1.0 INTRODUCTION
•IPSW scales provide accurate, fast and versatile general purpose type weighing
scales with parts counting, percentage weighing and check-weighing functions.
•IPSW scales have LED’s next to the display to indicate when a weight is below
the low limit, in between the limits or above the high limit. These can work in
conjunction with an audible alarm for check weighing as well as the display
showing LOW, OK and HI.
•IPSW scales can be supplied with an optional RS-232 bi-directional interface and
real time clock (RTC). In order to maintain the IP washdown rating this feature is
installed before leaving the factory.
•IPSW scales have a sealed keypad with color coded membrane switches, a large
easy to read liquid crystal display (LCD) and a green backlight.

3.0 INSTALLATION
UNPACKING3.1
The scale has already been adjusted to work with the platform and has been configured for
this application. The platform and indicator have been calibrated as a pair and must be used
together.
LOCATING3.2
The scale should not be placed in a location that will
reduce the accuracy.
Avoid extremes of temperature. Do not place in
direct sunlight or near air conditioning vents.
Avoid unsuitable tables. The table or floor must be
rigid and not vibrate.
Avoid unstable power sources. Do not use near
large users of electricity such as welding equipment
or large motors.
Do not place near vibrating machinery.
Avoid high humidity that might cause condensation.
Avoid direct contact with water. Do not spray or
immerse the scale in water.
Avoid air movement such as from fans or opening
doors. Do not place near open windows or air-
conditioning vents.
Keep the scale clean. Do not stack material on the
scale when it is not in use.

SETTING UP THE SCALE3.3
Remove the Indicator from its box and fix it to the U shaped bracket using the
two fixing handles. Take the Indicator and place it onto the pillar ensuring the
slack cable is pushed inside. Fix the Indicator to the pillar using the screw
provided.
Remove all upper internal packaging, place the pillar into the base bracket
fitting and remove the complete machine from the box. Remove any plastic
bags that may have been used for protection.
Fix the pillar to the base bracket fitting using the screws provided
Adjust the viewing angle of the Indicator to the ideal position and tighten two
the locking handles.
Level the scale by adjusting the adjusting feet until the bubble is in the center of
the level indicator. If the scale rocks, re-adjust the feet.
NOTE: Use of a food-safe grease is recommended on the threaded part of
the feet to keep them turning freely.
Attach the power input connector to the indicator, plug in and turn on the
external power supply and press the [On/Off] key. The software revision
number will be displayed followed by a self-test showing all digits before the
zero is displayed along with the unit of weight that was last used.
Optional connections to RS232 port and relay wiring port should be made if
required.

4.0 KEY DESCRIPTIONS
Used to reset the display to zero.
Tares the scale. Used to deduct and store the weight currently
on the scale if it is not required as part of the final weighing
result.
A secondary function, is of an “Enter” key used when
setting up a value for the Parameters.
Selects parts counting. Used to set the sample quantities while
parts counting.
A secondary function, is of incrementing the active digit when
setting a value for Parameters.
Selects the weighing unit to be displayed from those which are
enabled. See parameter S1 in section 7.4 of this manual.
A secondary function, is to move the active/flashing digit to
the left when setting values for Parameters.
Selects the Function parameters of the scale.
A secondary function (C) is to act as a clear key when clearing
an accumulated total.
Sends the results to a PC or a Printer using the RS-232
interface. It also adds the value to the accumulation memory if
the accumulation function is not automatic.
A secondary function (ESC) is to return to normal operation
when the scale is in a Parameter setting mode.
To switch the Indicator on or off.
The scale will store the weighing unit and the check weighing
values currently in use if power is powered off. These will be re
called when the Indicator is next powered on
