100 M447352-01 REV-A
10 REM
The source is presently controlled by the remote digital interface. If the
RS-232C, USB, or LAN interface is used, the REM state can be enabled
by the external controller using the SCPI command, SYST:REM. If the
optional IEEE-488 (GPIB) interface is used, this indicator will be lit
whenever the REM line (REM ENABLE) line is asserted by the IEEE-488
controller.
Any time the REM LED is lit, the front panel control of the unit is disabled.
To regain control through the front panel, the external controller must
send the SCPI command, SYST:LOC.
11 FAULT
A fault condition has occurred; the output is shut down, the isolation relay
is open, and the output voltage is programmed to zero.
12 LXI LXI status annunciation.

5.2 Front Panel Display Navigation
The selection of the output characteristics and adjusting the output parameters through the front panel
display could be accomplished using the DASHBOARD screen (refer to Figure 5-20) or the OUTPUT
PROGRAM screen (refer to Figure 5-8). The selection and adjustment of items could be done using either
the touch-screen or rotary encoder:
1. Using the touch-screen or rotary encoder, navigate (refer to Section 5.4.1 and Section 5.4.2) to
the HOME Screen, and select the OUTPUT PROGRAM screen (refer to Figure 5-8). Within the
OUTPUT PROGAM screen, select the parameter, and adjust its value.
2. The DASHBOARD screen provides an alternate means of adjusting the primary parameters,
voltage, current, and frequency, in the same menu. It is also located on HOME Screen. It has the
additional functionality of real-time adjustment of the parameters as the encoder is rotated (refer
to Section 5.4.2).
5.3 Selecting Output Characteristics and Adjusting Parameters
To set up the power source for basic operation with either a sine wave or DC output, perform the following
sequence:
Source Mode: (Applicable for Sequoia series and Tahoe series)
1. Navigate to the PHASE NUMBER menu in the CONFIGURATION screen and select the output
phase number: either One-Phase or Three-Phase.
2. Navigate to the PHASE menu in the OUTPUT PROGRAM screen, and select the output phase
angle: Phase-B and Phase-C relative to Phase-A.
3. Navigate to the MODE menu in the CONFIGURATION screen, and select the output voltage
mode: either AC, DC, or AC+DC.
4. Navigate to the RANGE menu in the CONFIGURATION screen and select the output range: either
Low-Range or High-Range.
5. Navigate to the REGULATION menu in the CONFIGURATION screen and select the output
voltage/Current Regulation: either Constant Voltage/Constant Current or Constant
Voltage/Current Limit.
6. Navigate to the VOLTAGE menu in the OUTPUT PROGRAM screen and adjust the output voltage
value.
7. If the AC+DC voltage mode had been selected, navigate to the DC OFFSET menu in the
CONFIGURATION screen, and adjust the DC component of the output voltage.
