3 DRC PHYSICAL DESCRIPTION The DRC is shown at the right. There are five indicator lamps labeled PR and OUT through OUT4 (for the four channel controller). The PR lamp will light green whenever power is applied to the unit and is within the specified voltage range. Under normal operation the OUTx lights will provide an indication of the current being supplied to the solenoid output for a given channel. The lights will be yellow and the brightness will vary with the output current. In the case of a fault the light will flash red with a flash code corresponding to the type of fault for that channel. Communication with the DRC takes place through the USB port. The port allows for configuration and monitoring of the operating parameters. Note: hen connected to a PC, the DR controller will be recognized as a USB device with or without power applied to the controller. However, to configure the controller it must be powered. APPLICATIONS DRC- V-* (Single Solenoid Joystick Control) The DRC can be controlled with a joystick or potentiometer as shown. The recommended potentiometer value is 0k Ω. Mode may be used rather than Mode if the enable is not used. Dither and Output settings will vary depending on the valve and application. NEG POS J 9 to VDC 4 AMP VALVE EMERGENCY STOP ENABLE C JOYSTICK J DRC- V-* (Double Solenoid Joystick) The DRC can be setup to drive a double solenoid valve using one command as shown in the following diagram. If enable is not used, C Mode shoul be set to and C Mode to. The minimum and maximum input parameters for the two channels must be set such that both outputs will not be active with the same input signal. The settings do not have to be the same or mirrored between the two channels as shown in the example though in many cases they will be. Dither and Output settings will vary depending on the valve and application. NEG POS 9 to VDC J 4 AMP 4 EMERGENCY STOP VALVE ENABLE C JOYSTICK J 4 Friendship Drive, Magnolia, TX 7755 Tel.: Fax:

6 PHYSICAL DESCRIPTION The is shown at the right. There are two indicator lamps labeled STATUS and OUTPUT. The STATUS lamp will light green whenever power is applied to the unit and is within the specified voltage range. The STATUS light will flash red when a fault has occurred. The type of fault is indicated by the number of successive flashes. It will continue to flash until the command signal has been removed to clear the fault. The yellow lamp labeled OUTPUT provides an indication of the current being supplied to the solenoid outputs. Communication with the takes place through an infrared interface port. The port allows for configuration and monitoring of the operating parameters. The infrared adapter clips onto the aligning with the notches in the sides. IRING ire functions are listed in the table below. Folowing the table are wiring examples for various modes of operation. 9-8 VDC Terminal BRON E BLACK TE GRN/YEL Command Function V Supply Supply Command Input Input 5V Reference* Connector Ground Single Solenoid Joystick Control The can be controlled with a joystick or potentiometer as shown. This configuration uses Mode with the signal or Mode with no line. Single Solenoid -Speed Control The can be configured for -speed mode as shown. In this arrangement the signal allows minimum output and the Command signal allows maximum output. This configuration corresponds to Mode 5. Single Solenoid -Speed Control The can be configured for -speed mode as shown. In this arrangement the signal allows maximum output and the Command signal limits output to the minimum setting. This configuration corresponds to Mode VDC Slow Down *NOTE: If the 5V Reference is not used it must be isolated to prevent shorting to other wires. Failure to do so can result in damage to the controller. 4 Friendship Drive, Magnolia, TX 7755 Tel.: Fax:

7 IRING continued Single Solenoid PLC Control The can be controlled with PLC as shown. This configuration uses Mode with the signal or Mode with no line. 9-8 VDC Command Double Solenoid Two s can be driven by one signal for double solenoid operation as shown in the following diagram. One should be set to Mode or while the other is set Mode or 4. The minimum input parameters for the two should be set such that both units will not be active with the same input signal. *NOTE: Loss of Command signal in his configuration will result in maximum output to one solenoid. Care must be taken to avoid injury or damage in the event of a signal failure! Two s can be driven by one signal for double solenoid operation as shown in the following diagram. This configuration uses a selector switch to determine which solenoid is activate and a single potentiometer to determine output level. This configuration corresponds to Mode or Mode. 9-8 VDC Fast ORDERING INFORMATION ORDERING EXAMPLE - CV - A - 0F Series =.A output 5 =.5A output CV = 0 to 0V input 0F = 0 ft. cord 5F = 5 ft. cord 4 Friendship Drive, Magnolia, TX 7755 Tel.: Fax:
