  • Page 20: Operation Modes

    Lufkin Well Manager™ 2.0 Rod Pump Controller User Manual Operation Modes The LWM 2.0 controller has three rod pump control operation modes: • Host: The controller starts and stops the pumping unit based on a user command. This mode is primarily intended for use with a SCADA system. A Host Mode Off global command can be issued by the SCADA program to shut down specific wells and keep them shut down until the operator decides to re-start them.
  • Page 21 System Overview Pump Off Control Actions When a pumped off condition is detected, the LWM 2.0 controller is capable of cycling off the well as needed. Downtime can be programmed by the operator based on experience or production tests. Load and Position Input Options The LWM 2.0 controller is designed to accept load and position data from a number of input devices.

  • Page 22: Communication Protocol

    Communication Protocol The LWM 2.0 RPC uses Modbus-based communications protocol, and also offers the advantages of the Extended Lufkin Automation Modbus (ELAM) protocol for SCADA software packages that goes beyond the limitations of conventional Modbus. All of the configuration, status, and historical data available at the local keypad interface are also available via data telemetry link to SCADA software.

    Lufkin Well Manager™ 2.0 Rod Pump Controller User Manual Setpoint Violations and Malfunctions The LWM 2.0 controller is programmed with a series of setpoints that determine how the controller reacts to situations that occur during pumping operation. The following is a list of setpoint violations that can occur: •...

    Lufkin Well Manager™ 2.0 Rod Pump Controller User Manual • Signal Voltage: The differential load signal is connected to terminals 2 and 3 on Terminal Block 1 (TB1). Terminal 2 should be a few MVDC positive with respect to terminal 3. The magnitude of the signal depends on the type of load device used.

    Troubleshooting For both types of load devices, each wire to earth ground should read greater than 10 M. Note: It is best to make these measurements with the pumping unit in operation, since cable problems may be intermittent and show up at only a certain point in the stroke as the cable flexes.

    Appendix Overview This appendix describes the theory behind the Lufkin Well Test (LWT) feature that is used for calculating pump intake pressure and fluid production through the pump. Overview of PIP and LWT Lufkin Well Manager 2.0 controllers offer a Pump Intake Pressure (PIP) feature. This feature has an algorithm that can determine the pump fluid load by analyzing the downhole pump card.
