4-2 Troubleshooting
Addressing instrument errors
When incidental fault conditions occur, the instrument generates an error
message. Most faults require system initialization or reset. To reset the
system, use the Control menu of the 2707 Console.
Running diagnostic tests
On startup, the instrument automatically runs a series of initialization steps.
If an error has occurred, the indicator LED on the front of the instrument and
messages at the workstation show the results of these steps.
To initiate the mechanism homing steps that occur upon startup, use the
Control menu of the 2707 Console.
Displaying the statuses of signal connections
By displaying the statuses of the I/O signal connections or contact closures on
the instrument’s rear panel, the 2707 Console shows the instrument’s signal
connections in real time.
Tip:
A green LED symbol indicates that a signal cable is activating to
the terminal. A red LED symbol indicates that no signal cable is being
input to the terminal.
To display rear-panel interface connections, from the Troubleshoot menu in
the 2707 Console click Rear Panel.
Warning:
Ensure the instrument is connected to a grounded power
source.
