Err
Code
Description Possible Cause Things to check Correction
143 The unit or a
mode was never
calibrated
The system or a mode was
never calibrated. The Controller
was replaced but not calibrated.
Calibrate any modes that need
calibration.
Replace the Control/
Display Board if
the system will not
calibrate.
144 RF controller
and Monitor
power levels do
not match
The Monitor and RF Controller
and constantly checking to
ensure they see the same
electrosurgical output power
during activation. This error
occurs if the power they sense
does not match. This typically
results from differences between
the independent Monitor and
RF Controller sensing circuits.
Use DACView to troubleshoot
the Monitor. Verify that the
output power is consistent with
displayed power setting. Check
voltage and current sensing chan-
nels for both the RF Controller
and the Monitor.
Replace the Control/
Display Board.
Troubleshoot the
RF voltage (Vsense)
and current (Isense)
feedback circuits for
the activated mode.
145 Inter-processor
communications
error
The data transmitted from the
System Controller through
the HPI port is faulty. This
could be caused by damage to
components associated with
the HPI bus on the Controller,
permitting electromagnetic
interference to upset one of the
processors.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
150 2.5 volt too low 2.5-volt power on the Control/
Display Board is too low.
Check for proper connection
of the ribbon cable.Check the
+12V entering Control/Display
Board (TP66). Check the +2.5V
power on the Control/Display
Board (TP36). Verify that the
System Controller ADC refer-
ence voltage (C_2.5V) on the
Control/Display Board is 2.5
volts.
If +12V is out of
limits, replace or
repair the Power
Board. If either
+2.5V or the ADC
reference is out of
limits, replace the
Control/Display
Board.
151 2.5 volt too high 2.5-volt power in the system is
too high.
Check for proper connection of
the ribbon cable.
Check the +12V entering
Control/Display Board (TP66).
Check the +2.5V power on the
Control/Display Board (TP36).
Verify that the System Controller
ADC reference voltage (C_2.5V)
on the Control/Display Board is
2.5 volts.
If +12V is out of
limits, replace or
repair the Power
Board. If either
+2.5V or the ADC
reference is out of
limits, replace the
Control/Display
Board.
152 1.2 volt too low 1.2-volt power on the Control/
Display Board is too low.
Check for proper connection of
the ribbon cable.
Check the +12V entering
Control/Display Board (TP66).
Check the +1.2V power on the
Control/Display Board (TP15).
Verify that the System Controller
ADC reference voltage (C_2.5V)
on the Control/Display Board is
2.5 volts.
If +12V is out of
limits, replace or
repair the Power
Board. If either
+1.8V or the ADC
reference is out of
limits, replace the
Control/Display
Board.
