    7. INSTALLATION MGP146 GATE POSITIONER – 7. Installation 7.1. Mounting Do not use a rigid connection between the Controller’s operator shaft and the position translator. Doing so risks damaging the DIP seal which can lead to fire or explosion. Use U-bolts to mount the Controller with the operator shaft connected, and a flexible linkage to the slide gate. Use a helical coupling for direct drive from a gates rack position translator, or chain drive hooked to the sprocket gear to translate linear displacement.

  • Page 28: Controller Parameters

    8. CONTROLLER PARAMETERS MGP146 GATE POSITIONER – 8. Controller Parameters The operation and accuracy of the Controller is determined by user configurable parameters. This section describes each of these parameters and the effect they have on the operation of the Controller.

  • Page 29: Communication Port

    MGP146 GATE POSITIONER – 8. CONTROLLER PARAMETERS 8.3. Communication Port 8.3.1 Serial Port Speed [Register 48] The communication port can operate at five standard baud rates. The Controller only determines its baud rate during a power-up sequence and must be reset for a new baud rate to take effect. Cycling power or issuing a Soft Reset over the communication system will reset the Controller.

    8. CONTROLLER PARAMETERS MGP146 GATE POSITIONER – 8.4.3 Encoder Direction [Register 44, Options 1, 2, 3, and 4] Selecting the CCW option can change direction of rotation interpreted by the magnetic encoder. Note the open and close outputs and limit switches must be wired to reflect the direction of rotation. The default is CW (clockwise) as opposed to CCW (counter-Clockwise).

  • Page 31: Pseudo Limit Switch System

    MGP146 GATE POSITIONER – 8. CONTROLLER PARAMETERS 8.5.2 Pseudo Limit Switch System The Pseudo Limit Switch system allows for the creation of open and closed limit switches using the transducer position value. This system cannot be used to substitute for a closed limit switch for multi-turn applications. In all other cases the Pseudo Limit Switch will emulate the limit switch functions available to an input limit switch.

  • Page 32: Positioning Accuracy

    8. CONTROLLER PARAMETERS MGP146 GATE POSITIONER – 8.7. Positioning Accuracy The following parameters determine the accuracy of the final position achieved by the Controller. These parameters should be configured before an automatic calibration sequence is initiated. The Controller uses a two-step process to position the actuator: 1.
  • Page 33 MGP146 GATE POSITIONER – 8. CONTROLLER PARAMETERS Table 8 Position Accuracy Parameters (continued) Parameter Description must be longer than or equal to the Turn Around Time parameter. The default value is 20 for 2000 milliseconds. After each jog the Controller adjusts the jog on time. This value is the Minimum Jog on Time (Lit) [Register 40034] shortest jog on time the Controller will allow.

  • Page 34: Calibration Parameters

    8. CONTROLLER PARAMETERS MGP146 GATE POSITIONER – 8.7.1 Calibration Parameters The Controller can perform an automatic calibration sequence. This sequence automatically sets the Controller’s calibration parameters. See Section 9. – Calibration on page 36 for details on initiating a calibration sequence.

  • Page 35: Timing

    MGP146 GATE POSITIONER – 8. CONTROLLER PARAMETERS 8.8. Timing The controller uses a series of timers during a positioning operation: Parameter Description Output Turn Around Time Most Actuators require a delay between open and close operations. The [Register 40027] turnaround timer forces a delay between all operations. Anytime an output is turned off, both outputs will remain off until this timer has expired.
