Part 3 Using Support Functions

Part 3 Using Support Functions
There are various support functions available in the monitor to assist in fault diagnosis. These
are described below. If diagnostic and error information is to be communicated to Philips,
this should always associated with a particular instrument by means of the serial number. The
serial numbers for the Monitor and the Measurement Server can be seen in the "Revisions"
window (press Setup key then select "Revisions"). However, if a Measurement Server
Extension (M3015A or M3016A) is in use, the number will not appear and must be noted
down from the back of the Extension. To do this, remove the Measurement Server and
Extension from the Monitor, so that the back of the extension is visible.

The Status Log and Error Codes

One possible line of fault isolation is in the error codes. However, some error codes cannot
provide diagnostic information at the repair site and must be analyzed in the factory if they
appear repeatedly. Whenever one of the subsystems is unable to perform an operation, an
error code is generated. Error codes are assigned to fatal and non-fatal errors.
Error codes can be found in the Status Log while in the operating modes. In the
Configuration, Demonstration, and Monitoring modes, the Status Log only displays fatal
error codes. In the Service Mode, the Status Log displays both fatal and non-fatal error codes
with a blank line separating the two.
Errors that occur during start-up or regular monitoring are logged in the Status Log. The
Status Log can be printed and cleared. If fatal errors occur repeatedly, send a printout of the
Status Log (Service Mode) to Philips.
There are two categories of error:
Fatal Errors—These errors indicate major problems that cause the Monitor to reset and re-
start. These types of errors might force the Monitor to go back to user defaults. Fatal errors
usually point to a defective System Board. This will be reported to the user by the INOP
alarm: CHECK STATUS LOG. The fatal error can be reviewed in the Status Log menu.
After the Status Log is reviewed, the INOP is removed.
If a fatal error occurs which cannot be diagnosed, download the Status Log into a file using
the M3 Support Tool and send it to the Technical Marketing department at Philips Medical
Non-Fatal Errors—These indicate general errors that are not significant enough to affect
normal Monitor operation. Non-fatal errors are errors that give some hints about an
unexpected behavior of the system but that are not relevant to correct system function. They
do not cause the Instrument to reset or restart. They are not reported during monitoring but
can be seen in the Status Log if the Monitor is in Service Mode.
Monitor, Measurement Server and Measurement Server Extension errors are reported
separately in the Status Log.
