The table below shows that Digital Input 3 is defaulted to be used for the Dual Setpoint Function
Parameter Name
76.11 DI3
EXAMPLE: Process Control PID with the primary 4- 20 mA Transmitter wired to AI1 with the primary set
point, which can be varied wired to AI2. Either Analog Input can be either Current or voltage.
Parameter Name
76.01 AI1 CONFIG
76.02 AI2 CONFIG
Note: The effect is a straight relationship with the maximum set-point value corresponds to the
maximum signal [i.e. 20 mA or 10 VDC] while the minimum set-point value corresponds to the
minimum signal [0/4mA or 0/2 VDC].
Value/Range Notes
DUAL STPT SEL This is the Default setting for this parameter. This selection will use
setup digital input DI3 to toggle between set-point 1 and set-point
2. DI3 low is Setpoint 1; DI3 High is Setpoint2. Any available DI can
be used for this function. DI3 is the default.
For Multipump this MUST BE WRIED IN SERIES between all drives.
Value/Range
