1.5. Safety information
The general legal and factory safety recommendations for this X-ray equipment and the following
recommendations must be strictly observed!
Start of installation, operation and maintenance work and especially electrical work must only be executed by
trained and authorized persons. This equipment must only be serviced by properly educated service specialists
who have received general and system-specific training as performed by Philips Medical Systems.
Warning!
The system/component must be switched OFF during replacement work.
Any X-ray unit produces ionizing radiation which may be harmful if not properly
controlled. Therefore, it is recommended that this equipment be operated in accordance
with the guidelines set down by the national council on radiation protection.
1.6. Service reliability information
Permanently interested in quality improvement of the PMS products, we depend on getting information from the
field.
Therefore, please send us the current generator logfile information.
Please download the generator errorlog logfile.
The filename must contain the generator serial number and generator release.
e.g. ”33960234.tdl” for rel. 3.3 and serial number 960234.

2. Stator inductance test
This test is suitable to detect internal stator coil short-circuits.
Depending on the location of a possible short-circuit (number of shorted wires), the resistance of the coil still
shows a value within tolerance but the inductivity is out of tolerance. This leads to an increased stator current
and can destroy the rotor control unit.
SRO stator (mH)
stator link wire -10% +10%
U - V 101/103 –
107/109
= 1 – 2 ≈51.7 57 62.7
V - W 208/210 –
202/204
= 2 – 3 ≈30.6 34 37.4
- Stator links not removed.
- Stator wires U-V-W disconnected.
This check can be performed with a low-cost inductance
measuring device obtainable locally or can be ordered at the
SLI Hamburg with the 12NC 4512 101 77141.
Please send the measuring results referring to the tube type and serial number together with generator serial
number and customer/site data to:
Dietmar Morgenstern Service Innovation XRT
mailto:dietmar.morg[email protected]
e.g.
XYZ hospital, Town, Country
SRO 25 50 serial number 89123 – 654123
Generator Optimus 50 970023
Inductance:
U--V = 56; V--W = 35
Appreciate your help and many thanks in advance.

3. Preparatory work
Due to the change of the cooling airflow for the rotor control unit in different generator types it is necessary to
check in which type of generator the unit is to be replaced.
In case of :
OPTIMUS RAD/RF rel. ≥3.x generator serial number ≥970218
or
OPTIMUS C generator serial number ≥986001
no preparatory work is required.
Follow immediately the replacement procedure
4.1 Replacement procedure for OPTIMUS RAD/RF rel.3.x OPTIMUS C on page 8.
If the generator serial number is ≤970217 the fan in the rotor control unit must be turned over to correct the
cooling airflow direction before the unit is replaced.
3.1. Fan airflow direction correction
• Open the cover.
Turn the screws 1..2 turns counter
clockwise to loosen the screws and remove
the cover plate.
• Remove the two ground connection screws.

• Remove the four fixing screws for
the side panel.
• Turn the unit top side down and
remove the four screws.
Turn the unit carefully back and
remove the I_I shaped side panel.
• Remove the four fixing screws of the fan and turn the fan through 180° to change the airflow direction.
Initial delivery, airflow direction for
Optimus rel. 3 and Optimus C generators.
Turned fan, airflow direction for

4. Replacements
4.1. Replacement procedure for OPTIMUS RAD/RF rel.3.x / OPTIMUS C
Caution
Switch the generator OFF and disconnect it completely from mains with the earth-leakage breaker or mains
switch!
4.1.1. Removal of old rotor control (RoCo) unit
• Remove the data cable from back panel EZX 51 and leave it with the old RoCo unit.
• Disconnect the stator wires from terminal EX 1100 (single-tube generator).
In case tube switch unit EWG is present:
• Remove plug EY 100 X3, it will be used again later.
• Disconnect stator cable Y100 – EWG at EWG K11:1 :2 :3 and leave it with the old RoCo unit.
• Remove the mains wires from ENF3: T1 :T2 :T3 and ENX 1102 and leave them with the old RoCo unit.
• Remove the RoCo unit completely from the generator.
4.1.2. Installation of the new RoCo unit
• Install the new unit in the generator.
• Connect the mains wires at ENF3: T1 :T2 :T3 and ground wire to ENX 1102.
In case tube switch unit EWG is present:
• Connect the stator cable of the RoCo unit at EWG K11: 1 :2 :3.
• Reconnect plug EY 100 X3.
Single tube generator:
• Connect the stator cable to terminal EX 1100 (U-V-W) and the cable of the RoCo unit likewise.
• Make sure the screen of the stator cable is properly connected to ground.
• Relieve the tension on the stator cable with a tie-wrap.
Note
Use screened cables. Connect the screen to earth at both
ends. (0722 215 02054)
Do not mix up the phases, otherwise components of the
rotor control may be destroyed.
• Connect the data cable at EZX51.
• Tighten all cables and wires with tie-wraps.
• Switch the generator ON.
Errors 10TD and 10TI appear because the tube data have to be updated for the new RoCo unit HS.
Copy from the service disk (4512 116 02503) file ”Tube_r3.tdl” into the release 3.x directory on
harddisk. Overwrite the old directory.
– old file same name, 173271 byte and date is 27.07.98 etc.
– new file, 182741 byte and date is 06.02.03.
• Connect the service PC to the generator and start AGenT.
Load tube data for specific tube(s).
• Select RGDV without sync contact for tube adaptation.
Systems with Bucky controller firmware rel 5.x (bDTH2, EasyD with bucky) and THORAVISION
systems:
Remove EZx42/43/23 from the back panel, wait 2 minutes to have access to the generator, set
mounted radiographical controller to none, no sync contact.
Perform tube adaptation for all tubes.

• Check that the start-up and brake function of the tube(s) work properly.
In case rotation prolongation is programmed: Once started with PREP, the anode keeps rotating for 30
seconds. After the last let go of the PREP position as long as no exposure has been switched. The
anode finally stops if an exposure has been switched or after 30 seconds or if any of the desk buttons
has been activated.
4.1.3. Documentation changes
• Exchange drawings Z1-13.2 and 5Z-2 in the service manual OPTIMUS RAD/RF.
• File the service disk in the generator book “Service Manual”
4.1.4. Return procedure
Due to the fact that no upgrade (or repair) of a new unit is possible, this kit is not declared as ”EU”
(exchangeable unit).
The old RoCol unit and cables are to be disposed of in a safe way in accordance with local safety and
environmental regulations.
