4.1.3 Status Indicator Lights
Five yellow LED status indicators are located on the left hand side of the keyboard/display panel.
These LED’s correspond to the following conditions:
Hi Range The Hi Range LED is on when the high voltage output range has
been selected.
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.
Overcurrent The Overcurrent LED indicates an output current that exceeds the
programmed setting. 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
when in CV mode.
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
ATN line (Attention) line for the GPIB address set is asserted by the
IEEE controller. If the RS232, 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 power source is disabled. Note: The BACK button
doubles as a GOTO LOCAL button (LOCAL) while the unit is in
remote state. This allows the user to regain control of the front panel.
The LOCAL button can be disabled by sending a Local Lockout bus
command
1 . This prevents unauthorized changes of settings in ATE
applications.
Output The Output LED indicates the output relay status. If the LED is off,
the output relay is open. If the LED is on, the output relay is closed.
øA, øB, øC The Phase LEDs indicate the phase selection in effect. For setup
screens, phase selection is either one individual phase or all phases
(coupled). For the measurements screen, selection of all phases will
default to displaying measurement data for phase A only. If the
2253i/iX has the –MODE option and is in single-phase mode, the
phase A LED is always lit and the PHASE button has no effect.
1 Note: When using the iXCGui Windows program with USB, RS232 or LAN interface, the local function is disabled. See
programming manual for user application programming.
