Edition 1, Revision 1 ADC Compact Plus Chapter 9 / 1

(Type 5146 / 100/200)

1 Safety

· The ADC Compact Plus has been designed for scanning medical X-ray

image plates and should only be used for these purposes.

· The ADC Compact Plus must only be operated by qualified staff trained on

the machine.

· Make sure that the ADC Compact Plus is constantly monitored in order to

avoid inappropriate handling, especially by children.

· Only trained service personnel must make repairs. Only authorized service

personnel must make changes to the ADC Compact Plus.

· If there is any visible damage to the machine casing, do not start nor use

the ADC Compact Plus.

· If you want to connect the ADC Compact Plus with other devices,

components or assemblies and if the technical data do not permit

determining whether the combination with these devices, components or

assemblies involves hazards, you must consult the respective

manufacturers to avoid danger for operating personnel or the environment.

· Do not override or disconnect the integrated safety features.

· Switch off the ADC Compact Plus before performing any maintenance

work or repairs. Disconnect the ADC Compact Plus from the mains before

making repairs or performing any maintenance activities.

· As is the case for all technical devices, the ADC Compact Plus must be

operated, cared for and serviced correctly.

· If you don't operate the ADC Compact Plus correctly or if you don't have it

serviced correctly, Agfa-Gevaert is not liable for resulting disturbances,

damages or injuries.

· When installing the ADC Compact Plus, care must be taken to ensure that

there is either a mains plug or an all-cable disconnecting device in the

internal installation fitted near the ADC Compact Plus and that it is easily

accessible.

· If you notice conspicuous noise or smoke, disconnect the ADC Compact

Plus immediately.

· Check that the mains voltage is within the specified range of the self

adapting power supply of the machine.

Maintenance

Chapter 9 / 2 ADC Compact Plus Edition 1, Revision 1

(Type 5146 / 100/200)

· You can hurt your fingers if they are caught between the ADC Cassette

and the edge of the input slot. Insert the cassette in the input buffer as

described in the User Manual. At all times, keep your fingers clear of the

input slot. As soon as the ADC Compact Plus takes in the cassette,

release it.

Warning Label at the Input buffer of the

ADC Compact Plus.

2 General Information

These maintenance instructions must be considered confidential.

To ensure quality and functional reliability of the system all the points listed

below (minimum maintenance points) must be carried out.

· The maintenance points have been arranged in a chronologically

suitable order to make the work routines as efficient as possible.

The sequence of the maintenance points in the checklist (see

appendix) is identical with these maintenance instructions.

· If there is a detailed description for a certain maintenance point in

the service documentation, this will be noted in the column "details".

· During the maintenance procedure always consider the safety

instructions, see TECHNICAL DOCUMENTATION chapter 1 / 1.

· Please check if it is necessary to include country specific regulations

as additional maintenance points!

Only for Systems with DRA Contract:

In systems with DRA Contract the infocounters are checked and evaluated in

regular intervals by the GSC. If there is an indication of an upcoming defect,

this is noted in the DRA Report and sent to the respective NSO with

instructions for measures possibly required on the machine.

Therefore we recommend to contact your NSO about this subject before

maintenance, in order to perform these recommended measures in addition

to the "must" maintenance points.

2.1 Maintenance Frequency

The maintenance has to be carried out:

· every 25.000 cycles or

· once a year

3 Maintenance Step by Step

3.1 Diagnostics

3.1.1 Questioning of the customer

· Ask the customer for any problem that appeared since the last

maintenance.

3.1.2 Infocounter Analysis

· Service PC to analyze the infocounter

(1) Insert an empty floppy in the

floppy drive of the cPCI-Rack,

see Figure 1.

(2) In the service menu select

"Save on floppy"

with the key and press

(3) Select "Infocounter file" and

press

(4) Remove the floppy from the

floppy drive and insert it in the

Service PC.

(5) Unzip the file "5146_xxxx_icn.zip"

(xxxx stands for serial number)

(6) Start an editor (e.g. notepad or

wordpad).

(7) Open the file

"\D_\infocounter\0\infocounter.txt"

(8) Evaluate the infocounter file.

3.1.3 How to evaluate the Infocounter

What to check in the

infocounter

Comment

1.1 Device Info: Serial

number and Installation

date

Compare device serial number to chapter 8

“Manufacturing Standard Modification” and

chapter 10 “Field Service Bulletins” to determine

whether the device is modified or requires a

modification.

1.4 Software Info It is recommended to have the latest software

installed. Before you upgrade to a new software,

make sure that your hardware is up to date.

2.2 Throughput For throughput most important are the cycles per

day. They usually count between 50 and 200.

Comment

3.3 Hardware

Modification History

By comparing the status of the device with the

available “Field Modifications”, chapter 7, the

exact hardware status can be determined.

3.4 Software modification

history

By checking the software modification history it

can be determined, whether a recent software

upgrade solved a problem, that occurred quite

often in the error list.

4.6 Laser Power Check that laser power is constant: no more than

1mW difference in between two entries. If the

value is higher, run diagnostic software and

scan&signals and check laser diode module.

4.7 Polygon Jitter

Monitoring

If amplitude exceeded 300 milli-pixel, check

accurately the image quality on the workstation.

Do not exchange optic modules without having

contacted the Support Center.

The entries are only indications and can

only be interpreted as one symptom which is

conducted to the optic module.

5.3 Retries Many retries (> 1%) have to be investigated:

They usually lead to less throughput of the

device. Compare it with frequent error codes.

5.7 Error History Check the last occurred errors (in between two

maintenance), how often they appeared as well

as the CBF (cycles between failures) of these

errors. This gives an overview of the current

status of the machine.

Compare the frequently occurring errors to the

error list in chapter 3.3, and take actions.

5.8 Error List Relatives

and

5.9 Error List Total

Troubleshoot these errors with the help of the

technical documentation, chapter 3.3,

“Troubleshooting”.

3.1.4 Clear Infocounter

(1) Clear the infocounters to refresh relative counters.
