9.4.3.1. Ground faults. Normal
Ground faults in any control circuits operation a external status display lights up
must not result in unintentional startup, b green status display lights up
potentially hazardous motions or shutdown c red ground-fault indicator lights up
of the machine.
During normal operation the auxiliary circuit is
connected to the functional ground and the green
(24 - 48 V) or yellow (110 - 220 V) status display is
illuminated.
If a low resistance ground fault occurs, the line fuse
will blow.
Once the contact separator is open, you can replace
the fuse. Ground fault d external status display lights up
The illumination of the red lamp alone indicates an e green status display lights up
ground fault. f red ground-fault indicator lights up
After the fault had been rectified, the green
(24 - 48 V) or yellow (110 - 220 V) display will also light
up. The contacts should now be moved to the “on”
position as a result of which the red lamp will go out.
The illumination of the yellow or green lamp and
external display indicates that the auxiliary circuit
has been reconnected to the functional ground.
