    1 GENERAL

    1.1 Description for Control BoardP/N VC002475 for ModulatingApplications

    The Control Board connects to the Motor Board with a 10position plug-in connector and 3 mounting screws thatare captured in the board. The Control Board allows theactuator to modulate (change position) in response to achange in an analog control signal.The input control signalis 0-135 . The control board also features analog positionfeedback, signal fail options, speed control, lockedrotor/stall protection, simple push button set-up, and autocalibration.

    1.2 Operating Modes

    The Control Board has five operating modes. Run, Manual,Set Span, Set Zero and CAL (calibrate). A rotary ModeSelector Dial on the Control Board allows the user tochange the operating mode. To change mode, turn therotary selector knob with fingers or a small screwdriver.Five LED indicators around the knob correspond to one ofthe five modes.When the Control Board mode dial is set toany mode, the corresponding LED turns on, indicating themode is selected.

    Run mode is the basic operating mode. The actuatorwill respond to a command control signal which issupplied to terminal A and terminal B on the ControlBoard.

    Manual mode permits the user to override the controlsignal and drive the actuator by using the [CW] and[CCW] push buttons. In Manual mode the actuator willnot travel beyond the saved settings for the Zero andSpan stop positions.

    Set Span mode permits the user to precisely correlatethe end of span travel stop with a correspondingcontrol signal value. Typically, the Span position is thefully counter-clockwise position and maximum controlsignal value, but Span may be set at any position orsignal value.

    Set Zero mode permits the user to precisely correlatethe opposite end of travel stop position with a corre-sponding control signal value. The Zero position istypically the fully clockwise position and minimumcontrol signal value,but Zero may be set at any positionor signal value.

    Cal mode allows the user to automatically calibratethe position tracking potentiometer without the useof an ohmmeter or other electronic instruments.

    1.2.1 Features, Settings and Controls

    The control board is designed to be easy to use and hardto break. Set Up is push button simple and takes oneminute! See (Figure 1) for callouts. Enter is located directly below the mode selector and

    permits the user to activate modes and confirm settingsby pressing the [ENTER] button.

  • Control Signal The board accepts a 0-135 inputcontrol signal. Make sure the Signal Select switch iscorrectly positioned for the input control signal.

    Feedback Signal Selection The board provides afeedback signal indicating actuator output position.This signal can be either current or voltage. Make surethe Signal Select switch is correctly positioned for thedesired feedback signal. If the feedback signal is notused, the switch may be left in either position.

    Control Fail Position In the event that the controlsignal to the actuator is lost and power is still applied,the the actuator will drive to the ZERO position. Theactuator will maintain the Zero position until the 0-135 control signal returns to terminal A and termi-nal B.

    Manual Supervisory Control Selecting Manual(Man)Mode will override the connected control signaland allow driving the actuator to any positionbetween Zero and Span, using the CW and CCW pushbuttons. There is no need to disconnect or handle livewires.

    Deadband Deadband is the window of control signalchange which the actuator will ignore. The sensitivityof the actuator to respond to changes in the controlsignal is adjustable. Minimum deadband allows theactuator to respond to small control signal changes.Maximum deadband allows the actuator to ignoresmall control signal changes (such as noise on thecontrol signal). Deadband adjustment from Minimumto Maximum varies the dead band from small (1%) tolarge (3%) of input signal.The deadband should be setto the maximum amount which the process will allow.

    Speed Control The Control Board will slow the actu-ator by pulsing the motor if the Speed Control featureis utilized. The speed of the actuator can be regulatedfrom 1:1 (normal) to 20:1 (1/20th of the normal cycletime) by adjusting the Speed Control dial on theControl Board.

    Locked Rotor Protection Locked rotor protectionprevents the overheating of the motor and possiblepremature failure. The Control Board provides lockedrotor protection and Stall LED Alarm in the event of astall condition such as a jammed valve or damper.Should the actuator stall before reaching the positioncommanded by the control signal, the actuator willremove power to the motor within 2-5 seconds. TheStall LED on the Control Board will continue to flashuntil a reverse control signal clears the stall condition.

    1.3 Control Board Wiring

    To operate the actuator with the Control Board installed, theuser must supply power to terminal 1 and terminal 2, only!Power to terminal 3 and terminal 4 can cause damage tothe Motor Board. See (Figure 2) for Diagram.

    Power wiring to the Motor Board should be properlygrounded in accordance with local electrical code.

    Control signal wiring to the Control Board terminalsshould be properly shielded. To further prevent controlsignal noise, control signal wiring should be separatedfrom the power wiring and should enter the actuatorthrough a conduit opening separate from the entry usedfor the power wiring.

    Terminal 5, counter-clockwise, and terminal 6, clockwise,position indication does not apply to actuators with theControl Board option. If status feedback is required withthe Control Board option, install optional limit switches oruse the standard readback feature provided with theControl Board. See (Section 2) for additional switches.

    1.4 Operation for Modulating Applications(Motor Board and Control BoardInstalled) (90 Rotation)*

    When Control Board is installed, power to terminal 3 or toterminal 4 will damage electronic circuit boards. Powerterminals 1 and 2; Use [CW] Clockwise and [CCW]Counter-Clockwise buttons to drive actuator.
