5.3.1 Alarms that are over
Alarms that have been activated and for which the alarm conditions have ceased to exist are considered alarms
that are over. For an alarm that is over RICS displays the initial occurrence, the duration and other associated
information, until the alarm is reset (see paragraph 5.3.5). This means that the last anomalies or critical
situations measured are easily accessible, without forcing the operator to search for them amongst the historical
data.
It is enough to bring up the Alarm manager Page to verify whether there have been any problems in the plant.
5.3.2 Alarms with automatic deactivation
Normally alarms in RICS are automatically deactivated. This means that when the reason behind the alarm
ceases, the alarm is deactivated by the software. In this case the alarm is given the status of alarm over.
5.3.3 Alarms with manual deactivation
This function is only available on RICS Top Edition.
You can set RICS so that an alarm requires manual deactivation. This means that when the cause of the alarm
ceases to exist, RICS maintains the alarm signal until it is manually deactivated. Normally this corresponds to an
inspection by a member of staff.
5.3.4 Alarms with manual deactivation counter
This function is only available on RICS Top Edition.
You can set RICS so that an alarm is considered normally as an alarm with automatic deactivation, unless it is repeated
over a certain period of time, at which point it will require manual deactivation.
An example of use is the following: A maximum pressure manostat measures alarm conditions occasionally (if over-
loaded), thus protecting the machine. Upon the restoration of normal operating conditions the machine is reactivated,
and the alarm signal is deactivated. RICS copies the machine’s diagnostics by deactivating the alarm signal too. If
however the alarm is repeated regularly, this is an indication of a problem in the machine or the plant. In this case, RICS
maintains the alarm status even when the reason behind it ceases to exist.
5.3.5 Manual global Reset of all alarms
In the Alarms manager window menu, in Action>Reset all alarms, you can reset the status of all alarms
(counters of the number of activations, times etc…) of all the devices. This decision cannot be cancelled and can
only be performed by users with a certain user profile.
The alarm reset also deactivates a manual alarm whose cause has ceased to exist.
