This input is used for the FC control. It is possible to switch
from Volt to Ampère using mode switch 4.
This output can be used for connecting a potentiometer, with a load of 10V and 10mA.
The relay is switched as break contact and is activated when the FC is in the fault mode.
The relay is switched as make contact and is activated when the FC is in the operating mode.
