All external cables should be installed safely to avoid mechanical damages. FAA-27 instruments are very low level signal measuring instruments. To avoid electrical noise, FAA-27 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.
Only one of the analog output types can be used at the same time and has to be selected in the setup type. Install the analog output measuring instrument for adjustment, if need be. FAA-27, Technical Manual, Rev. 1.1, June 2014 Page 8 of 21...
Voltage output connection Changing the Analogue Output FAA-27 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.
Check the analogue output set up described in chapter 4.4. The analogue output cabling should be done for the same analogue output type. The adjustment (Adj) rotary switch shall be at “0“ - position. FAA-27, Technical Manual, Rev. 1.1, June 2014 Page 10 of 21...
G position to start gain adjustment. Gain Adjustment Connect the measurement instrument to the analog output. Load the scale. The analog output value should be calculated for the applied load. FAA-27, Technical Manual, Rev. 1.1, June 2014 Page 11 of 21...

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-27, Technical Manual, Rev. 1.1, June 2014 Page 12 of 21...
Due to the production process of FAA-27, eCal accuracy is very high. Adjustment with eCal is performed via RS232 port of the instrument and can be comfortable executed with xFace software.
FAA-27 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-27 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.

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-27, Technical Manual, Rev. 1.1, June 2014 Page 16 of 21...
6. Setpoints Setpoint Connection FAA-27 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.
7. Operation There are 3 LEDs and 2 rotary switches on the front panel of FAA-27. 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.
8. Programming With xFace Software Over RS232 FAA-27 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.

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-27, Technical Manual, Rev. 1.1, June 2014 Page 20 of 21...
9. Trouble Shooting The type FAA-27 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.
