• Measure output contacts using the voltage drop method of applying at least the minimum
contact load given for the output relays in the technical data, for example 100 mA at 24 V
AC/DC.

Change the parameter
3PhaseAnalogGroup/SMAI_20_n:1 (n= the number of the SMAI used).
Changing the
skills.
Change the parameter in PCM600, see PCM600 documentation.
In LHMI, select Main menu/Tests/I/O modules. Then navigate to the board with the
actual binary input to be checked.
Check the actual state of the connected binary inputs through PCM600, see PCM600
documentation.
Output relays, especially power output relays, are designed for breaking high
currents. Due to this, layers of high resistance may appear on the surface of
the contacts. Do not determine proper functionality of connectivity or contact
resistance by measuring with a regular hand-held ohm meter.
