damaged.
2. The measurement
circuit of the
DC/DC (rear)
module is
abnormal.
replace the
DC/DC (rear)
module board
that has
protection
occurred.
SOCP(*)
Means the Source
Mode output current
of the DC/DC (rear)
module is over the
limit. 1. The output
current is too high
(protection
occurs when the
module current is
over 44A.)
(Source Mode)
2. The measurement
circuit of the
DC/DC (rear)
module is
abnormal.
1. Remove the UUT
and check if the
operation is
correct.
2. Check and
replace the
DC/DC (rear)
module board
that has
protection
occurred.
LOCP(*)
Means the Regen
Mode input current
of the DC/DC (rear)
module is over the
limit. 1. The input current
is too high
(protection
occurs when the
module current is
over 44A.).
(Regen Mode)
2. The measurement
circuit of the
DC/DC (rear)
module is
abnormal.
1. Remove the UUT
and check if the
operation is
correct.
2. Check and
replace the
DC/DC (rear)
module board
that has
protection
occurred.
IL_SHARE(*)
Means the current
flow in the DC/DC
(rear) module is
uneven. 1. The difference
between the
measured current
the DC/DC (rear)
module is 5A
2. The measurement
circuit of the
DC/DC (rear)
module is
abnormal.
1. Remove the UUT
and check if the
operation is
correct.
2. Check and
replace the
DC/DC (rear)
module board
that has
protection
occurred.
SENSE_FAULT(*)
Means the output
voltage of the
DC/DC (rear)
module is detected
abnormally. 1. The DC/DC (rear)
module output
voltage sense is
reversed.
2. It occurs when the
load line loss is
over 30V.
3. The measurement
circuit of the
DC/DC (rear)
module is
abnormal.
1. Remove the UUT
and confirm if
the voltage sense
wiring of output
terminal is
correct.
2. Check if the load
line loss is over
the limit.
3. Check and
replace the
DC/DC (rear)
