Metered Six Series Owner's Manual INTRODUCTION Thank you for your purchase of a Furman Metered Six Power Conditioner, and congratulations on your choice. The Metered Six line of Power Conditioners offer many of the same features that have made Furman Power products preeminent within the music, broadcast, and contractor industries for decades. Now, many of our standard features such as triple stage surge suppression, retractable rack lights, over-under voltage shutdown, and multi stage RFI/EMI filtering, are available with laboratory quality Digital Voltage and True RMS Current meters. Your Metered Six unit provides comprehensive protection from power line-related transient voltages and noise, while the 20 amp capable PRO units provide additional protection from wiring faults common to remote power, theaters, convention centers, and AC generators. The Metered Six's fastacting suppression circuit responds in less than a nanosecond, clamping transient voltages to safe levels. The RFI/EMI filter works to prevent the noises generated by fluorescent lights, lighting dimmers, radio transmitters, and electrical appliances from contaminating the AC line and from there, leaking into sensitive audio, video, or computer circuits. 2 SAFETY I N F O R M AT I O N To obtain best results from your Furman Metered Six Power Conditioner, please be sure to read this manual carefully before using. 5. Route the power cord and other cables so that they are not likely to be walked on, tripped over, or stressed. Pay particular attention to the condition of the cords and cables at the plugs, and the point where they exit your Metered Six unit. To prevent risk of fire or injury, damaged cords and cables should be replaced immediately. 6. Clean your Metered Six unit with a damp cloth only. Do not use solvents or abrasive cleaners. Never pour liquid on or into the unit. 7. Your Metered Six unit should be serviced by qualified service personnel when: · The power supply cord or the plug has been frayed, kinked, or cut. · Objects have fallen or liquid has spilled into the unit. · The unit has been exposed to rain or other moisture. · The unit does not appear to operate normally or exhibits a marked change in performance. · The unit has been dropped, or the enclosure damaged. WARNING To reduce the risk of electrical shock, do not expose this equipment to rain or moisture. Dangerous high voltages are present inside the enclosure. Do not remove the covers. Other than the light bulbs, there are no user serviceable parts inside. Refer servicing to qualified personnel only. The lightning flash with an arrowhead symbol, (within an equilateral triangle) is intended to alert the user to the presence of un-insulated dangerous voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock. I M P O R TA N T SAFETY INSTRUCTIONS (Please read prior to installation) 1. Please read and observe all safety and operating instructions before installing your Metered Six unit. Retain these instructions for future reference. 2. Your Metered Six unit should not be used near water ­ for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, etc. 3. Do not place your Metered Six unit near heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. 4. The PL-PROD, PL-PRODM, and PM-PRO should only be connected to a 120 VAC, 60Hz, 20 amp grounded electrical outlet. Outlets wired for 20 amps, may be identified by the T-shaped socket opening that accept the perpendicular blades of the PRO unit's power plug. If you don't have a 20amp outlet, have one installed by a qualified electrician. Do not defeat the ground or change polarization of the power plug. 8. Your Metered Six unit requires that a safety ground be present for proper operation. Any attempt to operate the unit without a safety ground is considered improper operation and could invalidate the warranty. 9. Light bulbs are the only user-serviceable parts in the PL-PLUSD, PL-PLUSDM, PL-PROD, and PLPRODM. Instructions for replacing them are on page/s 4, 5, 6, and 7. The light tubes and end caps become quite warm to the touch in normal operation. To avoid burning your fingers, allow the cap to cool completely before unscrewing it. If you find that the heat from the tubes is excessive, reduce the dimmer knob setting. 10. Do not attempt to service your Metered Six unit beyond what is described in this manual. All other servicing should be referred to qualified service personnel. 3 O P E R AT I O N Retractable Rack Lights and Dimmer Control: The PL-PLUSD and PL-PLUSDM 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. Light Tubes and Bulb Replacement: The PL-PLUSD and PL-PLUSDM feature the familiar slide-out rack lights pioneered by Furman. These units' lamps come supplied with five-watt night light bulbs. Replacements are available at most hardware stores, and may be purchased from Furman Sound service as well. F E AT U R E S The PL-PLUSD features an advanced digital voltage meter, while the PL-PLUSDM and PM-8DM provide a laboratory grade True RMS digital voltage and current meter. Both meters are located at the center-front panel of their respective units. A 15 amp circuit breaker is mounted on the front panel, allowing quick, convenient power restoration. Simply pushing the square center tab into the front bezel will re-activate the breaker after an excessive current load has tripped it. The rear panel contains eight switched AC outlets to power your equipment, (4 for analog equipment and 4 with additional filtering for digital ­ computer components, see below). These AC outlets are spaced to accommodate up to four plug-mounted power supplies ("wall warts"). Power is delivered to the unit by a heavy duty 14 AWG AC cord, 10 feet (2.4 m) in length for extra reach and durability on stages and other high-traffic areas. BULB REPLACEMENT Bulbs are easily replaced without removing the unit from the rack. Here's How: First, pull the light tube(s) all the way out. Unscrew the cap on the end of each tube to get access to the bulb. (Be careful not to push the tubes in after you have removed the caps.) To unscrew the bulb, place your index finger across the hole on the underside of the tube and in contact with the bulb. Use the ball of your finger to rotate the bulb out of its socket. Then remove the bulb from the front of the light tube. Put a new bulb in the tube, rotate it with your finger from the hole in the bottom of the tube and replace the light tube cap(s). NOTE: The caps and light tubes become quite warm to the touch in normal operation. To avoid burning your fingers, allow the cap to cool completely before unscrewing it. If you find that the heat from the tubes is excessive, try reducing the dimmer knob setting. As an alternative, you may substitute four-watt bulbs or even colored Christmas tree bulbs. The Tape Trick: In cases where the bulb is still warm, or too tight to unfasten with your fingers, a piece of duct or gaffers tape about 2 inches square can aid in the bulb removal. Simply pinch about a quarter inch of the center portion of tape together, and place the remaining portion of the adhesive backing on the exposed portion Analog Component Plugs 4 Digital Component Plugs of the bulb. The pinched center section allows some leverage for unscrewing of the bulb, and the tape provides some insulation from the heat. On/Off Rocker Switch: This 15 amp capacity power switch is specifically designed to stand up to the enormous high inrush current demands placed by many Power Amplifiers. Additionally, the semi-transparent rocker lights when switched to the "ON" position. O P E R AT I O N CON'T TROUBLE SHOOTING Symptom: Digital Voltmeter: The PL-PLUSD's digital voltmeter continuously measures incoming AC voltages with extraordinary accuracy (+/- 1VAC). The meter reads from 45 to 141 volts in 1-volt steps. Digital Volt / Current Meter and Meter Switch: The PL-PLUSDM and PM-8DM True R.M.S. digital volt / current meter continuously measures incoming AC voltages with laboratory accuracy (+/- 1VAC). The meter reads from 45 to 141 volts in 1-volt steps. Additionally, when their meter switch is set in the current mode, it will measure the full AC load circulating through either the PL-PLUSDM, or PM-8DM, (+/- 0.1Amp). Because of the True RMS circuitry employed, variable AC line distortions will not affect the accuracy of either measurement. NOTE: The PL-PLUSD, PL-PLUSDM, and PM-8DM do not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you may benefit from the use of one of Furman's AC Line Voltage Regulators. GUIDE No power to the AC outlets. Possible Cause: Circuit breaker has tripped due to excessive load. Action Needed: Remove one piece of equipment from the Metered Six unit, and push the square re-set tab into the Circuit breaker bezel. No power to the AC outlets, even after the Circuit breaker has been re-set. Symptom: Possible Cause: Protection devices are damaged. Action Needed: Factory service.
