Detailed Product Description

Original Usa Flowserve Logix 3200Md Digital Positioner 3200Md

 

The Logix 3200MD digital positioner is a two-wire 4-20 mA input digital valve positioner. The positioner is configurable through the local user interface. The Logix 3200MD utilizes the HART protocol to allow two-way remote communications with the positioner. The Logix 3200MD positioner can control both double- and single-acting actuators with linear or rotary mountings. The positioner is completely powered by the 4-20 mA input signal. Start up current must be at least 3.6 mA without AO card or 3.85 mA with AO card.

The Logix 3200MD positioner is an electric feedback instrument. Figure 1 shows a Logix 3200MD positioner installed on a double-acting linear actuator for air-to-open action. The Logix 3200MD receives power from the two-wire, 4-20 mA input signal. However, since this positioner utilizes HART communications, two sources can be used for the command signal: Analog and Digital. In Analog source, the 4-20 mA signal is used for the command source. In Digital source, the level of the input 4-20 mA signal is ignored and a digital signal, sent via HART, is used as the command source. The command source can be accessed with ValveSight software, the HART 375 communicator, or other host software. Whether in Analog or Digital Source, 0% is always defined as the valve closed position and 100% is always defined as the valve open position. In Analog Source, the 4-20 mA signal is converted to a percentage. During loop calibration, the signals corresponding to 0% and 100% are defined.

 

A more detailed example explains the control function. Assume the unit is configured as follows:

• Unit is in Analog command source.

• Custom characterization is disabled (therefore characterization is Linear).

• No soft limits enabled. No MPC set.

• Valve has zero deviation with a present input signal of 12 mA.

• Loop calibration: 4 mA = 0% command, 20 mA = 100% command.

• Actuator is tubed and positioner is configured air-to-open

 

 

Note: The air supply must conform to ISA Standard ISA 7.0.01 (a dew point at least 18 degrees Fahrenheit below ambient temperature, particle size below five microns—one micron recommended—and oil content not to exceed one part per million).
