EI-1000 and EI-2000: Installation and wiring.

1. Chose a mounting location for the scale base and instrument. WT3600,
ECS150x, LP4310, and any scale that has a hinge at one end must be
bolted down before use. The DCS-302, EDS-400, C3600, C7200 and DS­750 should be bolted down for best results.

2. Mount instrument and scale base. See the instrument and scale manuals
for drawings if needed.

3. Wire scale base. Use TB4 on EI1000 units. See Scale Wiring section for
details. The EI-1000 has a shorting jumper on TB5 (+S,-S,-E). Do not
remove this jumper.

4. Check S2 and set for the proper power input voltage 230 or 115 V.A.C. S2
is directly above the power terminal TB1.

5. Wire up A.C. Power on TB1. G is earth ground. N is Neutral or L2. H is
Hot or L1.

6. Wire 4-20 outputs, if needed, on TB3. CH1 is the left display. CH2 is the
right display. The EI-1000 uses CH1.

7. Power up unit. The instrument should show a weight reading if everything
is wired properly. If the instrument shows A-OL, double check the scale
wiring. See the alternate color codes table below for the 4 possible color
codes.

8. When the scale is showing a weight reading, push down on the deck or
disk. The gross weight should go positive. If the reading goes negative,
reverse wires on the +S and –S terminals and recheck.

9. Calibrate the system. See the next page.

10. Setup and calibrate the 4-20 mA outputs if needed.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Calibration: If you are using a permanently mounted tank, see the Day tank
setup section and follow the calibration instructions there. To enter the

calibration mode:

EI-1000: Press and hold [SELECT] + [RIGHT ARROW] for greater than three seconds.

EI-2000: Press and hold [LEFT SELECT] + [RIGHT SELECT] for greater than three seconds.

1. The display will show “CFG” (EI1000) or “SEL CFG” (EI2000). Use the up
arrow to change “CFG” to “CAL 1” (1000) or “CAL” (2000). Press SELECT
(1000) or the right SELECT (2000). The display will show the gross weight
with the GROSS light flashing.

2. Remove all weight from the scale. If you are using a tank that will be
permanently mounted on the scale it can be left on the scale. Make sure
the tank is empty or pumped out to it’s lowest point.

3. Press the ZERO pushbutton to zero the instrument. On the EI-2000 use
the ZERO button on the side you are calibrating. NEVER use the arrow
keys to zero the scale. If you do so by accident, unplug the power to the
EI before exiting the calibration mode. This will prevent the zero from
being saved.

4. Place a known weight on the scale that is 10% or more of the scale’s
capacity. If you are using a scale with a stop across the back, place the
weight all the way against the stop. On all other scales, roughly center the
weight on the deck or disk. On bases designed for 150 pound or ton CL2
cylinders, calibrate with a full cylinder for best results. If using a day tank
place a known weight in the center of the tank or fill the tank with a known
amount of water or the actual chemical you are using and calibrate.

5. The instrument should show a positive reading. Use the up or down
arrows to set the correct gross weight. On the EI-2000 use the arrows on
the side you are calibrating.

6. On the EI-2000, repeat the calibration on the other side.

7. Press the right arrow twice on the EI-1000 to exit the menus and return to
the gross weight reading. On the EI-2000 use the left SELECT.

Recommended: After correct operation is verified, use the diagnostic mode to
write down the values of parameters 1.o, 1.c, 2.o, 2.c. These store the calibration
information. If the calibration or zero is altered these numbers can be reentered
to restore it.

Operation in automatic modes 3 and 4:

1. Zeroing: Starting with an empty scale showing the gross weight, press the
zero button if the reading is not zero.

If the scale shows “n0 0” the weight exceeds the push to zero percentage
(parameter P114). See the calibration section to zero the reading.

If nothing happens double check that the GROSS light is lit. Use the select
button to show the gross weight if needed. Press zero again. You may not
be in mode 3 or 4 if the instrument still won’t zero. See the calibration
section to zero the reading.

2. Place tank on scale. Check that the gross weight is correct. (Gross = Tare +
product in tank). You may have to wait a few minutes for a stable reading while
the contents of the tank to settle.

3. If the gross weight is not correct and the GROSS light it flashing, use the
UP/DOWN arrows to adjust the weight.

If the GROSS light is not flashing, hold down the select button a few
seconds until it does.

4. Press select.

Instrument will show the tare weight in operation mode is 4. Go to step 5.

Instrument will show the correct remaining weight if the operation mode is

3. You’re done! (Partial tank see below.)

5. Use the UP/DOWN arrows to set the correct tare weight if needed.

6. Press select to save the tare and show the remaining weight.

Partial tank notes:

Assume the gross weight is correct in steps 2 and 3. If using mode, 4 continue
normally. The remaining weight will be correct.

Mode 3 will show a full tank in step 4. To fix: hold down the UP arrow while the
remaining weight is shown. The reading will jump to TARE after several seconds.
Use the UP/DOWN arrows to set the tare weight. Press SELECT when done.

Scale Wiring:

Color codes vary depending on the scale type and load cells used. All four
codes can be tried without damaging the scale or the instrument.

All Eagle Microsystems scales with orange and blue wires use code A.

Code A works with the LP4300, LP4320, WP1000, WT3600, C3600 &
7200, EDS400, most scales with four mounting feet, and our hydraulic
conversion kits with the round load cell (HC3600 & 7200).

Code D or B works with the ECS150x/400 series scales. Try these codes
with any scale with a hinge and a single load cell mounted on top of the
deck. Note: If an ECS has a color code printed on the cable use it but
swap the +S and –S colors!

Code C works with the LP4310, scales with a hinge and cell mounted
inside of the deck, and our HC1000 hydraulic conversion kit.

If your scale or load cell was not obtained from Eagle Microsystems, try
code C or A first. You may want to contact the manufacturer for the color
code. You can also call us with the make and model of the scale and we
may be able to find it for you.

If the instrument shows a weight but the gross reading goes down when
weight is applied, swap the wires on the + and - S terminals.

If the instrument reading is unstable, check for loose connections.

Troubleshooting:

Instrument doesn’t power up:

• Check the ribbon cable between the display and the CPU boards. It
should be plugged in all the way and have the red line next to the pin 1
markings.

• Unplug the power. Check that S2 is set for the proper input voltage.
Change it if needed and plug the unit back in.

• Use a multimeter to measure voltage at the H and N terminals on TB1.
There should be approximately 115 or 220 volts A.C. coming in. If not,
power is not reaching the instrument.

• Unplug the power. Measure the resistance across the plug. An EI set for
115 VAC should read near 70 ohms and a 230 VAC unit should read near
275 ohms. If not check the fuse located in the black fuseholder with a
slotted screwdriver top (directly below the transformer).

• Measure the + & - E terminals on TB4 or TB5 with the power on. You
should have 5 volts DC across them. If 5 volts is present, double check
the ribbon cable and J3 on the CPU board. If 5 volts is not present, unplug
the instrument, disconnect the scale(s) and plug the unit back in. If it
powers up now there is a short in the scale wiring.

• The jumper on J3 should be below the 1 (right side) for an EI-1000 and
below the 2 (left side) for the EI-2000.

EI-1000 display shows gibberish:

• Check J3 as shown above. If you ordered both EI-1000’s and 2000’s you
may have accidentally swapped displays.

EI-2000 display lights up the 8 LEDs but not the digits:

• The ribbon cable is plugged in backwards on one end.

Display is very dim:

• Unplug unit and check S2. If it is set for 230 VAC and you are running it on
115 this may happen.

• If S2 is ok, disconnect the scale(s) and plug the unit back in. If the display
is now bright there is a short in the cable or scale base. Check the cable
to the scale(s) for any point that may have been smashed or pinched
during installation.

• Measure the AC input voltage with a meter, it may be too low.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Page 9 of 19

Display shows, “n0 0” when the zero button is pressed.

• The zero button is limited in normal operation to prevent someone from
accidentally zeroing a full scale. To bypass this error if needed, go to the
Calibration section. Enter the cal mode and do steps 1,2,3 and 7.

• Faster way! If the front cover is open close dip switch #4. The gross
light(s) will flash. Press the zero button. Open switch #4. Done!

Display stays at zero or goes up slightly when placing a know weight on
the scale

and/or

Unstable weight readings:

• On the DCS-302 or DS-750 the shipping nut or bracket may not have
been removed. Flip the deck over. The nut or bracket is located under the
square box and holds the long lever(s) up against the deck.

• The EDS-400 uses foam to hold the long lever up against the deck for
shipping. Flip the deck over and remove the foam if it’s still there.

• On any scale with a hinge and a load cell mounted on top of the deck,
make sure the foot is sitting on the floor and the bolts mounting the load
cell are not touching the floor.

• On the EI-1000 with a single scale the scale should be wired to TB4
(seven position terminal).

• The EI-1000 comes with a jumper shorting the +S,-S, and –E terminals on
TB5. If it was moved to TB4, replace it on TB5

• The LP4310 and LP4300 have adjustable feet. Make sure the foot has not
been backed out so far during leveling that the threaded rod is hitting the
underside of the deck.

• Recheck the wiring. If the +E wire comes loose or is broken it can cause
the instrument to stay at zero. Check the load cell and instrument cables
for any damage.

• Measure the + & - E terminals on TB4 or TB5 with the power on. You

should have 5 volts DC across them. If 5 volts is not present, kill the
power. Disconnect the scale(s). Apply power and measure the + & - E
terminals on the CPU board. If 5 VDC is present the scale or wiring has a
short. Note: If you measure 10 Volts, that’s OK. Older indicators had 10 VDC excitation.

• Make sure there isn’t anything stuck under the scale and the sides of the
scale are not rubbing against anything.

• Check the corner readings on any scale with four load cells or four feet
(Ex. LP4300, WP1000, C3600, C7200 ). Place a weight on one corner at a
time. The corner with the lowest reading most likely has a mechanical or
electrical problem. A corner that reads high may also have electrical
problems such as a wrong load cell or bad summing box.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Page 10 of 19

Display stays at zero when chemical is pumped into the tank but increases
if the scale is stepped on or a test weight is applied:

• Turn off the automatic zero function. (Set parameter P113 off.) See the

Changing Configuration Parameters and day tank setup section for
more info.

If the weight reading starts drifting wildly or shows OL, UL, or A-OL:

• Check the cable from the scale to the instrument for damage.

• Check the wiring in the instrument for broken or loose connections.

• The LP4320, LP4300, and most multiple load cell scales have a summing

box mounted under the deck. This box will need to be opened and
inspected for moisture or corrosion if the cable looks good.

• On all scales with a summing box, inspect the connections inside the box
for loose or broken wires. Also check the cables from the load cells to the
summing box for damage.

If the weight reading doesn’t track properly:

• Inspect the scale and tank to make sure they are not rubbing against
anything.

• Check that all piping to the tank has a flexible section to allow the tank to
move.

• Check under the scale to see if anything is stuck there.

• Check that the adjustable feet have not been backed out so far that they

are hitting the underside of the deck.

Remaining weight is wrong but the gross weight is correct:

• Press SELECT several times. If you can select the tare weight use the
UP/DOWN arrows to change it.

• If you cannot get the tare weight to show, select the remaining weight.
Hold down the UP arrow. After about three seconds the unit will jump to
the tare weight and start scrolling. Release the button and use the
UP/DOWN arrows to set the tare. Press SELECT when finished.

• If that doesn’t work you have an older indicator. Enter the configuration
mode by closing dip switch S1 position 1. Set parameter P001 to “1”. This
selects the manual mode. Open the switch and you will be able to select
the tare. Note: On old style EI-1000’s hold down SELECT until “nOnE” flashes. Press

UP to get to “CFG” and press SELECT to get to “P001”. Hold down “SELECT” until
“DONE” appears to exit.

4-20 mA parameter setup:

• Enter the configuration as shown on page 9.

• Use the UP arrow to get to P600. This sets what the 4-20 output follows.

• The selections are: Gr - gross weight, rE - remaining weight, GT - gross

total, rT - remaining total. “Total” modes transmit the sum of both sides of
the display on channel 1.

• EI-1000 - Press SELECT and use the arrows to change the value if
needed. Press SELECT again.

• EI-2000 - Use the right arrows to change the value if needed.

• Now go to parameter P610. This set the weight value that equals 20 mA.

• Change the value if needed as shown above.

• See “4-20 mA output testing” for calibrating or testing if needed.

4-20 mA output testing:

EI-1000: Press and hold [SELECT] + [RIGHT ARROW] for greater than three seconds.
EI-2000: Press and hold [LEFT SELECT] + [RIGHT SELECT] for greater than three seconds.

• Use the arrows to get to “AOUT”. Press SELECT.

• “Ao.test” (EI-1000) or “Ao T 4.00” (EI-2000) will be displayed.

• If using an EI-1000 press SELECT and “4.00” will start to flash.

• The output is now forced to 4 mA. Connect a current meter or check the

remote readout to check the output.

• Using the arrows (right side on EI-2000) will force the output to the value
shown.

• Go up to 20.0. Check the output is 20mA or full scale on the remote
readout.

• Go to 12.00 mA. Check the output is 12mA or half scale on the remote
readout.

• On the EI-1000 press SELECT when done to return to Ao.TEST.

Calibrating the 4-20mA outputs:

Enter the configuration as shown above and select “AOUT” as shown in the first step.

1. Go up to “Ao.1 4“ (“Ao.1 4.0” on EI-2000, use the left arrows.)

2. Connect an mA/current meter capable of displaying 20.00mA to

0.01 mA to CH1 output.

3. On the EI-1000 press SELECT. The “4” will flash.

4. Use the up/down arrows to set the output to 4.00 mA on your
meter. The readout on the indicator will not change. (Use right
arrows on EI-2000)

5. On the EI-1000 press SELECT. The “4” will stop flashing.

6. Use the up arrows (left on EI-2000) to get to “A.o 1 20”

7. Press select on the EI-1000.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Page 13 of 19

8. Use the arrows to set the output to 20.00 mA on your meter.

9. Press select on the EI-1000 to stop the flashing and save the
value.

10. If needed, now hook your meter to CH2 output.

11. Go up to “Ao.2 4”

12. Repeat steps 3 through 9 using the Ao.2 prameters to set the
channel 2 output.

13. Use the left SELECT button or the right pointing arrow on the
EI-1000 to exit all the way back to the weight reading to save
the new calibration.

Setting the zero and full scale on your remote readout:

Enter the configuration as shown on page 9.

• Use the arrows to get to “AOUT”. Press SELECT.

• “Ao.test” (EI-1000) or “Ao T 4.00” (EI-2000) will be displayed.

• If using an EI-1000 press SELECT and “4.00” will start to flash.

• Go to 4.00 mA. Zero your remote readout if needed.

• Go to 20.00 mA. Set your remote readout to full scale.

• On the EI-1000 press SELECT when done to return to Ao.TEST.

4-20 mA troubleshooting:

Go through the output testing as shown above.

• If you find any trouble when using a DMM, check your meter against a
known good 4-20 output to verify it is functioning properly. Worn test leads
may not make a good connection and cause low readings. We’ve also
found some low cost digital meters do not read low DC currents properly.

• If there is no current output, set your meter to volts DC. Measure the
output. If you have a reading of 10 VDC or higher the current fuse in your
meter may be bad.

Remote readout isn’t working:

• The EI1000/2000 is an active or sourcing output. Check that your remote
is set as a passive input.

• Disconnect the loop and hook a meter up to the output directly. Check the
4,12, and 20 mA points again. If the output works now any problems are in
the remote readout or the wiring.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Page 14 of 19

Remote readout shows proper values in test mode but doesn’t track the
weight shown by on the indicator’s display:

• Check the P600 and P610 settings as shown in the “4-20 mA parameter
setup” section. P600 selects gross or remaining weight tracking and P610
sets the weight that will be 20mA.

Note: The reading displayed on the remote will be within 1% of the reading on
the EI1000 or EI2000.

Remote readout changes during testing but doesn’t track properly.

• Check that your remote is set as a passive input. If it’s sourcing current it
may be “fighting” the EI’s analog output.

• Calibrate the 4-20 mA outputs as shown above.

• Go through the output test again and check the output values with a

meter.

• If this tests ok then set the zero and full scale on your remote readout as
shown above.

Remote readout doesn’t change or no current output.

• If there is any current from the output but it is “stuck” and won’t follow the
test readout, the output is bad. The chips are socketed and can be
replaced in the field. U7 drives the CH1 output and U8 drives CH2. It may
be best to send the EI1000/2000 in for repair as there may be other failed
components.

• If there is no current output, set your meter to volts DC. Measure the
output. If you have a reading of 10 VDC or higher check the current fuse in
your meter. It may be bad.

• If your meter doesn’t show any voltage in the above step, the output is
blown. It may be The U7 or U8 chips as in the first step above.

• If the 4-20 output doesn’t change when reading weight but works in the
test mode there is a setup problem. Check the P600 and P610 settings.
Also check the tare and remaining weights if P600 is set to rE or rT.

Output current is stuck over 21 mA or under 3.4 mA but not zero.

• The output chip is blown. The chips are socketed and can be replaced in
the field. U7 drives the CH1 output and U8 drives CH2. It may be best to
send the EI1000/2000 in for repair as there may be other failed
components.

Day tank use – Instrument setup:

If you are using a day tank you must set parameter 113 to off. This is the auto
zero. If this parameter is not turned off the instrument will zero out the reading as
the chemical is pumped in. If the instrument skips over P113 set P100 to USER
and P113 will appear in the menu. If parameter 213 is available set it to off as
well. See the Changing Configuration Parameters page for an example.

The operating mode of the EI1000 or 2000 should be set to fully manual (P001
set to 1).

Set the tare weight to 0. On a day tank application the gross and remaining will
show the same value.

All piping to the tank must have a flexible section to allow the scale and tank to
move. If any pipes are rigidly attached it will affect the accuracy of the scale.
Install a flexible section if needed. Do not allow the tank or scale to bear the
weight of any piping.

Unless the pumps can completely empty the tank, there will be some product left
in the bottom. This residual can be ignored. The weight will show how much
usable product is left in the tank.

The instrument can be calibrated to read in gallons instead of pounds if desired.
Make sure to clearly mark “Gallons” on the instrument face to avoid any
confusion if you do this.

On the LP4300 or any scale with four load cells you can place known weights on
the top of the tank to calibrate they system instead of adding product. Use
weights totaling at least 10% of the tanks capacity. This won’t work with the
LP4310 and LP4320.

If the display stays at zero when chemicals are pumped into the tank, double
check parameter P113 (auto zero) is OFF. A quick test is to put a weight
between 2 to 5 pounds on the scale. If the instrument goes to zero within 20
seconds this parameter is on. See the Turn off Auto Zero section.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Page 16 of 19

Calibrating an empty day tank.

Any auto zeroing (parameter 113 on EI series) must be set to off when using a
day tank! Check this before continuing.

If the tank can be emptied or is empty, use this procedure. If it can’t, follow
the next procedure.

1. Enter the calibration mode.

EI-1000: Press and hold [SELECT] + [RIGHT ARROW] for greater than three seconds.

EI-2000: Press and hold [LEFT SELECT] + [RIGHT SELECT] for greater than three seconds.

2. The display will show “CFG” (EI1000) or “SEL CFG” (EI2000) Use the up
arrow to change “CFG” to “CAL 1” (1000) or “CAL” (2000). Press SELECT
(1000) or the right SELECT (2000). The display will show the gross weight
with the GROSS light flashing.

3. Pump the tank out as far as possible. Do not run any pumps dry if this will
cause damage.

4. Press the ZERO pushbutton to zero the instrument. On the EI-2000 use
the ZERO button on the side you are calibrating. NEVER use the arrow
keys to zero the scale. If you do so by accident, unplug the power to the
EI before exiting the calibration mode. This will prevent the zero from
being saved.

5. Add a known amount of product (at least 10% of the tank’s capacity) to
calibrate. The weight reading should rise while the product is being added.
If it doesn’t, stop! Further troubleshooting is needed.

6. The instrument should show a positive reading. Use the up or down
arrows to set the correct gross weight. On the EI-2000 use the arrows on
the side you are calibrating.

7. To verify the calibration, add another known amount of product. The
weight reading should increase to match.

8. Press the right arrow twice on the EI-1000 to exit the menus and return to
the gross weight reading. On the EI-2000 use the left SELECT.

An example using water in a 200 gallon tank:

Enter cal mode. Pump as much water out as possible. Note the gross weight
should be dropping. For this example five gallons were left in the tank.

Zero the scale. Add 20 gallons. The weight reading should rise.

Water is 8.3454 pounds per gallon, so 20 Gallons x 8.3454 = 166.9 pounds.

Set the instrument to read as close to 166.9 as possible. Then exit the cal mode.

After adding 10 more gallons there reading would be 205.4 if there are no
mechanical problems.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

If the tank can’t be emptied now use this procedure. The tank must be
pumped down later to set the true zero.

1. Enter the calibration mode.

EI-1000: Press and hold [SELECT] + [RIGHT ARROW] for greater than three seconds.

EI-2000: Press and hold [LEFT SELECT] + [RIGHT SELECT] for greater than three seconds.

2. The display will show “CFG” (EI1000) or “SEL CFG” (EI2000) Use the up
arrow to change “CFG” to “CAL 1” (1000) or “CAL” (2000). Press SELECT
(1000) or the right SELECT (2000). The display will show the gross weight
with the GROSS light flashing.

3. Press the ZERO pushbutton to zero the instrument. On the EI-2000 use
the ZERO button on the side you are calibrating. NEVER use the arrow
keys to zero the scale. If you do so by accident, unplug the power to the
EI before exiting the calibration mode. This will prevent the zero from
being saved.

4. Check the level in the tank to make sure it won’t overflow when the
desired amount of product is added.

5. Add a known amount of product (at least 10% of the tank’s capacity) to
calibrate. The weight reading should rise while the product is being added.
If it doesn’t, stop! Further troubleshooting is needed.

6. The instrument should show a positive reading. Use the up or down
arrows to set the correct gross weight. On the EI-2000 use the arrows on
the side you are calibrating.

7. To verify the calibration, add another known amount of product. The
weight reading should increase to match.

8. Press the right arrow twice on the EI-1000 to exit the menus and return to
the gross weight reading. On the EI-2000 use the left SELECT.

9. The scale is calibrated at this point but the zero is not correct. Let the take
drain as low as possible through normal usage. It doesn’t matter if this
takes a few days. The weight reading will go negative but still track
properly. Don’t let any pumps run dry if this will cause damage!

10. When the product in the tank is at it’s lowest point, repeat steps 1,2,3 and
7 above to set the zero.

Another example using water in a 200 gallon tank that can’t be emptied:

Enter cal mode and zero the scale. Add 20 gallons. The weight reading should
rise.

20 Gallons x 8.3454 lbs/gal = 166.9 pounds.

Set the instrument to read as close to 166.9 as possible. Then exit the cal mode.

After adding 10 more gallons there reading would be 205.4 if there are no
mechanical problems.

EI-1000 & 2000: Setup, Calibration and Troubleshooting.

Page 18 of 19

Note that the total amount in the tank is unknown at this point. As the 30 gallons
that were added are used the weight reading will drop to zero, then go negative.
When the water is at it’s lowest level, zero the scale.

Recommended: After correct operation is verified, use the diagnostic mode to
write down the values of parameters 1.o, 1.c, 2.o, 2.c. These store the calibration
information. If the calibration or zero is altered these numbers can be reentered
to restore it.

PUSHBUTTONS

The EI-2000 has a set of pushbuttons for each of the two channels, and the EI-1000 has one
set of pushbuttons that control up to four channels (scale bases). The pushbutton functions
listed below describe their typical uses. However, when applicable, the pushbutton(s) may be
used for other functions, which is documented in this manual.

DISPLAYS

EI-2000

PUSHBUTTONS

The main operating mode of the meter is, of course, viewing the weight on the scale(s)
connected to each channel. One can select, via the appropriate SELECT pushbutton, several
weight values; they are as follows:

Gross weight

This is the total weight on the scale, which includes the weight
of the container (e.g., cylinder, tank, or barrel) and the weight of
the product.

Tare weight

This is the weight of the container (e.g., cylinder, tank, or
barrel).

Remaining weight (a.k.a. net weight)

This is the weight of the product (e.g., Chlorine) that
the container holds.

Used weight

This is the weight of the amount used since the scale was last zeroed, which is done by
either “starting” the channel (operating modes 2, 3, and 4) or pressing the ZERO pushbutton
while viewing this display. The EI-2000 display will alternate between a “USEd” message and
the actual used weight value. This value increases with decreasing weight on the scale since
it represents the amount of product used so far.

POUND (lb) AND KILOGRAM (kg) UNITS OPERATION

The EI-1000 and EI-2000 meters may operate using lb or kg units. DIP switch S1-3 selects
the desired unit. If one wishes to switch to the other unit, simply flip the switch to the opposite
setting; no recalibration is necessary. It is necessary to select the proper S1-3 switch setting
so the unit selection works properly (i.e., do not calibrate the scale in kg if the S1-3 switch is
set to lbs). Also, all parameters that were set using the previous units are converted to the
equivalent value of the newly selected unit.

EI-1000 CHANNEL/SCALE BASE SELECTION

If more than one channel is enabled, the RIGHT ARROW pushbutton selects which channel
currently being displayed. Note: The first press of the RIGHT ARROW pushbutton displays,
for one-second, the selected channel (CH x), and the subsequent presses change the
channel.

OPERATING MODES

The EI-1000 & EI-2000 meters have five operating modes to simplify user interactions with
the meter. The descriptions below will reference the set of pushbuttons for the left or right
(CH1 or CH2) channel on the EI-2000 or the set of pushbuttons on the EI-1000 that control
all, up to four, scales. Configuration parameter P001 selects which operating mode, 1 thru 5,
is enabled for all scales.

MODE 1: FULLY MANUAL MODE

Typical application: drum scales, bin and hopper scales - Remaining, tare, & gross weights
are displayable.

1. An empty scale should read zero. If it does not, press the ZERO pushbutton. If
“no 0” is displayed, access the calibration mode to zero the scale.

2. Place container on the scale.

3. Press the SELECT pushbutton to go to the tare weight.

4. If necessary, adjust the tare weight value via the arrow pushbuttons.

5. Press the SELECT pushbutton to go to the remaining weight.

MODE 2: ADJUSTABLE REMAINING

Typical application: drum scales - Remaining & gross weights are displayable.

1. An empty scale should read zero. If it does not, press the ZERO pushbutton. If
“no 0” is displayed, access the calibration mode to zero the scale.

2. Place container with product on the scale.

3. Instrument will show the REMAINING weight and will flash the tare LED.

4. Use the UP and DOWN arrow pushbuttons to adjust the remaining weight
displayed.

5. Press the SELECT pushbutton, the tare LED will stop flashing.

If you need to adjust the REMAINING weight again, press and hold either the UP or DOWN
arrow pushbutton for 3 seconds, the tare LED will start to flash and the remaining weight will
now be adjustable. Press the SELECT pushbutton when finished.

MODE 3: AUTOMATIC OPERATION

Typical application: full cylinders/tanks - Remaining and gross weights are displayable.

1. An empty scale should read zero. If it does not, press the ZERO pushbutton. If
“no 0” is displayed, access the calibration mode to zero the scale.

2. Place a full container on the scale; the Gross LED will flash.

3. Adjust gross weight by using the UP and DOWN arrow pushbuttons.

4. Press the SELECT pushbutton; the tare weight will be automatically calculated
and stored in memory. The preset “START” value (configuration parameter
Px17) of remaining chlorine weight will now be displayed, and the REMAIN LED
is illuminated.

If the REMAINING weight must be adjusted again, one should press and hold either the UP
or DOWN arrow pushbutton for 3 seconds. The tare LED will start to flash and the remaining
weight will now be adjustable. Press the SELECT pushbutton when finished.

MODE 4: ADJUSTABLE TARE

Typical application: partially used chlorine cylinders - Remaining, tare, & gross weights are
displayable.

1. An empty scale should read zero. If it does not, press the ZERO pushbutton. If
“no 0” is displayed, access the calibration mode to zero the scale.

2. Place a full container on the scale.

3. The Gross LED will flash.

4. Adjust gross weight by using the UP and DOWN arrow pushbuttons.

5. Press SELECT, tare will now be displayed (tare LED should be illuminated).

6. Adjust tare, as required, by using the UP and DOWN arrow pushbuttons.

7. Press SELECT, the remaining weight will now be displayed (REMAIN LED
should be illuminated).

MODE 5: USER-ADJUSTABLE REMAINING

Typical application: chlorine gas cylinders. - Remaining and gross weights are displayable.

1. An empty scale should read zero. If it does not, press the ZERO pushbutton. If
“no 0” is displayed, access the calibration mode to zero the scale.

2. Place a full container on the scale.

3. “REMAIN” LED will light.

4. Use the UP and DOWN ARROW pushbuttons to adjust the remaining weight
displayed.

5. The SELECT pushbutton will toggle display between gross and remaining
weights.

Note: This operating mode mimics the standard modes of other manufacturer’s scales. The
ability to display the true “Gross” weight value allows the operator to verify the remaining
value displayed; overfilled cylinders can be detected.

REMAINING_WEIGHT = GROSS_WEIGHT - CYLINDER_WEIGHT - VALVE_WEIGHT.

!! CAUTION !!

IN MODES 2 & 5, THE DISPLAYED “REMAINING” VALUE CAN BE EASILY CHANGED TO GIVE AN ERRONEOUS
READING. BEFORE REMOVING THE VALVE FROM AN ”EMPTY” CYLINDER OR OPENING THE VALVE ON A FULL
CYLINDER, ALWAYS VERIFY THE REMAINING VALUE WITH THE GROSS WEIGHT.

MODE 6: GROSS ONLY MODE

Typical application: Varies
The only weight displayed is gross. One calibrates by manually enabling this calibration
mode.

HIDDEN PUSHBUTTON FUNCTIONS

Scale gross weight recalibration/restart:

When a cylinder or tank is on the scale (above the weight threshold in modes 2-5, see
parameters P116, P216, etc.), press and hold the SELECT pushbutton until the gross LED is
starts to flash. At this time, the user may now use the UP and DOWN arrow pushbuttons to
adjust the gross scale calibration. When satisfied that the weight is correct, press the
SELECT pushbutton to restart the scale. Depending on the operating mode, a new start
remaining weight will be calculated and the used display will be zeroed.

Tare lock:

If this function is enabled (parameter P030), operating modes that display the tare weight
(modes 1 and 4), will not allow adjustment of the tare weight without first holding the UP or
DOWN arrow pushbutton for three seconds. To store the new tare, press the SELECT
pushbutton to display the remaining weight.

Front Panel Configuration/Calibration/Diagnostic Access (FPA)

Scale Selection (cont.)

To load default scale calibration for the scale selected above, press and hold the RIGHT
SELECT (EI-2000)/SELECT (EI-1000) pushbutton until LOAD YES/NO (Y/n) appears. Press
the (RIGHT) UP ARROW to select yes or no (Y/n) and then press the (RIGHT) SELECT
again to enter your choice. This also must be done for channels two through four (if enabled).

P110 Full-scale (10 to 9900)

This sets the full-scale in the units selected by the lb/kg switch, S1-3. This is used to limit set
points and other parameters that are entered using lb or kg weighing units.

P111 Resolution (0.0001 to 500)

This sets the weight division for the unit selected by the lb/kg switch. The choices for the EI­2000 are 0.1, 0.2, 0.5, 1, 2, and 5. The choices for the EI-1000, since it has a six digit display,
are extended to the range of 0.0001 to 500.

P112 Average (1, 2, 4, 8, 12, 16, or 20)

This parameter sets the number of scale weight acquisitions before the display is updated to
the weight on the scale. Higher numbers yield a more stable less responsive meter reading.

P113 Auto-zero (off, 0.01, 0.02, 0.03, 0.05, 0.1, 0.2, 0.3, 0.5, 1, 2)

Auto zero is used to automatically zero the meter (same as pressing the zero pushbutton).
This setting controls how much of scale range in percentage will automatically be zeroed
when the load (e.g., container, tank or cylinder) is remove from the scale. All negative values
are zeroed regardless of this setting unless it is set to off.
Example: If full-scale is 300lbs and auto-zero is set to 0.5 (%), the weight must be below

1.5lbs for the meter to automatically zero the scale.

P114 Push to Zero/Auto-zero PTZ/AZ maximum range (OFF, 2, 5, 10, 20, 50, or ALL).

When the load is removed from the scale, in an ideal world, the weight returns to zero.
However, usually the meter reading is above zero. If the auto-zero is enabled (Px13) and the
weight is within its range, the meter will automatically zero the weight. If it’s not, the user
should press the zero pushbutton for the selected channel.

The PTZ/AZ parameter, set in percentage of full-scale, selects the maximum amount of
weight that is permitted to be zeroed either automatically or by pressing the zero pushbutton.

Example: If full-scale is 300lbs and PTZ/AZ is set to 2 (%), the weight must be below 6 lbs for

the meter to allow the automatic zero (AZ), if enabled, to zero the scale or the ability to zero
the scale via the ZERO pushbutton. Note: If the threshold (Px16) weight is exceeded, the
automatic zero and pushbutton zero are inhibited.

Note: The “ALL” setting allows unlimited zeroing ability, which is not a recommended setting
since the scale load-cell may be shifting too much.

The off setting was added to firmware version 6.21. The user must enable calibration to zero
the scale.

P116 Threshold (0 to full-scale)

This applies to operating modes 2 through 5. This sets the point (in lbs or kgs) that the meter
will enable, depending on the operating mode, switching to remaining or enabling adjustment
of the gross weight calibration or remaining weight.

P117 Start (0 to full-scale)

This parameter applies to operating modes 3 & 4. This is the value of the remaining weight
(in lbs or kgs) when the scale channel is “started.” See the “operating modes” section of this
manual.

P2xx, P3xx & P4xx

Parameters P2xx, P3xx and P4xx are identical to the P1xx set but control scale bases two
through four, respectively. Inactive channel parameters are hidden. If the EI-2000-EXP is not
installed, P3xx and P4xx parameters are not available.

P500 Set point A mode selection

Set points are disabled

Off

Lo(w)-level

Hi level

Low-level, remaining weight set point

High-level, remaining weight set-point
The set points have a 1% hysteresis (based on the full-scale) and an activation delay of three
seconds. For example, if the full-scale is 300lbs, the set point is 10lbs, and the low-level set
point mode is selected, the relay is energized when the remaining weight is equal to or below
10lbs for three seconds. The relay is de-energized when the remaining weight goes above
13lbs. If the high-level set point is enabled, the relay is also energized at 10lbs after three
seconds, but it’s de-energized at 7lbs.

P501 Set point B mode selection

This parameter is used if either the EI-2000-EXP or EI-2000-I/O board is installed or if the EI­1000 meter has only one channel enabled. The selections are identical to the P500
parameter.

P510 Set point A value for channel 1
P511 Set point B value for channel 1
P520 Set point A value for channel 2
P521 Set point B value for channel 2
P530 Set point A value for channel 3
P531 Set point B value for channel 3
P540 Set point A value for channel 4
P541 Set point B value for channel 4

These are the set point values for each channel; they are set in lb or kg units, depending on
the unit selection switch, S1-3.

EI-2000S-CPU

The diagram to the right shows an example
of relay contact wiring.

The relay specifications are mechanical,
3A, & 250VAC/250VDC maximum.

TB2 contacts are “dry” (potential free), so
the load power supply is external, see the
example circuit to the right.

If the load is inductive, add a snubber (RC)

circuit across the relay contact terminals to
greatly extend the life of the relay contacts.
One can also connect the snubber across
the load in lieu of the contacts.

P600 Analog output type selection

Analog output: rE (remaining weight), Gr (gross weight) , Gt
(gross total – sum of all active channels), and nt (remaining total
– sum of all active channels). This selects the weight that is
transmitted via the 4-20mA analog outputs.

P610 Analog output 20mA (full-scale) weight for channel 1
P620 Analog output 20mA (full-scale) weight for channel 2
P630 Analog output 20mA (full-scale) weight for channel 3
P640 Analog output 20mA (full-scale) weight for channel 4

A 20mA analog signal is transmitted when the weight is equal to
the value set by the above parameter. A current of 4mA is
transmitted when the weight, selected by P600, is equal or less
than zero. The analog outputs do not go below 4mA or above
20mA under normal operation.

P650: 4-20mA clip: NO will allow the mA output to proportionally

fall below 4mA (0 lb/kg) or rise above 20mA until hardware limits
are reached. YES will limit the analog output to the 4-20mA
range.

WEIGHT SUMMATION FUNCTION

(FIRMWARE VERSION 6.40 AND ABOVE)

The EI-2000 has the ability to sum all of the scales connected to the meter (up to two) as well
as two additional scales, which are connected to another EI-2000 (secondary) meter.

P990 SUM CH (sum all channels)

YES: Sum all active scale inputs. Net or gross total is selectable from the front panel.
NO: Scale inputs are not summed.

P991 SUM SEL (sum selection)

rE: Remaining weights are summed (most applications).
Gr: Gross weights are summed.

P992 SUM EXT (sum external EI-2000).

YES: Sum all active scales. Up to four scales are summed and displayed.
NO: External (secondary) EI-2000 is not present.

Note: The sum cannot be viewed on the secondary meter.

VIEWING THE SUMMED WEIGHT

To view the summed weight, press SELECT until “Gr t” or “rE t” is displayed. The display will

alternate between the label (Gr t/nE t) and the weight. In some scale modes, the total display
is only viewable when there is a load on the scale.

PRIMARY/SECONDARY EI-2000 CONNECTIONS & CONFIGURATION

Primary meter: P990=YES, P991=don’t care, P992=YES
Secondary meter: P990=NO

The following parameters must be set the same in both meters:

P700=BAS, P701=9600, P702=8, P703=1, P704=NONE, P705=don’t care

Note: If only one channel is enabled on the primary meter, the total weight is always displayed on the
right display of the primary meter. This is useful when three channels are enabled (one on the primary
meter and two on the secondary meter).

Connections are below (connect C to C, R to T, & T to R):

MISCELLANEOUS PARAMETERS

P999 Front panel cal/cfg access (FPA)

Enable or disable (ON or OFF) this function; see the “Front Panel
Configuration/Calibration/Diagnostic Access (FPA)” section of this manual.

ANALOG OUTPUTS

The EI’ series furnishes an analog 4-20mA (milliamp) signal for transmission to a remote
system such as a SCADA or RTU for each channel (up to four). From the factory, the
calibration is within 1.5% of 4mA and 1.5% of 20mA or better. Therefore, it is recommended
that one performs a 4-20mA calibration adjustment for each channel if a more accurate
matching between the meter and user system is required.

To access the analog output calibration/test mode, close S1-2 (S1-1 & S1-4 are open) or use
the FPA sequence. These parameters are used to calibrate the 4 - 20mA analog output
points for each channel. See the table below for push-button functionality. NOTE: Left zero,
left select, right zero & right select have no function in Analog Output Configuration.

EI-2000

Left, up and down arrow pushbuttons Select a parameter
Right, up and down arrow pushbuttons Alter the value of the parameter

EI-1000

UP/DOWN arrows select a parameter.
To alter the value of a parameter, press the SELECT pushbutton. Use the
UP/DOWN ARROWS pushbuttons to set the desired value and then press the
SELECT pushbutton when finished.

PARAMETER EI-1000: Ao.tESt
PARAMETER EI-2000: Ao t xx.xx

This parameter tests both Digital to Analog Converters using ten,
linear 1.6mA steps from 4.00 mA to 20.00 mA.

The analog outputs are active (self powered). Therefore, the load must be passive
(voltage/potential free) so no damage occurs to the EI-2000S-CPU or the user’s system. The
“R LOAD” resistance can range from 0 to 510 ohms. When one is calibrating the analog
outputs, the “R LOAD” represents the DMM or 4-20mA calibrator device.

Note: The –L & -R (terminals 1 & 3) are connected and this must be taken into
consideration when connecting the load to the analog outputs. Refer to schematic
above.

ANALOG 4mA and 20mA POINT ADJUSTMENT PARAMETERS

Each analog output is calibrated to 4mA and 20mA points, so each of the up to four analog
outputs has a 4mA and 20mA point setting – see the parameters below:

EI-1000

ANALOG OUTPUT 4.00 mA (ZERO) ADJUSTMENT: EI-1000

PARAMETER EI-1000: Ao.x (x = 1,2,3, or 4) Press

Set the left 4.00 mA analog output point using the up & down arrow pushbuttons. The display
will not show any indication that the left analog output is changing which is why one should
have a "mA" meter (i.e., DMM) connected to the appropriate output. The mA output range is
approximately 4.0 mA +/- 1.0 mA.

ANALOG OUTPUT 20.00 mA (SPAN) ADJUSTMENT: EI-1000

PARAMETER EI-1000: Ao.x (x = 1,2,3, or 4)

Set the left 20.00 mA analog output point using the right up & down arrow pushbuttons. The
display will not show any indication that the left analog output is changing which is why one
should have a "mA" meter (i.e. DMM) connected to J3-1 & J3-2. The mA output range is
approximately 20.0 mA +/- 1.0 mA.

EI-2000

ANALOG OUTPUT 4.00 mA (ZERO) ADJUSTMENT: EI-2000

PARAMETER EI-2000: "AO x" " 4.00" (x = 1,2,3, or 4)

Set the left 4.00 mA analog output point using the right up & down arrow pushbuttons. The
display will not show any indication that the left analog output is changing which is why one
should have a "mA" meter (i.e., DMM) connected to the appropriate output. The mA output
range is approximately 4.0 mA +/- 1.0 mA.

ANALOG OUTPUT 20.00 mA (SPAN) ADJUSTMENT: EI-2000

PARAMETER EI-2000: "AO x" "20.00" (x = 1,2,3, or 4)

Set the left 20.00 mA analog output point using the right up & down arrow pushbuttons. The
display will not show any indication that the left analog output is changing which is why one
should have a "mA" meter (i.e. DMM) connected to J3-1 & J3-2. The mA output range is
approximately 20.0 mA +/- 1.0 mA.

DIAGNOSTICS

The diagnostic mode is an advanced mode that one can use to restore scale calibration and
read the raw scale output in mV/V (millivolt per volt). One enters the diagnostic mode by
either the DIP switches (S1-1 & 2 = ON & S1-4=OFF) or by the front panel access method.

1.U, 2.U, 3.U, or 4.U: Scale mV/V signal

This displays the scale mV/V signal (terminals +S & -S) for each channel. The normal range
for an empty scale is from -0.1mV/V to 0.1mV/V. However, if there is a vessel, tank, etc. (with
no product) attached or sitting on the scale, this value can be higher than 0.1mV/V. The
nominal range with product on the scale is from 0.2mV/V to 3mV/V.

A DMM measuring the actual mV at the signal terminals would read about five times the
value read here (e.g., a 1mV/V “1.U” display would show as 5mV on a DMM).

DIAGNOSTIC CALIBRATION READ/ENTRY

The following parameters allow one to read and re-enter calibration zero and span. These
parameters are used for approximate calibration if one does not have test weights or the
ability to remove the weight from the scale. Entering these values, if calculated and entered
correctly, will yield a 0.25% or better calibration for each channel.

In order to use these parameters, the scale mV/V at a specific lb/kg weight (e.g., 3mV/V at
4000lbs) must be known - this is the “(scale) FULL SCALE” entry that’s written on the EI’
routing sheet.

1.o, 2.o, 3.o, & 4.o: Scale calibration dead-zero (one for each active channel)

The scale mV/V dead-zero value represents the weight of the platform and, possibly, a fixed
tank. NOTE: This value does not include the weight a removable cylinder or tank. Any
PTZ/AZ values are not added to the zero value displayed.

[FS mV/V]

DEAD ZERO = ------------------------- x [Assumed dead weight WT (lb/kg)]

[FS WT (lb/kg)]

Example: If the scale full-scale is 3mV/V @ 4000lbs and the assumed dead weight is
500lbs, the value one would enter into the dead zero value parameter is 0.3750.

1.c, 2.c, 3.c, & 4.c: Scale calibration span (one for each active channel)

Scale calibration value: This is the load that is typically removable that includes the weight of
the product and container combined. Use the formula below to calculate an approximate
calibration factor that’s entered into this parameter. To shift the decimal point, press the
RIGHT ARROW pushbutton on the EI-1000 or the RIGHT SELECT pushbutton on the EI-

2000.

[FS WT (lb only!)]
CAL = -------------------------

[FS mV/V]

Note: If the full scale weight is in kilograms (kg), multiply the weight by 2.2046 and
then divide it by the full scale mV/V value.

Example: If the scale full-scale
is 3mV/V @ 4000lbs, the CAL
value entered is 1333.3.

POWER-UP FUNCTIONS

Power-up functions are activated by, first, powering down the meter, pressing the desired
pushbutton combination, and restoring power to the meter.

Restore all parameters and calibration to factory default settings.

This function erases all non-volatile memory and restores the instrument to a factory default
setup. The 4-20mA analog outputs, scale inputs and ALL parameters must be checked and

changed to proper values to match the scale. Recalibration of the scale is required.

EI-1000: [DOWN ARROW] + [SELECT] + [UP ARROW]
EI-2000: [LEFT UP ARROW] + [LEFT SELECT] + [RIGHT SELECT]

Load typical settings for the selected scales.

This function will load a default scale calibration and setup scale parameters depending on
the P100, P200, P300 and P400 selections. The 4-20mA analog output calibration (not full
scale) is not altered, but one should check the P6xx parameters to insure that they are set to

their proper settings. Recalibration of the scale is required.

EI-1000: [DOWN ARROW] + [UP ARROW]
EI-2000: [LEFT SELECT] + [RIGHT SELECT]

Display test

This function illuminates all 7-segment LED displays and indicator (e.g., gross & remaining)
LEDs.

EI-1000: [ZERO] + [DOWN ARROW] Exit: [RIGHT ARROW]
EI-2000: [LEFT ZERO] + [RIGHT ZERO] Exit: [LEFT UP ARROW]

I/O Test mode

This function cycles the 4-20mA outputs and relays. Also, the keypad pushbuttons, DIP
switches and remote input (TB6, IN) functionality can be verified, as well.

EI-1000: [DOWN ARROW] + [RIGHT ARROW] Exit: [ZERO] + [DOWN ARROW]
EI-2000: [RIGHT SELECT] + [RIGHT UP ARROW] Exit: [RIGHT ZERO] + [RIGHT DOWN ARROW]

Read one or more registers using command 0x03 Registers (0x900-0x917, 24 registers) can also be read by the report slave ID command (0x11).

Write one register using command 0x06. *Note: To store the new value in EEPROM (non-volatile), send the 0x0f00 command.

Write one or more registers using command 0x10. Registers are big-endian formatted (that is, the MSB is the lower address)

To calculate the REGISTER 4xxxx address, add 40001 to the decimal value of the ADDRESS (e,g., Address 0x1000 (4096 decimal) is register 44097).

" V6.00"
" lb"

Value is from 1 to 4, which is the number of channels that are enabled.

" kg"

MODBUS REGISTER LIST (FIRMWARE VERSION 6.xx) SEE Modbus_Application_Protocol_V1_1b.pdf FOR PROTOCOL FORMAT REVISED: 2015-09-18

This reads a 66.6ms/tick counter, which has the range from 0 to 0xffff.

Write 0x0001 to this reg to store data in the EEPROM

Gross weight on the scale

Net weight on the scale, which is gross weight minus the tare weight.

*Tare weight, which is the tank, cylindar, etc.

Used weight, which the starting weight minus the gross weight. However, it is a positive
number (the sign is flipped).
