TO WHAT AND WHY IT APPLIES FOR • The standard diagram applies for a detector part where some HV channels are connected ;•It aims to reduce the HV ramping-up time;•The HV control program has to provide intersystem software interlocks:HV-LV-, majority condition on the tripped channels for the error recovering; enabling/disabling channel configuration;……..

13.2. Alarm Handling from the JOCOP FW sub-project guidelines and convention document

Following the guidelines of the AWG the intention of an alarm is to bring an anomaly situation to the attention of an operator and as such alarms are considered to be messages which are displayed to the operator via the alarm display and that are logged. An alarm does not initiate an action. Should an action be required then this should be handled within the FSM.

An alarm has several properties:

· Its Origin, which is used to identify the source of an alarm.

· Whether or not the alarm requires acknowledgement.

· Its Severity Level, which is used to characterise the seriousness of the alarm.

· Its Dependencies on other alarms.

· Certain Additional Details about the alarm.
