Programmable Bidirectional DC Power Supply 62000D Series
Operating and Programming Manual
B-8
AD_PWM_BOT_FAULT(*)
Means the internal
power components
of AD/DC module
are shorted. (Latch) The bottom power
component on the
AC/DC module is
abnormal or
damaged. replace the
AC/DC module
board that has
protection
occurred.
AD_HARD_ERR(*)
The front stage
module in the device
has triggered a
protection. This
message is used to
stop the normal
module from output.
(Latch) 1. One of the AC/DC
modules in the
device has
protection
occurred.
2. A certain AC/DC
module message
or measured
value cannot be
found in the
device.
1. Check and
replace the
AC/DC module
board that has
protection
occurred.
AD_MEM_ERR(*)
Means the DSP
memory on AC/DC
module digital board
is abnormal. (Latch) The AC/DC module
digital board DSP
memory is abnormal. Check and replace
the digital board.
DD_LLC_STARTFAIL(*)
Means the start of
DC/DC (front)
module is failed, and
the DC BUS voltage
is out of
specification. (Latch) 1. The measurement
circuit of the
DC/DC (front)
module is
abnormal.
2. The PWM drive
signal of DC/DC
(front) module is
abnormal.
3. The power
components of
DC/DC (front)
module are
abnormal or
damaged.
1. Remove the UUT
and check if the
operation is
correct.
2. Check and
replace the
AC/DC module
board that has
protection
occurred.
DD_SHORT(*)
Means the primary
side transient of
DC/DC module has
over current. (Latch) 1. The LC board is
unlocked or not
secured.
2. The output
terminal of the
DC/DC module is
shorted.
3. The top and
bottom leg of
secondary side
switch on DC/DC
module are
shorted.
1. Check if the LC
board is fully
locked.
2. Check if the AD
module output or
the back-end
UUT is shorted.
3. Measure if the
MOS switch of
the DC/DC
module is
broken.
DD_IP_OCP(*)
Means the internal
transient of DC/DC
(front) module has
over current.(Latch) 1. The output
transient power is
too high (the IO
module is over
51A peak that has
1. Remove the UUT
and check if the
operation is
correct.
2. Check and
