• Reset the fluoroscopy timer to zero.
(See Start-up Instructions, paragraph 4-6)
SI Function switch of the generator
• Check functioning of the service switch on board D100 in the generator. When the ser-
vice switch is off, radiation release must be blocked (no activation of the inverter!)
• Check functioning of switch S2 on board D160. When S2 is in the OFF position, the line
contactor of the generator may not switch on. (Multiline, not operating)
NOTE
SI Protective conductor check
When the generator is switched off, there is still line voltage
present at the T1 transformer and the D160 switch-on circuit.
(See LX circuit diagram X2169-11 or SX circuit diagram X2206-11)
After switching off the generator, approx. 600 V DC is still available
for the inverter! This is indicated by LEDs V135 and V136 on board
D110.
(See LX circuit diagram X2169-16 or SX circuit diagram X2206-16)
The voltage dissipates within approx. 1.5 minutes to 0 V; the LEDs
go off at approx. 30 V.
• Test the protective conductor with the protective conductor tester according to
ARTD-002.731.17.
The protective conductor connection in the generator is the central protective
conductor.
(The protective conductor check must be performed again as a final step when the
system is closed!)

4.3 Respiratory belt
PMF Wear and tear
• Check the respiratory belt for damage/wear and tightness and replace it in the event of
damage.
(See the spare parts list).
PMP Contacts at the PS contactor (generator)
Due to the low impedance of the intermediate circuit, the power-on sequence occurs in
two steps. In the first step, the intermediate circuit capacitors are charged via the LS contactor. After the charging time, the switch-on damping circuit is bypassed with the PS contactor.
Given errors in the charging process or when disconnecting the PS contactor contacts
under load (fuses, FI switch, etc.), these can be overloaded.
• Switch off the system contactor.
NOTE
Wait until the red LEDs on D110 are no longer lit (approx. 1 min.).
• Disconnect the RC element from the PS contactor.
• Remove the spark quenching chamber from the PS contactor (remove 2 screws).
- In the case of an older POLYDOROS LX (< series no. 1020), the contactor must be
taken out in order to remove the spark quenching chamber.
The following is required for conversion:
- Cable deflector 31 57 141
- Holder for cable deflector 31 57 364
• Check the contacts for excessive melting loss.
• Reattach the spark quenching chamber.
• Reattach the RC element.

7.4 Generator
PMA Checking/setting the tube filament heating
Not necessary if the check according to the start-up instructions is within the tolerance!
X Observe radiation protection regulations!
In the case of POLYDOROS, the filament heating functions as a constant current regulator.
Filament vaporization increases the resistance. Given a constant filament current, the filament power and the filament temperature also increase. If the filament current is not corrected, filament vaporization accelerates.
An increase in filament temperature of approx. 2-3% reduces the service life of the tube
by half.
Keep prep. time (preparation) short!
Always push the exposure release button down fully.
Let go of the release button immediately following the exposure.

POLYDOROS LX:

- CH 1 = D100.X18 (kV actual)
- CH 2 = D100.X61 (mA actual)
- Trig.ext. ( - ) = D100.X48 (SWR )
- CH 1 = D100.X61 (kV_ACT)
- CH 2 = D100.X64 (MA_ACT)
- Trig.ext. ( - ) = D100.X64 (SWR )
• Set the following for each focus: - 73 kV
-100 %
- Change the mAs value until an exposure time of approx. 100 ms is
displayed.
• Release an exposure.
• Evaluate the oscillogram.
- The high voltage should be ± 5 % of the set value within 10 ms.
- The tube current should be ± 5 % of the set value within 50 ms.
- It is favorable for the service life of the tube for the tube current to be below the set
value (max. 20%) during power-on.
- An initial brief spiked overshoot (e-function < 3 ms, depending on the length of the HV
cable) is the charging current of the HV capacitors and can be ignored (does not flow
over the tube and therefore does not affect dose).
