FEEDBACK MODES
There are two feedback modes for the VPIF, “Local
Display Only” or “Local Display and Remote Feedback”.
To change the setting, the VPIF must be opened and
manually set to the proper system requirements.
Improper settings can result in damage to the system
controller and/or VPIF.
The VPIF is shipped from the factor y with the jumper
in the “Local Display and Remote Feedback” mode.
1)
Local Display Only -
This mode is used when the
controller is not equipped with a valve position
display. The VPIF always displays valve position
in the AUTO, OPEN or CLOSE switch positions.
(Jumper on pins 1 and 2).
3)
Local Display and Remote Feedback
– With
switch in AUTO, valve position is read at both
the VPIF and controller (with valve position
display). With switch in OPEN or CLOSE
position, valve position is displayed on both the
VPIF
and
customer or Hansen controllers with
valve position display. (No jumper connection
standard. Place jumper on one post for future
use).
