instruments Power Supply Controller RS-3000 Section 1 Description of Equipment The RS-3000 functions as a user interface for the T3000 resistive power supply, and supplies the control voltages needed to operate the T3000. The RS-3000 also displays system faults in text message form or by indicator LEDs. The RS-3000 can be controlled from the front panel, with a hand controller (or pendant), or via the back-panel RS-232 connection.

instruments Power Supply Controller RS-3000 Section 2 Connections There is a 15 pin d-sub male connector at the back of the unit that is used to connect to the T3000 power supply. The RS-3000 is powered by the T3000 power supply. There is a 15 pin d-sub female connector at the back of the unit that is used to connect the RS-3000 unit to a more sophisticated control unit (such as the STC-2000). There is a 6 pin modular connector (RJ-11) at the back of the unit for RS232/485 communication.
RS-3000 Power Supply Controller instruments key (PRGM) the large display is blanked while the small display shows a value. The LED indicators that are illuminated now include the RAMP and MIN LEDs. This indicates that the value shown on the small display is the ramp minutes. With the third press of the program key (PRGM) the small display is blanked while the large display shows a value. The LED indicators that are illuminated now include the RAMP and CUR LEDs.

RS-3000 Power Supply Controller instruments mode will be entered when the start key is pressed. This is confirmed by the illumination of the MAN LED indicator. In the manual mode, the AMPS value shown in the large display can be varied using the INC and DEC keys on the front panel or pendant. The AMPS value displayed is the basis for what is requested from the power supply. Meanwhile, the small display alternately shows Kilowatts and minutes.
instruments Power Supply Controller RS-3000 mode. During the remote mode, only Kilowatts and AMPS are shown. The stop key on the front panel or pendant can also be used to cancel the remote mode. The connection to the RS-3000 from the remote controller is through a 15 pin female DSUB connector on the back panel. 3.5 Error/problem Conditions 3.5.1 Interlock: is indicated by the illumination of the INTERLOCK LED on the front panel. This indicates that continuity of the interlock system is open.

instruments Power Supply Controller RS-3000 Section 4 Specifics 4.1 Events and modes Various events cause mode changes. Events can include: elapsed time decremented to zero, amperage reaching a programmed value, an over-temperature condition, an open boat condition, loss of interlock continuity, or user interaction with front panel or pendant keys. Following are specific events and their effects on the various modes. Table 4-1 Manual Mode Event START key From O.F.F.
