PRELIMINARY INFORMATION

This unit has been assembled and checked in factory following methods certified both for production and testing. The same methods are in compliance with the most recent international Standards and with the European Directive for Medical Devices (93/42 CEE).

During checking phase it is draught a Test Report including the following information is draught:

• Output data accuracy (kV-mA-time) test

• Light field  X-ray field conformity test

• Electrical safety (PE resistance and leaked currents)

To ensure the unit safety and efficiency even during the transport between firm and user, some tests and functional checks are required. It is necessary to perform those tests upon installation.

To check the output data, therefore kV and X-ray time measurements, the use of non-invasive tools is required. Should tools be not available, check these values on the unit display directly (see next pages).

Perform what described in this chapter, even if additional and specific acceptance tests are required

(i.e. by hospital or Government).

6. Mains cable

7. X-ray button and button cable

8. Generator-monobloc-collimator connecting cable

PRELIMINARY KNOWLEDGES

Before proceeding with the unit installation the technician has to carefully read the chapter “Service information”

. It includes several useful information to perform the installation properly.

MECHANICAL TESTS

Move the unit from the parking condition (unlock the arm) by pulling and rotating (90°.) the release

pawl.

Check the monobloc group balancing and rotation towards the longitudinal axis.

Unlock the monobloc brake and check the monobloc group rotation (±180°) around the horizontal

axis. Furthermore check the right gonimeter indication. Check the proper collimator rotation around his vertical axis (±135°).

Check the stationary brake and the directional handle.

Place the handle in the following positions (refer to the label attached on the arm column) and check the proper functioning:

• pos. 1: brake ON

• pos. 2: oblique left-right motion

• pos. 3: backward-forward motion

• pos. 4: oblique right-left motion

• pos. 5: left-right motion

UNIT SUPPLY

Preliminary operations

The Practix 100 plus automatically adapts to the mains. The unit performances do not depend on mains voltage (115V or 230V). Only the anode starting time and, as a consequence, the preparation time, depend on the mains voltage (0,8s @230Vac - 1,6s @115Vac). These parameters are automatically set by the unit.

Before connecting the unit to the mains check the following:

1. mains voltage..........................................115V or 230V (±10%) monophase

2. mains frequency......................................50Hz or 60Hz

3. available power.......................................3kW (16A max)

4. mains plug with earth connection

Before connecting the mains make sure that the PLUG IS GROUNDED.

Mains connection

Then it’s possible to connect the unit to the mains.

The mains voltage presence is indicated by the turning ON of the yellow led placed aside the ON button. Should the led be OFF, make sure that the automatic switch is turned ON.

PRACTIX 100 plus Installation & Acceptance

ELECTRICAL TESTS (NO IRRADIATION)

Never perform an exposure in this phase. It may be dangerous for the unit integrity.

Ignition - Start up - Ready

1. Turn the unit ON (press the ON button) and follow step by step the Start up sequence, checking its proper performing (refer to chapter “Service information”).

2. If no problem is detected the display will show the message “READY” after the Start up phase.

Collimator check

1. Completely open the collimator blades.

2. Press the COLLIMATOR button located on the keyboard (or on teh same collimator), turn the collimator lamp on and check its proper functioning (approx 30s long).

Data setting and preparation check

1. Verify the functioning of the kV and mAs increase/decrease buttons.

2. Perform X-ray preparation (just press the first step of the button for 3s at least) and check the proper anode rotation.

3. Upon the button release, check the anode proper braking.

TUBE PREPARATION

Warning: X-ray presence, use proper protections.

PRACTIX 100 plus Installation & Acceptance

Arrange the tube for X-ray performing the Warm-up ( procedure (kV step-up). Perform these procedures with the TUBE SEASONING program (refer to SERVICE MODE, chapt. “Service information”). At Start up, after a long inactivity period (3 months or more) the display will show “TUBE SEASONING” message. Therefore, it’s necessary to proceed with the TUBE SEASONING program (refer to SERVICE MODE, chapt. “Service information”).

After the seasoning DO NOT perform any exposure. Let the monobloc cool down for 8 minutes at least.

ACCURACY TEST

Output data check

Warning: X-ray presence, use proper protections.

Place in the X-ray field a non-invasive tool for the kV and X-ray time measurements according to what indicated in the tool manual.

Perform the exposures listed in this table and verify that the measured values are in the allowed limits.

Set data output

X-ray irradiation field check

Warning: X-ray presence, use proper protections.

This test verifies the correspondence between collimator light and X-ray field.

Place under the collimator, at 1m from the focus, a 18x24 cassette with film.

Press the COLLIMATOR button (both on collimator and keyboard); the lamp will be ON for approx.

30s. Rotate the handles placed on the collimator and adjust the shutters opening, in order to light the

whole surface of the cassette. Perform an exposure (i.e. 63kV/10mAs) and check the proper irradiaton of the film (at least within

the requested tolerance).

The X-ray data/parameters vary in function of the cassette type. As alternative to the cassette it’s possible to use a fluorescent, graduated, high persistence screen (field position analyzer).
