INSTALLATION
1. Unpacking:
2. Electrical Requirements:
3. Environmental Requirements:
4. Start Up:
Unpack the balance. Save the packing container for future use.
The balance requires very stable power. It works on 230V AC supply
with PROPER EARTHING. The power outlet used for the balance should not
be shared with any other devices which draws current in inconsistent manner
likeAir Conditioner or Refrigerator etc.
For best results, the balance should be placed on a level surface which
is free from drafts. It should not be exposed to direct sunlight or radiated heat.
Table used for balance should be sturdy and should not transmit vibration from
other equipments and free from the movement of people. No vibration
producing equipment should be operated on the same platform as balance.
Power is supplied to the scale through a 3 core AC mains cord attached
to the scale. Insert the 3 pin plug of the power supply onto a proper mains
outlet. Switch on the balance using the switch on the scale.
Scale goes through self test and subsequently starts displaying weight.
Press key to display zero weight.
NOW THE SCALE IS READY FOR WEIGHING.
With battery backup option, there is a need to charge the battery regularly
to prevent loss of backup time. The scale can be switched off using the switch
provide on the scale. Do not switch off the main power to the scale even when the
scale is not in use. Keeping the mains power on will charge the battery and will be
ready to use when the input power fails.

PRINT OPTION
CT/CP series weighing scales can be attached to a serial printer for your printing
needs. Print out can be programmed to suit most of the printing requirements.
Note that the printer should have a serial port and baud rate of the scale and printer
should be same. 2 baud rates are available with the scale i.e. 2400 and 4800.
Printing option and patterns are controlled by parameters.
They are
There are 4 options
i) - Press key to start printing weight
and other details programmed as per (b), (c) and (d) below.
ii) - Printing is initiated when the weight kept on the pan
becomes stable.
iii) - All the displayed weights are printed along with
other details programmed as per (b), (c) and (d) below.
iv) - To print weights stored in memory along with details
programmed as per (b), (c) and (d) below.
Printer format. Five printout formats are available.

BI-DIRECTIONAL RS232-INTERFACE
Bi-directional RS-232 interface is provided in these scales to communicate with
devices like computer, printer etc. The interface is provided through a nine pin D-
type connector provided in the side connector plate of the scale. Connections are
as below.
Pin 2 – RXD – Receive Data
Pin 3 - TXD – Transmit Data
Pin 7 – Ground.
The Serial data transmitted and received are in standard ASCII mode ( +/- 5V) -
ASYNCHRONOUS , 8 BITS, NO PARITY, 1 STOP BIT.
Baud rate : 2400 OR 4800 SELECTABLE.
The data format for weight output is
<+/->WWWWWW.WWb <kg/lt> <CR><LF> ( 15 characters)
where WWWWWW.WW is the weight
b – blank space - 20 hex
CR- Carriage Return – 0D hex
LF – Line feed - 0Ahex
for example, weight 85.12 will be sent as
+000085.12bkg<CR><LF>
where <CR> is carriage return (0D hex) & LF is line feed (0A hex), b=BLANK
SPACE. The balance could be controlled by an external device like computer
with the following commands.
Z - Tares the balance.
W# - Number of times, the weight data is to be transmitted through the serial port.
# can be any number from 1-9.

STORAGE OF WEIGHTS IN MEMORY
Upto 100 weights can be stored in memory and recalled if required. The scale also
computes the total weight of all the weights in memory. To use this option, set
ACCU function to ON in SETUP functions. See relevant section.

AUTO POWER OFF
CCS series weighing scales have a built in auto power off facility, where in the
displays will be switched off , if any keys are not operated for approx. 5 minutes.
This will reduce power consumption and if the scale is being used with battery, it
can enhance the discharge time of battery.
To come out ofAuto Power Off mode, Press key.
Ensure to enable this feature in the mode.
Power saving mode feature will further enhance the battery backup time by
making switching off the display whenever the weight displayed is zero. The scale
will come out of Power saving mode when the displayed weight is not zero.
Ensure to enable this feature in the mode.
Peak hold feature will enable the scale to hold the display to the maximum
weight (Peak weight) displayed. When used in this mode, the scale will be
continuously displaying the maximum or peak weight measured by the scale, even
after the weight is removed from the pan.
For using this mode, this function should be enabled in the mode.
For putting the scale into PEAK HOLD mode,
Press and keys simultaneously.

PIECE COUNTING MODE
Contech CCS series scales can be used for piece counting purposes. Piece
calibration of 25 items can be stored in memory. Accuracy of piece counting
depends on the uniformity in weight of the items and the sample size used for piece
calibration. Better the weight uniformity and more the sample size, better will be
the accuracy.
Use SETUP function to select proper piece counting mode before using. There is
an option to select 1, 10, 25 or none piece counting modes. See relevant section in
SETUP functions for more details.
