Remote/Local Function
Introduction The remote/local function is controlled by the
system controller and with the FAST key on the
PSB 2000 series power supply unit. (This key
serves as the FAST, LOCK and LOCAL keys.) The
PSB 2000 series power supply unit always resides
in the local, remote, or remote with local lockout
state.
Local The PSB 2000 series power supply unit enters the
local status in either of the following cases:
 When power is turned on.
 When the FAST key is pressed and the LED on
the side of the key is lit.
 When the unit receives the GTL command.
 When the remote status is canceled.
Remote The PSB 2000 Series power supply unit enters the
remote status when it is specified as the listener in
the condition where REN is true. The LED display
goes into the remote display mode, where any panel
keys other than the POWER switch and FAST key
are inoperative. In the local lockout state, any keys
other than the POWER switch are inoperative, with
the only exception to this is if there is an error.
