4.1.3 Status Indicator Lights
Five LED status indicators are located to the left of the LCD display. These LED's correspond to
the following conditions:
REMOTE
OVERLOAD
OVER TEMPERATURE
HI RANGE
OUTPUT
MX15 Series
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 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 MX Series unit is disabled. The BACK key
doubles as a LOCAL button that allows the user to regain
control of the front panel.
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.
The OVER TEMPERATURE 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.
The HI RANGE LED is on when the high voltage output range
has been selected.
The OUTPUT LED is on when the output relay is closed.
