1 General Information About the Drager Service Mode SW 2.xx
You can operate the DragerService Mode with the Info key and the Reset key. These keys
allow you to change the set values, to scroll through tests, or to confirm execution of a
specific test. The DragerService Mode is subdivided into the Customer Service Mode (CSM)
and the Extended Service Mode (ESM). The working language used throughout the
DragerService Mode is English.
The DragerService Mode in Oxylog 2000 has 17 tests:
• The first five tests (Test 001 through Test 005) are specifically designed for the
customer (CSM), but can also be used by Drager service technicians.
• The other twelve tests (Test 011 through Test 022) are part of the Extended Service
Mode (ESM) which is used to carry out calibrations. These tests are only accessible to
Drager service technicians. To do so, the Drager service technician must enter a
numeric code.
1.1 Definition of the Original Status
Each function in the DragerService Mode can be carried out separately. At the beginning of
the DragerService Mode and after completion of a specific test, the Oxylog 2000 enters one
of the following original status.

1.2 Calibration Functions
The following table lists the four calibration functions available in the DragerService Mode.
The data is stored in the EEPROM:
Table 2: Calibration Functions in the DragerService Mode
No.
Function
Mode
Test No.
1 adjusting the language CSM/ESM 001
2 calibrating the pressure sensors (P-Vers, P-
AIRMIX, P_LA)
ESM 011
3 calibrating the minute volume valve ESM 012, 013
4 calibrating the autozero offset ESM 017
Caution:
After installing a new Control PCB, carefully follow the steps for calibrating (nos. 1 through
4) specified in the table above.
After installing a new Sensor PCB, perform Test Oil “Calibrating the Pressure Sensors P-
Supply and P-LA".
1.3 Reaction in the Event of a Technical Error (TE)
If Oxylog 2000 detects a technical error, it will show the error number on the display. The
technical error and the name of the current test are displayed alternately at 2-second
intervals. In the event of a technical error, all tests can be carried out normally. The message
on the display disappears as soon as the technical error has been corrected.
A new Control PCB will generate the error No. 16 (invalid check sum in the EEPROM) before
initial calibration. This technical error will disappear as soon as all data has been calibrated.

1.4 Error Messages During a Specific Test
If the system detects and displays an error, you must confirm this error by pressing the Info
key and the Reset key simultaneously. Once the error has been removed, specific tests can
be selected and carried out again.
All potential errors and their causes are listed below:
1.4.1 Power Supply Low
Problem:
battery empty
No external power supply connected. The internal
power supply is no longer sufficient for safe
operation.
1.4.2 P ressure Low
Problem:
pressure low
Gas supply pressure is too low.
1.4.3 P ressure High
Problem:
pressure high
A gas supply source is connected although no
pressure is required for this test.
1.4.4 M o de Switch Position (AirMix/NoAirMix)
Problem:
NoAirMix !
The mode switch is not in the correct position.
or
Problem:
AirMix
The mode switch is not in the correct position.

1.4.5 Mode Switch Position (IPPV, SIPPV/SIMV, CPAP)
(for Software Versions 3.xx and higher)
Problem:
pos. SIMV/CPAP
The mode switch is not in the correct position.
1.4.6 Software Version 3.xx is Incompatible with Hardware
Problem:
Hardware is incompatible.
Software Version 3.xx is not compatible with the
hardware being used.
