Front Panel Operation

3.10 Tour of the Front Panel

Before operating the AC source using the front panel, it helps to understand the operation of the
front panel controls. Specifically, the operation of the knob, keyboard and the menu layout are
covered in the next few paragraphs.

3.10.1 Front Panel Controls and Indicators

The front panel can be divided in a small number of functional areas:

Mains circuit breaker

Status Indicator lights

Shuttle knob

LCD display

FUNCTION keypad

DATA ENTRY keypad

3.10.2 Mains Circuit Breaker

The circuit breaker located on the bottom left side of the front panel disconnects the AC source
from the three phase Line input. It will automatically trip when the input current rating of the unit
is exceeded due to some component failure. The contrasting black color and large size throw
bar make it easy to locate in case of an emergency.

3.10.3 Status Indicator Lights

Four LED status indicators are located directly above the mains circuit breaker. These LED’s
correspond to the following conditions:

REMOTE

The REMOTE LED indicates that the unit is in remote control
mode. If the IEEE-488 interface is used, this indicator will be lit
whenever the REM line (REMOTE ENABLE) line is asserted by
the IEEE controller. If the RS232C, USB or LAN interface is
used, the REMOTE state can be enabled by the controller
using the SYST:REM command. Any time the REMOTE LED is
lit, the front panel of the i Series unit is disabled. There is no
LOCAL button that allows the user to regain control of the front
panel. This prevents accidental change of settings in ATE
applications.

OVERLOAD

The OVERLOAD LED indicates an output overload condition.
This condition can be controlled by setting the current limit
value in the PROGRAM menu. Removing the load using the
OUTPUT ON/OFF button will recover from an overload
condition.

OVERTEMP

The OVERTEMP LED indicates an overheating problem inside
the unit. This is an abnormal condition, which will cause the unit
to shut off. Check the air openings to make sure they are not
blocked.

HI RANGE

The HI RANGE LED is on when the high voltage output range
has been selected.
