Attendance check with the 'IC' serves for immediate intervention. Events such as
technical deficiencies, 'Faults' and malfunctions can be investigated and possibly
remedied directly by the operating personnel.
If an event is not acknowledged within the configured timespan (e.g. up to one
hour), an external intervention station is informed (global alarming).
The ↑ remote transmission for 'Faults' is not interrupted by the acknowledgment.
The external intervention center is also informed when the 'Fault' is acknowledged
but the cause of the 'Fault' is not rectified after a specified time.
This is ensured by parallel checking by the intervention center.
Intervention monitoring is used to safeguard a service intervention. Events such as
a 'Fault' caused by a soiled detector are monitored during a preconfigured period of
time (up to one week).
If the normal operation conditions are not re-established within this period of time,
service intervention is started and/or the maintenance personnel are informed.
●
A 'Fault' activates ↑ local alarming and starts the time t1 for attendance check.
●
Operating personnel acknowledge presence on the operating terminal prior to
the expiry of t1. Acknowledging silences the local ↑ alarming equipment. If
there is no acknowledgment, ↑ global alarming is activated after the expiry of
t1.
●
The time ts for service intervention monitoring starts in parallel to the time t1. If
the 'Fault' is not eliminated prior to the expiry of ts, maintenance personnel are
called up.
A triggered intervention process (t1 and/or ts running) is not restarted when a
'Fault' of the same category occurs for a second time.
The figure below shows an exemplary intervention process for the 'Fault' event
category.
