siemens mobilett plus e problem

Dear Safwan,
I have all manuals for this system ,
if you need it contact me,

Error 6 meaning:-
During preparation or exposure
The rotating anode
frequency cannot be maintained above 142 Hz.
*At preparation: The anode is accelerated
for 2 s, the speed is measured.
If the rotation is too slow, the acceleration
phase is repeated and retested.
If the rotation is still too slow or the
anode looses speed too fast, a message
will be displayed.
Remove K64 page 140** during the
next test.

• Activate the radiation release
switch to the first level
(preparation) and listen for the
anode to start up; refer to page
150**.
• Check that the following supply
voltages are present on D4,
+100 V, +15 V, +5 V DC, refer to
page 150**.

• Check that the trigger pulses are
present at "ROT"; when the anode
is accelerated, refer to page 150**.
• Check that the measuring signals
"ROT_VAL" on D4 and "ROT" on
D1 are OK, refer to page 150**.

• Turn off the unit and remove K61.
Measure the stator winding in the
power plug.
➪ K61: 3-12 = 8
➪ K61: 1-2 = 5
