Possible reason
•
"Err 33" messages can be ignored.
This message can only be read out
from the message history, P08.
The message is only used as aid
for the software development.
•
Acknowledge and clear the mes-
sage history.
Messages are being lost and not dis-
played for the customer. All mes-
sages are stored in the error
memory.
•
Using section "P08 - Display of
message protocol ", display and
record the messages contained in
the error memory. Using the error
message list, try to determine
which module, board, etc. is
generating the messages.
•
Check the supply voltages on D1,
see page 110**.
•
If the message appeared once, it
may have been caused by a tube
arc that disturbed the program
execution. If the message "Err 35"
occurs repeatedly, the single tank
must be checked according to
"Error diagnosis HT and single
tank". If the function of the single
tank is OK and "Err 35" appears
several times, replace D1.
