PUSHBUTTONS
The EI-4000 has a set of four pushbuttons. The functions are
typically indicated by the bottom line on the LCD (SEL CHAN
ZRO MNU). Some displays have a hidden function that is
documented where applicable in this manual. The push buttons
from left to right are PB1 (left-most), PB2, PB3 and PB4 (right-
most).
WEIGHT DISPLAY SCREENS
1:GR 0.0 lb
SEL SCL ZERO MNU
When the meter is powered, the main weight screen is displayed. One can select, via the
appropriate select (SEL) pushbutton, several weight values; they are shown below. However,
if the meter is operating in modes two through five, the weight on the scale must be above
the threshold (explained later) in order to select tare, remaining and used weight displays.
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. The “GR” text is short for gross weight. The gross weight
can be zeroed if ZERO is displayed above the PB3 pushbutton (see the display at the top of
this page).
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. The “REM” text is short for remaining (net) weight.
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. This value increases with decreasing weight on the scale since it
represents the amount of product used so far.
The gross, remaining and tare formula is as follows:
[REMAINING WEIGHT] = [GROSS WEIGHT] – [TARE WEIGHT]

If two or more channels are enabled, the CHAN (channel)
pushbutton is available to select another channel. If less than four
channels are enabled (i.e., two or three), CH4 is replaced by an
ESC (escape) pushbutton so one can return to the main operating screen. If no selection is
made after three seconds, the screen returns to the main weight display.

POUND (lb) AND KILOGRAM (kg) UNITS OPERATION
The EI-4000 meter 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.
OPERATING MODES
1:GR 136.0 kg
SEL SCL MNU
The EI-4000 meter has five operating modes to simplify user interactions with the meter.
Configuration parameter P001 selects which operating mode, 1 thru 5, is enabled for all scale
channels.
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 ZRO (ZERO)
pushbutton. If the ZRO pushbutton is not 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 ZRO (ZERO)
pushbutton. If the ZRO pushbutton is not 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 REM text.
4. Use the UP and DOWN arrow pushbuttons to adjust the remaining weight
displayed.
5. Press the ENT pushbutton after making any adjustments; the user will no longer
be able to adjust the remaining weight.
If you need to adjust the REMAINING weight again, press and hold PB3 for 3 seconds, the
REM text will start to flash and the remaining weight will now be adjustable. Press the ENT
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 ZRO (ZERO)
pushbutton. If the ZRO pushbutton is not displayed, access the calibration
mode to zero the scale.
2. Place a full container on the scale; the GR text will flash.
3. Adjust gross weight to the correct value by using the UP and DOWN arrow
pushbuttons.
4. Press the ENT 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.
To enter a new tare weight if the remaining value displayed is incorrect, press and hold PB3
for 3 seconds. The display will change to the TARE weight (TARE flashes). Adjust the tare
weight to the correct value and then press ENT when finished (REM = GROSS – TARE). The
remaining weight will again be displayed.
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 ZRO (ZERO)
pushbutton. If the ZRO pushbutton is not displayed, access the calibration
mode to zero the scale.
2. Place a full container on the scale.
3. The “GR” text will flash.
4. Adjust gross weight to the correct value by using the UP and DOWN arrow
pushbuttons.
5. Press the ENT pushbutton.
6. The tare will now be displayed as indicated by the flashing “TR” text.
7. Adjust tare, as required, by using the UP and DOWN arrow pushbuttons.
8. Press ENT, the remaining weight will now be displayed.
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 ZRO (ZERO)
pushbutton. If the ZRO pushbutton is not 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.
!! 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 REMAINING VALUE WITH THE GROSS WEIGHT.
REMAINING_WEIGHT = GROSS_WEIGHT - CYLINDER_WEIGHT - VALVE_WEIGHT.
GROSS WEIGHT HIDDEN PUSHBUTTON FUNCTION
Scale gross weight recalibration/restart:
All modes have a hidden gross calibration screen.
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 PB3 until the “GR” starts to flash. At this time,
the user may now use the UP and DOWN pushbuttons to adjust the gross scale calibration.
When satisfied that the weight is correct, press the ENT pushbutton to save the new gross
weight value.
EXTENDED MAIN SCREEN DISPLAYS (rate, daily use, totalizer and time until empty)
RATE
The rate is the change in weight per unit time, which is selectable
by parameter P900.
DAILY
The daily usage displayed is the last 24-hours of product use.
This screen as well as the daily log screens are enabled by
parameter P920.
TTL
The totalizer display is the amount of product that is removed
from the scale. The totalizer can be reset by pressing the RST pushbutton. The totalizer
value is retained when the EI-4000 is not powered for, at least, seven days.
EMPTY
The time until empty display displays the time until the scale is
empty.
HR: “dd hh:mm” format (days, hours and minutes)
DAYS: Displays a days until empty value in days to the
hundredths resolution (e.g., 1.50 is 1-day & 12-hours).

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. This parameter is
available only when the scale selection parameter, P100, is set to “user.”
P111 Resolution (0.0001 to 500)
This sets the weight division for the unit selected by the lb/kg
switch. The choices are 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, and 5.
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 removed 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 (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 ZRO (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 ZRO pushbutton. Note: If the threshold (Px16) weight is exceeded
(operating modes 2-5), 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.

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

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 or greater for
3-seconds, but it’s de-energized at 7lbs.

•The diagram below shows an example of the EI-2000S-CPU (EI-4000) 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.
•The relays on the EI-2000-CPU (TB2, CH1 & CH2) and EI-2000-EXP (TB10, CH3 & CH4) are not used
for the SP1 and SP2 set points when the EI-2000-IO is installed.
•The LCD1602-EI board furnishes two, ½A, 115VAC/30VDC relays (K11 & K12).

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
parameters. A current of 4mA is transmitted when the weight, selected by P600, is equal to 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 4mA to 20mA range.

as four additional scales, which are connected to another EI-4000.
NOTE: The parameters below are only set on the master indicator. The slave indicator
must have P990 set to NO. The sum cannot be viewed on the slave indicator.
P990 SUM CH (sum all channels)
YES: Sum all active scale inputs.
NO: Scale inputs are not summed.
P991 SUM SEL (sum selection)
RE: Remaining weights are summed.
Gr: Gross weights are summed.
P992 SUM EXT (sum external EI-4000).

CALIBRATION MENU
The calibration menu is accessed by pressing the MNU
pushbutton (main screen), pressing CAL, and then entering the
correct password (if the password is enabled). The calibration
menu choices are as follows:
SCL – Calibrate the scale
OUT – Calibrate/test the analog outputs
DIAG – View the raw mV/V scale values and view/enter the zero and span values.
ESC – Exit to then main menu.
CALIBRATING THE SCALES (CALIBRATION MENU: SCL)
The user can calibrate the scale using the set of screens shown below. All operational modes
(one through five) can calibrate the scale using the hidden gross adjustment function, but
these set of screens allow the user to zero any amount of weight; the main-screen gross zero
pushbutton (ZRO) has a limit on the amount of weight that can be zeroed.
While in the calibration menu, press SCL. If more than one
channel is enabled, the calibrate scale select screen is displayed.
If the user doesn’t select a scale within five seconds, the display
returns to the calibration menu. If scale four is not enabled, the CH4 pushbutton (PB4) is
reassigned as an escape (ESC) back to the calibration menu.
After a channel is selected for calibration, the zero/span
calibration screen is displayed. The “GR” text flashes to indicate
that the user can adjust the displayed weight. The user can zero
any weight on the scale by pressing the ZERO pushbutton.
The user should remove all weight from the scale before zeroing the scale.
The user should now place a known weight on the scale, allow
some time for the weight reading to stabilize, and then press the
SPAN pushbutton. The weight adjustment (span) screen will be
displayed. Use the UP and DOWN arrow pushbuttons to set to correct weight. Note: The
weight display is dynamic, so adding or removing weight from the scale will change the
displayed value and this includes a user-adjusted weight value. After the correct weight has
been set, press the ENT pushbutton to enter the new weight value.
The new scale calibration values are stored in EEPROM permanently when the user presses
the ESC pushbutton in the ZERO/SPAN scale calibration screen.

ANALOG OUTPUTS (CALIBRATION MENU: OUT)
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 0.5% of 4mA and 0.5% 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, press MNU, CAL, enter password (see
password section) if enabled, and then press the OUT pushbutton.
ANALOG OUTPUT TEST
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-4000 (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:
ANALOG OUTPUT 4.00 mA (ZERO) ADJUSTMENT
Press the ADJ pushbutton, and then set the left 4.00 mA analog
output point using the UP and DOWN 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. Press ENT
when finished adjusting the 4 mA output point.
ANALOG OUTPUT 20.00 mA (SPAN) ADJUSTMENT
Press the ADJ pushbutton, set the left 20.00 mA analog output
point using the UP and DOWN 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 20.0 mA +/- 1.0 mA. Press ENT when finished
adjusting the 20 mA output point.

DIAGNOSTICS (CALIBRATION MENU: DIAG)
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).
Scale mV/V signal (one for each active channel)
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
0.5mV/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 SCL1 screen 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 an 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.
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

values are not added to the zero value displayed. Press ADJ to adjust this value.

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 DP pushbutton.
