SAUER-SUNDSTRAND-MCE123A-Auxiliary-Controller-fig-1

Specifications

  • Product Name : MCE123A Auxiliary Controller
  • Model Number : MCE123A1001, MCE123A1002
  • Supply Voltage: 24VDC
  • Frequency Range: 200Hz – 700Hz, 253Hz – 380Hz
  • Output Current: 60mA – 100mA, 30mA – 100mA

Product Description

The SAUER-SUNDSTRAND MCE123A Auxiliary Controller provides a reverse proportional control signal to the Electrical Displacement Control (EDC) in open loop. The output signal is proportional to the measured frequency input from a speed sensor, and it decreases with increasing speed.

Features

  • Proportional control signal
  • Reverse proportional output with speed increase
  • Designed for open-loop operation

Technical Data

  • Supply Voltage: 24VDC
  • Ripple: 20%
  • Output Current: See ordering information
  • Frequency Range: See ordering information

Theory of Operation

The MCE123A converts frequency signals to proportional DC voltage. The output current value is reverse proportional to the frequency signal based on an adjustable control characteristic.

Product Usage Instructions

  1. Connect the MCE123A Auxiliary Controller to the Electrical Displacement Control (EDC) using the provided connection diagram.
  2. Ensure the supply voltage is 24VDC.
  3. Adjust the control characteristic for the desired output current based on the frequency signal.
  4. Monitor the output signal to ensure it is reverse proportional to the frequency input from the speed sensor.

Frequently Asked Questions (FAQ)

  • Can I use a different supply voltage with the MCE123A Auxiliary Controller?
    No, the MCE123A requires a supply voltage of 24VDC for proper operation.

  • How do I adjust the control characteristic of the MCE123A?
    The control characteristic adjustment is detailed in the product manual. Refer to the manual for specific instructions.

DESCRIPTION

  • The SAUER-SUNDSTRAND MCE123A Auxiliary Controller provides, in open loop, a “reverse proportional” control signal to the Electrical Displacement Control (EDC). This signal is proportional to the measured frequency input to the Controller from a speed sensor.
  • The Controller is designed so that with increasing speed, the output is reduced

THEORY OF OPERATION

  • The electronic MCE123A converts the frequency signal to a proportional DC voltage.
  • Depending on an adjustable control characteristic (see figure 1) the output current value is “reverse proportional” to the frequency signal.
