BASIC OPERATION
2.
Select whether to lock out the front panel from making set-point transfers,
whether transitions are allowed between local and remote set-points, and
the digital input action (DIRECT or REVERSE).
3.
Choose which set-points to select between in the digital set-point
selection list (e.g., LOC, LO2). Refer to Table 3 for information on the DIG
INPT MENU.
4.
Enable the digital input in the DISPLAYS MENU.
A transition in the digital input state (opened to closed, or closed to opened)
will now cause a set-point transfer. For example, if a digital input is set up for
set-point selection between LOC and LO2 (using DIRECT action), a state
change of the digital input from closed to opened will cause a transfer to LO2,
and a change from opened to closed will cause a set-point transfer to LOC.
Similarly, if the digital input is set up for set-point selection between a local
set-point and a remote set-point, changing the digital input state will cause a
set-point transfer between local and remote.
