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.
