11.3.5 PHV Error
Alarming
tips
LOG record Suggestion
Alarm!
high-voltage
transmission
is abnormal,
and images
display
normally!
*** PHV hardware protection, HV_PRN_N (+-100V)
NOTE: The asterisk “***” represents the time. The format is: 2011-6-12
14:15:15, hereinafter.
Cut off the
power supply
after shutting
down the device.
Check the
restoration of the
system.
Otherwise, it is
necessary to
replace PHV
board.
*** PHV hardware protection, PHV_OVP_N (OverVoltage Protection)
*** PHV hardware protection, PHV_OCP_N (OverCurrent Protection)
*** PHV Mode supply voltage error:{PHV-1P;}{PHV-1N;}
{PHV-2P;}{PHV-2N;}{+100v;}{-100v;}{PHV-PROTECTION}.
PHV-1P = [PPP]V, limit = [LLL]V
PHV-1N = [PPP]V, limit = [LLL]V
PHV-2P = [PPP]V, limit = [LLL]V
PHV-2N = [PPP]V, limit = [LLL]V
+100v = [PPP]V, limit = 95~105V
-100v = [PPP]V, limit = 95~105V
{..} represents the type for the current error alarming. It can be omitted.
It is based on the actual alarming information.
[PPP] represents absolute value of current voltage.
[LLL] refers to upper limit of preset voltage.
Restart the
device to check
whether the
system can
restore
again.Otherwise,
it is necessary to
cut off the power
supply after
shutting down
the device. If the
problem still
exists, replace
PHV board.
*** CW Mode supply voltage error:{CW-1P;}{CW-1N;}
{+100v;}{-100v;}{CW-PROTECTION}.
CW-1P = [PPP]V, limit = [LLL]V
CW-1N = [PPP]V, limit = [LLL]V
+100v = [PPP]V, limit = 95~105V
-100v = [PPP]V, limit = 95~105V
{..} represents the type for the current error alarming. It can be omitted.
It is based on the actual alarming information.
[PPP] represents absolute value of current voltage.
[LLL] refers to upper limit of preset voltage.
*** CW-Multiplex Mode supply voltage error:
{CW-1P;}{CW-1N;}{PHV-2P;}
{PHV-2N;}{+100v;}{-100v;}{PHV-PROTECTION;}{CW-PROTECTION}.
