1. GENERAL DESCRIPTION
The Toledo 8510-2001 and 8510-2011 are panel mount digital indicators, intended for use with Toledo
DigiTOL ® Digital Load Cell Scale Bases or an Analog Load Cell Scale Bases or an Analog Load Cell
Scale Base using up to 4-350 ohm analog load cells. Weight and setup information is displayed on a 6digit 7-segment vacuum fluorescent display. Setup and calibration are performed using softswitches in
a “setup mode”. The setup information is retained in memory if power is removed from the 8510. The
keyboard is a 5-position non-tactile membrane type. Serial RS232 output is provided for the METTLER
TOLEDO 8806, 8860, 8840, 8842, and 8843 printers, or to a host device. Remote print, tare, clear, and
zero commands can be input from a host using certain ASCII characters through the RS232 serial port.
Options include an Analog Output kit, a BCD kit, and a Setpoint kit.
2. SPECIFICATIONS
2.1 ELECTRICAL
The Model 8510 Panel Mount Indicator does not have an ON/OFF Switch and is connected directly to the
power source with a line cord. Input power is approximately 10 watts. The incoming power is internally
fused by F1 on the Power supply PCB. Configurations are available for 120 VAC/60 Hz and 220/240
VAC/50 Hz. The Model 8510 Panel Mount Indicator is designed to operate at the following voltage
ranges:
FACTORY
NUMBER
8510-2001 120 VAC 100 TO 130 VAC .15A 59 TO 61 HZ
8510-2011 220/240 VAC 187 TO 264 VAC .08A 49 TO 51 HZ
Being micro-computer based, the Model 8510 is designed, manufactured, and tested to withstand certain
levels of voltage spikes, AC power sags and surges, and RFI (radio frequency interference). The Model
8510 requires AC power that is free of power noise, sags, and surges beyond the tested parameters and
within the rated voltage range.
The AC power must not be “shared with” equipment that is known to generate AC power noise in the
form of line spikes, voltage sags, or voltage surges. The term “shared with” means that the 8510 AC
power is connected on the same line or distribution box as the noise generating equipment, and that the
8510 does not have a noise isolation type transformer between it and the incoming power that is capable
of blocking the noise being generated.
2.2 OPERATING/STORAGE TEMPERATURE AND HUMIDITY
The Model 8510 will operate in a temperature range between -10 degrees C (14 degrees F) to 45 degrees
C (113 degrees F) with non-condensing relative humidity between 10 to 95%.
2.3 CAPACITY/INCREMENT SELECTION TABLE
Scale capacity and increment size is selected in the set-up mode and is limited to the combinations

TABLE 1 - CAPACITY/INCREMENT SELECTIONS FOR 8510-20X1
2.4 ANALOG BUILD PRELIMINARY CALCULATIONS
Before connecting the 8510 to an analog understructure, it must be determined if the load cell(s) are of a
size that will work correctly with the instrument and platform. If the installation is a standard build,
proceed with the installation. However, if the installation is a special build or a conversion of an
existing mechanical scale base, the microvolt per increment rating must be calculated. First calculate
the microvolts per increment, then check with the charts to make sure the proposed load cell(s) are the
correct size.
2.4.1 To find the microvolt per increment build, you must first find:
a) Scale capacity*
b) Increment size*
c) Number of load cells or total lever ratio
d) Capacity of load cell(s)*
e) Cell output rating in mV/V (millivolts per volt of excitation)j
* In lb or kg depending on how the scale is to be calibrated and used.
2.4.2 Next find the total load cell output in millivolts by multiplying the cell output rating* by the 8510
excitation voltage, 12.5 volts.
NOTE: Toledo load cells are 2mV/V. Other types may be 1mV/v, 1.75mV/V, or 3mV/V.
2.4.3 Use the following formula to calculate the microvolt per increment ratio.
Increment Size X Total Load Cell Output (mV) X 1000 Load
Cell Capacity X Number of Cells (or lever ratio)
2.4.4 Divide the scale capacity by the increment size to determine the number of increments to be
programmed.
2.4.5 Refer to Table 2 (2Mv/V Load Cells) or Table 3 (3mV/V Load Cells) for the check to see if the build
is necessary.

Scale Capacity 5000 lb
Increment Size 1 Lb
Number of Cells 4
Capacity of Cell 2000 Lb
Cell Output Rating 2 mV/v
Step 1) Find total load cell output (mV)
2 mV/v X 12.5V = 25 mV
Step 2) Use the formula for finding µV/Inc.
1 lb X 25 mV X 1000
2000 lb X 4 = 3.13 µV/Inc.
Step 3) Divide scale capacity by increment size to determine number of increments to be
programmed.
5000 lb
1 lb = 5000 Increments
Step 4) Check the Microvolt Per Increment Chart Table 2 or 3, to see if this build fits into the 5000
increment range. If it does, this will be a satisfactory build.

2.7 LOAD CELL SPECIFICATIONS
2.7.1 ANALOG LOAD CELLS
The 8510 supplies 12.5 VDC load cell excitation voltage for up to four 350 ohm analog load cells (87.5
ohm max load). Jumper W1 on the Power Supply PCB is used to select either 2mv/v or 3mv/v load cells.
The initial range is adjustable from 0 to 15mV. Span is adjustable from 3 to 25 mV.
2.7.2 DIGITAL LOAD CELLS
A supply of 20 VDC at 180 ma is provided for the METTLER TOLEDO DigiTOL® digital load cell.
2.8 OVERCAPACITY AND UNDER ZERO
Overcapacity is indicated by display blanking and occurs at full capacity plus five (+5) increments.
Weight under zero will be displayed up to the negative out-of-range limit. The negative weight indication
will be preceded by a minus (-) sign. When the negative out-of-range limit is reached, the display will
blank.
2.9 DIGITAL DISPLAY
The display is a green-blue vacuum fluorescent type. It consists of six 0.5” seven-segment digits with
lighted decimal point. Six fluorescent indicators are located below the display to correspond to printed
legends on the display lens, as shown in Figure 1. The display update rate for analog and digital load
cells is 12 updates/second.

2.11 ZERO
2.11.1 AUTO ZERO MAINTENANCE (AZM)
The range of zero maintenance is limited to ± 2% of scale capacity, with the center of the range
determined during calibration. Weight variations which occur at a rate of 0.2 increments per second or
slower will be compensated. AZM can be disabled in the setup mode.
2.11.2 PUSHBUTTON ZERO
A front panel pushbutton provides re-zeroing of the scale over a range of ± 2% of scale capacity. The
ZERO pushbutton must be depressed while the scale is in a no-motion condition and at gross zero.
Pushbutton zero can be disabled in the setup mode.
2.11.3. POWER UP ZERO
When power is first applied to the scale, zero is automatically captured provided the weight is within +
2% of scale capacity, and a no-motion condition exists.
2.11.4 ZERO INDICATOR
The zero increment is ± 0.,5 increment wide. The display’s “zero indicator” is ON whenever the weight is
within ± 0.25 increment of the center of the zero increment.
2.12 TARE
2.12.1 PUSHBUTTON TARE
The TARE pushbutton on the keyboard can be used to tare a weight on the scale platform if the scale is
in a no-motion condition. If the weight is then removed from the scale platform, the Net Weight will be
displayed as a negative value. The NET indicator will be illuminated whenever a tare weight exists in the
Net Storage Register. Pushbutton Tare can be disabled in the setup mode. If the tare operation results
in a six digit negative net weight, the display will alternate between the weight value and a blank display
with a minus sign.
2.12.2 REMOTE TARE
If enabled in setup mode, a remote tare command using ASCII input will tare the weight on the scale
platform, providing the scale is in a no-motion condition. A remote tare clear command from a host will
clear the tare value if the weight has settled to a no-motion condition. See Section 5.4 for details.
2.12.3 MANUAL AND AUTO CLEAR TARE
Tare can be cleared manually by use of the CLEAR pushbutton, or automatically if the weight has settled
to a no-motion condition at a weight greater than 10 increments and returned to less than 0.5 major
increments from zero gross weight.

3.5 POWER REQUIREMENTS
WARNING!
FOR CONTINUED PROTECTION AGAINST SHOCK HAZARD, CONNECT TO
A PROPERLY GROUNDED OUTLET. DO NOT REMOVE THE GROUND
PRONG.
The 8510 requires a properly grounded dedicated AC power line which must not be shared with other
types of electrical equipment which may generate “noise spikes” or “power surges”. The equipment
ground prong on the power cord must not be removed or bypassed using an adapter plug.
No AC voltage should exist between the Neutral and Ground lines. Voltage readings (between Neutral
and Ground) above 0.1 VAC indicate a problem with the ground line, and should be corrected before
connecting the 8510 to the line.
The supplied AC voltage to the 8510 must be within tolerances shown on the chart in Section 2.1, and
transient free. An isolation/regulation type transformer for electronic equipment may be required if these
types of problem conditions exist, and cannot be corrected at the source.
3.6 POWER UP SEQUENCE
On power up, the 8510 will display the following:
[888888] - All segments will momentarily illuminate.
[129123] - The Software Part Number will briefly display.
[L RR] - The Revision Level (RR) of the Software will briefly display. Example: L05 = “E” revision
software)
[xxxxxx] - The weight (x) will display next (or zero). If the Setpoint Option is enabled (F11), when the
weight or zero is displayed, the setpoint outputs will immediately turn ON if below SP1/SP2
target values or zero tolerance (SP3) will turn ON if within the preset tolerance from zero. If
the Analog Output is installed, the outputs will increase to maximum and the switched
output will open. If F4 is set to 1, 2, or 3, zero will be captured on power-up if the weight is
within ± 2% of scale capacity.

4.4 PROGRAMMING AND CALIBRATION MODE
SSW #/PROMPT DESCRIPTION
[F0 ] CALIBRATION ADJUST FEATURE
NOTE: TEST WEIGHTS MUST BE ON THE SCALE BEFORE ENTERING THIS STEP CALIBRATION
ADJUST IS A FINE ADJUSTMENT FEATURE TO BE USSED ONLY AFTER FULL CALIBRATION.
0 = Bypass OD and Go to SSW F1
[000000]
1 = Start span calibration adjustment. First place test weight on platform. Display
will show [000000] with the MSD (most significant digit) active (blinking). (If
PRINT is pressed with display showing [000000], the procedure is aborted).
Enter the value of the test weight.
- Press ZERO to increment the active digit by one
- Press TARE to move to the next lower MSD
- Press PRINT to accept displayed value and go to F1
- Press CLEAR to zero the display and start over
[F1 ] ZERO ADJUST
0 = Bypass SSW and go to F@
1 = Enter current initial weight on scale as zero. Display will count down from 15 while setting
the new initial. Scale motion will cause countdown to restart from 15.
- Press PRINT to start procedure
- Press CLEAR during countdown to abort procedure
[F2 ] LOAD CELL TYPE
0 = Analog load cell(s)
1 = Digital load cell/Power Module
[F3 ] CALIBRATION UNITS
1 = Pounds
0 = Kilograms

[F4 ] AUTOZERO MAINTENANCE (AZM, REFER TO SECTION 2.11)
AZM is a feature that maintains the displayed zero in the center of the zero increment. This step
selects the size of the window over which zero change is compensated for at the rate of 0.2
increments per second. If the weight exceeds the AZM window, then AZM is disabled. As long as
the weight is within the AZM window selected, the 8510 will remove 0.2 increments of the zero
change per second. AZM will correct for zero drift up to a maximum of ±4% of scale capacity, with
the center of the zero range determined during calibration.
Normal AZM is disabled when the 8510 is in the net weight mode. Selection 4 permits AZM to
operate in the net weight mode as well as in the gross mode when the weight on the scale is
within 3 increments of gross zero. When AZM is enabled, zero is captured at power-up if the
weight on the scale is within ±2% of scale capacity of gross zero.
Selection AZM Window Legal-For-Trade Application
0 AZM Disabled Not Applicable
1 ± 0.5 Increment (Gross Mode Only) Animal, Food, & Retail Scale
2 ± 1 increment (Gross Mode Only) All other Industrial Scales
3 ± 3 Increment (Gross Mode Only) Vehicle Scales
4 ± 3 Increment (Gross Mode Only) Not Applicable
[F5 ] PUSHBUTTON ZERO
0 = Pushbutton Zero Disabled
1 = ± 2 of Scale Capacity
2 = ± 20 of Scale Capacity
[F6 ] MOTION SENSITIVITY
The 8510 includes a weight in motion detector which requires three successive weight readings
within the selected range of either 1.0 or 3.0 increments for a “no-motion” signal. The motion
detector signal inhibits pushbutton or remote ZERO, TARE, and PRINT.
0 = Disable Motion Detector
1 = 1.0 increment sensitivity
2 = 3.0 increment sensitivity
[F7 ] FILTER SENSITIVITY
The 8510 has a low pass multi-pole digital filter that is selectable for various environmental
conditions. The display update rate is slowed slightly when more filtering is selected. By
selecting higher filter rates, more movement or vibrations to the scale platform can be filtered out.
0 = No added filtering (Least)
1 = Light filtering
2 = Medium filtering
3 = Heavy filtering
15
[F7.1 ] DigiTOL® LOAD CELL FILTER
DigiTOL® load cell bases provide a built-in digital filter that can interfere with slow speed filling or
batching operation. This filter MUST be disabled for setpoint applications. This step is only
displayed if the 8510 is configured for DigiTOL® load cell base.
0 = DigiTOL® Load Cell Filter Disabled
1 = DigiTOL® Load Cell Filter Enabled (default)
[F8 ] EXPANDED DISPLAY
This feature will allow the 8510 to display minor increments (0.1 d) on the display. This feature is
used for test purposes only. Operate in the normal display mode only.
0 = Normal display mode
1 = Minor increments are displayed
[F9 ] TARE MODE
When auto-tare is selected, a tare is taken whenever the 8510 is in the gross weight mode and the
scale settles on a weight greater than 5 increments above gross zero.
0 = Tare disabled. Advance to F11
1 = Pushbutton Tare mode only. Advance to F10
2 = Auto-Tare mode only
[F10 ] AUTO CLEAR TARE
When enabled, Auto Clear Tare will automatically clear the entered tare value if the weight has
settled to a no-motion condition at a weight greater than 10 d increments and then returned to less
than 0.5 d increments from gross zero.
0 = Disable Auto Clear Tare
1 = Enable Auto Clear Tare. Tare will clear with return to gross zero
NOTE: THE LEVEL L05 (“E” OR HIGHER REVISION SOFTWARE) AUTOMATICALLY DETECTS ANY
INSTALLED OPTION MODULES. IF THE SETPOINT HARDWARE IS CONNECTED, F11.1 WILL BE
THE NEXT PROMPT. IF BCD HARDWARE IS CONNECTED, F11.2 WILL BE THE NEXT PROMPT. IF
ANALOG HARDWARE IS CONNECTED, F11.5 WILL BE THE NEXT PROMPT. IF NO HARDWARE IS
ATTACHED, F11 WILL E THE NEXT PROMPT. ONLY VALID SELECTIONS ARE DISPLAYED.
[F11 ] SETPOINT OPTION SELECT (no hardware attached)
0 = Setpoint option not enabled. Proceed to F12
1 = Setpoint Option enabled. Proceed to F11.1
[F11.1 ] SELECT ZERO TOLERANCE RANGE
Zero tolerance range provides ability to select a bandwidth in which Setpoint SP3 is turned on.
0 = 0 Increments (SP3 output off)
1 = 1 d Increment
5 = 5 d Increments
- Press TARE to display selections
- Press PRINT to enter selection and advance to F11.3
