VELO Cooling Troubleshooting


 

Introduction

In case of problems with the cooling system you first have to find out what is causing the system not to do what it is supposed to do. Is the main power gone and is the system running on diesel power, is the chilled water not present or perhaps too warm ?? Most likely you will find the issues on the Alarm page and/or Warning page of the cooling PLC.

UPS of the cooling system

The cooling system has its own UPS. The most relevant settings of this UPS are given in this tar-file.

 

 

Common problems for which you get a call

 

Cooling alarms when switching between states

When LV is turned on some cooling conditions might hit the warning levels, this is temporary and should recover soon.
If the experiment is switching from a state to another, for example from "MD" to "INJECTION", these alerts are masked for 10 minutes. However if the configure command is only given after this period, then the alarms are not masked.
In this case monitor the cooling for about 10 minutes and it should recover by itself. (See plot)
