To prevent the mismatch detector from being reset by cycling the power i.e. to require the detector
to be reset by a technician, remove the link ‘Auto RST’.
Note that when the link ‘Auto RST’ is fitted, the power to the ICS-6-SP Control Unit must be turned
off for at least 10 seconds to reset the detector and clear the indication.
The Mismatch Detector is enabled by default. To disable the mismatch detector, close the link
labelled ‘Disable’.
Carefully clip the cover back into place once any adjustments have been made.
8.2 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.
If the auto reset option has been selected, the system may be temporarily cleared by turning the
power supply 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 as a fault has been identified and the system may cease to provide protection without
further warning.
If the ICS-6-SP Control Unit has been configured to permanently lock out, it can only be reset by
pressing the Mismatch Reset button using a suitable tool through the hole in the cover as shown in
the previous section above. 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.
