Use of the T3000 with the RS-3000
4.1 Introduction
This chapter contains information on operating the T3000 power supply using an RS-3000
controller. The RS-3000 functions as a user interface for the T3000, and supplies the
control voltages needed to operate the T3000. The RS-3000 also displays system faults
with a combination of text messages on the displays, and/or 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.
Programmable parameters include: Maximum current, current ramp time, ramp current, and
beeper control.
For uses requiring PID control loop capability, a remote control unit (such as the STC-2000)
can be connected to the RS-3000.
For operation of the T3000 and RS-3000 using a PC connected to the RS-232 port, see the
RS-3000 manual.
4.2 Description
Dimensions: The RS-3000 is 3
7/8
inches wide by 3
3/4
inches high by 5
5/8
inches deep.
The unit is rack mountable next to the T3000 power supply.
Keys: There are six front panel keys used to program, change modes, and start or stop the
unit.
STOP: Used to abort the current operation (switch the T3000 power output to zero)
from Ramp, Manual or Remote mode.
START: Used to start Ramp mode or to switch from Ramp mode to Manual mode.
PRGM: Used to enter Program mode, step through the programmable parameters,
and exit Program mode.
RMT: Used to toggle between Remote and Manual modes.
INC: Used to increase the value of the maximum current, ramp time (minutes) or
ramp current, toggle the beeper on or off, and select baud rate.
DEC: Used to decrease the value of the maximum current, ramp time (minutes) or
ramp current, toggle the beeper on or off, and select baud rate.
Displays: There are two 3-character displays. The larger display can show mode (such as
“Off” or “Err”), ramp current, and current. The smaller display can show minutes and
kilowatts. Error messages are shown on the smaller display.
