Mounting the x-ray tube assembly 1

The installation of the x-ray tube assembly to the unit is described in the corresponding unit installation instr uctions. Please observe especially the notes in the TI 376 (R71-020.038.03..., tube assembly flange adjusted at the factory).

During the start-up phase, voltages o f reason, use only shielded cables! The shielded braiding of the stator cable is not tube assembly side, except when the double-shielded rotatinganode cable is used, or in the case of other information specified in the generator installation instructions.

• Secure the stator to the x-ray tube assembly us ing a compression clip and clamp.

Secure the double-shielded rotati ng anode cable to the x-ray tube assembly using t he clamp but not the compression clip (Fi g.2) (braid to ground).

Stator frequency 50 Hz or 150 Hz

• Connect the stator cable to the terminal bl ock of the x-ray tube assembly (Fig . 1)

according to the provided starter (stator frequency 50/60 Hz or 150/180 Hz) .

- Observe notes on the inner side of the anode-s ide protective cover.

-With 3

~ stator s, the stator windings are not changed over.

• Observe notes in the generator instru ctions and wiring diagrams. Connect starter s N80,

N81 and N90 generally for 150 Hz.

Stator frequency 300 Hz (17000 rpm)

Only x-ray tube assemblies which are intended for a stator frequency of 300 Hz may be connected to a 300 Hz starter. For reasons of safety, the stator in the 300 Hz tube housing ”117 GL” is switched so that the high speed (17.000 rpm) is only obtained with this tube assembly.

• For this purpose, run 2 separate shielded st ator cables to the x-ray tube assembly. Se e

also the corresponding documents refe rring to the 300 Hz starter.

The connection of 150 Hz tube housings (100,102 etc.) to the 300 Hz starter results in a failure of the power safety circuit breaker in the starter!

Protective ea rthing 2

• Run ground wire ≥ 6 mm

on the high-voltage generator.

CAUTION

LOADIX connection 2

Not for three-phase stators!

Terminals 1 and 2 are connected with the LOADIX measuring cell. To secure this measuring cell, connections 1 and 2 are provided with a jumper.

• The jumper and the adaptation resistor must be removed only on connection to the

LOADIX. See LOADIX installation instruc tions.

Temperature limit value switch 2

BWhen the temperature limit value is ex ceeded, the oi l pres sure switch r esponds an d the radiation release is inibit ed in the generator if the swit ch in the generator is connected e.g. in series with the door contact. Depending on the type of generator, an error message is output.

If the ”LOADIX” is connected, the tube assembly symbol lights up and a warning signal sounds.

Fan mode

- Basically, all tube assemblies can be operated with one or two fans.

- Exception: STEREOLIX

- The installation or connection of th e fans is described in the fan instal lation instructions.

High-voltage connection 2

The tube assembly is provided with ”0” plug connectors. This implies high-voltage cables with ”0” sealing ends.

For installation of the high voltage cables, see the Instal lation Instructions, RX0-000.031.01... in the generator binder, Reg.3.

High-voltage cables with 3-pin ”0”plugs can be connected both on the anode and on the cathode side (Fig.3). With tube assemblies with final designations GL a 4-core high-voltage cable is necessary on the cathode side (Fig. 4).

If a 4-pole

→ 3-pole transition piece is used (supplied wit h part-no. 97 46 223 X1751), this

may be inserted only on the high-voltage transformer side.

In order to prevent overheating of the filaments, a check must be performed with the cathotest tube phantom before insertion of the cathode-side high-voltage cable in the x-ray tube assembly

See the generator setting instructions and the instructions ” cathode tube phantom” (TI 300 RA0-000.073.06...)

Pre-filtering of the x-ray tube assembly 2

With supply with additional filter, inherent filtering of the x-ray tube assembly is at least

2.5 mm Al equivalent. Additional filtering comprises a filter cone (0.5 mm Al) and one or two filter disks (0.5 mm Al each).

• Remove the unnecessary filter dis ks according to the attached collimat or*.

* Collimators with mirror, note on ”Al equivalent 1 mm” attached.

Startup 3

Startup of the tube assembly with high voltage 3

Referring to ”Setting the tube pre-heating”:

• Perform setting of the tube pre- heating according to the corresponding gen erator

setting instructions. Depending on the generator, the tube assembly can be warmed up before setting the tube pre-heating. Pre-heating must be performed. With generators without this funct ion, the tube assembly must be warmed up as follows after setting the pre-heating:

- Switch on fluoroscopy at lowest kV stage

- Adjust up to 110 kV, 4.1 mA within approx. 1 min

- Leave fluoroscopy switched on for 10 min Monitor kV and mA on the oscilloscope

In the case of malfunctions (ignit ion of the tube), fluoroscopy must be perfo rmed for a longer time at a reduced kV value. Only then may t he kV value be increased. If fluoroscopy is working without any mal functions, begin adjustment of the ex posure heating. If operation is not possible without any malfunctions in spite of longer fluoros copy, the tube assembly must be replaced.
