9. Remote Analog Control (Option)
Analog control and monitoring requires an optional analog control card. If the unit was shipped
with the analog control option card from the factory it should be properly configured to use the
option card, see
6.3.8.Hardware Options Configuration
for details on configuring an option card.
Analog control is used when the power supply is put into remote control mode (RMT lamp is on)
and the source of the current and/or voltage settings is set to option card control (as opposed to
being set to host control). See
6.3.3.Remote Control Configuration
for details on selecting the
option card for remote control.
See
5.6.Analog Card Connections (Optional 138-0471-XX Card)
for proper for analog control
connections.
NOTE:
The host can dynamically switch between analog control and host control if desired. See
B.1.12.

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.
9.1. Remote Analog Read Back
The current and voltage readings from the LT SERIES DC rectifier can be monitored using the
analog outputs on the analog control card. The option card analog outputs will always reflect the
current and voltage readings. The analog outputs are proportional to the readings as shown in the
following tables.
