Caution Regarding Service

This product was precisely assembled under strict manufacturing process control. There are several hazardous locations inside of this product. Careless work while the cover is removed can result in pinching fingers or cause electrical shock. Please perform the work with the following important points in mind:

1. Setup, Repair and Maintenance

In order to ensure safety, the best performance, setup, repair and maintenance work can only be performed by the technicians received the service training specified by Canon Inc. If there are order required certificates or restrictions specified by the law or ordinances, those regulations of the country must be observed.

2. Removing the external cover

When removing the cover during maintenance, repair, etc., perform the work after switching the power off. Never touch the device with wet hands, as there is a risk of electric shock.

3. Fuse

When replacing the fuse, first, resolve the reason of failure and then replace the fuse with the specified type. Never use a fuse other than the specified type.

4. Connecting the grounding wire

The provided ground wire must be connected to the ground terminal indoors. make sure that the device is properly grounded.

5. Alternation prohibition

Never modify the medical device in any way.

6. Waste control

The service provider is responsible for the disposal of used service parts, packing material, etc. resulting from the setup, repair or maintenance of the medical device However, the customer is responsible for the disposal of the medical device. Disposal activities must follow the regulations (=specially controlled industrial waste) of the country where the device is used.

Caution regarding the setup

According to the “IEC60601-1-1:2000”, devices installed in the patient environment are

restricted to “electric medical devices conforming to IEC60601-1”.

The Control PC, operation unit, and the magnetic card reader, etc. options that are parts of the

CXDI-C3S are classified under the data processing device standard (IEC60950), therefore these

items should not be installed in the patient environment. Otherwise the Control PC is only

classified in CXDI-C3S.

The patient environment described below is an example cited from the “IEC60601-1-1:2000” –

the measurements are only guidelines. However, the “IEC60601-1-1:2000” example must be

treated as the standard.

Therefore, the CXDI-C3S must be installed in a location further than the measurements below

(outside of the patient environment).

*Areas where the patient moves (not only during imaging but when entering and leaving

the room, etc.) are also considered as part of the patient environment, therefore the installation location should be determined upon consultation with the user regarding areas outside of the patient environment.

Example of patient environment

Note: The measurements are only guidelines.

11 CCaauuttiioonn dduurriinngg tthhee iinnssttaallllaattiioonn

Please pay attention to the followings when installing the system.

(1) If the equipment is hoisted, lowered or transport, it must be supported at both sides by a

minimum of two people so there is no danger of it falling.

(2) If a forklift, etc. is used to transport the equipment, make sure there is nothing that could

impede the forklift on its route to the final destination.

(3) When installing the equipment, be sure the site meets the following criteria:

1) There must be no dripping water in the area.

2) The environment must be free of harmful elements such as humid or acidic air, air with a

saline or sulfur content, where there is poor ventilation or where air pressure or temperature is unusual.

3) The equipment must not be placed at an angle or subjected to vibration or shock (this

includes during transportation).

4) The equipment must not be kept where chemical products are stored or where gasses are

generated.

5) The site’s power supply must be of the correct voltage and frequency for the equipment.

6) The site must be connected to a fully earthed cable with sufficient ground resistance to

meet standard values.

(4) After installation, be sure to dispose of waste product packaging with care and with full

respect for the environment.

Remove the 5 screws from the back of the power box and the 2 screws on each side at the bottom of the power box.

Also remove screws on the

(2) Check the jumper pin settings on the PCB-50XRAY board in the power box. The power

supplies for 7m and 3m are not compatible due to having different output voltages. This short pin is for determining the power, not for changing the voltage.

50G power unit setting 50G Power（7m）: Short between JP1 6-8p 50G power（3m）: Short between JP1 7-8p This setting is done when shipping

With changing the jumper pin settings, the signal sent to PLD (IC1) of the PCB-50XRAY board has either state High or Low. By using this state, the PBIF50XRAY PLD code which written in the PLD can distinguish whether the power supply is for 3m or 7m.

When the echo signal for checking the cable connection and determining if the power box is 3m or 7m is sent from PCB-50Di board on the Imaging unit, the PBIF50XRAY PLD code echoes back with a noninverted if the signal is for 3m and an inverted signal if the signal is for 7m.

The Imaging unit determines the cable length based on the dip switch setting (SW1-7: OFF) on the PCB-50Di board. If cable connector P4 #1-#2 is open, cable length is 7m. If #1-#2 is connected, cable length is 3m. Based on the signal echoed back from the PCB50XRAY board and the dip switch setting, the imaging unit checks if the communication system is working properly, while also checking if the power box information (3m/7m) and cable length information are consistent.

5.2 Starting up and shutting down the System

Perform the following sequences when starting up and shutting down the system.

5.2.1 Sequence for Starting up the System

Perform the following sequence when turning the system power on.

If you do not perform the correct sequence, the imaging unit cannot be recognized, resulting in an error. (This is because the system communicates with the imaging unit when turning the system on.)

The power box cannot be turned on in conjunction with turning on the control PC.

Since the power box is equipped with a remote switch that turns on/off the secondary output, you can install the switch on your side to turn it on/off.

1) Turn on the main power of the 50G power box.

2) Turn on the remote switch of the 50G power box.

3) Turn on the control PC.

Note:

Ccrstart.bat should be registered in Windows Startup.

5.2.2 Sequence for Turning the Power off (Shutdown)

1) From OPU, select SYSTEM → [SHUTDOWN] or [SHUTDOWN after transfer]

The control PC automatically turns off.

2) Turn off the remote switch of the power box.

3) Turn off the main power of the power box.

Note:

Turn off the main power of the power box and OPU power when not using the system for

a long period.
