MVP-R Ramping Controller Welcome Welcome to High Country Tek Inc. HCT is North America’s foremost independent designer and producer of modular, ruggedized digital and analog electronic controllers for the fluid power industry. From our factory in California, we manufacture ‘specialty’ controllers for specific functions and the user programmable ‘DVC family’ to enable large area networked system solutions. The modules are used in mobile, industrial and marine applications.
MVP-R Ramping Controller Product Application Guidelines ALWAYS do the following FULLY read this manual and accompanying data sheets BEFORE starting. Isolate this unit from all other equipment BEFORE any form of welding. Isolate the controller from ANY form of battery charging or battery boosting. Be aware of the electrical & mechanical connections, and the expected reactions of the equipment. Operate the units within the temperature range. Use the correct tools to do the job (i.e. P.
MVP-R Ramping Controller MVP-R Ramping Controller The MVP-R controller drives proportional solenoid valves with adjustable ramp times. Once configured, the settings are permanently stored in the controller memory.
MVP-R Ramping Controller Physical Description There are two indicator LEDs: STATUS and OUTPUT. The STATUS LED is green when the applied voltage is within the operating range. The OUTPUT LED is yellow and the brightness will vary with the output current. In the case of a fault the STATUS LED will flash red with a flash code. See Fault Status for details. The MVP communicates with the Graphical User Interface through an infrared interface port to RS232.
MVP-R Ramping Controller Configuration The GUI has 4 buttons (ran from a PC): Lock, Unlock, Up, and Down. There are short-cut keys: ‘/’(lock), ‘*’(unlock), ‘+’(up), and ‘-‘(down). The HCT Hand Held Interface has the same 4 buttons and 2-line LCD. Use the up and down arrows to navigate through the parameter list. The display will show the next parameter in the list when pressed. The parameter name is on the first line and the value is on the second line.
MVP-R Ramping Controller “Read settings from controller” displays a static table of values from non-volatile memory. The changes made to the settings by selecting “lock” are not updated in the table unless “read settings from controller” is selected again. To save the settings into a file for future use, click “read settings from controller” before clicking “save settings to file”. 021-MVP-R Rev A MVP-R User Manual Copyright © High Country Tek, Inc.
MVP-R Ramping Controller When uploading settings from a data file, the static table shows the settings from the data file, but they are not in the controller yet. Click “write settings to controller” before clicking “read settings from controller”. After this step, the static table displays the MVP settings from the data file. 021-MVP-R Rev A MVP-R User Manual Copyright © High Country Tek, Inc.
MVP-R Ramping Controller Parameter List The following table outlines the MVP-R parameters as well as the limits and units of measure for each parameter. Parameter Limits Units MVP-RPx-xxx Version # Ramp time factor X1, /10 Mode # Ramp up time 0.0 to 120.0 Seconds 0.0 to 120.0 Seconds Ramp down time * 0 to 600 ** mA Maximum output 0 to 600 ** mA Dither frequency 80 to 300, Minimum output Hz.
MVP-R Ramping Controller MVP-RPx-xxx - The title parameter is fixed. It displays the model number and the firmware version. RAMP TIME FACTOR – Sets the rate of change for the output current. If the Ramp Time Factor is x1, the ramp time will match the ramp time settings. If it is set to 1/10, the ramp time will be 1/10 of the ramp time setting. RAMP UP/DOWN TIME - Sets the rate of change for Output current. For RP1, the output current increases from Minimum to Maximum.
