Installation check
Check the construction of the control panel and the FA-M3
installation. Check the installation of the individual modules.
Check cables to ensure that all cables are properly routed and
connected to meet the wiring specifications.
The FA-M3 is a delicate electronic device. Special care must be taken
to avoid damage to the device when checking the insulation of the
machine or facility that uses this device.
Before turning on the power, measure the supply voltage to ensure
that it conforms to the given specifications.
There are two ways to check the external wiring: by using a multimeter
to examine the cables one at a time, or by actually turning the power
on and looking for problems. The latter method may be hazardous for
safety reasons and, therefore, require adequate care.
Start the test by checking the operation of safety circuits such as
emergency-stop circuits and protective circuits which are actuated
when the device gets into trouble.
Test each operating mode by stepping through the machine or facility
with push buttons.
Run each of specific blocks of the machine or facility in the automatic
mode or run a standalone test on the machine or facility in the
automatic mode. Then, proceed to full automatic operation of the
entire system.
Test to make sure that safety circuits actuates and reset normally
when anomalies occur in the machine or facility.
Before turning on the power, take all possible measures to minimize
any damage that might result from faulty wiring. Then, turn the power
on and check for problems.
