PRECAUTIONS
Static Electricity
CAUTION! This device contains static sensitive circuit cards and components.
Improper handling of these devices or printed circuit cards can result in damage to or
destruction of the component or card. Such actual and/or consequential damage IS
NOT covered under warranty and is the responsibility of the device owner. Electronic
components must be handled only by qualified electronic technicians who follow the
guidelines listed below.
ATTENTION! ALWAYS use a properly grounded wrist strap when handling,
removing or installing electronic circuit cards or components. Make certain that the
wrist strap ground lead is securely attached to an adequate ground. If you are
uncertain of the quality of the ground, you should consult a licensed electrician.
ALWAYS handle printed circuit card assemblies by the outermost edges. NEVER
touch the components, component leads or connectors. ALWAYS observe warning
labels on static protective bags and packaging and never remove the card or
component from the packaging until ready for use. ALWAYS store and transport
electronic printed circuit cards and components in anti-static protective bags or
packaging.
SITE PREPARATION REQUIREMENTS
The Cardinal 205 indicator is a precision weight-measuring instrument. As with any precision
instrument, it requires an acceptable environment to operate at peak performance and
reliability. This section is provided to assist you in obtaining such an environment.
Environmental
The Model 205 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-M024-O1 Rev G y205 Installation & Technical 5
SITE PREPARATION REQUIREMENTS
Electrical Power
The 205 indicator has been designed to operate from 90 to 264 VAC at 50/60 Hz. Note that a
special order is not 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.
The socket-outlet supplying power to the indicator should be on a separate circuit from the
distribution panel and dedicated to the exclusive use of the indicator.
The socket-outlet shall be installed near the equipment and shall be easily accessible.
Note that the power cord on the 205 (without the Battery Option) serves as the power
disconnect.
The wiring should conform to national and local electrical codes and ordinances and should
be approved by the local inspector to assure compliance.
On installations requiring 230 VAC power, it is the responsibility of the customer to have
a qualified electrician install the proper power cord plug that conforms to national electrical
codes and local codes and ordinances.
Electrical Noise Interference
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 indicator. These sources of disturbances must be identified and steps must be taken to
prevent possible adverse effects on the indicator. 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:
yAlways use shielded cables to connect signal wires to the weight indicator.
ySecure the cables in the cable clips provided inside the indicator.
yConnect the cable shield (indicator end only) to a ground point inside the indicator. Keep
wires that extend beyond the shield as short as possible.
yDo 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.
yAlways use arc suppressors across all AC power relay contacts (see recommendations at
http://www.paktron.com/pdf/Quencharch_QRL.pdf).
yUse zero voltage switching relays, optically isolated if possible.

INSTALLATION
Before beginning installation of your Model 205 Weight Indicator, make certain that the
indicator has been received in good condition. Carefully remove the indicator from the
shipping carton and inspect it for any evidence of damage (such as exterior dents or
scratches) that may have taken place during shipment. Keep the carton and packing material
for return shipment if it should become necessary. It is the responsibility of the purchaser to
file all claims for any damages or loss incurred during transit.
Mounting
NOTE! Should your 205 indicator come already installed on a scale, the following information
describing the installation of the indicator does not apply.
The Model 205 indicator is housed in a NEMA 4X/IP66 stainless steel wall or desk-mount
enclosure. The gimbal may be mounted on a desktop or other smooth, flat, horizontal surface
or may be mounted on a wall. Refer to Figure No. 1 for a layout of wall-mounting bolts.
If wall mounted, make certain the mounting surface is strong enough to support the indicator.
The mounting location should be where the display is easily viewed while being close enough
to provide the operator easy access to the keypad. Carefully lay out the mounting hole
locations, then drill and install the anchor bolts. Attach the gimbal to the wall and securely
tighten the retaining bolts.

Main PCB Jumpers
J1 – BATTERY CHARGE MODE
Place jumper J1 in the Full position when operating the indicator totally from battery power and
only recharging the battery pack when it is low. Place jumper J1 in the Trickle position when
operating the indicator from commercial power and using the battery pack to supply power only
in the event of a power loss.
J2 – AUTO-ON JUMPER
The AUTO-ON jumper J2, when connected, 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.
J3 – 8V EXCITATION JUMPER
The 8V EXCITATION jumper J3, when connected, sets the load cell excitation voltage to 8V
for operation with the 12 VDC battery. To operate from the 12 VDC battery, the load cell
excitation voltage MUST be set to 8 VDC (J3 closed). Battery operation with the load cell
excitation voltage set to 12V will result in an unstable weight display.
J4 AND J5 – SENSE JUMPERS
If the sense leads are NOT used, you must install plug-in jumpers at J4 and J5 adjacent to the
terminal block. These jumpers attach the sense leads to the excitation leads. If sense leads
ARE used (as in motor truck scales), these plug-in jumpers should be positioned on one plug-
in pin only or removed and stored for later use.
J10 – DEAD LOAD BOOST JUMPER
For very low dead loads (less than 10% of the combined load cell capacity) connect the dead
load boost jumper J10 on the printed circuit board.
J11 – 12V PWC SRC (SOURCE)
The J11 jumper, when connected (CLOSED) supplies 12 VDC @ 25mA from the 205 indicator
to a solid-state relay or other load of 200 ohms or greater. When J11 is OPEN (positioned on
one plug-in pin only or removed), the 12 to 24 VDC must be provided from an external source
to P10-6. The load must still be 200 ohms or greater.
Re-Installing The Rear Panel
After all terminations have been made, remove the excess cable from the indicator enclosure
and securely tighten each of the cable gland connectors. Do not over-tighten these connectors
but make certain they are snug. DO NOT USE TOOLS! Finger tighten only! Insure any
unused gland connectors are plugged.
1. Make certain no cables or wires are exposed between the main housing and rear panel and
then place the rear panel onto the main housing.
2. Secure with the 12 acorn nuts removed earlier. Follow a diagonal pattern when tightening
the acorn nuts.
3. If using a battery, slide the battery into the opening, until you feel resistance and the edge
of the battery is flush with the bottom of the indicator.
4. Replace the Battery Access Cover and install the three acorn nuts removed earlier,
securing the battery in place.

ON/OFF KEY
This key performs two functions. Pressing it when the indicator is off will apply power to the
indicator. If the indicator is already on, pressing this key will turn the indicator off.
ZERO KEY/REVIEW
Pressing this key will cause an immediate zeroing of the weight display up to the selected limit
of 4% or 100% of the scale’s capacity. This selection is made during the setup and calibration
of the indicator. Note the indicator will not respond to this command unless the weight display
is stable.
Pressing the ASTERISK key before the ZERO KEY/REVIEW key will enter the Review
mode of Setup and Calibration. Refer to the Setup Review section of this manual.
TARE/ENTER
Pressing the TARE key alone will store the current gross weight as the new tare weight and
the weight display will change to the net weight display mode (Net annunciator will turn on).
Pressing the ASTERISK key before the TARE/ENTER key serves two purposes. First,
when reviewing setup parameters, pressing the TARE/ENTER key will display the
current setting of the parameter. Second, the TARE/ENTER key is used to signal
completion of the entry of data and causes the indicator to process the data entered.

NET/GROSS KEY
This key is used to toggle between Net and Gross weight modes. The selected mode is
indicated by turning on the appropriate annunciator on the display. Note that if no valid tare
weight has been entered, pressing this key will cause a momentary “notArE” display error and
the indicator will remain in the Gross weight mode.
UNITS / WLEFT ARROW KEY/TEST
This key is used for several functions. In normal operation, this key is used to select the units
in which the weight is to be displayed. The available units of measure ("unit1" and "unit2") are
selected in setup. The available units include tons, pounds only, pound-ounces, ounces only,
Tonnes (metric tons), kilograms, and grams. Note that not all combinations are supported.
During setup, this key is used to advance the cursor left to the next position when
inputting setup parameters.
Pressing the ASTERISK key before the UNITS/LEFT ARROW KEY/TEST key will enter
the Test mode. Refer to the description of the ASTERISK key below for details.
ASTERISK / SUP ARROW KEY
This key is used for several functions. During setup, when a setup parameter (not a parameter
value) is displayed, pressing this key will "backup" to the previous prompt. Also during setup,
when a parameter value is displayed, pressing this key will "toggle" between the different
available values for the setup parameter. In normal operation, this key is used in conjunction
with the other keys on the keypad to access additional indicator features. These features and
their associated key combinations are as follows:

ASTERISK, UNITS KEY
This combination will enter the Test mode. The Test mode is used to conduct a test
of all display elements. The test consists of 5 cycles, each lasting about one second:
1. All horizontal segments will turn on (no annunciators).
2. All vertical segments and decimal points will turn on (no annunciators).
3. All annunciators will turn on.
4. All display elements off.
5. The model number (205) and the software version X.X.
6. The calibration numbers (C1 to C4).
ASTERISK, PRINT KEY
This combination is used to change the selected print ticket format. Pressing the
ASTERISK then the PRINT key will display a prompt "Prt=". Press the TARE/ENTER
key to show the current value. If the setting displayed is acceptable, press the
TARE/ENTER key again to save it. Otherwise, press the ASTERISK/UP ARROW key
to "toggle" between the different available values, then press the TARE/ENTER key to
save it. Allowable values are:
0 = print tab settings 1 = visual ticket format 1 2 = visual ticket format 2
NOTE! When a print format is selected, it will remain active until changed
by the operator.
PRINT KEY
Pressing this key will add the displayed gross or net weight to the associated accumulator and
initiate the transmission of weight and other data depending on the Print Tab Settings (see
example) via the selected printer output port (see Port= under Print menu) unless the
continuous data feature of this port was enabled during setup and calibration. Note that the
indicator will not respond to this 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 will print.
The 205 includes support for visual tickets. Visual
tickets are designed by the PC based programs
Visual Print or n Control, then downloaded to the
indicator. The 205 allows two programmable formats
in addition to the standard print tab settings format.
Print formats are selected by using the ASTERISK and
PRINT keys in combination (refer to the next section
for details). NOTE! When the PRINT key is pressed
the indicator looks for the selected format. If no visual
ticket is found it reverts to the print tab settings. TICKET EXAMPLE

ANNUNCIATORS
Annunciators are turned on to indicate that the display is in the mode corresponding to the
annunciator label or that the status indicated by the label is active. The annunciators flash on
and off to indicate that the indicator is waiting for input from the keypad for the mode indicated
by the flashing annunciator. Refer to Figure No. 9 for the location of the annunciators.
ZERO
This annunciator is turned on to indicate that the weight displayed is within +/- 1/4 division of
the center of zero.
[\ (STABLE)
This annunciator is turned on when the weight display is stable. When off, it means that the
change in successive weight samples is greater than the motion limits selected during setup.

SETUP AND CALIBRATION
Your Model 205 indicator has been
thoroughly tested and calibrated before
being shipped to you. If you received the
indicator attached to a scale, calibration
is not necessary. If the indicator is being
connected to a scale for the first time or
recalibration is necessary for other
reasons, proceed as indicated.
The calibration switch is located on a
bracket on the inside of the enclosure
rear panel. You may gain access to this
switch simply by removing the calibration
switch access screw on the rear panel.
Refer to Figure No. 9.
During the setup and calibration process it will be necessary to enter operational
parameters via the 205 keypad. Pressing the TARE/ENTER key will cause the data
entered or displayed to be retained and the 205 to advance to the next prompt. The
functions of numeric keys are replaced by using the UNITS/LEFT ARROW and the
ASTERISK/UP ARROW keys. The cursor location is identified by the blinking character
and can be advanced to the left to the next position by pressing the UNITS/LEFT ARROW
key. Pressing the ASTERISK/UP ARROW key will change the blinking character to the
next value. Continue to press this key to "toggle" between the different available values
for the setup parameter. Pressing the ASTERISK/UP ARROW key when a setup
parameter (not a parameter value) is displayed, will "backup" to the previous prompt.
DO NOT operate the keypad with pointed objects (pencils, pens, etc).
Damage to keypad resulting from this practice is NOT covered under warranty.
