11.4 Mismatch Indication and Reset

All  the  safety  circuits  are  dual  channel  with  mismatch  detection.  If  their  states  differ  there  is  a
mismatch condition, indicating a fault somewhere in the circuit. For instance, one contact of a door
switch may not be closing. If this occurs, a fault condition will be indicated, and the fault condition
will be latched until reset.

Note that  a short  period of  mismatch is  allowed  by  the interlock controller,  because  two switches
will never close at exactly the same time.

The mismatch is indicated by an icon on the display, and a touch button is provided to reset the fault
condition after  the  fault has been rectified. Touching  the  button  sends a message to the  ICS-6-SP,
which then attempts to reset the fault latch. If the fault no longer exists, this will succeed.
