<Causes>

1. Interlock is set for the switch.
2. ON delay is set for the switch. (TS/V8 only)
3. Touch switch position is deviated.
4. When the screen change switch (Function: Screen) is used, the "screen internal switching" bit is ON so screen switching is disabled.

1. Display the [Switch] dialog → [Other Settings] → [Interlock] and check if [Use interlock] is checked. If checked, satisfy the conditions set for interlock.
