The "system" temperature is measured on the AUX-PS module and can be used for over-temperature protection (OTP).

 

SCPI

MEASure:TEMPerature? AUX

 

OTP active

Enable or disable over-temperature protection associated with the system (AUX) temperature sensor.

bb3_man_temp_fan_settings.jpg

 

 

SCPI

SYSTem:TEMPerature:PROTection:STATe

 

Trip level

Set the over-temperature protection (OTP) value in degrees Celsius (oC). Default value for this sensor is 45 oC.

 

SCPI

SYSTem:TEMPerature:PROTection {<temperature>}

 

Trip delay

Specifies how long the temperature should be equal to or higher than the set trip level for the protection to activate.

 

SCPI

SYSTem:TEMPerature:PROTection {<temperature>}

 

Clear trip

When protection is activated (tripped), this condition will be latched and further usage of the EEZ BB3 will be disabled until protection is cleared.

 

SCPI

SYSTem:TEMPerature:PROTection[:HIGH]:CLEar

 

Fan speed

Current fan speed indicator stated in rpm (revolutions per seconds). The diagnosed fan fault will be also displayed here.

 

Fan mode

The fan is controlled by default with firmware algorithm (Auto mode) that takes into account measured temperature on all temperature sensors and measured output currents (i.e. the higher the output current, the sooner the fan speed will increase).

 

Manual mode can be selected for e.g. fan testing purpose when firmware speed control algorithm is completely bypassed.

 

Set speed to

This option becomes available when manual mode is selected. Default value is 100 % (full speed).

 

SCPI

SYSTem:FAN:STATus?

SYSTem:FAN:SPEed?

 

8.6. General trigger settings

The BB3’s triggering system allows a change in output state, voltage and current or start internal data logging when receiving a trigger from selected trigger source.

 

One common triggering system is used to control all available channels, but will only affect those channels that are not in Fixed trigger mode (see Channel trigger settings for channel trigger mode settings).

bb3_man_general_trigger2.jpg

 

Source

  • Bus – enables LAN and serial (via USB) triggering using the *TRG command. When this mode is selected, TRG text will blink when you turn on channels that have triggers defined (e.g. List or Step).
  • Immediate – the EEZ BB3 executes a complete trigger operation immediately after executing the INITiate command without delay.
  • Manual – allows you to manually trigger with the User SW (if assigned this function, see User SW) or by selecting the flashing TRG text that will appear on the screen as it shows the example in the picture to the right (Ch2 to Ch4 have triggers defined).
  • Pin<n> – selects a digital port pin configured as a trigger input. <n> specifies the pin number.

 

 

bb3_man_man_trigger.jpg

 

SCPI

TRIGger[:SEQuence]:SOURce {<source>}

 

Delay

Sets the time delay between the detection of an event on the specified trigger source and the start of any corresponding trigger action on the channel output.

 

SCPI

TRIGger[:SEQuence]:DELay {<delay>}

 

Initiate continuously

This option defines whether the trigger system is continuously initiated or not. When set to OFF, the system remains in the IDLE state until it is set to ON or an INITiate:IMMediate command is received.

Once it is set to ON, the trigger system will be initiated and exit the IDLE state. On completion of each trigger cycle, the trigger system immediately commences another trigger cycle without entering the IDLE state.

When this option is set to OFF, the current trigger cycle will be completed before entering the IDLE state. The return to IDLE also occurs as the result of an ABORt or *RST command.

 

SCPI

INITiate:CONTinuous {<bool>}

 

Initiate all triggers on DLOG start

This option allows all resources for which the trigger is not set to Fixed to be activated with the start of data logging. Once data logging starts, it is possible to change the trigger mode of resources without affecting data logging.

 

8.7. Ramp & delay

This page will show all output channels that have support for ramp and delay.

bb3_man_ramp_settings.jpg

 

 

Select the channel you want to define ramp and delay settings for.

 

bb3_man_ramp_settings2.jpg

 

 

Tap on the parameter that you want to set (e.g. voltage).

 

bb3_man_ramp_setting3.jpg

 

 

The graph above the list shows the output profile of the selected channel.

 

bb3_man_ramp_settings4.jpg

 

 

The channel list will reflect coupling in series. For example, the voltage ramp is able to be set at twice the value (up to 80 V).

 

bb3_man_ramp_series.jpg

 

 

This screenshot shows an example of a complex ramp and delay setup where the first two output modules are coupled in parallel and the last two modules turn on after a delay of 20 ms.

 

bb3_man_ramp_parallel.jpg

 

 

8.8. Tracking

Tracking is a convenient way to manage two or more channels simultaneously, i.e. there is no “master-slave” configuration, when changes can only be made via the master channel.

Only one tracking group can be set up. Channels that are in the tracking group will be able to define the following parameters at the same time:

  • Output set current and limit
  • Output set voltage and limit
  • Output power limit
  • OCP, OVP, OTP and OPP parameters (activity, delay, status)
bb3_man_tracking.jpg

 

  • Tripped protection clear
  • Trigger type, source and delay
  • Output list definitions (dwell, current, voltage)

When channels are in a tracking group, some of their options will be disabled (e.g. calibration). The Untrack option can be used for clear selections and will become visible only if two or more channels are selected.

 

SCPI

OUTPut:TRACk[:STATe] (@<chanlist>)

 

8.8.1. Power outputs coupling

Coupling provides a safe and convenient way to combine power outputs to increase capacity and offer output configurations.

 

Four power relays are used to combine the power outputs, avoiding the possibility of poor connections or accidental loss of connection, which could have detrimental effects on the connected load.

 

bb3_man_coupling.png

 

Furthermore, in the case of coupling into series or parallel, when doubling the output values, this will be taken into account, thus avoiding errors in the interpretation of the set and measured values.

By default all outputs are independent, i.e. separated from each other and “floating” or isolated in reference to MCU ground or PE (Protection Earth) potential.

 

Please note that regardless of the set coupling mode all channel outputs will remain isolated from the MCU ground and PE.

 

SCPI

INSTrument:COUPle:TRACking NONE

 

Series

Coupling is series is only possible between DCP405 modules on the first two slots. When coupled, the output connectors of the module in slot 2 will be disabled, and the output voltage on the connectors of the module in slot 1 will be able to be set to twice the value (i.e. 80 V for DCP405).

 

The maximum output current will remain unchanged (5 A).

 

bb3_man_coupling_series.jpg

 

Access to the module in slot 2 will be disabled on display. All set and measured output voltage and power values shown on the display for the module in slot 1 will be doubled.

 

Please note that according to many standards, voltage of 50 V and above are considered to be hazardous regardless of additional factors such as air humidity and temperature, skin moisture, etc.

Take all necessary precautions when the set output voltage exceeds this value.

 

SCPI

INSTrument:COUPle:TRACking SERies

Parallel

Coupling is parallel is only possible between DCP405 modules on the first two slots. When coupled, the output connectors of the module in slot 2 will be disabled, and the output current on the connectors of the module in slot 1 will be doubled (i.e. 10 A for DCP405).

 

The maximum output voltage will remain unchanged (40 V).

 

bb3_man_coupling_parallel.jpg

 

Access to the module in slot 2 will also be disabled on display. The set and measured output current and power values shown on the display for the module in slot 1 will be doubled.

 

SCPI

INSTrument:COUPle:TRACking PARallel

 

Split rails

This type of coupling is similar to serial coupling except the output of both channels is still active and the coupling between the first and second channels is used as a common ground. In this way, a symmetrical output is obtained where Vout + of the first channel represents a positive rail and Vout of the second negative rail.

 

 

 

bb3_man_coupling_srail.jpg

 

Channels can still be individually controlled, but since this configuration often requires the same output values (e.g. for powering operational amplifiers) a default is offered that places these two channels into a tracking group.

 

SCPI

INSTrument:COUPle:TRACking SRAil

 

Common GND

This is the simplest way of coupling the output and results in the connection of Vout- all channels on all slots to a common potential.

As mentioned in the beginning, the Vout- coupled output potential will still not be at the MCU ground or PE potential.

 

This coupling is not required for Vout- connections between two channels on the DCM220 or DCM224 because they are already internally connected.

8.9. Digital I/O settings

Two protected/buffered digital input pins plus two digital output pins are available on the EEZ BB3 front panel. Their function and polarity can be set on this page which also displays their current state.

 

Function

Input pins may be assigned with one of the following functions:

  • Input – The pin is in digital input mode.
bb3_man_io_settings.jpg

 

  • Inhibit – When pin is configured as an inhibit input, a true signal at the pin will disable all power output channels.
    If the channel outputs were turned on, all output values will flash in red when entering inhibit mode, as shown in the figure to the right.
  • System trigger – When configured as a trigger input, the pin can be selected as the source for trigger signals.
  • UART RX – The pin becomes a UART receiver (see subsection 8.10.1 below).
bb3_man_inhibited_view.jpg

 

Output pins could be assigned with one of the following functions:

  • Output – The pin is in digital output mode.
  • Fault – pin functions as an isolated fault output. The fault signal is true when any output is in a protected state (from OCP, OVP, OTP, OPP) or Fan fault is detected.
  • Channel ON couple – pin synchronizes channel output state.
  • Trigger output – This allows a BUS trigger to be sent to any digital port pin that has been configured as a trigger output. A trigger out pulse (100 ms) is generated when the state is on and a bus trigger is received. A BUS trigger is generated using the *TRG command.
  • PWM – (Dout2, pin 4 only) when selected, a square wave will be generated with set frequency from 0.03 Hz to 5 MHz and duty from 0 to 100 %.
  • UART TX – The pin becomes a UART transceiver (see subsection 8.10.1 below).

SYSTem:DIGital:OUTPut:PWM:FREQuency {<pin>}, {<frequency>}

SYSTem:DIGital:OUTPut:PWM:DUTY {<pin>}, {<duty>}

 

Polarity

  • Pos – a logical true signal is a voltage high at the pin. For trigger inputs and outputs, positive means a rising edge.
  • Neg – a logical true signal is a voltage low at the pin. For trigger inputs and outputs, negative means a falling edge.

 

SCPI

SYSTem:DIGital:PIN<n>:POLarity {<polarity>}

 

State

Current state of all digital inputs and outputs are displayed in this section. If the pin function is not yet defined, the displayed state will be Unassigned.

 

SCPI

SYSTem:DIGital:OUTPut:DATA? {<pin>}

 

8.9.1. UART settings

Configuring a DIN1 pin for a UART will automatically change the DOUT1 pin function and vice versa. It is possible to define the UART operating mode as well as the communication parameters.

  • Buffer – data received via the UART is not interpreted as SCPI but stored in input buffer which can be retrieved by using the SYSTem:COMMunicate:UART:RECeive? query
  • SCPI – received data via UART will be passed to the SCPI parser and interpreted. In this mode, the external device can take control of BB3.
  • Bookmark – the received string will be added as a new bookmark to the active DLOG session.

8.10. Display settings

Display color theme selection, brightness, luminosity, animation duration and status of display can be selected on this page.

 

An option for entering screen calibration (that is run by default on first start) is also available.

 

bb3_man_display_settings2.jpg

 

Theme

The EEZ BB3 comes with three color themes that apply to every page. The default theme is Dark.

 

Anim. duration

Define how long the animation effect lasts when transitioning between pages. Default is 250 ms. Set this parameter to 0 ms if you want to disable the effect.

 

Brightness

Controls the intensity of the display backlight. The range of the parameter is 1 to 20, where 20 is full intensity and 1 is backlight off. Default value is 10.

 

SCPI

DISPlay:BRIGhtness {<value>}

 

Lightness

This parameter defines the lightness of displayed colors if they are represented in so called HSL color space (hue, saturation, lightness). By increasing this value all colors will appear “lighter” or washed away. Similarly, when decreased all colors will appear “darker” or more dull. Lightness is not affected when set to 10. However, due to limitation of the LCD display (color representation is reduced to 16-bit) a default value is set to 5 to effectively compensate color difference.

The effect of changing this parameter can be observed by the color of three screen “widgets” (Background, Status, Pop up).

 

Touchscreen calibration

Screen calibration is required to give the firmware the necessary information about its geometry, which will increase the accuracy of data entry.

 

Initiate this procedure as necessary if you notice that the accuracy of data entry is no longer satisfactory.

 

New screen calibration can be initiated

also by touching the screen anywhere and hold for more then 15 seconds.

 

SCPI

CALibration:SCReen:INIT

 

bb3_man_start_screen_cal-1.png

 

For a successful calibration, you have to use stylus or similar rounded tip object and touch the three dots on the screen as accurately as possible.

 

bb3_man_start_screen_cal1-1.png

 

After successfully defining the three points, a new page will appear where you can choose between saving calibration data, repeating or canceling the calibration.

 

On the same screen is possible to test precision by touching the surface beyond the options mentioned.

bb3_man_screen_cal_finished-1.png

 

Turn display off

By turning display off user interaction is no longer possible. To reactivate it, you have to touch and hold anywhere on the display for a short time.

 

SCPI

DISPlay OFF

 

Test

Display test is used to detect defective pixels (aka deal pixels).

After the initial message, with each subsequent touch, the entire screen will be painted in primary colors (red, green, blue) following by white. It will be easy to notice if any of the pixels are defective.

bb3_man_display_test.jpg

 

 

Overlay

Determines whether overlay information is displayed or not. When set to Visible then overlay information will have the option to Minimize or Hide.

If Hide icon is tap and hold for 3 seconds the overlay menu will dissapear and Overlay state will be changed to Hidden. Here you can make it visible again.

When Minimize is selected the icon will change to Maximized and the overlay information will remain visible on the screen in minimized form.

bb3_man_overlay_max.png

 

 

8.11. Labels & colors

Displays a new page where you can customize the labels and colors of the currently installed modules.

 

Change label

It is possible to define a label for each module. The default label is the name of the module and the ordinal number of its resource (eg DCP405 # 1 if the DCP405 power module is installed in slot 1).

Selecting this option will display the keyboard for entering a new label up to 10 characters long.

bb3_man_labels_colors1.jpg

 

 

In case the peripheral module has additional resources (e.g. relays, analog and digital inputs and outputs) that can be labeled, an additional option will appear to access such resources as shown in the figure on the right when for example PREL6, SMX46 and MIO168 modules are installed.

 

SCPI

SYSTem:SLOT:LABel {slot}, {label}

 

Pick color

The header and frame module or resources (as in the case of a DCM module that has two) displayed on the screen will get a default color that can be replaced with one from the 24 color palette.

 

Once the color has been changed on a new arrival on this page, the Default option will also appear at the bottom in case you want to return to the original color.

 

SCPI

SYSTem:SLOT:COLor {slot}, {color}

bb3_man_labels_colors2.jpg

 

 

IMPORTANT: Changes to Labels & Colors depend on the user profile selected. If it is Profile 0 and you want the changes to be visible during the next power up then make sure that the Autorecall on Power-on option is set (see User profiles).

SCPI

SYSTem:COMMunicate:NTP {<server>}

 

8.14. Encoder & User sw

Confirmation mode

The encoder comes with a tactile switch and if this mode is selected then it will be used to confirm the newly changed value. By definition, the mode is not enabled which means that pressing the switch will instead move the "cursor" to the next editable field.

 

 

 

bb3_man_encoder_settings.jpg

 

Acceleration sensitivity moving up/down

The rotation speed of the encoder is measured and defines in what steps the selected value will change.

The reaction (sensitivity) to increasing the rotation speed in one direction or the other (increasing values or decreasing values) can be set by these parameters.

 

User switch action

Opens a menu with functions that can be assigned to the user switch on the front panel. See User SW.

 

8.15. Scripting

On this page it is possible to define which MicroPython script will run on the startup.

 

Auto start script:

The name of the MicroPython script to run.

 

 

 

 

 

bb3_man_autostart1.jpg

 

 

When the name field is selected, the contents of the SD card Scripts folder are displayed by default.

 

 

bb3_man_autostart2.jpg

 

 

The currently defined script can be replaced with another by tapping the script name. Use the X button to completely remove the auto start script.

 

Important: the auto start script is saved in the user profile so it is possible to define different startup scenarios. If you change the name of the script, don’t forget to save it in the selected auto recall user profile (if profile 0 is not selected).

bb3_man_autostart3.jpg

 

 

Auto start confirmation required:

Use this parameter if you want additional confirmation of running the selected script on the startup.

 

If No is selected, then it will still be possible to skip the script on startup by pressing the encoder switch during startup (i.e. when the Welcome page is displayed).

bb3_man_autostart4.jpg

 

 

If the Yes option is selected, a dialog box will be displayed during startup.

8.16. System information

The page summarized various system information and contains a list of all recognized modules.

 

Total On time

Total active time of the EEZ BB3 (i.e. MCU module). Resolution is 1 minute and this information is stored every 10 minutes in non-volatile memory. Therefore it’s possible that up to

10 minutes is lost after restart caused by a power outage or ungraceful power shutdown.

Firmware

The EEZ BB3 (MCU module) firmware version number.

 

CPU module

The model name and version of the MCU module.

 

IMPORTANT: Here you can choose for which version of the MCU module the system firmware will be activated. In case of choosing the wrong version of the module BB3 will not be functional which can be manifested with various problems in communication with peripheral modules. If you are not sure whether the correct version is selected, you can find the version label on the MCU module itself, e.g. r2B4 or r3B3.

 

If after a reboot you have problems with the r2B4 MCU that you accidentally set to r3B3, check Troubleshooting section.
