NOTICE
The following instructions must be observed!
¹ When performing the work steps and tests, comply with
the following:
¹ - The product-specific safety information in the docu-
mentation, safety information TD00-000.860.01.03.01,
¹ - As well as the general safety information contained in
ARTD, part 2.
¹ Pull the power plug before starting to work on the ARCA-
DIS Orbic.
¹ Ensure compliance with the general safety requirements
when working with the system connected to the mains.
¹ Observe ESD guidelines!
¹ Before beginning maintenance, perform the ground wire
test according TD00-000.860.01.... The ground wire resis-
tance must not exceed 0.2 Ohms.
¹ Switch off the ARCADIS Orbic before replacing modules
or boards.
¹ Perform the ground wire test according to
TD00-000.860.01... upon completion of the work and after
all covers have been reattached. Take down and evaluate
the determined values. The ground wire resistance must
not exceed 0.2 Ohms.
¹ After all work has been completed and all cover panels
have been installed, perform the ground wire measurement according to ARTD-002.731.17.
¹ The ground wire resistance must not exceed 0.2 Ohms.
¹ When performing service work on the power-on module,
(replacing the power-on module or replacing the power
cable), the equivalent leakage current must be measured
and recorded.
¹ Checks and settings that need to be performed under
X-ray radiation are identified by the radiation warning
symbol x . While performing adjustments labeled in
this manner, radiation protective clothing must be worn.

1.9 Technical Safety Checks (TSC)
Abbreviation: TSC = Technical Safety Checks
NOTE
Technical safety checks,
Test protocol check
Within the purview of DIN VDE 0751-1, the operator of medical engineering products has to perform technical safety checks at regular intervals.
The checks listed in these maintenance instructions contain all
technical safety checks according to DIN VDE 0751-1 except for
the check of the completeness, presence and legibility of the necessary operator documents.
A separate protocol with the print number SP00.000.834.01... is
available for each technical safety check.
Within the purview of DIN VDE 0751-1, we recommend documenting the maintenance results both in the maintenance protocol and
in the TSC protocol. The protocols should be filled out completely
and handed over to the client after maintenance is completed.
In the table below each technical safety check listed in the document SP00.000.834.01... is assigned to the corresponding maintenance work.

The acoustic warning signal must sound every 4, 5.5, or 9.5 minutes of the fluoroscopic time depending on the programming. It
sounds again every 5 or 10 minutes. It is turned off by pressing the
-0- button once. Pressing this button again resets the fluoroscopic
timer to "0". Depending on the country-specific programming, either the required radiation shut off does not occur or it occurs every 5 or 10 minutes and then every 5 or 10 minutes after that.

SIE 3D reconstruction (if present)
NOTE
The equivalent leakage current is to be measured and documented
using the equivalent leakage current tester according to
ARTD-002.731.17 in the scope of validity of DIN VDE 0751. Refer to
the section "Final work steps".
The instructions according to ARTD-002.731.17 are to be adhered
to outside the scope of validity of DIN VDE 0751.
The calibration of the 3D reconstruction is part of the safety inspection. It can, however, also be performed together with the IQ
quick test.
See chapter 5, "IQ quick test".
• Check the belt tension of the toothed belt for motor-controlled orbital movement.
• Press the emergency stop switch and perform a 3D scan.
The motor-controlled orbital movement must not start up.
• Deactivate (disengage) the emergency stop switch.
X
• Start a further 3D scan. The 3D scan must be executed properly. The motor-controlled
orbital movement must stop at the end position of the C-arm.
• Calibrate the 3D reconstruction. See "IQ quick test".
• Check the 3D limiting resolution. See "IQ quick test".
• If the system is equipped with a navigation system, the required calibration of the 3D re-
construction has to be performed together with a navigation system engineer. Before
starting calibration, make sure that the I.I. cap of the navigation system is in place. See
"IQ quick test".

SIE Voltage discharge rubber
Checking the overall accuracy of the navigation system in combination of the 3D reconstruction is part of the safety inspection. It
can, however, also be performed together with the IQ quick test.
See chapter 5, "IQ quick test".

damage or dirt. If necessary, clean or replace it.
SIE Ground wire test
• Measure the ground wire with the ground wire tester according to TD00-000.860.01... .
NOTE
The ground wire test is part of the safety inspection. However, it
cannot be performed until all maintenance work has been completed. Refer to the "Final work steps" section.
SIE Equivalent leakage current
• Perform the equivalent leakage current test, with a closed system, according to
TD00-000.860.01... . Take down and evaluate the determined values. Document the
measuring procedure.
The equivalent leakage current must not exceed 2 mA.
NOTE
The equivalent leakage current test is part of the safety inspection.
However, it is recommended to perform it only at the end of maintenance, with a closed system. Refer to the "Final work steps" section.

SIE Ground wire test
SIE Ground wire resistance
• Perform the ground wire test with the system closed (ARTD- 002.731.17.).
Document and evaluate the determined values.
The ground wire resistance must not exceed 0.2 Ohms.
NOTE
SIE Leakage current
• Measure the leakage current according to ARTD-002.731.17....
Document and evaluate the determined values.
The limit value of 2.5 mA may not be exceeded.
NOTE
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding maintenance
procedures or safety checks.
A sudden or unexpected increase in the measured values may indicate a defect in the ground wire connections (ground wire or
contacts) - even if the limit value of 0.2 Ohms is not exceeded.
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding maintenance
procedures or safety checks.
A sudden or unexpected increase in the measured values may indicate that an error occurred in the primary circuit of the power
supply (damaged insulation, damage caused by water ingress or
humidity, defective interference suppressor, etc.) - even if the limit
value of 2.5 mA is not exceeded.
