P5 – SETPOINT OPTIONS
This register defines the output action for SetPoint and Current Loop models. Note that if an output is disabled by
this register, the SetPoint value in its corresponding register (P6, P7) has no impact. Also note that a SetPoint value
(P6, P7) may be 0.0, which is a viable output setting; thus, in order to disable control action, register P5 should be
used to define the desired action.
In Measure Mode, the indicators “SET1” and/or “SET2” will illuminate when the corresponding relay is energized.
The “4-20mA” indicator will illuminate when the Current Loop output is enabled. In Program Mode, the
indicators “SET1”, “SET2”, and “4-20mA” will illuminate as appropriate to assist when scrolling through the
register’s choices. Note that if P5 is set for active, the outputs will continue to update even in Program Mode,
according to the currently programmed values.
