Related additional sensors
Additional information specific to pneumatic/hydraulic stored energy systems are often
requested, for example:
- AC supply voltage to the pump
- Pressure in pneumatic/hydraulic storage tank
This information can be monitored using sensors connected to the generic analogue channel
inputs. Please refer to section 12 for more details.
Values for these additional sensors can always be displayed in the HMI and alarms set. But
the interesting feature is that the additional sensors relating to the pump operation can be
grouped on the pump HMI page for ease of viewing. This is done by selecting which of the
generic channels (1 to 4) are relevant to display in the pump page:
HMI: Measurement / Settings / Pump
As an example, if we connect the sensors that give us the above-mentioned information to
generic channels 2 and 3 and we select these 2 channels to be displayed as part of the pump
data, then we would see the following information in the HMI:
HMI: Measurements / Pump
The description and the units associated with the generic channels are configurable. See
Section 12 for more details.
These selected generic values can also be stored in the "pump" COMTRADE file. See Section
12 for more details.
Note that when generic channels are selected to appear in the "Measurements/pump" page
of the HMI, they no longer appear in the "Measurements/Sensors" page of the HMI.
