3 Service procedures
3.1 General service information
The field service of the Device Interfacing Solution is limited to replacing faulty cables or 
mechanical parts. The circuit boards should be returned to GE Healthcare for repair.
GE Healthcare is always available for service advice. Please provide the unit serial number, full 
type designation, and a detailed fault description. 
WARNING Only trained personnel with appropriate equipment should perform the 
tests and repairs outlined in this section. Unauthor ized service may void the 
warranty of the unit.
3.2 Service check
These instructions include complete procedures for a service check. The service check is 
mandatory after any service repair. However, th e service check procedures can also be used 
for determining possible failures.
The procedures should be performed in ascending order.
The instructions incl ude a check form (“APPENDIX A:”) which may be used when performing the 
procedures. 
The symbol 
in the instructions indicate s that the check form contains space to record the 
results of the particular procedure.
3.2.1 Recommended tools
3.2.2 Recommended parts
No recommended parts.
3.2.3 Visual inspection
Disconnect the DIS module from the DIS bus and from the interfaced external device.
1. Internal check
•Disassemble the DIS module.
•Make sure that there are no loose parts inside the DIS module.
•Check that the screws holding the PC board are tightened properly. 
•Check that the cables are attached properly and the connectors are intact.

Tool Order No. Notes
Screwdrivers

2. External check
•Check that the DIS module case and label are clean and intact.
•Reassemble the DIS module.
•Check that the screws for the DIS module case are secured properly.
•Check that the bus cable connector is intact.
•Check that the DIS bus and device specific cables are intact.

3.2.4 Functional inspection
3. DIS module interface statusConnect the DIS module to the DIS bus and to the external device that is specified in the 
DIS module label. Turn on the interfaced external device.
Check that no error messages are displayed on the monitor screen.
Check via the  Interfacing menu that the connected DIS module status is correct:
Monitor Setup - Interfacing - Status Page 
Check that the waveforms and numeric data are transferred to the monitor according to 
the configuration.

4. Recognition of interface Disconnect the DIS bus cable and check that the ‘[device name] module removed’ 
message appears on the monitor screen. Reconnect the cable.
Turn off the external device (if possible) and check that the ‘[device name] disconnected 
from module’ message appears on the screen. Turn the external device back on again.

5. DIS module service menuEnter the service menu:
Monitor Setup – Install/Service   (password 16-4-34)  – 
Service    (password 26-23-8)  – 
Parameters – DIS Interfacing
Check that the menu displays submenus for all connected DIS modules.
Enter the corresponding DIS module service menu and check that the displayed 
information corresponds to the info rmation on the DIS module labels.
Check that the DIS bus voltage is between 13.80...16.00 V.
Check that the DIS module time-out and checksum error values do not increase more 
than by 5 per second.
Check that the status of each DIS module memory indicates OK.

6. Electrical safety checkPerform the electrical safety test and leakage current test. 

7. Functioning after electrical safety checkCheck that the DIS module func tions normally after the tests.

8. Final cleaning
Clean the DIS module, bus cable and device  specific cable with a suitable detergent.

•Fill up all the necessary documents.

3.3 Disassembly and reassembly
3.3.1 Before disassembly
WARNINGWear a grounded, antistatic wristband when handling PC boards. 
Electrostatic discharge may damage components on the board. 
Handle all PC boards by their edges.
3.3.2 Tools needed
3.4 To disassemble the module
To disassemble the N-DISxxx module (see the ex ploded view of the module in the “S/5 FM 
Spare parts” slot):
1. Remove the two screws fr om the back of the module. 
2. Loosen the two strain-relief threads and af ter that disconnect the cables from the 
connectors.
To remove the Module Front Cover from the mo dule, release the snaps that hold the front 
cover to the front chassis.  
To reassemble the module, reverse the order of the disassembly steps.
CAUTION When reassembling the module, make  sure to reconnect all cables properly.
Always perform the “Service check” after reassembling the module.

4Troubleshooting
4.1 LED indicators
Figure 5 LED indicators
4.1.1 Green LED
The  green LED indicates that the communication between the monitor and DIS module and 
the communication between the DIS module and external device is working properly. When all 
cables are connected and the connected devices are on, the green LED should be lit 
continuously.
4.1.2 Yellow LED
The yellow LED alerts the user. The yellow LED is lit when any of the  following conditions 
becomes true:
1. The DIS module is connected to the DIS bus,  but the external device is not connected.
2. The external device is in power off state.
3. The external device is not selected from the interfacing menu as an active source of data.
NOTE: The meaning of the yellow LED varies with some external devices. See the “Installation 
Guide” delivered with the DIS module.

4.2 Quick functional check
You have two ways for checking the functi on of the Device Interfacing Solution:
•Press the Monitor Setup key, select Interfacing  and open the  Status Page menu. The 
status page shows you the current communica tion status of the interfacing modules 
connected to the bus (1...4 pcs). 
NOTE: The status message ‘Connected’ appears on the monitor screen after you have 
connected the external device to the DIS modu le and turned it on, if the monitor and DIS 
module have alread y been initialized.
•Check the LED indicators on the DIS module (the green LED indicates the physical 
connections, the yellow LED software selections):
GREEN YELLOW INDICATION
lit             dark          Physical connections between the monitor, DIS module 
and external device are in order and the device has been 
selected in the menu.
dark       lit            There is something wrong with the physical connections 
between the monitor, interf acing module and external 
device. The external device has not been selected in the 
menu.
lit              lit             Physical connections between the monitor, DIS module 
and external device are in order, but the external device 
has not been selected in the menu (see the “User’s 
Reference Manual” of the monitor).
