Section II: PABT-Specific Examples
To start Station: Double click the icon on the desktop
To log into Station: click anywhere on screen, and the Station Logon prompt will appear. Enter in your user name and password and click ok in order to log into the system.
To log out of Station: type “bye” into the command line in the Toolbar and press enter:
Once you log into Station, the Home Screen automatically appears:
The home screen contains the following components:
Floor Overview GUI
The navigation bar has five buttons:
Air Systems Menu
Water Systems Menu
Floor Overview Menu
Systems Overview Menu
Emergency Generator System
Click on any of these buttons to navigate to the screens associated with the them.
When clicking on the Air Systems Menu button, for example, the following cascade of menus appears:
Select the air system that you are interested in viewing and click on it. This will cause the page associated with that system to display.
In order to see floor overviews, one can select an item from the Floor Overview Menu, or one can use the Floor Overview GUI. To do so, simply hover the mouse over a specific region of the building on the home screen. When the name of that region appears, click on it in order to navigate to the floor overview page for that region. The example here shows one selecting Floor 3:
Once you select an item from the navigation bar, Station displays the custom display associated with that system. For example, if one selects AHU-S22-222 in the Air Systems Menu, the following display loads:
Notice that on the top right hand corner of the page, the unit name, the unit location, and the name of the panel that controls the unit are displayed:
Notice that every device has its associated tag adjacent to it on the display. These tags are identical to the tags in the TEC System submittal. The fan unit and high static differential pressure tag can be seen below:
The display on page 11 contains all of the data points associated with the unit AHU-S22-222. Points are arranged in clusters so that points that are logically connected are in close proximity to each other. For example, all of the points associated with the freeze protection pump (pump failure alarm, pump tamper alarm, pump start command, pump status, and outside air override on set point) are contained within the box surrounding the pump itself:
The same is true of the air handling unit:
Here is a breakdown of the different components contained on the display:
Unit Schedule Button
Unit Schedule On/Off Point
Unit Mode (Summer/Winter)
Temperature Set Point Box
Unit Reset Button
Outside Air Damper Status and Alarms
Filter Alarm Status
Mixed Air Temperature and Freeze Alarm Status
Chilled Water Valve Output
Air Handling Unit Data (Start Command, Status, Alarms)
Discharge Air Temperature and Set Point
Space Temperature and Set Point
Freeze Protection Pump Data/Hot Water Valve Output
In general, set points that can be changed by the user are contained within white boxes. Set points that are actively set by the system itself and are not to be changed by the user are contained within grey boxes. Analog input points (e.g. temperature reading) are displayed in larger fonts with no boxes around them.
User set point
Analog input point
Active set point (do not touch)
In order to adjust a set point, double click on the data point itself. This will bring up the Point Detail Page associated with that data point. Here is an example of the Point Detail Page for a temperature set point:
Here is a breakdown of the various components on this page:
Data Point Name
Alarm Status Flag
Fault Status Flag
Overridden Status Flag
Out of Service Status Flag
Relinquish Default Button
Out of Service Selector
Once on the Point Detail page, a set point can be changed by selecting the text in the Present Value field (1) and entering the new desired value (2).
Once you click somewhere off the Present Value field, the system will accept the new value and mode will change from Auto to Manual Override.
If you want to return the set point to its default value, click on the Relinquish Default button.
Just for reference, the basic types of data points used in EBI are:
The toolbar is a series of buttons on the top of the screen that provide navigation to commonly used pages or execute common functions. The following table provides an overview of every button contained within the toolbar:
Sometimes, an operator wants to search for a specific data point. This can be done by typing text into the text field on the end of the Toolbar. For example, if you want to see a list of all of the data points that contain the string of letters “temp” in their name, type “*temp*” into the field:
(The asterisks before and after tell the system to include data points that have characters before and after the string that was actually searched in the search results.) Then click on the Detail Search button or press F12:
Here is an example of search results for this type of query:
This is a list of all of the points in the system that contain the string “temp” in their names. Click on any of the search results to navigate directly to the Point Detail Page for that data point.
The status bar provides and overview of your system’s status. The following table describes each component of the Status Bar:
As explained in the previous section, there are two alarm indicators on the Status Bar:
The Alarm Summary page looks like this:
It contains a summary of all of the current alarms in the system, both acknowledged and unacknowledged.
If the same alarm occurs more than once before being acknowledged, its value contained in the count column is incremented.
Alarms are represented by status symbols:
In order to view the status or value of a point over a period of time, a history assignment has to be set up for that point. In order to do this, select the following options from menu bar: Configure > History > History Assignment. Then, select the appropriate history tab based on the resolution that you want to record with:
Later on, when setting up the actual trend display, you will be able to choose which log to display.
Once the history type is chosen, the actual data point that will be recorded must be chosen. Press the button, choose your desired data point from the Point Browser, and press Apply. Then, select the Parameter from the drop down menu. Unless the point is a multistate point, PresentValue should be chosen. Once this is done, the history assignment has been configured and the log will begin recording data.
Once a history assignment has been configured for a data point, one can view the logged data on a graph. In order to do that, navigate to point detail page for the data point, select the History tab, and the collected history with display. Here is an example of what it will look like:
If a standard or extended history assignment was chosen for this data point, one can switch between the different logs by using the Interval drop down menu.
The software logs all logins, logouts, faults, and system changes on the Event Summary Page. To navigate to the page, in the menu bar, choose View > Events > Event Summary. Events are listed in chronological order.
To view recent events associated with a specific data point, navigate to the point detail page for that point and click on the Recent Events tab.
The are 2 different ways to access to time schedule configuration for a specific system:
Click on the System Menu on the Toolbar, select Building Management > BACnet Schedules. Then select the schedule name for that system.
- or -
Navigate to the custom display for that system and click on the calendar button next to the words Run Schedule:
Select the Weekly Schedule tab to view or modify the schedule.
In the case that a schedule needs to be overridden for a certain period of time, such as a holiday weekend, an exception needs to be created. In order to do so, select the Exception Schedule tab. Right click on the screen and select Insert Period. Select a Period from the drop down menu. Select Priority 15 as the Priority for writing. Insert a time by selecting and time and value on the bottom of the page and pressing Insert. Select the time that you inserted and press Save.
In order to add operator accounts to the system, click on the System Menu button on the toolbar, select System Configuration > Operators. Click on the first available underscore and an operator configuration page will display.
Select Traditional Operator for the type and fill in the text fields and for username, full name, and job title. Press Change Password and assign the new user a password.
Set a Control level [0-255]
A security level for the new user must be chosen. The different available options and their respective capabilities are:
A control level must be chosen as well. This is compared to the control level associated with each individual data point. If a user’s control level is equal to or greater than the control level required for a specific point, they are granted access to it. By choosing 255 for a user’s control level, they receive access to all data points in the system.
In this next section, we will review the operation of unit AHU-S22-222, per the details contained in its sequence of operation. The following is the sequence of operation for this unit, as copied from TEC Systems’ submittal:
We will now parse through the sequence, explaining the more ambiguous details contained within:
“The air conditioning system shall operate based on an adjustable software time program (1) or manually by an operator at the workstation. The operator shall have the ability to override an automatic starting or stopping time period at the operator workstation (2) or the DDC control unit (3), or by utilizing the “Hand” selection at the respective fan starters.”
(1) This is accomplished by clicking on the unit schedule icon and configuring the unit schedule. See page 32, item 2 for details on this.
(2) This is done by overriding the unit schedule on/off point to the desired value, irrespective of what the unit schedule is commanding it to:
(3) This is done by using the override switches on the binary output modules on the panel (LCP-2-32):
binary output module
“When the fan system is not in operation (1), the existing outdoor air damper shall be closed (2). The existing normally closed chilled water coil valve shall be closed (3). The existing normally open heating coil control valve shall be under control of the DDC controller to maintain a minimum air temperature of 45°F in the heating coil discharge plenum (4), as sensed by a temperature transmitter on the leaving air side of the preheat coil section (4).”
From left hand pane:
Notice that while the unit is off, if the mixed air plenum temperature drops below 45°F, the heating coil modulates open to maintain the set point of 45°F:
“When the fan system start is initiated (1), the outdoor air damper shall open prior to fan start. Once the outdoor air damper is confirmed open through a damper end switch (2), the fan shall start and the temperature control system shall be activated (3). The DDC controller shall monitor the status of the outdoor air damper.”
“The Winter/Summer mode of operation shall be determined by a global Summer/Winter switch based on outdoor air temperature of 55°F (adjustable) such that the system shall operate in the winter mode below its set point and in the summer mode above its set point (1). The operator shall also have the ability to manually index the winter/summer mode of operation for the individual fan system from the operator’s workstation (2).”
(1) This is accomplished through a global control loop and cannot be changed from this display.
(2) This is accomplished by overriding the operation mode point to the desired setting, summer or winter. Notice that the set points for each mode differ and can be accessed by clicking on the winter and summer tabs:
“WINTER OPERATION: The cooling coil valve shall be closed (1). The supply fan shall operate at high speed (2), and the heating coil hot water circulation pump shall be active whenever the supply fan is active (3).
“The pump shall be off whenever the supply fan is off, but shall remain on continuously (1) whenever the outdoor air temperature drops below 35°F (adj.) (2).”
“A platform space temperature sensor (1) shall signal the DDC controller to reset the fan discharge temperature between 60°F and 80°F (adj.) (2) by controlling the heating coil valve to maintain the winter space air temperature set point of 68°F (adj.) (3).”
(2) One can adjust the min and max values for the discharge temperature set point reset loop by overriding the points in the left hand pane. Summer and winter modes have their own sets of min and max values so make sure to change only the points of interest. The active discharge temperature set point is displayed in the gray box in between the two set points and should not be overridden.
(3) The summer and winter space temperature set points are displayed in the left hand pane. The system displays the set point currently in use in the active set point field underneath the space temperature graphic.
Notice that while the system is in winter mode, if the discharge temperature falls below the active discharge temperature set point, the heating coil modulates open to correct this difference. The reverse happens when the discharge temperature rises above the set point:
“SUMMER OPERATION: The heating coil valve shall be closed, and the heating coil hot water circulation pump shall be off. The supply fan shall operate at low speed. The platform space air temperature sensor shall signal the DDC controller to reset the fan discharge temperature between 55°F and 70°F (adj.) (1) by controlling the cooling coil valve to maintain the summer return air temperature set point of 78°F (adj.) (2) .”
Notice that while the system is in summer mode, if the discharge temperature rises above the discharge temperature set point, the cooling coil modulates open to correct this difference. The reverse happens when the discharge temperature falls below its set point.
“SAFETIES AND ALARMS: The failure of the supply fan to start or remain on, or to stop or remain off, when commanded by the DDC system shall cause a “failed on-status” (1) or “failed off-status” alarm (2) to be generated at the operator workstations.”
“A pressure differential switch sensing the inlet suction of the supply fan, shall stop the supply fan
and shall transmit an alarm to the operator workstations, if the pressure set point is exceeded for
an adjustable time interval (1). The fan shutdown shall be operative whether the starter H-O-A
switch is in the "Auto" or "Hand" position. The fan shall remain off (2) until the system is manually
reset from the operator workstations (3) or from the local control panel system reset button (4).”
“A low temperature switch (freeze stat), located on the face of the cooling coil, shall stop the
supply fan (1), and activate the hot water circulating pump (2) (if not already on), should the air leaving the coil drops below 35°F for 180 seconds (adj.) (3). The fan shall remain off until the system is manually reset from the operator workstations or from the local control panel system reset
(4) The process of resetting the system is explained in slide 50.
“A differential pressure switch across the fan filter shall signal the DDC controller to generate an
alarm at the operator workstations should its alarm set point be exceeded for an adjustable time
