Startup
Start the power supply either in local mode or in remote mode by setting the power
ON remote (PON REM) switch which is located on the unit’s rear panel. See
Table 2.9 for the switch settings.
Table 2.9 Remote/Local Start-up Settings.
With the rear panel PON REM switch set to 0, the power supply will start up in
remote mode. The green REM LED on the front panel will turn on, signaling that
the power supply is under the control of the digital interface card. The output of the
power supply is active on startup. To promote load safety, power ON defaults are
zero for the output voltage and current limit, and 110% of maximum output voltage
for the OVP trip point. See Table 2.10. Refer to Section 3 for more information
about the interface commands listed in the table.
If the rear panel PON REM switch is set to 1, the power supply will power up in
local mode. Power supply control is at the front panel. During an operating session,
you can toggle between local mode and remote mode by sending commands as
described in Table 2.10.
