Indicators
Extreme Voltage Shutdown Indicator
Extreme Voltage Shutdown Indicator
The AC Series SMP+ circuit senses voltages
that are high enough to cause damage to your
components, and shuts the power down before
damage can occur.
The Extreme Voltage Shutdown LED is
normally off. If an input voltage in excess of
137VAC [or 270 VAC for the AC-210 E] is
sensed, either on initial power-up or during
normal operation, the AC-215 / AC-210 E 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 cannot 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.
Protection OK Indicator
Although the Furman SMP+ circuit assures
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 turn off. 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.
Troubleshooting
Symptom: No power to the AC outlets.
Possible Cause: Circuit breaker has
tripped due to excessive load.
Action Needed: Unplug one piece of
equipment from the AC-215 / AC-210
E, and push the re-set tab into the
Circuit breaker bezel.
Symptom: No power to the AC outlets, even
after the Circuit breaker has been re-set.
Possible Cause: Protection devices
are damaged.
