205-UNS Before activation:
The banner between the port icons displays
“NETWORK SIGNAL NOT DETECTED.”
After activation:
All you will see is the code listed on Help >
Station Codes.
Unknown Network Signal - The
gateway station is unable to establish
a network connection on AT&T/
Verizon (US) or Rogers (Canada).
Ensure the station is receiving an
adequate signal strength from the
cellular network. To do so, display the
Service menu*, then:
• Check the network signal
for each type of modem by
choosing: Basic mode > Display
last measured RSSI. The strength
of the signal should be A, B,
or C.
• If the network signal is Grade
D, or if a better network signal
is available on the other type
of modem, change modems by
choosing: Basic mode > Change
modem technology (CDMA or
GSM).
If the signal strength is either
weak (D) or not available for both
CDMA and GSM, arrange for cellular
repeaters to be installed near the
installation site.
If the error persists when the station
shows a strong network signal, call
ChargePoint Customer Support at
1-877-850-4562.
*To display the station’s Service
Menu, scan your ChargePoint Service
card (if the station is activated) or, if
the station is not activated, press the
three station buttons as described on
page B-3.
206-FLC Before activation:
After activation:
You will see the code listed on Help > Station
Codes and the port status icons will show:
n = the number of the applicable port
or
Floating Line Connection - The
voltage of an AC input line has fallen
below 80 volts AC relative to ground.
Even if the line to line voltage
measures nominally 208 or 240 volts,
the voltage of each line must be
greater than 80 volts when measured
to ground.
The two most common causes of a
Power Line Fault are:
• A poor connection in the wiring
supplying power and the ground
connection to the station. There
could be a poor connection
between the buss bar and circuit
breaker, the breaker to the branch
circuit feeding the station, or
at any splice along the branch
circuit.
• The station is connected to
an incompatible improperly
grounded power source. All power
and ground connections must
be clean and tight and carry the
full rated current of the station.
Do not connect the station to an
ungrounded (floating neutral)
system, a corner grounded Delta
system, or the high (or “stinger”
leg) of a center grounded Delta
system.
Correct any faulty connections.
Verify that the station is connected
to a system with its neutral properly
grounded according to NEC Article
250.
Verify the station is connected to
one of the system types described in
Chapter 1.
If the error persists, call ChargePoint
Customer Support at 1-877-850-
4562.
