3.3.1 ALARM CONFIGURATION ON VMU-P MODULES
Each VMU-P module can manage specific alarms for each of the monitored dimensions :

Channel 1 temperature

Channel 2 temperature

Analogue input (mV or mA)

Pulse rate input
VMU-P alarm configuration mask
For each alarm you can define the activation thresholds and the relevant usage mode:
-
Rising alarm: Threshold1 ≥ Threshold2
- Dropping alarm: Threshold1 < Threshold2
Each alarm can be disabled, or be enabled as a Virtual Alarm, or you can link each
individual alarm to a digital output
VMU-P alarm configuration mask
Each alarm can be associated with a different “Alarm activation delay filter” value (a
value expressed in seconds, which can range between 0 and 3600).
To configure the alarm triggered by the “analogue input” and by the frequency input
(pulse input), besides the alarm thresholds Threshold1 and Threshold2 you also need to
set the data specific to the installed sensor:

Electric scale
– Minimum Value (mV): parameter related to the electrical input
(minimum value of the input signal).

Electric scale
– Maximum Value (mV): parameter related to the electrical input
(maximum value of the input signal).

Displayed scale
– Minimum Value: Minimum value (expressed in the engineering
unit specified above) at the minimum input value (mV).

Displayed scale
– Maximum value (expressed in the engineering unit specified
above) at the maximum input value (mV).
