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.
Programmable parameters include: Maximum current, current ramp time, ramp current,
beeper control, and communication settings (mode, speed).
For uses requiring PID control loop capability, a remote control unit (such as the STC-2000)
can be connected to the RS-3000.

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. This allows remote control of the RS-3000 by a PC.
There is a 6 pin modular connector (RJ-11) at the front of the unit for a hand controller.
The standard hand controller cord length is 6 feet when the coiled cord is fully extended.
Front Panel Interface
There are 6 front panel keys that are used to program the unit, change modes, and
start/stop the unit.
There are two 3 character displays.
The larger display is located near the top of the front panel.
The smaller display is located near the center of the front panel.
The larger display can show: mode (such as O.F.F. or Err), ramp current, and current.
If problems occur, an Error message is indicated by the letters Err appearing in the
larger display.
In program mode (current or new values can be seen or set): max current, ramp
current, beeper [on/off], speed, and address.
The smaller display can show: minutes and kilowatts
If problems occur, an error message is shown on the smaller display.
Examples are: Opn (for open boat) or Hot (for power supply over temperature
condition).
In program mode (existing or new values can be seen or set): ramp minutes,
[beeper] on/off, etc.
There are 9 LED illuminated indicators. Some indicators show the mode status: PRGM
(for program mode), RMT (for remote mode), and MAN (for manual mode). Other
indicators are associated with and show the value type of the data shown on the displays.
For example, with the first press of the program key (PRGM) the large display shows a
value, and the CUR and MAX LED indicators are illuminated. This indicates that the value
shown on the large display is the maximum current. With the second press of the program

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. This
indicates that the value shown on the large display is the ramp current. In these cases, the
INC and DEC keys are used to set the values as needed. The program (PRGM) key
sequences through the programmable elements with each subsequent press until all
elements have been shown. In the programming mode, the program mode LED is
illuminated and flashing. When the program mode LED turns off the last of the
programmable elements is no longer shown and displays revert to the mode context from
which the program mode was launched.

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. The Kilowatts value is the power being expended at the
supply output. The time value is the elapsed time from the press of the start key. The
Kilowatts and time values are differentiated by the illumination of either the Kw or MIN
LEDs. Pressing the stop key ends the manual mode which is confirmed by the display of
the text O.F.F. in the large display. The pendant stop key is equivalent to the front panel
stop key. Pressing the stop key places the RS-3000 into a quiescent state where the power
output ON/OFF signal to the T3000 is set to OFF (see section 10.1, pin 13) and the RS3000 analog output to control the T3000 power output is set to zero (see section 10.1, pin
7).
3.3 Ramp mode
Whether the RS-3000 is in manual mode or ramp mode is determined by the value of ramp
minutes. If ramp minutes is at a non-zero value, that is, any value but 0.0, then ramp mode
will be entered when the start key is pressed. This is confirmed by the fact that the MIN
value is counting down and that the MAN LED is not illuminated. Ramp mode does not
have a specific LED indicator.
In the ramp mode, the AMPS value shown in the large display changes based on the
programmed values of ramp current and ramp minutes. The AMPS value displayed is the
basis for what is requested from the power supply. Meanwhile, the small display alternately
shows Kilowatts and minutes. The Kilowatts value is the power being expended at the
supply output. The time value is the remaining time until ramping terminates at the desired
current. The Kilowatts and time values are differentiated by the illumination of either the Kw
or MIN LEDs. Pressing the stop key ends the ramp mode which is confirmed by the display
of the text O.F.F. in the large display. If the stop key is not pressed, the MINutes value will
count down to zero (while the power ramps up to the programmed value) and then the unit
will automatically go into the manual mode after zero minutes remaining has been
achieved. When in the manual mode the MINutes time will advance indefinitely at the last
power level set during the ramp mode.
Pressing the stop key during the RAMP mode or in the subsequent Manual mode, places
the RS-3000 into a quiescent state where the power output ON/OFF signal to the T3000 is
set to OFF (see section 10.1, pin 13) and the RS-3000 analog output to control the T3000
power output is set to zero (see section 10.1, pin 7).
3.4 Remote mode
This mode uses a remote controller (such as the STC-2000) to control the power supply
output.
Pressing the RMT key puts the unit into the remote mode. This is confirmed by the
illumination of the RMT LED. Pressing the RMT key again takes the unit out of the remote

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. The T3000 power
supply will not be controlled until this condition has been satisfied with a digital low
or ground (see section 3.6.10.2, pin# 3).
3.5.2 Open boat: indicated on the large and small displays in terse text as Err Opn (error
open). Indicates an open boat. This condition must be sensed after power is
applied and therefore a reset on the power supply can take a while to re-sense the
open boat condition. The T3000 power supply will not be controlled until this
condition has been satisfied with a digital low or ground (see section 3.6.10.1, pin#
1).
3.5.3 Over temperature: indicated on large and small displays in terse text as Err Hot
(error hot). Indicates an over temperature condition within the power supply. This
condition is sensed immediately and will not allow a reset on the power supply to
properly reset until the temperature has returned to a normal temperature range.
The T3000 power supply will not be controlled until this condition has been satisfied
with a digital low or ground (see section 3.6.10.1, pin# 9).
3.5.4 OOP: when indicated on both the large and small displays, this means that the
system has encountered a microcontroller induced reset from which it has
recovered. Condition indicates possible memory or microcontroller failures.
3.5.5 Err/PrG: indication for NV mem default due to error. This error condition can be
cleared by pressing the PRGM key.
3.5.5 Current maximum: when the requested current reaches the maximum value, the
MAX LED indicator blinks.

sequence, terminates the PRGM mode and the
PRGM indicator ceases to blink. Parameters are
saved immediately as they are entered (there is
no quit without saving). If there is a lack of activity
for 30 seconds during the programming sequence,
the programming mode will auto-terminate.

Service
The unit is best opened by removing the 4 back panel screws then the four connector
securing hardware (capturing) standoffs. Remove back panel. Remove top by sliding it
rearward. Slide main board rearward to remove (note connection to front panel board) or
service the fuses or jumpers without removing main board. Take care not to touch
electronic devices or circuitry such that a high voltage discharge path from your finger may
develop and destroy components.
There are 2 socketed internal fuses. One for VCC (labeled F1) and the other for +12 volts
(labeled F2).
The RS-3000 power-on event sequence is as follows. The green power LED is illuminated.
Next, the unit momentarily illuminates all LEDs and display segments. Then it momentarily
displays its software version number (large display) and 300 (T3000 wired in series) or 600
(T3000 wired in parallel) in the small display. If the number displayed does not match the
actual configuration, check the wiring select switch on the T3000. If there are no error
conditions, the RS-3000 will display 0.F.F. in the large display.
