3.5
Booster(s) Not Properly Tuned
Pneumatic volume boosters should always be equipped with a bypass needle valve. This
needle valve can be external or integral to the booster housing. Needle valve adjustments
are necessary to achieve proper valve response.
● If PS2 is in Auto and currently operating the valve:
– Rotate the needle valve counter-clockwise to slowdown response and reduce
overshoots.
– Rotate the needle valve clockwise to increase valve response
– Re-initialize PS2 after any needle valve adjustments; see Initialization Procedure
(Page 50)(see Appendix).
● A volume booster must be setup BEFORE initializing a valve positioner. The P-manual
mode ("NOINI" flashing), see display example below, can be used to perform this setup.
The P-manual mode will appear once proper electrical power is applied to a new PS2
valve positioner.
● If PS2 is currently initialized, activate "NOINI" mode:
– Press and hold
button to enter configuration mode
– Configuration parameter number appears in lower left corner of display.
– Use
button to reach parameter: "4 INITA".Press and hold button until "no"
appears on top of display.
– Press and hold
button to exit configuration mode
– Display will be similar to the following (numerical value will vary).
