Diagnosis
5 Diagnosis
5.1 Maintenance
The instrument is maintenance-free.
5.2 Status indication
The mode of the CPU and peripheral cards is
indicated via the green and red LED in the
front facia. We distinguish between:
- standard operation
- communication problems.
Standard operation
In standard operating condition only the
green LED in the front facia lights on all mod-
ule cards. The red/yellow LEDs on the AR
and AT-card only signal the switching condi-
tion of the outputs.
Communication problems
Brief communication problems (up to 1␣ sec.)
on the LOGBUS do not effect the status indi-
cation.
Hardware failure
Permanent lighting of the red LED means a
hardware failure.
5.3 Failure removal
In order to detect the cause of the failure,
please use the adjustment software VVO
which gives you detailed information on the
instrument condition in the menu point “Diag-
nosis“. Using this, you can take appropriate
measures.
The diagnosis information is cyclically up-
dated in a 5␣ sec-pattern.
5.4 Repair
For safety and guarantee reasons, repair of
the instrument must only be carried out by
VEGA-staff.
In case of defects, please return the appro-
priate instrument with a short description of
the fault to our repair department.
