4 INST ALLATION AND COMMISSIONING
PRECAUTION: Please read this manual carefully before energizing the indicator. Perform the commissioning
operation according the procedure given here. Use trained personnel for cleaning, commissioning, checking and
service of the indicator. The interference of untrained personnel may cause some unwanted damages or injures.
Note: In this manual the term “Digital Load Cell“ will be refered to “DLC“.
4.1 Mechanical Installation
First of all please determine the place where your indicator can operate safely. This place should be clean, not
getting direct sun light if possible, with a temperature between -10 ºC and +40 ºC, humidity not exceeding 85%
non-condensing. Take care to the housing dimensions and the suggested panel hole dimensions given in
chapter 3.5. All the cables should be installed safely to avoid mechanical damages.
To avoid electrical noise protect your indicator which has very low input signal level from the equipment that
produces electrical noise, especially in panel mounting.
4.1.1 Jumpers
There are three jumpers on the instrument’s main board/weighing board for calibration and for switching on/off.
To change the position of this jumpers, open the housing and perform the necessary changes before energizing
the indicator.

4.2 Electrical Connections
4.2.1 Power Supply and Grounding
FT-12 is available with 230 V AC power supply or 24 V DC or 12 V DC power inlet. The 230 V AC indicators are
supplied with a power cable; the DC indicators are supplied with a special connector for the power inlet.
Prepare your power voltage according to your instrument’s power inlet. The DC connector pin configuration can
be found in Figure 4.2 below.
Definition
12 V / 24 V 1 3
0 V 2 2
Housing Gnd 3 1
Desk / Panel
The quality of the instrument’s ground will determine the accuracy and the safety of your indicator. A poor
ground can result in an unsafe condition if an electrical short cuircuit happens. A good ground connection is
needed to minimize extraneous electrical noise pulses. It is important that the instrument does not share power
lines with noise-generating equipment such as heavy load switching, motor control equipments, inductive loads,
etc. If the condition of the power line in the plant is bad, prepare a special power line and grounding.
If you have to service the indicator, turn off the power and wait at least for 30 seconds before interfering.
All connectors are at the rear side of the housings of desk and panel types. The stainless steel housings must
be opened to make the required connections. These connections must be done as described below.

FT-12 Technical Manual, Rev. 1.35 November 2010
Page 10 of 44
4.2.2 Standard Load Cell Connection
The load cell wiring should be made carefully before energizing to avoid damages to the weight indicator and
the load cells. The input resistance of the load cells that you want to connect should be more than 58 .
The sense pins of the instrument should be connected. In 4-wire installations the sense and excitation pins with
the same polarity should be short circuited at the connector side.

4.3 Commissioning
After making the required installations and connections to your indicator, turn the power on and perform
following steps:
Get familiar with the instrument’s setup mode (see chapter 6.1)
Set up the application mode (see chapter 6.2)*
Define the configuration parameters (see chapter 6.3)*
Define the scale parameters (see chapter 6.4)
Calibrate the scale (see chapter 6.5)
* Note: Most of the parameters can be skipped for later setup. Please take care for the parameters which may
be locked by the J2 calibration jumper in legal for trade applications (see Appendix 1: Setup and Calibration
Menu of the instrument).
If you want to use the Flintec IndFace Software for FT-12 then you have to set up the instrument’s standard
serial interface to host mode (see chapter 9.2) before you adjust all the configuration parameters.
After checking the performance of your weighing instrument you can begin to use the indicator.
If there are peripheral connections, first you should turn the power off; make the peripheral connections, perform
the required safety checks and energize the indicator. Then set the related parameters and check if the
peripheral devices are operating properly.
If required perform following additional steps:
Set up the memory functions (see chapter 7)
Set up the serial interfaces (see chapter 9.2)
Printer setup (see chapter 9.2)
Set up other optional inputs and outputs (see chapter 9.3 and 10)
