After activating START, if no interlocked conditions are
present, the “ENABLE” led is lit on M320. Within 10 seconds
from the start, the filament voltage limitation relay is switched:
the MWON led is fully lit and the filament voltage drops to an
appropriate value.
NOTES:
· When START is activated, no energy is supplied if any of
the breakdowns mentioned above occurs.
· Do not continue pressing the START key if you do not
obtain any result. Search the cause of the breakdown.
· Never use a permanent-contact switch instead of the
START button, otherwise the interventions of the safety
mechanisms are cancelled.
· Before removing the M320 card, turn off the power by
opening the external switch.
· Never remove the M320 card from the guides during the
operation, even if it is set to STOP.
·Always open the external switch before replacing the fuse
or making connections to the power supply unit.
