1.1 About planned maintenance

These instructions include procedures for a planned maintenance (PM) for Datex-Ohmeda S/5
Anesthesia Monitor and S/5 Critical Care Monitor. The Planned maintenance should be performed
once a year.

Planned maintenance instructions

These instructions include a Check Form
corresponding procedures.

The symbol
check form.

The procedures should be performed in ascending order, bypassing those that are not applicable
for a particular monitor.

If you need further information how to perform a certain PM procedure, please refer to the
corresponding slot in the Product Service Guide in the Technical Reference Manual.

All menu selections related to
e.g.
As you enter the service menus, you need following passwords:

Monitor Setup

In case you evaluate the measurement accuracy with a patient simulator, add simulator’s accuracy
specification to the one of the monitor.

The procedures are designed for monitors with S/5 monitor software L-ANE01(A) or L-ICU01(A).
However, most of the procedures also apply to monitors with older monitor software.

2 PLANNED MAINTENANCE CHECKLIST

2.1 Visual inspection/preparation

2.1.1 General

NOTE: Wear a static control wrist strap when handling PC boards. Electrostatic discharge may
damage components on the board.

• Make sure that the monitor is switched to standby.

Disconnect the mains power cord from the 8-Module Frame, F-CU8. If the monitor is
connected to the Datex-Ohmeda network, disconnect the Mon-Net cable from the Network
Board, B-NET or UPI4NET board, B-UPI4NET. If the Memory Module, M-MEM is connected,
remove any memory cards.

1. Check all units visually. Check e.g. that all parts are intact, the cables and screws are
connected and tightened properly.

Especially check the following parts:
Video displays : the display power cord is locked to the display.

F-CU8: the equipotential tap and all the screws are tightened properly.
Airway Module, G-XXXXX: the equipotential tap is tightened properly.

Check that modules go in smoothly and lock up properly in all module slots.

2. The lead-acid battery in the power supply unit is recommend to be replaced after every 4
years. Replace the battery, if necessary.

The SRAM/Timekeeper battery on the CPU board is recommend to be replaced after every 8
years. Replace the battery, if necessary.

NOTE: The Factory Reset should be performed if the SRAM/Timekeeper battery, or the
SRAM/Timekeeper chip is replaced.

3. Clean or replace the F-CU8 fan filter.

4. Check that the fuses are of the correct rating.

?

2.1.2 Extension Frame, F-EXT4

1. If the F-EXT4 contains a fan, clean or replace the fan filter.

?

2.1.3 Airway Module, G-XXXXX

1. Remove the Airway Module case, the top protection cover and the bronze plate from the

side of the O2 sensor, if installed.
Detach the PVX board with the support plate, if installed, and leave the board detached

until further notice.
Check that all cables and tubes are connected properly and there are no loose objects

inside the module.
NOTE: Make sure that none of the tubes are in contact with the sampling pump or with the

O2 sensor.

2. Install the PM Kit
Replace the special tubes (Nafion™).

Replace or install the OM ref. filter, order code 86901.
Check the D-fend O-rings and replace them, if necessary
Replace the D-fend and the sampling lin e.
Clean or replace the fan filter.

NOTE: Use only Datex-Ohmeda sampling lines to ensure proper functioning.

3. The CO

necessary.

absorber is recommend to be replaced after every 4 years. Replace the absorber, if

2.1.4 Compact Airway Module, M-CXXXXX

1. Detach the module box.
Check that all cables and tubes are connected properly and there are no loose objects

inside the module.
NOTE: The tubes connected to the Oxygen board pressure transducers should not be

pressed too deep.
NOTE: Make sure that tubes are not in contact with the sampling pump or the O

its springs.

2. Install the PM Kit:
Replace the special tubes (Nafion™).

Replace the Ref. filter assembly.
Replace the filters in the pneum atic unit (2 pcs).
Check the D-fend O-rings and replace them, if necessary.
Replace the D-fend and sampling line.
Clean or replace the fan filter.

NOTE: Use only Datex-Ohmeda sampling lines to ensure proper functioning.
Use a 2 m/7 ft sampling line with Compact Airway Modules M-COVX and M-CAiOVX.

3. The CO
necessary.

Note: All Compact Airway Modules do not contain a CO
