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.
Environmental
In general, the 777 Indicator will perform
well 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 instrument 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.

SITE PREPARATION REQUIREMENTS
The 777 Programmable Weight Indicator is a precision 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 777 is designed to operate from 90 to 260 VAC at 50/60 Hz. No special order is 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 models 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 777 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 777. 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.
CAUTION! When in parallel runs, locate Load Cell cables a minimum of 24 inches
away from all AC wiring.
INSTALLATION
Unpacking
Carefully unpack and remove the indicator from the packing box. Inspect the unit for any signs
of damage due to shipping, such as exterior dents and scratches. Retain the packing and
shipping carton for return of instrument if necessary. It is the responsibility of the Purchaser to
file all claims for any damages or loss in transit incurred, unless the responsibility has been
accepted by the Seller in its proposal.
Placement
Place the indicator on a stable, vibration-free location, either a desk or solid table or wall
mounted. Be certain all cords and cables are out of normal traffic. If wall mounted, make
certain that the structure and mounting bolts are of sufficient strength to support the 777.
It is the responsibility of the customer to provide adequate mounting
hardware appropriate to wall mounting conditions assuring safety to both the
operator and the instrument.

INSTALLATION, Cont.
Load Cell Connection
The load cell is connected to the 777 scale input board via a DE-9P connector. Figure No. 8
shows the pin identification for the connector. Make certain the pins are correctly identified
before soldering a wire to them. Make certain that the connector retaining screws are used to
hold the load cell cable connector securely to the scale input board.
NOTE:
The 777 is shipped
with the sense jumpers J5 and J6 (located on the Scale Input Board) removed for use with
load cell installations that use sense leads (as in motor truck scales). If you don't use sense
leads in your load cell installation, insure jumpers J5 and J6 are connected or placed on both
pins to connect the sense leads to the excitation.
Load Cell Connection 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 +SENSE, -SENSE
terminals on the indicator and the +EXCITATION, -EXCITATION wires of the load cells or the
+SENSE, -SENSE terminals of the load cell trim board or the section seal trim board. For the
indicator to use the sense wires, the SENSE jumpers J5 and J6 must be open on the Scale
