Applicability of manual
The following instructions are applicable to the maintenance
and installation of the Flowserve Logix 3800JF and JetFlow
Relay. The Logix 3800JF is an integral piece of the Logix
product platform, designed specifically for applications that
require speed and control of large volumes of air, such as
anti-surge prevention applications.
NOTE:
The Logix 3800JF utilizes a similar design layout
and functionality as the Logix 3800, consequently this
manual may act in part as an addendum to the
Logix™ 3800
Digital Positioner IOM FCD LGENIM0112.

Safety
CAUTION:
Before installation, read all safety related
information in section 2 Safety Information.
1.4
Disclaimer
These instructions cannot claim to cover all details of all
possible product variations, nor can they provide information
for every possible example of installation, operation, or
maintenance. This means that the instructions normally
include only the directions to be followed by qualified
personal using the product for its defined purpose. If there
are any uncertainties in this respect, particularly in the event
of missing product-related information, clarification must be
obtained via the appropriate Flowserve sales office. All

Installation
MOUNTING
Securely mount the JetFlow positioner unit to the bracket
attached to the actuator by using the bolt pattern on the back
of the JetFlow. See section 4, Installation
– Mounting, for
more detail.
FEEDBACK
The JetFlow positioner unit receives actuator position
feedback from a remote mount module. Check the feedback
linkage is connected and the follower arm is aligned to freely
move within the expected range of valve travel. Wire the
remote mount leads to the positioner terminals. Refer to the
Logix™ 3800 Digital Positioner FCD LGENIM0112
for
instruction on how to wire the remote mount module and
positioner.
PNEUMATIC CONNECTIONS
Verify the positioner is pneumatically connected to the
JetFlow. Connect the JetFlow pneumatic ports to the
actuator. Port A is typically connected to the side of the
actuator opposing the actuator spring, while port B is typically
connected to the side of the actuator to align with the action
of the actuator spring. See section 5, Installation - Tubing, for
more detail.
CAUTION:
Connecting the supply air may cause the
valve to move. Before connecting supply air, ensure the
valve is isolated.
ELECTRICAL CONNECTIONS
CAUTION:
Connecting the 4-20 mA signal may cause the
valve to move. Before connecting electrical signal, ensure the
valve is isolated.
Refer to the
Logix™ 3800 Digital Positioner FCD
LGENIM0112
for instruction on how to wire the positioner.
1.6
Configuration
The JetFlow positioner control software is configured at the
factory prior to shipment. Factory configured settings are
saved for the life of the positioner and will not be affected by
a factory reset.
1.7
Calibration
CAUTION:
During the QUICK-CAL operation the valve
may stroke unexpectedly. Notify proper personnel that the
valve will stroke, and make sure the valve is properly
isolated.
QUICK-CAL
The QUICK-CAL
button is used to initiate an automatic
stroke calibration. This stroke calibration determines the
closed (0%) and open (100%) positions of the valve and
gathers information about the response of the valve to
determine the control gains. The gains are automatically set.
After a QUICK-CAL calibration, the positioner is ready to
control.
To perform a QUICK-CAL, press and hold the QUICK-CAL
button for approximately 3 seconds, then release.
During the calibration, the LED lights will flash Yellow-Red-
Yellow-Green indicating the calibration is in progress. After
the calibration is complete, the LED lights should flash
Green-Green-Green-Green indicating a successful
calibration.
NOTE:
This first time the QUICK-CAL is performed, the
positioner will also complete a Full Calibration. This will
extend the time required for the calibration. This happens
with Standard and Pro diagnostic levels.
GAIN SWITCH
After the calibration, (and at any time during operation), fine
tune the gains by adjusting the Selectable GAIN Switch.
Selecting “A” through “D” will provide a more stable or slower
response.
Selecting “F” through “J” will provide a more active
or quicker response.
The “E” position is the default and is
typically more stable.
