Install the controller in the rack mount cabinet prior to making any electrical connections. 2.4.2 Cooling This controller is forced air cooled with the airflow entering through a vent in the back panel of the chassis.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION 3 OPERATION The AC Discharge Controller can be operated in Local and Remote modes. Mode selection between Local and Remote modes is controlled using a switch located on the front panel of the controller. A lighted indicator is located above and below this switch to indicate local or remote mode.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION Remote Shutdown indicator – Indicates that remote shutdown has been com- manded through the analog or RS-232 remote interface. Enable/Standby switch – Enables or disables the output. When Standby is selected, the Discharge Amps Setpoint is displayed. When Enabled is selected, the controller regulates the Cathode Amps/Volts to main- tain the Discharge Amps Setpoint.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION labeled, “RS-232”, “AC Discharge”. This approach uses an RS-232 straight through cable that connects to a DB-9 male connector. 3.2.1 Direct RS-232 connection from computer to AC discharge controller The AC Discharge Controller can be operated from a host computer using an RS-232 port on the computer.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION value from 0-4095. VA0 is the minimum or zero output, it also puts the unit in standby mode, while VA4095 is maximum output. • *IDN? Returns the 4 digit product identifier code. • RD0 Returns a decimal number for conversion to the corresponding cath- ode voltage.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION • Powering down the AC Discharge Controller should be done by resetting the output current to zero, this is done by inputting the following command into the terminal program: Input “VA0” then press the enter key. The dis- charge will drop to zero and the Standby LED will be illuminated.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION The AC Discharge Controller can be operated using analog. 3.2.5.1 ANALOG Input/Output The AC Discharge Controller can be remotely controlled using a 0-5 volt DC analog interface. The analog remote uses 0-5 volt signals for controlling and monitoring the controller.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 OPERATION Number Description Common Common. Auxiliary +5 volts DC, 200 mA max. Also available at pin 15 and 25. Remote Shutdown, Active Low – Output is disabled when connected to common. The shutdown is deactivated when 5 volts is applied or no contact is made.
AC DISCHARGE CONTROLLER MANUAL MODEL AC1006 DIAGNOSTICS 4 DIAGNOSTICS 4.1 General The AC Discharge Controller has been designed for operating a filament cath- ode in a vacuum environment for use in a electron source. The filament cathode provides electrons for starting the ion source in addition to neutralizing the ion beam.
