For maintenance purposes, an interlock override function has been implemented. This func-
tion makes it possible to operate the ILS locally in manual mode with an active interlock sig-
nal. To activate the interlock override function the following conditions must be met:
• LOCAL/REMOTE switch must be in LOCAL position,
• AUTO/MANUAL switch must be in MANUAL position and
• INTERLOCK OVERRIDE switchlock must be set in horizontal position.
The remote control will always be set in ALARM state when the interlock override function is
activated.
