SITE PREPARATION
Environmental
The Model 225 Weight Indicator meets or exceeds all certification requirements within a
temperature range of 14 to 104 °F (-10 to +40 °C).
In order to keep cooling requirements to a minimum, the indicator should be placed out of
direct sunlight and to provide adequate air circulation, keep the area around the indicator clear.
Make certain the indicator is not directly in front of a heating or cooling vent. Such a location
will subject the indicator to sudden temperature changes, which may result in unstable weight
readings.
Insure that the indicator has good, clean AC power and is properly grounded. In areas subject
to lightning strikes, additional protection to minimize lightning damage, such as surge
suppressors, should be installed.
8200-M538-O1 y 225 Installation
Page 6
SITE PREPARATION, CONT.
The Model 225 Weight Indicator is a precision weight-measuring instrument. As with any
precision instrument, it requires an acceptable environment to operate at its peak performance
and reliability. This section is provided to assist you in obtaining such an environment.
Electrical Power
The 225 has been designed to operate from 90 to 264 VAC at 50/60 Hz. Note that a special
order is UnotU required for operation at 230 VAC.
CAUTION! - To avoid electrical hazard and possible damage to the indicator,
DO NOT, under any circumstance, cut, remove, alter, or in any way bypass the
power cord grounding prong.
On installations requiring 230 VAC power, it is the responsibility of the customer to have a
qualified electrician install the proper power cord plug which conforms to national electrical
codes and local codes and ordinances.
The power outlet for the indicator should be on a separate circuit from the distribution panel.
This circuit should be dedicated to the exclusive use of the indicator. The wiring should
conform to national and local electrical codes and ordinances and should be approved by the
local inspector to assure compliance.
To prevent electrical noise interference, make certain all other wall outlets for use with air
conditioning and heating equipment, lighting or other equipment with heavily inductive loads,
such as welders, motors and solenoids are on circuits separate from the indicator. Many of
these disturbances originate within the building itself and can seriously affect the operation of
the instrument. These sources of disturbances must be identified and steps must be taken to
prevent possible adverse effects on the instrument. Examples of available alternatives include
isolation transformers, power regulators, uninterruptible power supplies, or simple line filters.
Transient Suppression
The following recommendations will help to reduce transients:
y Always use shielded cables to connect signal wires to the weight indicator.
y Secure the cables in the cable clips provided inside the indicator.
y Connect the cable shield (indicator end only) to a ground point inside the indicator.
Keep wires that extend beyond the shield as short as possible.
y Do not run load cell or signal cables from the weight indicator along side or parallel to
wiring carrying AC power. If unavoidable, position the load cell and signal cables a
minimum of 24" away from all AC wiring.
y Always use arc suppressors across all AC power relay contacts (see recommendations
at
HUhttp://www.paktron.com/pdf/Quencharch_QRL.pdfUH).
y Use zero voltage switching relays, optically isolated if possible.

MAIN PC BOARD, CONT.
J1 (AUTO ON) – AUTO-ON JUMPER
When installed, this jumper will cause the indicator to power on automatically whenever power
is applied to the power input connector. If power is lost momentarily and then reapplied, the
indicator will turn on without pressing the ON key.
J2 (TEST) – TEST JUMPER
When installed, this jumper will turn the backlight on, ignoring the BACK LITE= setting.
J3 (8V) – 8V EXCITATION JUMPER
When installed, this jumper allows the 225 indicator to supply 8 VDC excitation voltage when a
remote (external) 12 VDC battery is used to power the indicator. To operate from the 12 VDC
battery, the load cell excitation voltage MUST be set to 8 VDC (J3 closed). Operating with the
load cell excitation voltage set to 12 VDC will result in an unstable weight display.
J4 (PWC1-8) and J5 (PWC9-16) – ACTIVE REMOTE OUT JUMPERS
When installed, these jumpers allow the 225 indicator to supply (source) 5 VDC to a solid-state
relay or other load of 200 ohms or greater. To operate from the 5 VDC source, the positive
connection from the relays must be connected to P15 (P16) pins 2 through 9 and the negative
wire from the relays to P15 (P16) pin 10 (GND). See Figure No. 9 for connector P15 location
and Figure No. 10 for connector P16 location.
For completely isolated outputs, J4 (J5) must be open (on one pin only or removed) and the
user must provide 5 to 12 VDC to P15 (P16) pin 1 (+SRC) and a ground return to the load.
The load must still be 200 ohms or greater and P15 (P16) pin 10 (GND) is not connected.
J6 (REMOTE IN) – REMOTE IN JUMPER
When installed, this jumper allows the 225 indicator to supply (source) 5 VDC to a remote input
circuit. Connecting P17 pins 1 through 9 to P17 pin 10 (GND) through a switch will cause the
selected action. See Figure No. 8 for connector P17 location.
For completely isolated inputs, J6 must be open (on one pin only or removed) and the user
must provide 5 to 12 VDC to P17 pin 1 (+SRC) and a ground return to the switch connected
to P17 pin 2 through 9. Note that P17 pin 10 (GND) is not connected.
J7 (+SEN) and J9 (-SEN) – SENSE JUMPERS
If the sense leads are NOT used, you must install jumpers at J7 and J9 (near the P13 and P14
terminal blocks). These jumpers connect the sense leads to the excitation leads. If sense
leads ARE used (as in motor truck scales), these jumpers should be open (on one pin only or
removed).
J8 (DLB) – DEAD LOAD BOOST JUMPER
For very low dead loads (less than 10% of the combined load cell capacity) connect J8, the
DLB (dead load boost) jumper on the printed circuit board.
J10 (GTC) – GND TO CHASSIS JUMPER
When installed, this jumper connects the analog circuit ground to the indicator chassis ground.

KEYPAD FUNCTIONS
The Model 225 indicator has 8 standard function keys, a full “QWERTY” alpha-numeric
keypad, 4 soft (programmable) keys and 4 navigation keys with an interactive ENTER key.
The keypad is used to enter commands and data into the indicator. This section describes
each key along with its normal function. Refer to Figure No. 12 or the actual indicator while
reading this section.
The membrane keypad is not to be operated with pointed objects (pencils,
pens, fingernails, etc). Damage to keypad resulting from this practice is NOT
covered under warranty.

TARE KEY
This key is a dual function key. Pressing the TARE key alone (Pushbutton Tare mode) will
cause the current gross weight to be stored as the new tare weight and cause the weight
display to change to the net weight display mode (NET will be shown on right side of
display). Pressing this key after entering a numeric value (Keypad Tare) will cause the
value entered to be accepted as the new tare weight.
NOTE: Tare weights equal to or greater than scale capacity cannot be entered. In
addition, the keypad tare weight division value must be the same as the scale division
value. For example, a unit with .005 lb as the division value will display ERROR if you
attempt to enter 1.003 for the tare weight.
NET/GROSS KEY
This key is used to toggle between the Net and Gross weight mode. The selected mode is
indicated by showing G for Gross weight or NET for Net weight on the display. Note that
the display will show an error (-NO TARE-) and the indicator will remain in the Gross
weight mode if the key is pressed and valid tare weight has not been entered.
UNITS KEY
Pressing this key will change the weighing units to the alternate units if selected during the
calibration and setup of the indicator. The available units of measure (BASE UNITS=
and CNVT UNITS=) are enabled or disabled in calibration and setup. The available units
include tons, pounds only, ounces, tonnes (metric tons), kilograms, grams and custom.
Note that not all combinations are supported.
ACCUM KEY
This key is used to display the contents of the 32 ID accumulators, the total Gross and Net
weight accumulators, the 200 ID storage accumulators, the Batcher bin accumulators and
the Count Function piece count accumulators. Note that the Total Gross, Total Net and
Count accumulators are updated with every print command. Refer to the NET/GROSS
ACCUMULATORS, ID STORAGE OPERATION (ID ACCUMULATORS) OR COUNT
OPERATION sections of this manual for more information.
TIME/DATE KEY
This key is used to program the time, date and consecutive number. Refer to the TIME,
DATE AND CONSECUTIVE NUMBER section of this manual more information.

PRINT KEY
Pressing this key will add the displayed Gross or Net weight or Piece Count to the
associated accumulator and initiate the transmission of weight and other data selected
during setup to the printer output port UunlessU the continuous data feature of the port was
enabled during calibration and setup.
NOTE! The indicator will not respond to the Print command unless the weight
display is stable. If displaying Gross weight, the only weight printed is Gross
weight. If displaying Net weight, the Gross, Tare, and Net weights are printed.
The Model 225 includes support for Cardinal’s
proprietary VISUALIZER Ticket and Label
Generation Software. VISUALIZER is a PC based
program that can design a ticket or label then
download the ticket information to the indicator.
The program also allows file transfer between the
indicator and the PC.
The 225 allows six programmable formats in
addition to the standard print tab settings format.
Print formats are selected by using the SHIFT and
PRINT keys in combination (refer to the Shift Key
section for details). NOTE! When the PRINT key
is pressed the indicator looks for the selected
format. If no VISUALIZER ticket is found it reverts
to the print tab settings.

Alpha-Numeric Keys
The alpha-numeric keys are used to enter commands and data into the indicator during
Calibration and Setup as well as during normal operations.
NUMERIC KEYS (1 to 9 and 0)
These keys are used to enter numeric data during the setup and calibration as well as
during normal operation of the indicator. Note that they have alternate meanings. In the
alphanumeric mode, when combined with the SHIFT key, their alternate meaning is output.
For example, pressing the SHIFT key and then the 4 key will output the $ dollar sign.
←⎯ /ESC KEY
This key has several functions. During Setup, when a setup parameter is displayed,
pressing this key will "backup" to the previous selection. Also note that on prompts requiring
a value to be entered, pressing the ←⎯ /ESC key will clear the value.
In normal operation, this key is used during numeric data input to delete a number entered.
If the last number entered is incorrect, press the ←⎯ /ESC key once to deleted the number.
If more than the last number is incorrect, press the ←⎯ /ESC key for each number to be
deleted. Note that if a number has not been entered, the indicator will ignore this key.
QWERTY KEYS
These keys are used to enter alpha data during Calibration and Setup as well as during
normal operations. Pressing the SHIFT key before pressing an alpha key will toggle the key
to output its alternate meaning. For example, pressing the SHIFT key then the A key will
output a lower case “a” (not a capital letter).
ENTER KEY
The ENTER key serves several purposes. During Calibration and Setup (as well as during
normal operations), pressing the key will retain the current setting and return the display to
the menu display. It is also used when entering or changing data to signal the completion of
data entry. The data entered will then be processed or saved.
During normal operations it is used in combination with the SHIFT key to increase the LCD
contrast.
SPACE
This key is used to enter a blank space during alpha-numeric data input for Calibration and
Setup as well as during normal operations. When combined with the SHIFT key, it is used
to decrease the display contrast.

SHIFT
This key is used for several functions. It is used in combination with the Navigation ENTER
key (red square key in center of the Navigation arrows) to enter the Calibration and Setup
mode.
During Calibration and Setup (as well as during normal operations), pressing the key before
pressing an alpha-numeric key will toggle the key to output its alternate meaning. For
example, when combined with an alphabetic key, the SHIFT key causes a lower case letter
(not a capital letter) to be output.
Shift Key Combinations
SHIFT, ESC, ACCUM KEY
The 225 will retain and display on command the maximum weight value measured since the
indicator has begun operation or since the maximum value was last cleared. The maximum
value is displayed by pressing the SHIFT key, the ESC key and then the ACCUM key when
the display is showing the FUNCTION= prompt. Press the ENTER key to exit and return
to normal operation.
SHIFT, ESC, PRINT KEY
This combination is used to change the selected print ticket format. Pressing the SHIFT
key, the ESC key and then the PRINT key when the display is showing the FUNCTION=
prompt. The display will change to show PRINT=X. Note that X is the current ticket
format selected.
If the setting displayed is acceptable, press the ENTER key to exit and return to normal
operation. Otherwise, using the numeric keys enter the new value for the ticket format and
then press the ENTER key to exit and return to normal operation.
0 = Print Tab Settings
1 = Default Print Format 2 = VISUALIZER Ticket 3 = VISUALIZER Ticket
4 = VISUALIZER Ticket 5 = VISUALIZER Ticket 6 = VISUALIZER Ticket
In addition to using the above key combination to change the print ticket format, the
operator (just prior to printing the ticket) can change the print ticket format at the end of the
weighing operation. This is accomplished by performing the normal weighing operation and
then pressing the desired format number (0, 1, 2, 3, 4, 5 or 6), followed by pressing the
PRINT key.
NOTE! When a print format is selected by either method, it will remain active
until changed by the operator.
