Hardware Errors
The following is a list of fatal hardware errors. LogBook’s ERROR LED indicator (on the front panel)
will blink on/off the number of times indicated by the flash code. If the LogBook is attached to an LBK1,
the corresponding control terminal message will be displayed (otherwise, you must count the LED flashes
to determine the error). Note that flash codes 08, 09, and 17 are associated with multiple errors and thus
require an LBK1 to determine which error applies.
