Connection Status Lights
Each multi-color Connection Status Light provides information on the
Miniports’ communication links. There are two LEDs, labeled PRIMARY
LINK and SECONDARY LINK that are associated with the SmartSequencer
link communications system. Each of these LEDs can illuminate Red,
Green, or amber. When a number of Miniports are connected together
via their SmartSequencer link ports, the LEDs will illuminate Green and
occasionally blink as messages are passed between units.
SmartSequencing Note: When there are two or more SmartSequencer
units linked in series, a slowly blinking Green Primary Link LED identi-
fies the Primary Unit. Similarly, a SmartSequencer displaying a solid
Green Primary Link LED would indicate the unit is the last Secondary in
the chain of sequencers. Secondary Units in the middle of the chain will
display both a solid Green Primary Link LED and a solid Green Second-
ary Link LED. The Connection Status Link Indicators will flash accordingly
during power up and power down as SmartSequencer messages are sent
between units.
Green LED status is a sign of good communications. If a Contractor Series
unit is used independently (no connections) and the unit is configured as
a Primary Unit (DIP 8, ON or UP), the Primary Link LED will slowly blink
Green at 1 second intervals. If there is a SmartSequencer link connecting
a Primary Unit to a Secondary Unit, the Primary unit will send messages
to the Secondary Unit and the Secondary Link LED will illuminate Green
on the Primary Unit, indicating there is an established communication
link with a the Secondary Unit. On Secondary units (DIP Switch 8, OFF or
DOWN), the Primary Link LED will be Green, indicating there is communi-
cation to a Primary.
The Red Connection status LED can sometimes illuminate briefly if a
message is lost corrupted on the SmartSequencing link. Unless the Red
LED is illuminated continuously, this should be no cause for concern. The
SmartSequencing protocol is robust and redundant. As long as a physical
link is in place, the message will eventually get through.
A continuous Red Connection Status LED indicates that a unit has no
SmartSequencing link connection where the unit has been configured to
expect link communications. This occurs when a Secondary Unit cannot
communicate with surrounding units in a SmartSequencing chain. The
result is that the Secondary Units Primary Link LED may be Red because
the link is broken to a Primary Unit or the Secondary Link LED may be
Red because the link is broken to a Secondary Unit. This could also
mean that the Secondary Unit sees the Primary Unit, but the Primary Unit
does not see its Secondary.
The Amber LED may be seen upon start up initialization or as communi-
cation ensues between Smart Sequencers. This Amber LED state should
resolve to a Red or Green state. If the amber indication does not resolve,
please contact Furman Support.
Power Indicator
One POWER LED is provided to indicate the ON or OFF state of the power
outlet. If power is provided to the outlet, the LED will illuminate green. If
the Miniport is operating under safe power conditions and no utility fault
conditions exist the POWER LED will remain steadily lit. Once triggered to
power-down the POWER LED will go off as the power outlet is deacti-
vated.
EVS LED
The EXTREME VOLTAGE LED indicator is normally OFF. The EVS function
is tied to this LED and monitors the incoming voltage for out of tolerance
conditions. If enabled, the EVS will disable the AC power before damage
can occur. The EXTREME VOLTAGE LED will be illuminated Red anytime
the voltage is found to be below 77 volts or more than 145 volts. The
EVS LED will remain illuminated, and the outlets will be disabled as long
as an out of tolerance condition exists.
CN-15MP
If the combined current, drawn by all devices plugged into the CN-15MP
exceeds 15 Amps at any time, the circuit breaker will “trip’, cutting off
power to all connected devices. If this occurs; the operator must reduce
the load by unplugging one or more devices from the CN-15MP, and reset
it. The operator can reset the circuit breaker by pressing in the circuit
breaker button. However, because the safety feature is a thermal breaker,
it is suggested that you wait one minute after the “trip” occurs to allow
the breaker to cool down before resetting.
CN-20MP
The CN-20MP does not have an integral circuit breaker and relies on
the branch circuit breaker to limit the current to the loads. The CN-20MP
must be connected to a branch circuit equipped with a 20 Amp breaker,
and capable of sustained 20 Amp service. If the branch circuit breaker
trips, the operator must reduce the load by unplugging one or more
devices from the CN-20MP.

The CN-15MP is equipped with a 15 Amp thermal circuit breaker button
which will pop outward if the amount of current distributed to all loads
exceeds 15 Amperes. The CN-20MP does not have a circuit breaker.
