TROUBL E SHOOTING GUIDE

1.) Symptom: No power to the AC outlets.

Possible Cause: Circuit breaker switch has tripped to the off position, due to excessive load.

Action Needed: Remove one piece of equipment from the Series II unit, open the hinged switch / breaker cover, and reset the switch to the on position.

2.) Symptom: No power to the AC outlets, “Protection OK” indicator is not lit.

Possible Cause: Either the AC outlet to which your Series II device is connected has no AC voltage present, or the unit has been subjected to a sustained voltage in excess of 400 Volts.

Action Needed: Plug the Series II unit into an AC receptacle where AC voltage is present. If the problem persists, the protection circuit may be damaged, and require factory service.

3.) Symptom: Extreme Voltage indicator lit.

Possible Cause: Input voltage is above 135- 140 volts (270 – 280 volts E version), causing power to the unit’s outlets to be shut down.

Additionally, if the voltage is below 85 - 90 volts at turn on, the unit will not allow AC voltage to reach the outlets.

Action Needed: Correct the line voltage, then; turn the unit on. Consider installing a Furman voltage regulator.

DEFINITIONS

SPIKE: This is a pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. Though they are usually of very short duration, the energy they

contain can be considerable, enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and degrade wiring insulation. They are an unavoidable component of electric power. They are caused unpredictably by electric motors switching on or off (on the premises or outside), utility company maintenance operations, lightning strikes and other factors. Spikes (also called surges or transients) are absorbed by special components in the series II Series Multi-Stage Protection Plus circuitry to provide safe voltage levels to protect your equipment.

RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower voltages and less energy than is found in spikes, but it is continuous rather than transient in nature.

It is not likely to cause damage, but it can certainly be annoying, producing static in audio circuits, “snow” on video screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters, certain kinds of lighting, electric motors, and other sources. Because noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be effectively reduced through use of low- pass filtering.
