INTRODUCTION
The TCW series of scales provides an accurate, fast and versatile series of general
purpose weighing scales with counting, % weighing and check-weighing functions.
There are 2 series of scales within the range, TCW scales use kilograms as the
default unit and the TCWa range are changeable from pounds to kilograms. The
scales in these series share the same functions but special instructions will be given for
the TCWa series to account for the ability to change weighing units.
There are 4 models in each series, with capacities up to 30 kg.
They all have stainless steel weighing platforms on an ABS base assembly.
All the keypads are sealed, colour coded membrane switches and the displays are
large easy to read liquid crystal type displays (LCD). The LCD’s are supplied with a
backlight.
All units include automatic zero tracking, audible alarm for pre-set weights, automatic
tare, pre-set tare and an accumulation facility that allows the count to be stored and
recalled as an accumulated total.

INSTALLATION
GENERAL INSTALLATION
The scales should be sited in a location that will not degrade the accuracy.
Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning
vents.
Avoid unsuitable tables. The tables or floor must be rigid and not vibrate. Do not place
near vibrating machinery.
Avoid unstable power sources. Do not use near large users of electricity such as
welding equipment or large motors.
Avoid high humidity that might cause condensation. Avoid direct contact with water. Do
not spray or immerse the scales in water.
Avoid air movement such as from fans or opening doors. Do not place near open
windows.
Keep the scales clean.
Do not stack material on the scales when they are not in use.
INSTALLATION of TCW SERIES
The TCW Series comes with a stainless steel platform packed separately. Place the
platform in the locating holes on the top cover. Do not press with excessive force as this
could damage the load cell inside.
Level the scale by adjusting the four feet. The scale should be adjusted such that the
bubble in the spirit level is in the centre of the level and the scale is supported by all
four feet. If the scale rocks readjust the feet.
Attach the power supply cable to the connector on the bottom of the scale. Plug in the
power supply module. The power switch is located on the base near the front of the
scale.
KEY DESCRIPTIONS
Zero or
Set the zero point for all subsequent weighing. The display shows zero.
A secondary function , or "Enter" key when setting parameters or other functions.
Tare or
Tares the scale. Stores the current weight in memory as a tare value, subtracts the tare
value from the weight and shows the results. This is the net weight. Entering a value
using the keypad will store that value as the tare value.
A secondary function , of incrementing the active digit when setting a value for
parameters or other functions.
Limit or
Sets the limits for check weighing. Allows setting of either the low limit or the high limit
or both.
Secondary function , is to move the active digit to the right when setting values for
parameters or other functions.
%
Enters the percent weighing function. Allows the weight, unit weight, and count to be
seen when parts counting.
Secondary function , is to move the active digit to the left when setting values for
parameters or other functions.
Func or
Used to select the function of the scale. If the scale is weighing it will select parts
counting. Of it is not in weighing mode it will return the user to weighing.
Secondary function ( C) , is to act as a clear key when setting values for parameters or
other functions.
Print or
To print the results to a PC or printer using the optional RS-232 interface. It also adds
the value to the accumulation memory if the accumulation function is not automatic.
Secondary function (ESC) , is to return to normal operation when the scale is in a
parameter setting mode.
TCWa SCALES ONLY
Kg/Lb key
This key will select either kilograms or pounds for the weighing unit.

OPERATION
ZEROING THE DISPLAY
You can press the ZERO/ENTER key at any time to set the zero point from which all
other weighing and counting is measured, within 4% of power up zero. This will usually
only be necessary when the platform is empty. When the zero point is obtained the
display will show the indicator for zero.
The scale has an automatic rezeroing function to account for minor drifting or
accumulation of material on the platform. However you may need to press the
ZERO/ENTER key to rezero the scale if small amounts of weight are shown when the
platform is empty.
TARING
Zero the scale by pressing the ZERO/ENTER key if necessary. The zero indicator will
be on.
Place a container on the platform, a value for its weight will be displayed.
Press the TARE key to tare the scale. The weight that was displayed is stored as the
tare value and that value is subtracted from the display, leaving zero on the display.
The "TARE" indicator will be on. As product is added only the weight of the product will
be shown. The scale could be tared a second time if another type of product was to be
added to the first one. Again only the weight that is added after taring will be displayed.
When the container is removed a negative value will be shown. If the scale was tared
just before removing the container this value is the gross weight of the container plus all
product that was removed. The zero indicator will also be on because the platform is
back to the same condition it was when the ZERO/ENTER key was last pressed.
