Soft Start - Continuous Use
When power is first applied to the Elite-15 DM i, (the front panel breaker- power toggle must be switched to the "on" position)
the Soft Start feature is activated. There is an audible "clack" when the Elite-15 DM i is first turned on or off. This sound is
produced by the Soft Start circuit's 30 Amp relay engaging or disengaging. There is virtually nothing in the Elite-15 DM i's
construction, design, or componentry to wear over the life time of the product, and there is no power draw from your electric
service meter aside from the LED power indicator, and relay circuits. For this reason the Elite-15 DM i may be left with its
power engaged permanently at a cost of pennies per month.
AC Transient Voltage Surge Suppression and Extreme Voltage Shutdown
Extreme Voltage Shutdown Indicator:
This LED is normally off. It monitors AC wiring faults – for example, accidental connection to an open neutral from a 208 or
240VAC feed (this is a common occurrence if the 15 Amp outlet source is not a dedicated line, but instead has been wired with
a daisy-chained neutral from a homes breaker box). The Series Multi-Stage Protection (SMP) circuit senses voltages that are so
high that operation would be impossible and shuts the power down before damage can occur. Upon initially applying power
to these 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 140V or falls below 85V, it will shut off power to the outlet and the Extreme Voltage LED will light. The circuit
will attempt to re-set automatically within 5 seconds, so manual re-set will only be necessary if there is a permanent wiring
fault.
Protection OK Indicator:
Although the Furman SMP circuit assures virtually maintenance free protection from transient voltage spikes and surges,
nature has a way of occasionally creating electrical forces that are beyond the capabilities of any transient voltage surge
suppression device to absorb without some degree of damage. In the rare instance that this occurs, the blue LED located in
the center of the front panel will dim, even though AC power is present at the unit's outputs. 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 first checking the source
of the problem, and perhaps changing the AC source.
Telco – Satellite – Cable Transient Voltage Surge Suppressors
The Elite-15 DM i features transient voltage surge suppression for both standard telephone lines, as well as cable or satellite
lines utilizing standard coaxial connectors. As these surge suppressors are in-line, they will require an additional cable to
connect from their output to the control device requiring protection.
All in-line surge suppressors feature our exclusive ground contamination free technology. This aids in eliminating audio
buzzing, and the video hum-bars that can result from typical in-line suppressors. Further, our cable and satellite suppressors
are DVR friendly as well as HD digital television ready. Both DC carrier signals as well as high bandwidth signals can pass
through our circuit. In fact the bandwidth is less than 0.1dB loss at 1GHz!
To connect your cabling to these in-line protectors, simply follow the in and out indications marked next to the Telco, Cable
and Satellite connectors.
Note:
It is not possible to make an in-line cable or satellite protector "maintenance-free" as we have accomplished with the 120 VAC line.
