  • Page 105: Appendix F. Valve Expansion Board Option

    APPENDIX F VALVE EXPANSION BOARD OPTION Description The Valve Expansion Board gives the Control the ability to drive up to eight additional valves. Each set of connections provides 115 VAC (standard) or 24 VAC (optional) power to the valve solenoid connected across those connections.

  • Page 107: Appendix G. Voltage Monitor Board Option

    APPENDIX G VOLTAGE MONITOR BOARD OPTION Description The Voltage Board gives the Control the ability to compare weld voltage against pre- programmed high and low limits. This board allows you to monitor either peak or average (RMS) voltage. You can also select when the voltage is monitored, either during both weld periods (excluding up/downslope) or during the last cycle only.

  • Page 109: Appendix H. Force Control Option

    APPENDIX H FORCE CONTROL OPTION Description The Force Control (Force Output) Option can control up to 8 electronic pressure regulators. Output Force is programmed in lbs using front panel controls. Once the Operator programs the Output Force, the Control converts this to the correct voltage to be sent to the electronic pressure regulator in order to get the desired force.

  • Page 111 APPENDIX H: FORCE CONTROL OPTION Maintenance/Replacement Disconnect the serial cable connector (26-pin ribbon cable) connected to J10 on the Force Board. Disconnect the force input cables from J1 and the force output cables from J2 and J3 on the Force Output Board as required. Slide the card out of the card cage.
  • Page 113 APPENDIX I PRESSURE MONITORING OPTION Description The Pressure Control Option (Force Input) uses differential pressure sensors on up to eight channels. You may use this feature in a Force- Firing function (welds only when correct pressure is reached), or as a pressure monitor to see if air pressure reached (or exceeded) the desired range.
  • Page 114 APPENDIX I: PRESSURE CONTROL OPTION Channel Number Setup Each Pressure Board is manually assigned to a specific channel at the factory using the dipswitch on each board. If you are replacing a Pressure Board(s), you will have to set each one to a different channel.
  • Page 115 APPENDIX I: PRESSURE CONTROL OPTION Place a force gauge between the electrodes. If the force output option is installed, press the button on the WELD ON Control Panel to close the electrodes. NOTE: In FORCE CALIBRATION mode, the Control will not send weld current to the electrodes.
  • Page 116 APPENDIX I: PRESSURE CONTROL OPTION Maintenance/Replacement Label the air hoses from the Pressure Board(s) you want to remove. Note the location on the board and label them appropriately. Hoses cannot be switched! Remove the hoses. Unplug the Pressure Board(s) from the Force Board. If you are using multiple Pressure Boards, disconnect them in order to remove/replace/install specific boards.
  • Page 117 Appendix J Communications Option Section I. Description An optional circuit card gives the Control the ability to communicate with a host computer or with automation control systems. The communications option uses either RS-232 to connect one control to one host or RS-485 multi- drop architecture to connect up to 30 controls to one host on a single channel.
  • Page 118 APPENDIX J: COMMUNICATION OPTION RS-485 / RS-232 Operation The STA Communications Option card can be used for RS-232 or RS-485 protocol. The wiring of the external 9-pin connector is determined by the internal serial connector supplied at time of purchase. The connectors shown on the right are from the cables that go between the external 9- pin connector on the Control and the Communications Board.
  • Page 119 APPENDIX J: COMMUNICATION OPTION A good guideline is that on a line free of electrical noise, the number calculated above must remain less that 70% of the theoretical maximum capacity (26,880 bytes per second). Electrical noise on the communications lines will further reduce this capacity. Shielded cables are recommended. Several commands require the Control to be in HOST mode for the Control to accept them.
