tank, and apply other equipment on that tank. The weight that registers on the

scale indicator is the NET WEIGHT, or weight of the contents. At this point you will not change

the black tare knob unless you are loading on a new tank. As you use the contents, the weight

decreases. When the tank is at zero, or close to it, you will begin again by removing the empty

tank, setting the tare weight with the black knob (for the new tank + equipment), and begin

using the material again.

NET: If you do not know the tare weight (it is not stamped on the tank), you may know the Net

Weight (contents in the tank). If this is the case, you will use this procedure:

Load on your full tank and attach any equipment that affects the weight on the scale. Turn the

black tare knob on the front of the indicator until it reads the known NET WEIGHT (weight of

contents only) on the indicator. Clockwise will increase the readings and counter-clockwise

will decrease the readings. When the weight is set for the contents in the tank, do not adjust

this again until you load on a new tank. The reading will decrease until you have used all the

contents in the cylinder, where it will read 0 lb./kg. Start a new tank by removing the old empty

tank, loading on a new full tank, and attaching equipment, and set tare knob to Net weight

again.

For use when FILLING the TANK instead of on & off loading:

To start with a new, EMPTY tank that will be filled while on the scale base, please follow

these steps:

Load the new, empty tank on to the platform. Be sure to connect all equipment to the tank that

may apply weight to the scale. With this weight applied, turn the black tare knob located on

the outside, front of the indicator, until the digital reading says zero. This means that your

digital reading will show net weight, or the weight of the contents alone. As you fill the tank for

the first time, the scale shows the current weight at all times. Do not readjust the tare weight

unless you are starting with a dry, new, empty tank. Any residual weight will reflect what is left

in the tank, and should not be changed unless a new tank is put on the base.

V. Calibration Procedure:

The Model 4042™ and 4042WB™ Secondary Spill Containment Scale is pre-calibrated at

the factory to within specified accuracy and 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. Plug the 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. Allow approximately 15 minutes warm-up time before calibration.

2310, Model 2330, Model 2350, Model 2352, Model 2353, Model 3001, Model 3002, Model 3001 SI, Model 3002 DI, Model 3003, Model 3004, Model 3005, Model 3006, Model 3050-1,

Model 3050-2, Model 4010, Model 4020, Model 4021, Model 4030, Model 4040, Model 4042, Model 4042WB,Model 4041, Model 4042, Model 4042 WB, Model 5305, Model 5305-2, and

3. While indicator is warming up, proceed to check under cylinder support disc to make sure

there is no debris.

4. WITH NO 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 is at 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 the amount of tare weight that you require for

the tanks/drums that you will use on this platform. If the tare span is very 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 or 1999 lb.

5. Adjust tare 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.

6. Place a known weight on the disc, as close to center as possible. Weight should be equal

to ½ of capacity, or greater.

7. Adjust R-15 until display reads weight of test weight on scale disc.

8. To complete calibration of 4-20mA output, adjust R-19 for proper 20 mA adjustment

reading. The customer specifies the factory setting for 20 mA at the time the order is placed. It

should have been assigned to the net weight of your intended product. Consult white “4-20mA

settings” sticker on inside of indicator!

9. Calibration is complete if specified accuracy is obtained.

VI. Troubleshooting:

1. If display reads: “-1”:

A. Gross under-load. Turn knob clockwise. Numbers should reappear and can be

adjusted to tare weight or zero as required.

B. Check load cell connections at indicator, and connect wires as per diagram on Page

2. If display reads: “1”:

A. Gross over-load. If starting point was zero, the cylinder weight is more than 199.9

lb., or kg. with the decimal, or 1999 lb./kg. without the decimal.

B. Check load cell connections according to page 2.

3. If no 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. Other Problems:

A. Consult the Factory!
