9.2. Remote Analog Setting Control
The LT SERIES DC rectifier’s voltage and current settings can be controlled through the analog
option card when the power supply is in remote mode (indicated by the RMT lamp being on) and
the source of the current and/or voltage settings is set to option card control (see
6.3.3.Remote
Control Configuration
). The RMT/LCL switch is used to change to the remote mode. When the
power supply is in remote mode the voltage and current settings cannot be adjusted from the front
panel. The unit output levels are proportional to the analog input levels as shown in the following
tables.
NOTE:
The local/remote mode will be retained through a power cycle. See
6.3.4.Power On
Configuration
for information on how to retain the operate/standby mode through a power cycle.
