Cedex Bio System

11 Troubleshooting

Introduction

Introduction

Effective troubleshooting requires a good understanding of all basic operating 
procedures for the 

Cedex Bio

 instrument and the system software. 

Preventive maintenance

You can avoid most unforeseen situations if you observe the recommended 
procedures at all times and if the operating environment is effectively controlled by 
performing all maintenance actions when they become due in the manner described 
in the Operator’s Manual.

e

See 

Maintenance actions

 on page C-8.

Information about the status of

the system

The system performs numerous checks. When a certain event has occurred or when 
an irregularity is detected, a message is generated. Messages are displayed in two 
ways: 

o

Immediate feedback on user actions is displayed in a 

pop-up message screen

. 

e

See 

Message screen

 on page D-5.

o

Information concerning a problem that occurred during operation is reported as 

alarm messages

 in the 

alarm monitor

.

e
