Quick Start Instructions
The DIP switch settings and Quick-Cal function listed below
are typically all that are needed to calibrate and tune the
positioner for use. This simple procedure takes only seconds
for most valves.
1
Using the Configuration Switches, select the desired
configuration. See section 8.3 Configuration Switch
Settings for details.
2
Hold the Quick-Cal button for 3 seconds. This will
initiate a stroke calibration.
3
After the stroke calibration is complete, the positioner is
ready for control.
WARNING: 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.

Local User Interface Overview
The Logix 3200MD local user interface allows the user to
calibrate, configure the basic operation, and tune the
response of the positioner without additional tools or
configurators. The Local interface consists of:
•
Configuration Switches (8) – Used to set basic
configuration. See explanations in section 8.3
Configuration Switch Settings.
•
Interface Buttons – Used to calibrate the positioner,
perform special functions and navigate the display
menu.

Configuration Switch Settings
Before placing the unit in service, set the Configuration
Switches to the desired control options.
NOTE: The Configuration Switch settings are activated
only by performing a Stroke calibration (pressing the
“QUICK-CAL” button for 3 seconds). However, the
Configuration Switch settings may be edited from the DTM or
Handheld at any time.
8.3.1
Air Action Switch
This must be set to match the configuration of the
valve/actuator mechanical tubing connection since the tubing
determines the air action of the system.
If Single Acting (Poppet) Relay
ATO - Increasing pressure from Port B (labeled “Y1”) causes
the valve to open.
ATC - Increasing pressure from Port B (labeled “Y1”) causes
the valve to close.
If Double Acting (Spool) Relay
ATO - Increasing pressure from Port A (labeled “Y1”) causes
the valve to open.
ATC - Increasing pressure from Port A (labeled “Y1”) causes
the valve to close.
8.3.2
Valve Action Switch
This must be set to match the configuration of the actuator
and is used in some diagnostics.
Double - Select Double when both sides of the actuator are
pressurized.
