P05 - "Automatic" Maintenance test

Only valid if the FW version is lower than 1.5 or 1.5E.
This test is a summary of tests made in test program P01 to P04.
These tests will, once started, run automatically. Observe the display during the test. If
errors are detected during the tests, P05 is interrupted, a message will be displayed and
an audible beep will be heard. The following describes the test sequence:

P06 - Capacitor formation

(Wiring diagram X037E, page 130)
This program is used only if the unit has not been operated for several months or if sev-
eral capacitors have been replaced. The capacitors are slowly charged up to 353 V in a
controlled sequence. The test program starts by displaying:
kV
CAP For = Capacitor formation program
After a short time, the program displays the actual voltage in the capacitor bank:
kV
CAP 150 = 150 Volt.
Approximately every six minutes, the voltage value is increases. The charging sequence
increases as follows:
Siemens-Elema AB
Solna, Sweden
(P04) Display test. Visually check that the display and the LED's lights and lis-
ten for the buzzer to sound.
(P01) Filament test. If the test ends successfully, a message will be displayed
for 4 seconds:
FIL PASS = The filament part of the test is passed.
(P02) Rotation test. During the test, the actual rotation frequency is displayed.
If the test ends successfully, a message will be displayed for 4 seconds:
red PASS = The rotation part of the test is passed.
(P03) Capacitor bank and charging test. During the test, the actual voltage in
the capacitor bank is displayed. If the test ends successfully, a message
will be displayed for 4 seconds:
CAP PASS = The capacitor part of the test is passed.
If the tests B-D end successfully, the program will be ended and the display will
show:
P05 PASS = The automatic section (A not included) of the tests is OK.
If there was an error during the test, P05 is stopped and the display will show:
P05 Error xx = The test result is "not valid" . See individual test programs.
