CHAPTER 1 - OVERVIEW
Introduction Congratulations on your purchase of a Hardy Instru-
ments Any-Weigh™ Bench Scales. Behind your pur-
chase is over eighty years of quality, reliability and
technical innovation.
The Hardy Any-Weigh™ Bench Scales are designed
for table top or floor applications requiring high accu-
racy and reliability. The covers are all stainless steel
for durability. The bases have no bearings, spirit lev-
els, or moving parts that can be damaged or wear out.
The active element of the scale are precision strain
gauge load sensors.
NOTE: Any-Weigh™ is a trademark of Hardy Instruments
Incorporated.
Description The basic Any-Weigh Bench Scale consists of three
major components:
1. Stainless Steel Top Cover.
2. Lower Frame Assembly with Four Load Cells
3. Four Leveling feet.
TheStainlessSteel
Top Cover The top cover is a single piece constructed of series 300 Stainless Steel. The cover provides a weighing
surface and offers protection to the load cells and
electronics.
Lower Frame
Assembly The lower frame comes equipped with four leveling feet, four load cells, a shock load and corner overload
protection. The lower frame is made of coated mild
steel.
Universal Scale
Interface Directly attach the scale’s 15 foot cable to any weigh-
ing instrument or controller. If interfacing with a
Hardy Controller, you can take full advantage of
WAVERSAVER®and C2®Electronic Calibration.
NOTE: WAVERSAVER®and C2®are registered trademarks
of Hardy Instruments Incorporated.

Any-Weigh™ Series Bench Scales

DeviceNet™ Scale With DeviceNet™ you can use the scale to provide a
weight output to any point on a DeviceNet™ Net-
work. This version also incorporates both the
WAVERSAVER®and C2®technologies. The
DeviceNet™ Scale comes with a fifteen inch mini-
mum length pig-tail connector.
NOTE: DeviceNet™ is a trademark of the Open DeviceNet
Vendor Association.
Analog Scale The Analog Scale provides a 4-20mA output directly
proportional to the weight reading. This version offers
a low-cost, solution for bringing analog weight read-
ings directly into a control system. The Analog Scale
requires minimal additional wiring or hardware and
comes with a 15 foot shielded 2 wire cable.

CHAPTER 3 - INSTALLATION
Preinstallation
Precautions Do not store or operate the scale out of its specified
temperature range. (See Temperature Ranges in Chap-
ter 2)
Do not store other equipment on the scale when it is
not in use or in storage.
Do not allow a build-up of debris on, around or under
the scale.
Do not set the scale in water or allow water to settle
around the scale. Provide Proper drainage.
Do not let moisture get on or into any of the electrical
interconnections.
Do not allow static or other electrical discharges
through the scale.
Do not try to remove the top plate.
Do not try to repair the scale. Contact Hardy Instru-
ments Technical Support Department for any and all
repairs.
Unpacking The Any-Weigh Bench scales are shipped fully
assembled and only require adjustment of the leveling
feet. If there is any damage to the shipping container
or to the scale, save all the packaging material and file
a report with the shipper.
Leveling the Scale Step 1. Place the spirit level across each corner
and adjust if necessary to level the corners.
(See Fig. 3-1)

FIG. 3-1 LEVELING CORNERS
Step 2. To level the platform, turn the leveling feet
clockwise to lower the scale corner, or
counter clockwise to raise it until you get a
level reading. (See Fig. 3-2)
FIG. 3-2 LEVELING FEET
Step 3. Place a spirit level across the center of the
bench scale. Check for level and adjust the
leveling feet if necessary. (See Fig. 3-3)

Step 5. Adjust the leveling feet if necessary.
Universal Scale
Electrical Connections Make sure the cable is not pinched and is clear of the
feet. The Bench Scale requires a recommended DC or
AC excitation voltage of 5 volts with a maximum of
15 volts. Wire the Scale cable to an instrument or
indicator following the color code label found on the
upper frame or as follows:

NOTE: You should also have an installation drawing that
came with the bench scale (Drawing # 0588-0097)
which also has the wiring diagram described.
Analog Scale The fifteen-foot, 2 wire shieldedcable provides power
to the Analog Scale and transmits the 4-20 mA weight
signal. The scale must have from 15 VDC to 50 VDC
across its two loop wires at up to 20 mA (Full Scale
Output). Since all devices in the output/power loop
are in series, the minimum power supply voltage, 20
mA, must equal the total voltage drop across all of the
other devices in the loop plus 15 VDC for the ANY-
WEIGH Analog Scale.

Carefully note which wire is connected in the loop to
maintain correct polarity within the loop. To reduce
the change of ground loops do not connect any of the

CHAPTER 4 - CONFIGURATION
SCOPE The Universal Scale and the Analog Scale do not
require any configuration. The DeviceNet scale con-
figuration consists of setting the baud rate and node
address on a DIP switch which is accessible through
an access port on the bottom of the scale.

Configuration
NOTE: Be sure to configure the DeviceNet Scale before plac-
ing any vessels or containers on the scale.
DIP Switch (S1)
Configuration Configuring the DIP switch sets the following:
1. Baud Rate
2. Node Address
DIP Switch
Location The DIP Switch is located through an access port on the bottom of the scale. (See Fig. 4-1)

Accessing the DIP
Switch Tilt the scale up until you can reach the DIP Switch access port or if it is more convenient turn the scale
upside down so that bottom is facing up to reach the
DIP Switch access port.
NOTE: Scale must be connected to earth ground from the
Chassis Ground Attachment Point. (See Fig. 4-1)
