In this guide you will learn how to add configurable inputs to devices in Leanheat® Monitor, what each input type does, and how to compare the same input across several devices.
Inputs on the ECL296/310 that are not used by the application can be used as extra configurable inputs.
Adding a configurable input
Navigate to the "Devices" tab and select the device. Above the flow diagram click "Options", which is the first tab from right to left, and select "Configurable Inputs". The list shows the inputs the device already has, and each row has an actions menu on the right. To add one, click "New Configurable Input".
The wizard has two steps. In "Select sensor input" enter the "Input name", select the "Sensor" (the terminal the input is wired to), select the "Type" and choose one of the "Options". Click "Next".
In "Configure" fill in what the selected type needs and click "Save". What appears here differs per type, and the sections below cover each one.
The sensors and types you are offered depend on the application, subapplication and version the device is running, so an input that exists on one device is not necessarily available on another. In the list, the "Application information" column shows whether an input is applicable to the device it sits on.
A configurable input cannot be added or changed while the device is offline. The "New Configurable Input" button is disabled and a message explains why.
Readouts for the configurable input are being stored from the moment the input was added in Leanheat® Monitor. You can view the historic values for the input in the "Readings" and "Graph" tabs.
To add the configurable input to the device flow diagram contact your local support.
Configurable input types
Pt1000
This input type is used to add Pt1000 sensors as configurable inputs to the ECL.
0-10V ADC
This input type is used to add a 0-10V sensor as a configurable input to the ECL. In the second step choose the "Quantifiable", which is the physical quantity the sensor measures, for example water pressure. The "Unit" list below it then offers only the units that belong to that quantity, so pick the quantity first and the unit second. Finally enter the "Min" and "Max" value of the sensor.
Digital
This input type is used to add a digital input as a configurable input e.g. pump alarm, switch, etc. to the ECL. When adding a digital configurable input it is necessary to enter the "Closed circuit label" and "Open circuit label". These are the texts shown in "Readings" and "Graph" when the circuit is closed or open, instead of "0" and "1", for example "door closed" and "door open".
Pulse
This input type is used to connect the pulse output of an energy meter to the ECL. Choose the "Quantifiable" the meter counts, normally energy or volume, and then the "Unit" that belongs to it. Enter the "Equivalence" and "Pulses". For example if equivalence is "1", pulses is "10" and the selected unit is "kWh", then 10 pulses equal 1 kWh of energy.
Frequency
This input type is used to add a frequency input as a configurable input to the ECL. A frequency input measures only one quantity, so the "Quantifiable" and "Unit" are already filled in as frequency in Hz and there is nothing left to configure.
Flow switch
This input type is used to add a flow switch as a configurable input to the ECL. As with a digital input it is necessary to enter the "Closed circuit label" and "Open circuit label", which replace "0" and "1" in "Readings" and "Graph".
Configurable input options
The option is set in the first step of the wizard and controls how the terminal behaves. Four options exist, and each one shows a short explanation in the application when you hover over the question mark next to it.
- None: no options.
- Pull up: the input will read a high state (1) when the circuit is open and a low state (0) when the circuit is closed.
- Cap load: enables a capacitor load. This is used to keep mechanical contact points clean.
- Pull up & Cap load: both of the above at the same time.
Adjustments
Adjustments are only available for pulse inputs. A pulse input counts upwards, so it measures an accumulating value such as volume or energy. If the meter you connect is not standing at zero, the input would start counting from zero and no longer match the meter. An adjustment corrects this: you add the amount the meter already shows, so the value in Leanheat® Monitor continues from the meter reading instead of from zero.
Open the actions menu on the input and select "Adjustments".
Enter the "Adjustment amount" in the unit shown next to the field and click "Adjust". The dialog lists every adjustment made so far with its date and amount, newest first. Only the newest one can be removed again, using the bin icon on that row.
An adjustment applies to readings from that point on. Readings that are already stored are not recalculated, so the values you see in "Readings" and "Graph" for the period before the adjustment stay as they were.
Comparing an input across devices
Configurable inputs can be compared between devices in the device table, in the device table of an area, and in the station performance widget. This works even when the same physical measurement was given a different name on each device, because the inputs are matched by the terminal they are wired to and the quantity they measure, not by their names.
For that reason a configurable input appears in those comparison lists as the terminal and the quantity, for example "S8 - Temperature", rather than the name you gave it. Wiring the same kind of sensor to the same terminal on every device is therefore what makes a comparison meaningful.
Renaming and deleting
The actions menu on a row also holds "Rename configurable input" and "Delete".
When you delete, Leanheat® Monitor first checks whether the input is used anywhere else. If it is used in a virtual measurement it cannot be deleted, and the dialog lists the related measurements, which have to be deleted first. If nothing depends on it, it can be removed straight away.
