Quick Start Guide

CTLS Issue 3
This guide covers only a brief description of installation and maintenance for
Spiratrol and QL valves. For detailed installation, operations, maintenance
including safety, precautions, and warnings, please refer to our official instruction
manual at www.spiraxsarco.com (IM-P704-02).
PP6 is Pneumatic-Pneumatic Positioner that accurately controls valve stroke in response to a pneumatic
input signal of 0.02~0.1 MPa (0.2~1 bar) from the controller.
! NOTE: Use of the positioner in a hazardous area.
1 The positioner must be suitably earthed to prevent static electricity
2 Operation with air hotter than 70 °C is to be avoided
3The positioner must not be used in a Zone 0 area.
4Only wipe the positioner with a damp cloth to prevent static build up.

1.1.2 Assemble the supplied feedback lever and
bracket to positioner firmly, then loosely
mount the assembly on the left hand side of
the actuator yoke. For central mount, mount
on the right hand side of the actuator yoke.
1.1.3 Make sure that Positioner’s feedback lever is
perpendicular to the valve stem at 50% of the
valve stroke.
1.1.4 The feedback pin coming from the actuator
coupling should be inserted inside slot of the
feedback lever in such a way that the length
of valve stroke coincides with the
corresponding figures in “mm” marked on the
feedback lever.
Improper setting may cause poor linearity or
damage to positioner.
1.1.5 At 0% or 100% position, the linear lever or
linear lever stopper should not touch the
stopping bosses of positioner.
1.1.6 As a final step, tighten the bracket to the
actuator yoke.

1.2 Rotary positioner
1.2 .1 There are three brackets in the positioner box.
1.2.2 Refer to the figure and check the bolting
positions of the upper and lower brackets to
be fastened depending on the actuator’s stem
height. And then assemble the positioner with
the brackets by using M6 bolts, washers and
nuts.
1.2.3 Make sure that the center of positioner's main
shaft is well aligned with the center of
actuator's stem.
1.2.4 Tighten the positioner and bracket, taking into
account the alignment described in step 3
above.

3. Adjustments
3.1 Adjustment - Zero Point
Set input signal pressure at 0.02MPa (or 0.1MPa)
as the initial signal and rotate the adjust wheel
of zero setting unit upward or downward to set
actuator’s zero point. Please refer to the gure
opposite.
3.2 Adjustment - Span
3. 2.1 After setting zero point, supply input signal
pressure at 0.1MPa (or 0.02MPa) as the
end point pressure and check the actuator
stroke. If the stroke is low, the span should
be stretched. If the stroke is high, the span
should be reduced.
3.2.2 Changing span will a󰀨ect zero point setting
so zero point should be set again after span
has been adjusted.
3.2.3 Above two steps are required several times
until both zero and span are properly set.
3.2.4 After proper setting, tighten lock screw of the
span unit.
3.3 Adjustment –
A/M switch (Auto/Manual)
3.3.1 Auto manual switch is located on the
top of pilot unit. Auto manual switch
allows the positioner to be functioned
as bypass.
If the switch is rotated counterclockwise
(toward “M”, Manual), then the supply
pressure will be directly supplied to the
actuator regardless of input signal. On
the other hand, if the switch is turned
clockwise (toward “A”, Auto), then the
positioner will operate normally by
input signal.
3.3.2 Make sure that the supply pressure
does not exceed the rated pressure
level of the actuator before the switch
is loosened toward “M”.
3.3.3 After using the “Manual” function,
return the auto manual switch to
“Auto”.
