Advanced Function Setting Level Section 5-7
• 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
parameter.
• The automatic display return time is disabled when the parameter is set to
OFF. (In that case, the display will not be automatically switched.)
• 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, how-
ever, by switching to the initial setting level, communications setting level,
or advanced function setting 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.
