The signals coming from the control card are of "NPN" type, actives when ground
directed. The function of the relay RL7 ("SAF" on the silk-screening) is to protect the
personnel: it breaks the common power supply of the power contactors, That are
supplied only when all the safety micro-switches are closed.
To protect the card is selected a FS1 fuse of the type 30x38 of 10A.
The turn on of the DL8 led indicates the fault of the FS1 fuse. This interface is connected
to the local unit control through the CN18-CN1 connector.
