ASD-120 SEQUENCED POWER DISTRO

Remote Operating Modes
If the ASD-120 will be controlled locally only, you may skip this section and the
next section of the manual.
There are three remote operating modes available: Maintained Mode/Normally
On, which is the default, Maintained Mode/Normally Off, and Momentary Mode.
The Momentary Mode on the ASD-120 shares the same characteristics as the
Momentary Mode on the Furman PowerPort, MiniPorts, PowerLink and PS-PRO
and PS-8R Power Sequencers. Remote inputs (REM, FORCE ON, FORCE OFF)
are controlled by applying at least 5 VDC or 6 VAC between the input and the REM
COM terminal.
This is the default control logic on all of our existing and past power products.
However, the ASD-120’s inputs are enhanced in the following ways: (1) They are
polarity independent, and work with positive, negative or AC control signals.
(2) They are optically isolated. The remote control inputs have a floating common.
(3) They safely accept up to 130 VAC, for direct control from mains supply.
Maintained Mode/Normally On (Default)
In the absence of any signal applied to the remote input, the ASD-120 will se-
quence on as soon as power is applied, and the key switch is turned to REM
or ON. This is Maintained Mode/Normally On. In this mode, voltage must be con-
tinually applied to the REM input to keep the ASD-120’s outlets off, when the key
switch is in the REM position. This mode is compatible with all other Furman prod-
ucts’ REM inputs.
