4 INSTALLATION 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.
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 Ω. 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.
5 FRONT PANEL AND KEYPAD 5.1 Weight Display and Status LEDs Figure 5.1 Front panel view of FT-12 The weight display of FT-12 is a 6 digit LED with 14 mm or 20 mm height. At the right side of the display there are 3 status LEDs for indicating “Gross”, “Net” and the standard unit “kg”.
5.2 Keypad The meaning of the front panel keys and the key functions are: FT-12 Meaning Power On/Off: This key is used for turning the instrument on or off. To switch off the key must be pressed and hold at least for 2 seconds. There is no On/Off key on panel type housings. Function : This key is used in combination with other keys to enter any function or to quit without saving. Info: This key is being used to view Total and CN information.
6 SETUP AND CALIBRATION 6.1 Basics 6.1.1 Basic Setup Keys on the Frontplate The symbols located on the lower right corner of each key indicate the function of the keys in the setup menu. The basic meanings of these keys are given in the table below.
6.2 Application Programmes Besides basic weighing the FT-12 indicator can be used in different common applications such as check weighing (over/under), peak hold, dynamic weighing (animal weighing) and automatic filling. The status LEDs located at the left side of the display and the digital I/O have different meanings according to the selected application mode. The meanings and the structure of the digital I/O are given in chapter 10. 6.2.
appears on the display. An alarm condition can be stopped by pressing the key. Starting or resetting the peak hold process can be also be done by a digital input. 6.2.4 Dynamic Weighing The dynamic weighing mode generally is used for weighing unstable objects like animals. First the threshold value (parameter [101]) and the time parameter (parameter [103]) should be defined in the setup mode (see chapter 6.2.6).

[202 X] Power On Zero This parameter setting controls if after power-on the scale will get automatically zeroed if the weight is in the percentage of the zeroing range. If the weight is not in the zeroing range the display will show [E E E ] message until you press the .
6.5 Scale Calibration [3--] Calibration Block [30-] Calibration [300 ] Gravity This parameter should be used in the scale that will be verified in two stages by gravity adjustment (in legal metrologic applications). This parameter should not be touched in other applications. If you enter a value in this parameter before calibration (as six decimal digits, e.g. enter “798564” for “9.
will show the [WAıt ] message during the span adjustment under load. Approximately 10 seconds later the display will show the [SAvE ] message. You can confirm the “Save span adjustment under load” by pressing or cancel it by pressing the key. 7 MEMORY OPERATIONS 7.1 ID Memory FT-12 has two ID codes and the capability to assign clear-text names to them for print out. There are also 99 ID memories which can be shared between the two IDs in any way.
8 ALIBI MEMORY AND LEGAL METROLOGICAL RECORDS If the alibi memory is installed and activated, the indicator keeps the latest 149 764 weighing records in this memory. The recorded data can be viewed on the indicator’s display or exported via serial port. To find a definite record you have to enter parameter [802]. After reaching the desired record, the recorded data can be viewed in the display. If needed you can print this record together with the following 9 records by pressing the key.

9.3 Ethernet Option FT-1x series indicators which are equipped with an Ethernet option can be connected to Ethernet TCP/IP or Modbus RTU over Ethernet networks as described below. 9.3.1 Electrical Connections The pin configuration of the RJ45 Ethernet connector is described below: 1 2 1: Link LED 2 Activity LED State Off Amber Green Pin no.
The Ethernet setup can be done by using the Ether X PC software. Note: For older instruments the configuration will be done by the Ethernet Device Installer PC software, see separate document on the Flintec Product-CD.
Frequently Asked Questions (FAQ) Question: Answer: The Ether X could not reach the FT-1x instrument. 1. Check the local network connection 2. Check if the IP address of the indicator is convenient for your network 3. Check the PC Ethernet output with other network instruments 4. Check the existence of the Ethernet related parameters in the instrument setup (see chapter 8.3.3). If you cannot not see these parameters in the setup, please check the proper installation of the Ethernet board. 5.
