ERROR MESSAGE
DESCRIPTION
LED Status:
Open Ground (when lit)
Check to make sure that the ATS is properly grounded. The green wire
going into the transfer switch should be properly attached to the terminal
block (see installation manual). The other end of the green wire should
be properly grounded to the RV. If there is a voltage difference between
the incoming neutral (white) and the ground (green), the transfer switch
will not allow the contactor to engage. If all of the connections are
correct and this message still displays, then there is a bad ground at the
input power pedestal and a different pedestal should be used. Unit must
be reset manually by turning ON/OFF/ON to clear the fault.
Check the voltage level on the incoming generator lines. If it is outside
of 100-135V, the ATS will protect your RV by not letting the contactor pull
in. Refer to the generator documentation to adjust the incoming voltage
to within acceptable limits.
The transfer switch constantly monitors the incoming frequency to verify
that it is within 55-70 Hz. If it is outside these limits, the transfer switch
will protect the RV by keeping the contactor open. If this error message
occurs on generator power, check the generator documentation to
adjust frequency to within acceptable limits.
This indicates a possible faulty connection on the input power to the
transfer switch. With the power off, verify that all input cables are properly
connected to the transfer switch. Also confirm that the generator circuit
breaker is not tripped. After these steps, measure the voltage on the
incoming generator connection to verify that it is within limits.
With the power off, make sure the connection is correct to the transfer
switch terminals. Reverse polarity occurs when one of the hot leads
(L1) is mis-wired into the neutral (N) terminal. In this condition the
transfer switch will not allow the contactor to close.
LED Status:
Surge (No protection when lit)
This indicates that the metal -oxide varistors (MOVs) have exercised
their protection and prevented a high voltage surge from entering the
RV. Surge protection is no longer present.
