    Introduction This manual explains the installation and use of the evc/epc Digital Controllers. Users need to understand the hazards in an electromechanical environment. Read this entire manual before installation. Pay particular attention to caution and safety information.

  • Page 5: Product Application Guidelines

    The GUI and controller software give the user flexibility and ease of use, even for novice users.  The GUI is not intended to be connected to a non-evc/epc unit. Care must be taken to use the correct GUI and hardware combination. After program entries, cycle the power to ensure changes are accepted by the unit.

  • Page 8: Using The Evc/Epc With Your Pc

    System Requirements Windows XP, Vista or Windows7, 100MB or greater free disk space.  Insert the CD into the PC drive and follow the on-screen instructions. This will install the evc/epc GUI, manual and help files.  Install the Com Port drivers for the evc/epc.
  • Page 9 At start up the GUI searches the PC com ports for the evc/epc controller. The default MAC ID is 1. If the evc/epc has been programmed with a different Mac ID, you can search for the controller by “Find Module” or enter the Mac ID. The “Find Module” will restart the operation when the unit responds with its information and Mac ID.

    Restore unit to last permanent settings saved: Reload RAM with settings stored in the EEPROM. This will undo all changes made since the last Permanent Save. Restore unit settings from data file (.dat): Load the data file from the PC to the evc/epc for different modes of operation.

    In the Automotive Environment, load control is called “Anti-Stall” and in the Agriculture environment the same function is called “HP Limiting”. Password     “Enter Password” unlocks certain features of the GUI. Passwords are ‘cAsE SeNsitivE’. 023-00354-Rev1.4 evc/epc User Manual Copyright © High Country Tek, Inc. – 2013...

  • Page 13: Data Logging

    Each log begins with a list of unit settings and is followed by real time operational information. The sample rate depends on the workload of the PC and the evc/epc at recording. A timestamp scales the logs appropriately. Subsequent logs may be stored in a new file or appended to the original log file by selecting the original file.

  • Page 17 When Current Feedback is “OFF”, the Coil A/B Min Current setting does not apply and is grayed out. The Max Current is used as a reference for the evc/epc to declare a coil short condition when the output current is 0.5A higher than the max setting.
  • Page 18 100%.  When Ignore Open is “OFF” and Current Feedback is “ON”, the evc/epc will declare an error when the output duty cycle reaches 100%.  When Current Feedback is “OFF”, Ignore Open does not have any impact.

  • Page 19: Manual Mode

     All settings on this tab are temporary and will immediately affect the outputs.  In manual mode all limits and controls are bypassed.  The evc/epc goes back to normal operation when exiting the GUI in manual mode.  Cycling power on the unit will reset the controller and remove manual override.

  • Page 20: Command & Error Settings

     To use this feature, the Analog Center Active has to be “ON”.  This safety feature ensures that the system will NOT immediately go to the previous settings after cycling the power. 023-00354-Rev1.4 evc/epc User Manual Copyright © High Country Tek, Inc. – 2013...

  • Page 28: Anti-Stall Or Horsepower Management With Fixed Command

     When the measured RPM starts to drop below the “RPM Slow”, Coil A current is reduced proportionally to the measured RPM.  Coil A current becomes zero when the measured RPM reaches “RPM Stop”. (1500RPM). 023-00354-Rev1.4 evc/epc User Manual Copyright © High Country Tek, Inc. – 2013...
  • Page 29  If the Reverse Retry Count is depleted and the measured RPM remains below RPM Stop, the evc/epc will declare an error.  At start-up the measured RPM must initially reach the “RPM Slow” to allow the evc/epc to ramp up Coil A. This ensures that the prime mover has started and is at a stable speed.
