System Power Output Level:
Red
Red - Fault Condition
When the
SYSTEM POWER OUTPUT LEVEL
turns
red
(arrow on the right end of the bar graph),
there is
an overload condition that disables generator operation.
See
J
in Figure 8-2 below.
Overload
When an overload occurs, it will automatically reset
when the next ultrasound activation signal begins. If the
condition persists:
Place the generator
OFFLINE
and:
1. Check the system: including cables, the acoustic
stack, mounted probe, and/or hand probe. Replace
existing components with ones you know are reli-
able.
2. Place the generator
ONLINE
, and see if the fault
condition has been corrected.
Over Temperature
When the system overheats, there is an over temperature
condition that will cause the fault,
SYSTEM
OVERTEMP DETECTED
. (Fault status is indicated
on the LCD screen. See Table 8-I.)
When the system cools, the system automatically
resets.
Generator Fault Does Not Reset
When the system does not automatically reset, the
generator needs servicing.
System Power Diagnostic
Procedures
AC Line Fault
If Power Status indicator (
B
in Figure 8-3 below)
flashes RED at a fast rate of about four flashes per
second:
• Check AC line voltage level – either an over/under
voltage is sensed.
• Do not call service. Measure the voltage level at
the AC outlet which is probably the source of the
problem.
(
Call service only if the AC line voltage is within
the specified limits.
)
DC Bus Fault
If Power Status indicator flashes RED at a slow rate of
about one flash per second:
• This is normal for 10 to 15 seconds after power is
switched ON.
• If flashing does not stop – a DC bus fault is sensed
– call service.
