indicator lit, after the main power switch is turned to the on position. If the unit still does not function under these conditions check the circuit breaker button! It is the round black button adjacent to the incoming AC cord. If the circuit breaker trips immediately, there may be too great of a current load placed upon it. Simply disconnect one product at a time until this no longer happens. If the breaker trips with no components connected, there may be a wiring defect that requires Furman service.

Indicators

Extreme Voltage Shutdown Indicator:

Furman’s SMP+ circuit senses sustained voltages that are high enough to cause damage to your components, and shuts the power down before damage can occur. Such conditions can include accidental connection to a 240VAC source (where 120VAC is expected), or an open neutral from a 208 or 240VAC source.

The Extreme Voltage Shutdown LED is normally off. If an input voltage in excess of 137VAC is sensed, either on initial power-up or during normal operation, the PST-8 will shut off power and this indicator will light.

NOTE: If the mains power is above the high cutoff voltage and has caused the unit to remove power from its outlets, it can not restore power without the operator manually turning the unit off, then on again. Avoid turning the unit back on without fi rst checking the source of the problem and perhaps changing the AC source.
