User manual FURMAN PS8 R II

[. . . ] Additionally, Furman's trusted over-voltage circuitry protects against all too frequent accidental connections to 208 or 240 VAC, by shutting off the incoming power until the over voltage condition is corrected. [For E versions: Furman's SMP+ clamps at 376 VpK, (266 VAC RMS. )] 1 PS-8R II - POWER CONDITIONER / SEquENCER lIft (linear technology) f i lt e r i n g Traditional AC filter - conditioners have been designed for unrealistic laboratory conditions. Prior technologies, whether multiple pole filter or conventional series mode, could actually harm audio and video performance more than they help, due to the resonant peaking of their antiquated, non-linear designs. under certain conditions, these designs can actually add more than 10 dB of noise to the incoming AC line! [. . . ] Simply slide the BNC plug over the socket and rotate clockwise until the connector snaps into the locked position. The rear rack lamp can be powered on or off with the rear light power switch located on the far left of the front panel. The Series II's front panel lED lamps must be replaced by qualified Furman service personnel. reMote swItchIng (PS-8R II & PS-8R II E) In the most basic configuration, only two wires and an SPST switch are needed to initiate remote ON or OFF sequence. The switch may be either a momentary or maintained-contact type. If a third & fourth wire are used, an LED may also be installed at the remote end to indicate that the power is on. MAINTAINED VS. MOMENTARy CONTACT SWITCHING Maintained switches, such as most toggle switches and push-on/push-off switches (including the Furman RS-1), stay open until switched and then remain closed until switched again. Momentary switches, usually pushbutton types like the Furman RS-2, are normally open and stay closed only as long as the button is pressed. An on-off switch of either kind may be used to actuate the PS-8R II's remote operation. 4 PS-8R II - POWER CONDITIONER / SEquENCER Maintained switches are generally most convenient when there is only one remote location. When more than one switch location is required, momentary switches allow the sequence to be started from different locations. PS-8R II main circuit board has 5 pairs of terminals (PCB REV F and later) labeled as: JMP1 (REM TO +12V = OFF, DEFAuLT ), when the REM and +12V terminals are tied together, the PS-8R II will sequence OFF.
