DRC Valve 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.
DRC Valve 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.C.
DRC Valve Controller DRC Controllers The DRC controller drives proportional solenoid valves. The output current is proportional to the command input. Once configured, the settings are permanently stored in the controller memory.
DRC Valve Controller Physical Description There are PWR LED and OUTx LEDs. For DRC-4, there are 5 LEDs. The PWR LED is green when the applied voltage is within the operating range. OUTx LEDs indicate current output for a given channel. The LEDs are yellow and the brightness will vary with the output current. In the case of a fault the LEDs will flash red with a flash code. It will continue to flash until clearing faults by moving the command signal out of active range or cycling the power.
DRC Valve 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.
DRC Valve 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-DRC Rev A DRC User Manual Copyright © High Country Tek, Inc.
DRC Valve 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 will display the DRC settings from the data file. 021-DRC Rev A DRC User Manual Copyright © High Country Tek, Inc.
DRC Valve Controller Parameter List The following table outlines the DRC parameters as well as the limits and units of measure for each parameter. Parameter Limits Units DRCx-xxx Version # C1 Mode See Mode Description Mode # C1 Min input -10 to +10.0 V 4 to 20.0 mA -10 to +10.0 V 4 to 20.0 mA 0 to 600 1 mA C1 Max output 0 to 600 1 mA C1 Ramp up 0.0 to 120.0 Seconds C1 Ramp down 0.0 to 120.0 Seconds 30 to 1000 Hz.
DRC Valve Controller DRCx-xxx - The title parameter is fixed. It displays the model number and the firmware version. Cx MODE - Three modes of operation. Mode Enable 1 IN1 NO ENBL 2 IN1 USE ENBL 3 IN1 FOLLOWER Channels and description 1, 2, 3, 4, use its own input. x 1, 2, 3, 4, use its own input. 2 (use input from C1), 4 (use input from C3) E.g., to drive two-coil directional proportional valve(s), set C1 & C3 to mode 1 or mode 2, Set C2 & C4 to mode 3. Do not overlap the input ranges.
DRC Valve Controller Dual-coil valve control: Positive input drives channels 1 and 3, negative input drives channels 2 and 4. Channel 2 uses the input from channel 1. Channel 4 uses the input from channel 3. Ignore the input readings from channels 2 & 4. 10.1V input drives channel 1 output to the max current setting of 0.5A. 5.8V input drives the channel 1 coil to 0.29A. 0.3V input is in the dead-band, the channel 3 and 4 output current is 0A.
DRC Valve Controller Dual-coil valve control: Positive input drives channels 1 and 3, negative input drives channels 2 and 4. Channel 2 uses the input from channel 1. Channel 4 uses the input from channel 3. Ignore the input readings from channel 3 & 4. -0.3V input is in the deadband, channel 1 and 2 output current is 0A. -7.3V input drives channel 2 output to 0.37A. -9.5V input drives channel 4 output to 0.49A. -6.5V input drives channel 4 output to 0.33A.

DRC Valve Controller Example Settings Application Examples Open Loop Single Solenoid Control (DRC1-Vxx) The DRC can drive a single solenoid with a joystick or potentiometer of 10kΩ. Mode 1 is used when the enable switch is not used. Mode 2 is used when the enable switch is used. The command input can be inverted. Set the dither and output settings according to the valve specifications. Schematic Parameter C1 Mode Value 2 IN1 USE ENBL C1 Min input 0.2 V C1 Max input 10.
DRC Valve Controller Open Loop Double Solenoid Control (DRC2-Vxx) Example Settings The DRC can drive a double solenoid valve with a joystick or potentiometer of 10kΩ. Parameter Value C1 Mode If enable switch is not used, set channel 1 to be Mode 1, channel 2 to be Mode 3. If enable switch is used, set channel 1 to be Mode 2, channel 2 to be Mode 3. The minimum and maximum input parameters for the two channels should not be overlap.
