Page 7: Installation And Commissioning
All external cables should be installed safely to avoid mechanical damages. FAA-28 instruments are very low level signal measuring instruments. To avoid electrical noise, FAA-28 should be separated from the equipments that produce electrical noise. Preferable use metal cabinet against radio frequency interference and the cabinet shall be connected to ground against the electromagnetic disturbances. -

Page 10: Changing The Analogue Output
Changing the Analogue Output FAA-28 sets its analog output according to the table below at power on. Turn the programming switch and connect TxD and RxD pins as indicated in the table below before power on the instrument to set analog output type and its signal level. -
Page 11: Adjustments
• Connect the measurement instrument (Multimeter is recommended) to the analog output • Load the scale with a known load • The analog output value should be calculated for the applied load FAA-28, Technical Manual, Rev.1.1.0 February 2022 Page 10 of 21... - Page 12 The instrument saves 4 different adjustments in its memory for the voltage and current outputs and their ranges. Changing the analog output type it automatically set the adjustment to the output range used before. FAA-28, Technical Manual, Rev.1.1.0 February 2022 Page 11 of 21...

Page 13: Fast Adjustment To Nominal Output Range
Due to the production process of FAA-28, eCal accuracy is very high. Adjustment with eCal is performed via RS232 port of the instrument and can be comfortable executed with xFace software. -
Page 14: Adjustment (Ecal) With Plc
FAA-28 can be electronically calibrated via RS232C serial interface by commands or by xFace software. If you want to use your own software to calibrate the FAA-28 from your PLC or PC, you may use the commands below. The yellow colored bytes are the data in the command and blue colored bytes are check sum in this document. - Page 15 Stop the eCal process Response: @011000000001EE 3.

Page 16: Testing The Scale Performance
Testing the Scale Performance You have to check the scale performance by testing the scale eccentricity, scale linearity at loading up to maximum loading value, repeatability etc. before using it. FAA-28, Technical Manual, Rev.1.1.0 February 2022 Page 15 of 21... -
Page 17: Setpoints
5. Setpoints Setpoint Connection FAA-28 has 2 free relay contact output. These outputs can be connected to maximum 230VAC or maximum 30VDC, maximum 1A loads. Reverse diode connection to the DC loads is recommended to increase the relay contact life and to reduce the disturbances. -
Page 18: Operation Mode
6. Operation Mode There are 3 LEDs and 2 rotary switches on the front panel of FAA-28. The rotary switches are being used for adjustment as described in chapter 4.4 and the LEDs have different meanings in operation and setup type as indicated below. -
Page 19: Programming With Xface Software Over Rs232
7. Programming With xFace Software Over RS232 FAA-28 has RS232C serial interface to perform eCal electronic calibration and to adjust filter, setpoint values and to follow status by using xFace software installed on a PC. For installing the xFace software, which is supplied with the instrument or can be downloaded from www.flintec.com, follow the steps described below. - Page 20 12. Power on the instrument for operation. After performing eCal as described in the software, check the performance of your system. You may adjust to instrument to factory default by xFace, if it is changed before. FAA-28, Technical Manual, Rev.1.1.0 February 2022 Page 19 of 21...

Page 21: Trouble Shooting
8. Trouble Shooting The type FAA-28 amplifier is designed as a very reliable and virtually error free instrument. However, if an error occurs, do not attempt to repair the equipment before you understand what caused the error. Note the status of the front panel LEDs, and try to find the problem with the help of the table given below. - Page 22 Flintec GmbH Bemannsbruch 9 74909 Meckesheim GERMANY www.flintec.com FAA-28, Technical Manual, Rev.1.1.0 February 2022 Page 21 of 21...
