7.3 Clearing a Mismatch Fault Indication
In all cases the fact that a Mismatch Fault has been indicated warns users that the safety of the
system may be compromised. Site-specific instructions should indicate the actions to be taken by
users in such an event.
Depending on the internal settings made above, the system may or may not be temporarily cleared
by turning the mains switch off, waiting for ten seconds, then turning it back on again. In this case
the system should be attended to by a suitably qualified technician to identify and repair the fault at
the earliest opportunity.
If the ICS-6 has been configured to permanently lock out, it can only be reset by opening the unit,
turning on the power and pressing the ‘RESET’ button SW1 on the Control Board. This should only be
undertaken by suitably qualified technicians once the fault has been identified and repaired as
otherwise the unit will just lock out again.
