3. INSTALLATION
3.1 Site Preparation Requirements
The Nuweigh Model JAC190 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.
3.1.1 Environmental
The JAC190 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.
8400-M022-O1 Rev A 02/11
Page 11
Page 5
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.
3.1.2 Electrical Power
The JAC190 has been designed to operate from 100 to 240 VAC @
0.4A Max. at 50/60 Hz. Note that a special order is not required for
operation at 230/240 VAC.
JAC190 Installation & Technical
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
JAC190 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.
For outdoor operations, the socket-outlet must provide GFCI
(ground fault circuit interrupter) protection.
On installations requiring 230/240 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.
8400-M022-O1 Rev A 02/11
Page 12
JAC190 Installation & Technical
Page 6
3.1.3 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 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.
3.1.4 Transient Suppression
The following recommendations will help to reduce transients:
Always use shielded cables to connect signal wires to the weight
indicator.
Secure the cables in the cable clips provided inside the indicator.
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.
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.
Always use arc suppressors across all AC power relay contacts (see
recommendations at www.paktron.com/pdf/Quencharch_QRL.pdf).
Use zero voltage switching relays, optically isolated if possible.

3.2 Mounting
6.00"
Clearance for
#10 size screw
Before beginning installation of your Model JAC190 Indicator, make
certain that it has been received in good condition. Carefully
remove it 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.
NOTE! Should your Model JAC190 indicator come already
installed on a scale, the following information describing the
installation of the indicator does not apply.
The Model JAC190 indicator is housed in a Thermoplastic IP69K
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 wallmounting bolts.
JAC190 Installation & Technical
Figure No. 1
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.

3.4 Load Cell Connections with Over 30 Feet of Cable
For installations with over 30 feet of cable between the indicator and the
load cells, sense wires should be used. The sense wires must be
connected between the +SENS, -SENS terminals on the indicator and the
+EXCITATION, -EXCITATION wires of the load cells or the +SENS, SENS terminals of the load cell trim board or the section seal trim board.
3.5 Sense and Dead Load Jumpers
J1 (+SEN) and J2 (-SEN) – Sense Jumpers
If the sense leads are NOT used, you must install the +SEN and -SEN
jumpers at J1 and J2 (near the P5 terminal block). These jumpers
connect the sense leads to the excitation leads. If sense leads ARE used
(as in motor truck scales or installations with over 30 feet between the
indicator and load cells), these jumpers should be open (on one pin only)
or removed.

conversion factor (span) without affecting the zero calibration value
stored during the last calibration. This minimizes placing and removing
test weights and is especially useful when checking high capacity scales.
This method uses two calibration points, CAL1= and CAL2=. The value
of the test weight is entered when CAL1= is displayed and the ZERO key
is pressed when CAL2= is displayed.
CAL1= – First Calibration Weight
1. The display will show CAL1=. This is the first of two calibration
steps. This weight is the TEST WEIGHTS (TEST LOAD).

4.6.4 Single-Point for Zero Only (Only Zero) Calibration
This calibration method requires no test weight, an empty scale and
establishes a new zero without affecting the conversion factor (span).
This is useful to regain the full range of zero limit when the dead load of
the scale has changed. This would occur for example, if a guard rail has
been added to the scale platform. This method uses two calibration
points, CAL1= and CAL2=. The TARE key is pressed when CAL1= is
displayed and the ZERO key is pressed when CAL2= is displayed.

9.2.2 Preset Weight Comparators Operation
The preset weight comparators are used to control peripheral
devices used in some form of process control. The number of
comparators used depends upon system needs.
For example, in a simple filling operation, a single comparator may
be used to open or close a gate which dumps material on the scale.
In a more complex application, more comparators may be used for
high speed/low speed filling.
The d out= (Digital Output) setup parameter selects how many
comparators are being used and the state of the output when the
scale weight is below the preset target or cutoff weight. The output
can be in one of two states: connected to the common pin on the i/o
connector or not connected to the common pin on the i/o connector.
When the scale weight is greater than or equal to the cutoff weight,
the output will change state.
