FOR ROTARY VALVES:

For Rotary Valve applications with 90° travel, use the '+' & '-' keys to move
the valve to the mid-point of its stroke. Use the Travel Indicator of your
Actuator to achieve this. Next, use the Sliding Clutch to set the Position
Display of the positioner to read as close to '50' as possible, don't worry if it is
out a little bit. Stroke the valve to each Travel Limit and ensure your display
reads close to '0' at one limit, and close to '100' at the other. It does not
matter which is open and which is closed at this point as the display can be
changed to read correctly in Parameter 38. Refer to page 25, Step 12, Section
"d", Note "i" of this Guide.
9 Once the Sliding Clutch is set, lock it by tightening the Sliding Clutch Lock with
a small screwdriver. It is the yellow wheel under the Sliding Clutch. Refer to
Figure 15, Page 34, rotate clockwise to lock it. Access to the Class I Zone I
Clutch Lock is inside the positioner. It is a yellow wheel in the middle of the
Positioner and can be adjusted by using a small screwdriver (Figure 16).
10 Note: The 'HAND' Key function (Figure 10)
a One press takes you from Auto Mode to Manual Mode and Manual Mode to
Auto Mode (as indicted by the display on the readout).
b To enter Programming Mode, fi rst make sure you are in Manual Mode then
press and hold the 'HAND' Key for 5 seconds.
11 When in Programming Mode, scroll through the Parameters by briefl y hitting
the 'HAND' Key. Change the Parameter values by hitting the '+' & '-' Keys.
12 While in Programming Mode, change the following Parameters (refer to
attached Parameter List (Figure 14) for brief explanation of parameters, refer
to Chapter 9 of the SIPART PS2 Operation, chapter on Commissioning):
a Parameter 1: WAY.
LINEAR MOUNTING KIT (Refer to Page 8) Parameter 1 will need to be set
to FWAY.
b Parameter 2: 90 or 33 for Step 5.
c Parameter 7: Set to RISE or FALL depending on your valve:
i Note: For Rotary Valves, if Potentiometer is rotating clockwise when
actuator begins to stroke (increasing the signal to diaphragm), this
will be FALL, counter clockwise: RISE.
ii For sliding stem RISE for fail closed, FALL for fail open.
d Parameter 38: RISE or FALL, make it the same as Parameter 7
i Note: This parameter merely determines the display when the valve
strokes (0-100%). If for some reason the display shows 100% when
the valve is closed and you want it to read 0%, just change this
parameter.
e Parameter 39: UP DO.
