Table 6.7 System Errors
Error Explanation Action
Current monitor
(Power supply high
amps)
Input line current is too large.
Hardware detects that the
Instrument is drawing too much
current from the wall. The total of
all amplifier outputs exceeds system
specifications.
Reduce the source amplitude or
reduce the load.
Voltage monitor
(Power supply high
volts)
Either the AC input line voltage is
too high, or power is being fed back
into the F6000 through the
amplifier outputs.
Reduce the input line voltage.
Open ground
detector
(Power supply)
Hardware detects an open ground
detector.
This hardware problem must be
addressed before it is safe to
operate the F6000.
When the F6000 clears the error, it
occurs again if the hardware
problem has not been fixed.
Logic Output
(Logic I/O)
Hardware detects an overcurrent
condition on a logic output. The
F6000 software shuts down all
amplifiers. The F6000 hardware
latches all logic outputs open.
Reboot the system. If the error
persists, replace the Logic I/O
circuit board (see ”Circuit Board
Replacement” on page 7-17).
+12 Volt fail
monitor
(DC power supply)
Hardware disables amplifiers to
prevent damage to relays on the
amplifier assemblies if System
+12 V falls below a threshold of
approximately +5 volts.
Check the DC power supply.
