• In the operation level or adjustment level, the display automatically returns
to the PV/SP if there are no key operations for the time set for this param-
eter.
• The automatic display return time is disabled when the parameter is set to
OFF. (In that case, the display will not be automatically switched.)
Setting range
OFF, 1 to 99 Second
• When a parameter is set to ON, once the alarm function has turned ON it
is held until the power is turned OFF. The latch can be canceled, however,
by switching to the initial setting level, communications setting level,
advanced function setting level, or calibration level.
• If alarm outputs are set to "close in alarm," the outputs are kept closed. If
they are set to "open in alarm," they are kept open.
