Recommendations
Warning: Please care the following warnings for designing the control cabinet which
will increase your system reliability.
The control cabinet should be designed so that the instrument can operate safely.
The panel should be placed in clean area, not getting direct sun light if possible, with
a temperature between -10 ºC and +40 ºC, humidity not exceeding 85% non-
condensing. All external cables should be installed safely to avoid mechanical
damages.
FAA-26 instruments are very low level signal measuring instruments. To avoid
electrical noise, FAA-26 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. Load cell cable and analog output cable trays must be separated from
others, if possible. If there are noise-generating equipments such as heavy load
switches, motor control equipments, inductive loads etc., please be careful against
the EMC interference in the cabinet. Connect parallel reverse diodes to the DC
inductive loads like relays, solenoids etc. to minimize voltage peaks on the DC power
lines.
All load cell and analogue output cables coming to the control cabinet shall be
shielded.
Warning: Control cabinet design and proper installation increases reliability and
performance of the instrument. Please do not forget that the instrument must be
powered off before inserting or removing any peripheral connector.
Follow the installation and commissioning described below carefully to prevent
unwanted results after installation.
