outlet with a protective earth ground connection Introduction Important Safety Insructions Features PS-8RE III - POWER CONDITIONER / SEQUENCER2 AV equipment is most vulnerable and susceptible to dam- age during those first few milliseconds after the power is turned on or off. When audio amplifiers are powered on, a large inrush current occurs as the large capacitors in the power supply charge. This inrush can be on the order of several hundred amps for a number of AC cycles. If more than one amplifier is connected to a single branch circuit, the inrush current is multiplied and can cause the circuit breaker to trip, or the line voltage to sag. Additionally, if the amplifier is pow- ered on either before or concurrent with signal processing equipment, the result can be a dreaded speaker “pop”. This all-too familiar noise occurs as transients from the signal processing equipment flow uncontrolled to the inputs of the power amplifier. The amplifier amplifies this signal and passes the transient “pop” along to the speakers. The result can be catastrophic to both speaker and amplifier. Powering down A/V is equally as perilous. Unlike other A/V equipment, the large capacitors found in amplifiers will store their charge. This means if signal processing devices and amplifiers are switched off simultaneously, the amplifiers are still operational as the signal processing equipment is switched off. Just as with startup, the power down phase can cause equipment to emit transients which are amplified by the amplifier, then propagated to the speakers and “pop”! AC Power sequencing addresses these problems by pow- ering up your equipment in stages. The signal processing equipment is powered on first and allowed to stabilize, and then the amplifiers are powered on. The first stage signal processing equipment may still emit transient noise upon power up, but because the amplifiers have yet to power on, the transient signal passes without incident. Power sequencing stages the activation of heavy loads, which prevents nuisance breaker trips and equipment damage due to line sags and brown-outs. This means that inrush currents are offset in time, rather than occurring simultaneously. This can also be advantageous to upstream equipment if the sequencer is supplement- ing other power management such as a UPS or voltage regulator. The Furman PS-8RE III provides three delay stages. If three stages of power sequencing are not enough for your application, you can chain together multiple PS-8RE III sequencers. For best results we recommend that your power amplifiers always receive power last. Plug the am- plifiers into DELAY 3, or divide them into two groups and plug one group into DELAY 2, and the other into DELAY

3. The low level equipment feeding the amps, such as

mixers and signal processors, should plug into DELAY 1 such that they will turn on and stabilize first. The turn-on delay intervals are factory preset to 5 seconds per stage. This delay can be increased or decreased us- ing the rear panel trim pot adjustment (see “Adjusting the Delay Interval” for details). In the event of a power outage, all equipment plugged into the PS-8RE III will lose power simultaneously. When power is restored, the behavior of the PS-8RE III will depend upon switch settings and how the unit has been configured:

• If the PS-8RE III has been configured for Maintained mode and the Sequence switch is in the ON position, the delayed outlet groups will turn on in the normal delayed sequence when power is restored.

• If the PS-8RE III has been configured for Momentary mode the delay outlets will remain off until activated by the end user. Sequenced Outlets SMP+ (Series Multi-Stage Protection Plus) Unique to Furman’s SMP+ is its unparalleled clamping volt- age. While other designs offer clamping voltages that are well above 660 Vpeak, the SMP+ clamps at 376 Vpeak, (266 VAC RMS). This unprecedented level of protection is ONLY available with Furman’s SMP+ technology. Fur- man’s trusted over-voltage circuitry protects against all too frequent accidental connections to 408 or 440 VAC by quickly disconnecting the loads from the incoming power until the over voltage condition has been corrected. Furman’s SMP+ surge suppression virtually eliminates service calls. Traditional surge suppression circuits “sac- rifice” themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system, and repair of your surge suppressor. With Furman’s SMP+, however, damaging transient voltages are safely absorbed, clamped, and dissipated. PS-8RE III - POWER CONDITIONER / SEQUENCER3 LiFT (Linear Filtering Technology) SEQUENCE

220-240V 50/60Hz 10A MAX Front Panel Features Power Indicator The POWER indicator is illuminated any time power is applied to the PS-8RE III. Traditional AC filters - 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. This is 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! Worse still, lost digital data, the need to re-boot digital pre- sets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman’s SMP+ with LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground. Rear Panel Lamp ON / OFF Switch PROTECTION OK Indicator: Although the Furman SMP+ Filter assures protection from transient voltage spikes and surges, nature can oc- casionally produce electrical forces that are beyond the capabilities of any surge suppression device to absorb without sustaining some degree of damage. In the rare instance where this occurs, the green “PROTECTION OK” LED indicator located on your front panel will either dim or extinguish completely. If this happens, the PS-8RE III’s surge protection capability has been compromised and the unit must be returned to Furman Sound, or an authorized Furman service center for repair. DELAY 1, 2, and 3 Indicators The DELAY 1, 2, and 3 indicators always show the pres- ent state of the corresponding DELAY 1, 2, and 3 outlets. In all cases, if the indicator is ON, the outlet is ON. If the indicator is OFF, the outlet is OFF. EVS Indicator The EXTREME VOLTAGE (EVS) LED indicates the state of the EVS detection system. This LED is normally off, but illuminates Red when an EVS error has occurred. If the PS-8RE III encounters a line voltage above the EVS threshold (275 VAC) the SMP will disconnect the power from the rear panel outlets and the EVS LED will activate. The EVS LED will extinguish and power will be restored when the line voltage returns to normal conditions.4 Delay Adjustment The delay interval, which is the time between the turn-on / turn-off of consecutive delay outlets 1 and 2, or 2 and 3, is factory preset to approximately 5 sec- onds. It is possible to lengthen or shorten the delay interval by changing the position of the DLY-ADJ trim pot located on the right side of rear panel.

Rear Panel Features Full CCW ½ Second 12 o’clock 5 Seconds Full CW 10 Seconds DLY-ADJ Position Stage Delay The delay adjustment procedure is simple and re- quires a small standard screwdriver. The DLY ADJ (delay adjustment) is a trim pot that is located on the rear of the PS-8RE III above the legacy interface and to the left of the DIP Switches. Locate the rectangu- lar slot in the center of the trim pot and use a screw- driver the rotate the trim pot to set your desired delay The minimum delay (1/2 Second) is achieved when the trim pot is adjusted fully counter-clockwise. The maximum delay (~10 Seconds) is achieved when the pot is rotated fully clockwise. Sequencing On/ Off Switch This switch enables the power sequencing capabili- ties of the PS-8RE III. This is NOT the power On/Off switch. Front Panel Covenience Outlet Switched IEC C-13, 10A maximum. Thermal Circuit Breaker The overall current capacity of the PS-8RE III is 10 Amps. This refers to the combined steady-state current drawn by all devices plugged into all nine of its outlets. If the combined steady-state current level exceeds 10 Amps, the circuit breaker may trip, cutting off power to your con- nected equipment. If this occurs, you must reduce the load by unplugging one or more devices from the PS- 8RE III. Then push the button on the front panecircuit breaker to reset it. Although 10 Amps is an absolute limit, the PS-8RE III’s power sequencing capability will allow you to come as close as possible to using the full 10 Amps, because the risk of tripping the breaker is greatly reduced by sequencing on loads, thus allowing each stage to settle to its steady-state current draw before the next stage is powered.

Delay 1, 2 and 3 Outlets Banks Sequenced: Sequencing Enabling On/Off Switch on Front Panel5 in “Legacy” mode by feeding the +12VDC signal back into the REM terminal input; which is pin #3 on the same connector. PIN 2 STATUS (Output) The STAT (status) terminal is an output that may be used to activate an LED to indicate the status of the PS-8RE

III. If the STAT terminal is high, the PS-8RE III Delay out-

lets are either ON, or are in the process of sequencing ON. If the STAT terminal is low, the PS-8RE III Delay outlets are OFF. To use the STAT terminal output simply connect an LED between the STAT and GND with the Cathode (flat) side of the LED oriented toward the GND pin (Pin #4). Do not use a series current limiting resis- tor. If the LED does not light when the remote switch is ON, check the polarity of the LED and reverse the leads if necessary.

• If the LED is OFF, the DELAY outputs are OFF

• If the LED is ON, the DELAY outputs are ON

• If the LED is blinking, the DELAY 1,2 or 3 outputs are in transition either from ON to OFF or OFF to ON PIN 3 REMOTE (Input) The REM (remote) terminal is provided to allow remotely connected devices to sequence the PS-8RE III ON or OFF. The REM terminal has been designed to work with voltages from 5 to 30VDC. Filtering has been added to this input to prevent false triggering. The behavior of the PS-8RE III is controlled by the combination of the signal presented at the REM terminal input, and the arrange- ment of the rear panel DIP switches. Please refer to DIP SWITCH section for more details. Rear Lamp Socket The PS-8RE III features a rear rack BNC socket which will accept any 12 VDC or 12VAC up to ½ Amp gooseneck lamp assembly, (such as the Furman GN- LED or GN-I).

Note that the rear lamp socket is powered by 12 Volts DC and is therefore polarized. The lamp connector is polarized center positive (Figure A). If you are using a polarized lamp, please make sure that the lamp is polarized center positive. Most LED and incandes- cent lamps are polarity independent. PIN 1 +12VDC (12VDC Voltage Source) The +12VDC terminal pin is a general purpose, 12VDC voltage source relative to the GND (#4) pin. It is provided to allow the user to control the operation of the sequencer

Fig. A The PS-8RE III has a remote interface which can be used to control the PS-8RE III remotely using a Furman RS-1 (Maintained) or RS-2 (Momentary) wall switches. In the most basic, single unit configuration, only two wires and a switch are required to initiate a remote ON or OFF sequence. The switch may be either a momen- tary or maintained-contact type. If a third & fourth wire are available, an LED “Status Light” can be installed at the remote switching location to indicate the status of the PS-8RE III. The pins on the remote interface are de- scribed below: REMOTE PORT

PS-8RE III - POWER CONDITIONER / SEQUENCER6 PIN 4 GND (Remote Interface Common)The GND (ground) terminal pin serves a ground reference point for all other pins on the Remote Interface. GND can also be fed back into the REM pin (Pin #3) to activate the sequence when the PS-8RE III has been configured for GND ON mode. Please note that the GND terminal on the Remote Interface is not the same as chassis ground.DIP SwitchA rear panel three position DIP switch is used to set the sequence mode (+12V ON, +12V OFF, GND ON, Mom/ Maint) which defines how the PS-8RE III will react to the signal presented on its REM input.

DIP Switch position #1 (Factory default is OFF)DIP Switch position 1 defines how the PS-8RE III will behave when +12VDC is applied to the REM pin on the Remote interface. If this switch is in the ON position, the PS-8RE III will sequence ON when +12V is applied to the REM input. If this switch is in the OFF position (+12V OFF) the PS-8RE III will sequence OFF when +12V is applied to the REM input. DIP switches 2 and 3 must be in the OFF position (Maintained mode) DIP Switch position #2 (Factory default is OFF)DIP Switch position 2 defines how the PS-8RE III will behave when GND is applied to the REM pin on the Remote interface. If this switch is in the ON position, the PS-8RE III will sequence ON when GND is applied to the REM input. If this switch is in the OFF position the PS-8RE III will follow the behavior defined by DIP Switch #1. DIP switch 3 must be in the OFF position (Maintained mode).1 2 3FACTORY DEFAULT SETTING REMOTE PORT

PS-8RE III - POWER CONDITIONER / SEQUENCER7 DIP Switch position #3 (Factory default is OFF) DIP Switch position 3 defines the switching preference for switches or devices connected to the REM pin on the Remote Interface. If this switch is in the ON position, the PS-8RE III will operate in Momentary mode. If this switch is in the OFF position the product will operate in Maintained mode. Maintained switches, for example toggle switches or latching push-ON / push-OFF push button switches maintain their contact position until the switch is actuated a second time. Thus a switch that is closed will remain closed until the switch position is changed. Momentary switches, for example non-latching push button switches, (including the Furman RS-2) are momentary contact devices that maintain their contact position (open or closed) only as long as the switch is held in a given position. When the actuator is released, the switch reverts to its normal position. A switch of either kind may be used to actuate the PS-8RE III’s remote operation. Maintained switches are generally most convenient when there is only one remote switch location used to control the PS-8RE III. When more than one switching location is required, momentary switches, operating in parallel allow the PS-8RE III to be sequenced ON or OFF from multiple locations Multiple PS-8RE III units can be linked together (via their remote interface) to control large AV systems. There are two basic connection methods for the PS-8RE III; Serial and Parallel. The connection method you use may be series, parallel, or a combination thereof and will depend upon the requirements of your specific installation. PS-8RE III in Series Mode Series mode connection is normally used when more than three delay stages are needed. Combining PS-8RE III units in series requires an external 240 VAC coil SPST relay to trigger secondary (downstream) units. When connecting PS-8RE III units in series, the coil of the relay is plugged into one of the DELAY 3 outlets on the primary (upstream) unit. PS-8RE III in Parallel Mode Parallel mode can be used to activate loads in excess of 10 Amps by distributing the loads over one or more PS-8RE III units. When connected in parallel (see figures B and C) all connected PS-8RE III units will activate their DELAY 1 simultaneously. The activation times of DELAY stages 2 and 3 will depend upon the delay setting of each unit. If PS-8RE III units are operating in parallel to increase load capacity, each unit should be connected to an independent AC circuit rated at 10 amps or more. If in doubt, please consult with a qualified electrician to verify that your facility can support the load currents required for your installation. Connecting Multiple PS-8RE III Units Together PS-8RE III - POWER CONDITIONER / SEQUENCER8 Parallel Maintained Mode: To control multiple PS-8RE III units with a single remote switch; connect the REM, +12V, and GND terminals of all units in parallel (Figure B). Make sure that the DIP #3 is OFF and the positions of DIP #1 and DIP #2 on all connected units are set to the same position. Connect a single maintained switch (such as the Furman RS-1) to the nearest PS-8RE III. Parallel Momentary Mode To control multiple PS-8REIII units with multiple switches, use Momentary mode (DIP #3 ON) and connect the REM, and +12V, terminals of all units in parallel (Figure C) and connect one or more momentary contact switches in paral- lel with the REM, and +12V terminals. All connected units will change state (from ON to OFF, or OFF to ON) each time one of the switches are pressed. Helpful Hint: Breaker trips or unauthorized front panel operation can cause units operating in Momentary mode to fall out of sync. To restore sync, press and hold the remote switch (Figure C) for more than 4 seconds. This Fig. B Three PS-8RE III units configured for Parallel Maintained mode with LED indicator.

Linked units can also be re-synced by cycling AC power to all con- nected units. Series Maintained Mode To operate multiple PS-8RE III units in series using a single remote switch; connect a maintained contact switch between the REM and +12V on the primary unit and con- nect a 240VAC coil relay (TE P/N 1649341-2) between the DELAY 3 outlet on the primary unit and the REM and +12V pins on the secondary unit. Continue connecting PS-8RE III units following this same pattern until all units have been connected. When the primary unit sequences ON the relay will acti- vate as soon as the DELAY 3 outlet on the primary unit has been activated. This will cause the secondary unit to begin to sequence on.

• In series mode, the DELAY 3 outlets of the primary unit and the DELAY 1 outlets of the secondary unit will activate simultaneously.

• When sequencing off series connected units, the sec- ondary units will begin to sequence off as soon as the DELAY 3 outlets on the primary unit turn off. This means that both the primary and secondary units will sequence off at the same time. In other words, sequencing ON and sequencing OFF are not equivalent. If your installation requires symmetrical sequencing please consult Furman customer support for other product options. COIL REMOTE PORT12V STAT REM GND12V ON12V OFF GND MOM
