Furman Sound PL-PRO E II - Manual (Page 9)

SERIES II 16 AMP POWER CONDITIONERS
Protection OK Indicator:
Although the Furman SMP+ circuit assures
virtually impregnable protection against
transient voltage spikes and surges, Nature
occasionally creates electrical forces that
are beyond the capacity of any TVSS device
to absorb without incurring some degree of
damage. In the rare instance that this occurs,
the green “Protection OK” LED indicator
located on your front panel will dim. Some
level of protection from voltage surges will
remain, but the clamping voltage rating will
be compromised. The unit must be returned
to Furman Sound or to an authorized Furman
Service center for repair.
NOTE: If the mains power is above the high
cutoff voltage and has caused the unit to
remove power from its outlets, it cannot restore
power until the operator manually turns the unit
off, then on again. Before turning the unit back
on, always check the source of the problem,
and change the AC source if necessary.

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 270
– 280 volts, causing power to the unit’s outlets
to be shut down. Additionally, 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.
