8.6.3 Input Status
The Input Status menus allow the level of the logical input to be measured and
allow the action of the input to be enabled and disabled as far as the events

disabled, it will not cause an event warning or fault to occur. Enter the Input
status menus from the Valve test menus by pressing the UP button.
