Retractable Rack Lights, Rear Panel Lamp and Dimmer Control:

The PL-8 II, PL-Plus, and PL-Plus D II utilize a dimmer control for the two retractable front panel light tubes. The dimmer knob controls the brightness of both light fixtures. Turn

it clockwise to increase brightness; turn it counterclockwise to decrease brightness. When the lights are not in use, we recommend turning the dimmer fully counterclockwise to maximize the life of the LED’s, however, this is not absolutely necessary. Whether the light tubes are retracted or flush with the front panel, there will be no appreciable heat regardless of dimmer setting due to the efficiency of our full light spectrum LED’s.

All Series II units feature a rear rack BNC socket which will accept any 12 VAC (0.5A) gooseneck lamp assembly, (such as the Furman GN-LED or GN-I). 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.

Multi-Segment LED voltmeter:

(PL-Plus II only)

This three-color, 20-LED bargraph is an accurate, self checking AC voltmeter that continually measures normal voltages. The meter reads from 90 to 128 volts in 2 volt increments (PL-PLUS E II: 180 to 256 volts, in 4 volt increments). The normal range voltages are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively. The voltmeter provides three special flashing patterns to indicate abnormal conditions.

(1)If only the single leftmost (beneath the 90V mark – 180V for E version) LED flashes, the input voltage is marginally low.

(2)If all of the LED’s on the voltmeter flash, the input voltage is marginally high. Power to the PL-Plus’s outlets will remain unless the incoming voltage rises above the Extreme Voltage

Mains Vltg.	Voltage Status	Voltmeter Reading	Outlets
80-90	Low Marginal	The LED beneath the 90V mark flashes	ON
90-104	Low	Meter Reads in Low Red	ON
106-108	Medium Low	Meter Reads in Low Yellow	ON
110-120	Normal	Meter Reads in Green	ON
122-124	Medium High	Meter Reads in High Yellow	ON
126-128	High	Meter Reads in High Red	ON
130-140	High Marginal	All Meter LEDs Flash	ON
Above 140	Extreme (Shutdown)	Meter off—Extreme Voltage LED illuminates OFF
