Amp Power Conditioners Owner's Manual

SERIES II 20 AMP POWER CONDITIONERS
units, the Extreme Voltage indicator LED will
light if the input voltage is above the extreme
voltage cutoff, and power will not be applied
to the unit’s outlets. If the unit has been
operating with an acceptable input voltage and
subsequently that voltage exceeds 135V, it will
shut off power to the outlet and the Extreme
Voltage LED will light. (E version: over voltage
shut down is 260 VAC. Guards against open
neutral and accidental connection to 300+
VAC)
Protection OK Indicator:
Although the Furman SMP circuit assures
virtually protection from transient voltage
spikes and surges, nature has a way of
occasionally creating electrical forces that are
beyond the capabilities of any TVSS device to
absorb without some degree of damage. In
the rare instance that this occurs, the green
“Protection OK” LED indicator located on your
front panel will dim. If this happens some level
of protection from voltage surges will remain,
but the Furman’s clamping voltage rating will
be compromised. The unit must be returned
to Furman Sound, or 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 without the operator manually turning
the unit off, then on again. Avoid turning the
unit back on, without rst checking the source
of the problem, and perhaps changing the AC
source.

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.
