Before you begin, please notice the programming sheet that comes in the

box with your indicator and instructions. This page tells you the

parameters to which your unit has been programmed. Your unit is

programmed at the factory as it is ordered. If there are incorrect

parameters, please refer to this manual to see how any changes you make

will affect the other options, and the calibration of your unit. It is

imperative that you correctly set the menus in order for this unit to work.

Any changes in the units, decimals, count-by, resolution, and calibration of

the unit will affect the output! If you make any changes to the set-up, you

must record the menus you alter so that you can inform customer

assistance if you call for technical help. Without the changes, our factory

will be trying to advise you using the factory set-up!

Indicator Precautions:

The indicator is sent with a door latch, and the door will have two screws holding

the door shut. Those screws are to be removed in order to insert the

connections to the various connectors in the box. When connections are

complete, and the indicator door is latched closed, you must reinstall the screws

that hold the indicator door closed. The power cord is attached at the factory

using a liquid tight fitting. Do not modify or restrict the ability to disconnect the

power cord from the outlet. Connections for bases using other fittings or conduit

must be made in the field. Please take care to not damage the internal

components when drilling a hole in the indicator box. All holes drilled MUST be

sealed so that gasses and liquids cannot penetrate the box and damage the

internal electronics. Do not drill holes where the internal cables are located. If

there is a gap or opening in the box that isn’t sealed by the connector, use a

silicon caulk to seal the opening from exposure. Please use fittings that are

liquid tight fittings and are rated for NEMA 4X conditions. Do not use any type of

conduit fitting or other fittings that do not have a tight seal to the indicator.

Damage may occur if gasses and liquids have access to the electronics! The

mounting location of the indicator should be at operational level, away from the

floor. Indicator is a NEMA 4X rated enclosure; however, it is not designed to

withstand wash-down procedures, or chemical contact beyond accidental

exposure. Please choose a location that will protect the indicator from direct

contact with chemicals, or regular soaking of water. Indicator is mounted to wall

using the four holes in the tabs on the indicator box.

If the indicator is mounted in a way that does not comply to the standards above,

the resulting damage will not be considered for warranty repair, and may cause

substantial damage to the electronics.

If the indicator should require cleaning, a cloth damp with water would be

recommended to wipe the display and keypad area, as long as the chemical

conditions can allow for it. Due to the fact that the chemical environment in

which the 1020™ may be located, can vary greatly, we cannot identify one

specific cleaner to maintain the indicator. You must use your own discretion

when cleaning with any substances. Mild cleaners should not affect the indicator

box. Harsh or abrasive cleaners are NOT recommended for use as they may

etch or scratch the finish on the mylar or enclosure.

Before making connections, it is wise to plug the indicator into a power source to

confirm that the indicator is in working order. If the indicator is functioning

properly, you will see the LCD display flash a Model number and version number,

and then after a few seconds, it will proceed to the Net Weight screen. If one

channel is active, the screen will display:

#1 _ _ _ _ _ _ _ _0 _ (Units).

With two active channels, the display will show:

#1 _ _ _ _ _ _ _ _ 0 _ (Units)

#2 _ _ _ _ _ _ _ _ 0 _ (Units)

Please disconnect the power before making all internal wiring connections!

In order to start the Model 1020™ 5 Digit Indicator, you must first install the

bases according to their instructions. Please refer to the Base Installation portion

of the Instruction Manual found on the last page of the manual, for the safe and

correct installation of your new base(s). The Orientation Diagram on page 10 will

operator’s menu. There is a Select key ∗ and an up and down arrow keys

that are used to select, or scroll, respectively. The arrow keys can be pushed

and held to scroll. The longer the button is held, the faster the numbers will

scroll. The unit is shipped from the factory fully calibrated and configured to the

specifications on the purchase order, but values for 4-20mA are easily changed

in the set up mode. Bases and indicators are matched and calibrated to a

specific channel to provide the highest level of accuracy. After connections have

been completed and the base installation and optional equipment is connected,

please refer to the following procedure for start up and general use directions.

To begin, determine your method of use. Will you load a full container on the

scale base, or will you be filling an empty container and using product? Choose

the proper method of use section and following the instructions.

Load Tank Method:

When using the method of loading full containers onto the scale frame, you

should use the following procedure.

Apply power to the indicator by plugging the indicator into a wall power source.

When indicator is in start-up, it will flash a display that shows the Model number

and the version of software. The indicator will then display the active channels in

the format of NET WEIGHT. One channel will be displayed if that is the only one

active, or if two are active, each line will display a net weight reading.

To begin, press the select key ∗ to see channel #1 with a bar graph display

depicting a graphic representation of full scale. Pressing select ∗ again will

display channel #2 with a bar graph display depicting a graphical representation

of full scale (if second channel is active).

Press the select key ∗ again to see the “Tare Adjust” screen for the channel #1.

If there is any residual weight displayed on the screen, begin by adjusting the

arrow key to see zero.

If you know the tare weight of the container you will be placing on the base,

follow this procedure:

From the screen that says: #1 _ _ _ _ _ _ _ 0 _ (units) (Net), TARE ADJUST

You will use the arrow keys to set the screen to read in the negative, the amount

of tare weight you will apply to the scale. This may include any other equipment

in addition to the empty container weight. Set the weight using the arrow keys to

read that number negative, and then load the container onto the scale. Press the

select key ∗and repeat the procedure for the second channel if active.

Press the Select key again ∗to see the gross weight screen. This will be the

tare weight you adjusted PLUS the net weight. One or two channels may be

displayed. Press Select∗again to return to the net weight screen.

Procedure is complete. Repeat as you change containers.

If you are loading containers when the tare weight is not known, or if you

prefer to use a known net weight, follow this procedure:

From the Net Weight Screen, Press Select ∗ key to see the channel #1 Net

Weight screen with bar graph. If second channel is active, Press Select ∗ key

to see the channel #2 Net Weight screen with bar graph (of if not active, menu

will continue as follows). Press Select ∗ key to see the TARE ADJUST screen.

Place the container onto the scale base and adjust the net weight showing on the

screen to the correct amount. Use the down arrow to reduce the weight to that

proper net weight amount. Press Select ∗key again to adjust the second

channel if active. Press Select ∗once more to see the Gross Weight screen.

Press Select ∗one more time to return to the Net Weight display.

The following procedure is for applications where a container will remain

on a scale base and be filled and emptied.

Fill Tank:

When operating in Fill Tank Mode, it is imperative that this procedure is followed

to assure proper readings of the weight.

For use the FIRST time, user should place the scale into its permanent position,

V. Troubleshooting: Please DO NOT ATTEMPT TO ALTER OR RE-CALIBRATE

THIS INSTRUMENT ON YOUR OWN UNLESS INSTRUCTED TO DO SO. IT

HAS BEEN CALIBRATED AND TESTED BEFORE IT LEAVES THE FACTORY.

Should you experience trouble, please read the following for easy diagnosis, and

then call the factory for assistance.

If “88888” appears for net weight: This is a condition of overload in weight.

The most likely cause is that the weight on the scale exceeds the net weight that

was configured for the base. Go through each step in the Set-up menu to verify

that chosen options are correct.

If indicator is not receiving any power: DO NOT, AT ANY TIME, STICK

ANYTHING INTO THE OPEN FRAME POWER SUPPLY OR TOUCH THE

COMPONENTS! YOU CAN RECEIVE A SHOCK!!!!! Check outlet for power.

Check to see that scale is plugged into an outlet with the proper voltage. Check

the small green light on the power supply board (on the top right corner of the

Interface board in the back of the indicator box) to make sure it is lit (not

blinking). If the light is completely out, or blinking, the problem exists in

something before the power supply, or something is placing the power supply in

“current overload”. Try disconnecting power, and removing all other equipment

other than the scale base wires and the power cord (this means 4-20 equipment

and relay connections). Plug unit back into power to see if this fixes the situation.

If it does, the problem is not with the 1020™. Check the 4-20mA hook-up to be

sure that the power supply to the 4-20 circuit is within the correct range.

Reconnect one piece at a time to isolate the problem. The power supply’s safety

shut down will cause it to beep and blink the green light. If this starts to happen,

remove power quickly and fix problem. If problem persists, call the factory about

the problem and describe the condition to a technical advisor.

If the 4-20mA reading is incorrect: This 4-20 circuit is Loop powered, so a

supply of power of 18-30 VDC must power the 1020™. Please refer to the

diagram on page 10. Check to make sure the wire insulation is not pinched in

the connector. Wires should stay in the connector even if you gently tug on the

wires. Insert the wire so that it makes good connection. Check to make sure the

scale has been configured properly in the SET-UP Menu. If the problem persists,

please take note if you have a reading of 4mA or 20mA without changing

regardless of weight, or if there is a reading of 0 mA. This will be important in

diagnosing problem.

If the level indicating relay is not working: check to make sure the wire

insulation is not pinched in the connector. Make sure the indicator is

programmed properly in the Set-up menu. Check the setting of a HI or LO set

point to see if relay is configured to act properly. Relay will be NO or NC

depending on connection. Please refer to Orientation Diagram for relay

connections. If problem persists, call the factory.

If problems persist, PLEASE CALL THE FACTORY! If in the U.S.A., call: 1
