Diagnostics
Introduction
This section describes the diagnostic test procedures for the Live Controller
When you turn the power on, all lamps incorporated in keys light in turn. This
does not mean that the instrument performs a self–test at power on. The
performance of the Live Controller. will only be checked when you execute a
diagnostic routine.
CAUTION. These diagnostic routines includes a test which lights all key LEDs on
the Live Controller. Prolonged lighting of all the key LEDs may heat the surface
of the Live Controller enough to cause personal injury. To avoid personal injury,
you should avoid lighting all the LEDs for more than ten minutes at a time. After
ten minutes of continuous operation, you should turn all the LEDs off for at least
five minutes before turning them on again.
The diagnostic routine includes the following tests:
H Internal memory test
H RS-422 test
H Keys and LEDs test
H LCD test
H Lever and knob operation test
H Serial EEPROM test
If you find errors or if there is an indication of a problem with your Live
Controller during the diagnostic tests, refer to Troubleshooting, described on
page 9–33, for fault isolation.
Failure in some modules of the Live Controller may cause the test routine to not
operate properly. In this case, consult Troubleshooting, described on page 9–33,
to find and replace defective modules.
