3.0 Operation3.2 Main Display Drop-Down MenusThe drop-down menus are located in the header of the Main Display. The drop-down menus consist of: File, Setup, Com and Help.

The File MenuFrom the File menu, file management software tools can be accessed. The File menu consists of: Install, Save and Exit.

File > Install: Opens the NetDyn file installation menu. SuperFlow recommends installing files using the WinDyn Software system, so this menu items is not typically used.

*File > Save: Opens the NetDyn file save menu. Current sensor calibration data may be saved from this menu option within NetDyn.

File > Exit: Closes the program and returns the operator. The program can be opened from the computer running the WinDyn and NetDyn software.

The Setup MenuThe Setup menu consists of: Test Setup, Channel Calibration, Control Setup, System Limits, Auto Zero Channels, Erase Recorded Data, System Configuration, License Manager, Touch Screen Mode, Screen Toggle, Filter and Test Setup Configuration.

Setup > Test Setup: This menu item is normally not accessed from the NetDyn interface. Test Setup should be done through the WinDyn Test Setup window. Refer to the WinDyn Operators manual for more information. Pressing or clicking Test Setup will activate the Test Setup dialog allowing for the operator to select the desired test and Safety Limits, set the test parameters, and enter the correct Specification values.

6

3.0 OperationSetup > Channel Calibration: This menu item is for Sensor calibration, which may be done through NetDyn. NOTE: This is the only option to calibrate by coefficient for

engine dynos. Pressing Channel Calibration will display the sensor calibration screen. Every channel defined in the configuration file (CFA/CFD) as a calibrated channel is shown.• AutoZero All: Sets the current reading in each channel

defined to be “zeroed by local command” to zero (0). A prompt appears to confirm the action. Zeroing compensates for atmospheric condition changes or sets the proper zero reference in channels that do not have the correct offset in the calibration file.

• Done: Closes the calibration dialog.To calibrate a particular channel, Press, double-click, or right-click on the desired channel to access the calibration options.• By Current Value: Allows to calibrate the

channel using a known input.• By Coefficient: Allows to calibrate the channel

using a known coefficient value.• Default: Allows to calibrate the channel to the

settings in the system configuration file (CFX/CFA).

When a channel has been calibrated, the new coefficients should be saved. Calibration coefficients are maintained in a special WinDyn file. The calibration can be saved by selecting File > Save > System Calibration on the NetDyn File menu.Autozero will set the current readings of all sensor channels to zero (0) providing they are set for a Global zeroing in the system configuration file (CDA/CFX).Exit will close the calibration menu.

Setup > Control Setup: This menu item is for Control parameter adjustments, which must be done through NetDyn for engine dynos.SuperFlow dynamometer systems provide closed-loop servo control to maintain a desired set point. The normal type of control is by digital Proportional, Integral, and Derivative (PID) software parameters.

Control Setup• Controller: Selects one of the two available controllers. The name displayed is determined in the active

system configuration (CFX/CFA).• Phase: The actuator (the device connected to the controller) phase determines the actuator direction

of travel as a response to the controller output signal. A “1” inverts the signal. If the actuator phase is 0, the actuator goes from 0 to 100% when the controller output signal goes from 0 to 100%. If the actuator phase is 1, the actuator goes from 100 to 0% when the controller output signal goes from 0 to

Always be certain to have a known input applied to the sensor before entering a current value. Zero (0) is not a valid calibration value and will corrupt the sensor calibration. Entering a coefficient other than one obtained from an actual calibration will result in erroneous readings.

IMPORTANT

100%. The actuator phase must be correctly selected to properly drive the control mechanism on the test system (allowed values: 0 or 1).

• Step Setting: Sets the Coarse, Medium, and Fine steps for the controller output in manual mode. These are the steps seen when pressing the F8, F9, F10, and F11 function keys.

Control PID Setting• Mode: Selects the desired control mode as defined in the active system configuration (CFX/CFA).• Phase: The controller phase (allowed values: 0 or 1) determines closed-loop control polarity, i.e., the

direction of movement of the controller output as a response to a change in the feedback signal from the control channel. If the controller phase is 1, when the feedback signal increases, the controller output signal will increase. If the controller phase is 0, when the feedback signal increases the controller output signal will decrease.

NOTE: The controller phase must be properly determined before the controller phase is set because the actuator phase also has an impact on the aggregate polarity of the closed-loop control system.

• Step Setting: Sets the Coarse, Medium, and Fine steps for the controller output in the selected mode. These are the steps seen when pressing the F8, F9, F10, and F11 function keys.

• PID: The control parameters that determine the reaction and stability of the controller.

Only trained and experienced technicians should set and tune the digital PID values. Therefore, a detailed description of these parameters is omitted from this manual. If it is necessary to adjust the PID values, contact SuperFlow Customer Service for assistance.

! CAUTION

Setup > System Limits: This menu item is used to switch safety limits ON and OFF, which must be done through NetDyn or a test profile.WinDyn provides a Limits safety system that can assume the task of monitoring the engine or vehicle for conditions that may result in a catastrophic event. Examples of these conditions are low oil pressure or high coolant temperatures. WinDyn Limits provide automatic warning and shutdown actions that are initiated when a programmed channel value reaches its assigned limit.Limits files are created with the WinDyn Limits Profile editor and saved on the computer as *.lmt files. The editor assigns the channel limits as well as the warning and shutdown actions. These files can then be embedded into a Set File and uploaded to the test system CPU where it is stored flash memory.

Setup > Auto Zero Channels: This menu item allows the operator to zero sensor channels.

3.0 Operation

Setup > Erase Recorded Data: Displays the Erase Memory dialog allowing to erase all data from memory or just the last line recorded

Setup > System Configuration: This menu item allows low level configuration of system and is intended for SuperFlow personnel use only. This area is passwork protected, operators can not access without assistance.

Setup > License Manager: This menu item accesses the system licensing options, which must be done through NetDyn for engine dynos.

Setup > Touch Screen Mode: This menu item allows the operator to enable/disable touch screen mode. When the option is enabled, pressing or clicking a field requiring a numerical entry will display a touch pad keyboard on the screen. If disabled, the computer keyboard is used to enter number values.

Setup > Screen Toggle: This menu item allows the operator to switch between the Main Display and Alternate Display discussed in section "3.1 The Main Display Window" on page 4.

Setup > Filter: This menu item is normally not used. Filters are typically established in the test profiles.

Setup > Test Setup Configuration: This menu item allows for use with legacy product and is not enabled for current products.

Once data has been erased, it cannot be recovered.

! CAUTION

System Configuration Settings should only be changed when authorized by your representative.

The Com MenuThe Com menu consists of: Disconnect/Connect, Port Setup and System Pairing.

Com > Disconnect/Connect: This menu item is used to Disconnect or Connect the NetDyn software from the SuperFlow system.

Connecting NetDynWhen NetDyn is turned ON the Status bar at the bottom of the display will show “Not Connected”. Pressing or clicking the Com > Connect will prompt NetDyn to query the network looking for a compatible system to communicate with. If only one system is currently on the network, NetDyn will automatically connect to it. If more than one system is available, a dialog will appear prompting the operator to select the desired system. Once NetDyn is connected, the Status bar at the bottom of the display will show the test system name and serial number. The box next to the serial number is a frame counter indicating ongoing communication (the actual number in the box is meaningless other than to show activity).NOTE: The default system name is SuperFlow and is set in the network configuration on the test system

CPU. Name changes can be done by a qualified SuperFlow Customer Service technician. The serial number is set at the factory and cannot be changed.

Com > Port Setup: This menu item allows the operator to set the network communications port number. The default TCP/UDP port is 54321, DO NOT CHANGE without authorization by a qualified SuperFlow representative. NetDyn uses standard TCP/UDP communications protocols for computer networking. This type of networking uses ports that serve as a communications “endpoint”. A specific port is identified by its number, the IP address with which it is associated, and the protocol used for communication. SuperFlow has optioned to use the number 54321 as the port number for NetDyn. This number is embedded into the test system CPU at the factory. Contact your SuperFlow representative if you suspect this number needs to be changed (possibly because of conflict with another device with the same number).

Com > System Pairing: This menu item allows NetDyn to be paired with a SuperFlow system. Normally used in facilities with multiple SuperFlow systems.

PairingIf more than one SuperFlow test system is on the network, NetDyn can be set up to only connect to one of them every time without prompting for a selection. Press or click Com > System Pairing, the System Connection (Pairing) dialog box will appear. Select the desired option and press or click Done.• None - always scan for system - The default pairing option.• Pair with S/N - The known serial number of the unit must be manually entered.• Pair with current system - Displays the unit that NetDyn is connected to (this option will not be shown

if NetDyn is not connected to a system).Once NetDyn is paired with a particular test system, it will always automatically look for and connect to that system only, regardless of how many system are available. The pairing options can be changed at any time.

3.3 Dynamometer ControlsDynamometer controls are accessed from the NetDyn Alternate display or by the function keys on the computer keyboard. These buttons are configured as on/off or momentary switches and activate digital outputs in the sensor box. The function of these switches is set in the low-level configuration for the system type and cannot be changed.There are four buttons typically associated with dynamometer controls. However, all four are not always used. The F6 soft key and function key are programmed to record one line of data when pressed.

Figure 3.4 - Example of the Alternate Display

• F1 Ign: An on/off switch command that activates the engine ignition output on an engine control panel or relay box. It also controls the magneto output on an engine control panel.

• F2 Fuel: An on/off switch command that activates the fuel pump output on an engine control panel or relay box.

• F3 Start: A momentary switch command will activates the starter output on an engine control panel or relay box.

• F4 Fan: An on/off switch command that activates the auxiliary output on an engine control panel or relay box.

3.4 Status BarThe status bar located at the bottom of the screen provides useful information about how the system is set up and current events.

Figure 3.5 - Status Bar

• Connected To: Name and serial number of the test system NetDyn is connected to. These are assigned at the factory.

• Data Updates: The box next to the serial number is a frame counter indicating ongoing communication (the actual number in the box is meaningless other than to show activity).

• Config: Name of the configuration file installed. If the box is empty, the system is turned off or is not communicating.

• Test: Name of the autotest file installed. If the test is running, the current step number it is on will be displayed.

• Limits: Name of the limits file installed.• Recorded Data Lines: Number of data lines currently in the memory buffers.

3.5 Dyno Testing with NetDynRunning a test on a SuperFlow test system involves two steps. First prepare WinDyn for the test, and second, execute the test itself using NetDyn. Post-test analysis is performed with the WinDyn Stored Data Viewer.

WinDyn Test SetupIn most situations, data recorded in a WinDyn scripted test will be automatically saved to the computer on which WinDyn is running. In order for the data to be saved with the proper file name and to the proper location, WinDyn must be first prepared. Test Setup is done through the WinDyn Test Setup window allowing for the operator to select the desired test and Safety Limits, set the test parameters, and enter the correct Specification values.For information on the WinDyn Test Setup procedures, refer to the Windyn Users Guide.If WinDyn is not used with the test system or if the test does not automatically save data, presetting the file name and location is not required.

3.0 Operation

13

Figure 3.6 - Example of the Main Display

Running an Automated TestOnce an autotest is selected and the test parameter set, the test is started by pressing or clicking the Start button. The red Stop button will also abort the test.Messages will be displayed in the Test Message showing the test status or prompting the operator to do things as required by the test. These messages and prompts are scripted in the test profile.

Figure 3.7 - Soft Keys

The buttons below the message area are referred to as “Soft Keys”. These keys are programmed in the test profile to perform specific functions when pressed. The line and spaces in the message directly above the buttons will show what the button is programmed to do.As an autotest is running, some functions on the NetDyn display will be locked out from operator access. The most prevalent of these is the load and throttle controllers.When the test is completed or aborted the display will return to manual operation.NOTE: See the chapter on Test Profiles in the WinDyn Users Guide for more information on automated

tests and how they are programmed.
