HCT Introduction
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. They are also applied successfully in other
industry segments.
HCT products are encapsulated in solid flame resistant material for maximum durability, electrical integrity and
complete environmental security.
HCT is a market leader in many application arenas, including hydraulic generator, e-Fan and hydraulic fan system
controls. These controllers facilitate significant fuel, emission and operational savings.
HCT’s market neutrality offers integration with any hydraulic OEM valves, pumps, sub-systems or systems.

Cautions
Changing setup values or operating modes while a machine is running may cause unintended machine movement.
It could lead to possible injury or death. Any moving parts should be disabled prior to changing setup values or
operating modes. In every case, exercise caution and work should be completed only by qualified personnel.
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.C., software) etc.
•Separate High Voltage AC cables from Low Voltage DC signal and supply cables.
•Make sure power supply is CORRECT, ELECTRICALLY CLEAN, STABLE, and rated for the full load.
•Make sure the controller output voltage & current is compatible with the equipment.
•All unused wires / terminals should be terminated safely.
•Ensure ALL connectors have no unintended SHORT or OPEN circuits.
•Ensure ALL connectors are wired correctly, secure, locked in place and fully connected.
•Disconnect or connect wires to or from this unit only when the power supply is disconnected.
•Use adequate screening in areas of intense Radio Frequency fields.
•Ensure ALL work areas are clear of personnel before operating the 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. The infrared
adapter clips onto the MVP-R aligning with the notches in the sides. It must be powered when configuring the
settings.
User Interface
The MVP has a number of internal settings.
Users can open the Graphical User Interface to view, make changes and save the settings in a data file, which can
be uploaded to any MVP controller.

The users can use the Hand Held Interface to view and make changes, but can not save the settings in a data file.
The programmer, cable and adapter are self-contained which makes HHI a viable alternative for field work.
Configuration
The GUI has 4 buttons: 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 a 2-line LCD display.
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. The list scrolls,
stepping down from the last parameter to the first and vice-versa.
There are three types of parameters: fixed; monitor; and variable. Fixed parameters show the module’s firmware
version, etc. Monitor parameters display output current and system voltage. Use variable parameters to configure
the controller, such as maximum output current, operating mode, etc. Some parameters combine variable and
monitor in one line. Use it to set a variable according to the current monitor value.
Press the unlock button to enter the edit mode. An asterisk (*) will appear at the beginning of the second line. Use
the up and down buttons to change the value. For parameters containing both variable and monitor, the monitor
data is in square brackets.
Press the lock button to save the parameters and end edit mode.

When the lock button is pressed, the changes take effect immediately. Change values only when the machine is
NOT running.
“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”.

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 will
display the MVP settings from the data file.

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.
For RP2, the output current is initially set to the Minimum.
•The output current increases from Minimum to Maximum within the Ramp Up time
when switching ON “ENABLE” switch.
•The output current decreases from Maximum to Minimum within the Ramp Down
time when switching OFF “ENABLE” switch.
MIN OUTPUT Sets the minimum output current (milliamps, amps for -12A,-25A). The value in the
brackets is the present output current.
MAX OUTPUT Sets the maximum output current (milliamps, amps for -12A,-25A). The value in the
brackets is the present output current.
DITHER FREQ. Options: 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, (Select OFF for
1000Hz). Set the PWM or dither frequency according to the valve specifications. This
parameter is variable.
OUTPUT CURRENT Displays the present output current. This parameter is a monitor type.
SUPPLY VOLTAGE Displays the module’s power supply voltage. It is helpful for troubleshooting. This
parameter is a monitor type.
FAULT STATUS The STATUS LED will flash red 2 times for Coil Open and 3 times for Coil Short.
