 +==== Interlock Open ====
 If either the key switch is deactivated or the interlock is opened while the system is operating, the SLICE-DCC will stop delivering current and the Enable window will flash red with INTERLOCK displayed (<imgref inter_open>). In order to resume normal operation, interlocks must be restored to their operational state and the window must be touched to reset the tripped interlock. \\  If either the key switch is deactivated or the interlock is opened while the system is operating, the SLICE-DCC will stop delivering current and the Enable window will flash red with INTERLOCK displayed (<imgref inter_open>).

 If the SLICE-DCC attempts to deliver current, but is unable to do so, it assumes an open circuit fault.  The Enable window on the Home screen for that channel will flash red with the warning "Open Circuit/Over Voltage" (<imgref open>). If the SLICE-DCC attempts to deliver current, but is unable to do so, it assumes an open circuit fault.  The Enable window on the Home screen for that channel will flash red with the warning "Open Circuit/Over Voltage" (<imgref open>).
