Transcription

1 Replaces: Functions of Control Panel BB-3 (VT 12321) when used with MC Microcontroller Diagnostics, Parameterisation, Process Value Display Version 1.6 MC7 and BB-3 Features The control panel BB-3 is used for communication with a variety of digital control devices from the Mannesmann Rexroth range. If the BB-3 unit is connected to such an output device, this will automatically be recognised and the relevant software in the BB-3 will start up. In addition to the general description of the BB-3 hardware in RE 29798, the special functions shown here are available when the control panel BB-3 is connected to a Brueninghaus Hydromatik MC microcontroller. The individual functions are as follows: Diagnostics Display of errors in clear text Parameterisation Input and editing of userspecific values, e.g. time ramps, pilot currents Process value display Display of actual values, e.g. speeds Teach Store and load edited or standard parameters Ordering Code (for BB-3, VT12321 incl. software) The functions required for a Brueninghaus Hydromatik MC microcontroller are contained in the BB-3 software under the following designation: (VT X/E-VX.X/X.X/X.X/1.6) or VT VX.X/X.X/X.X/1.6 Brueninghaus Hydromatik BB-3 Software Version 1.6 When connecting or disconnecting the BB-3 connecting cable the microcontroller MC has to be switched off! Special features User-friendly menu Easy input by means of numerical keys with edit functions Multi-lingual Online editing of parameters (while machine in operation) Reset to standard settings (defaults) possible at any time BB-3 1/12

2 1. Start-up functions After switching on the power for the control panel BB-3 the following functions are carried out and shown on the display (flow chart Fig. 1, page 10): 1.1 Self-test and baud rate recognition The BB-3 automatically recognises the rate of data transmission from the MC electronics. During this time the message 'not received' may be briefly displayed. * B B - 3 / B F - 1 * Ver s i on : XX XX XX 16 N.B.: As long as a key* is being activated while switching on, the software version will be displayed. (*exception: ALT key) If the BB-3 remote control unintentionally activates the "Test mode" (these displays are not shown or described here), this mode can be cleared by pressing and holding down the ALT + CLEAR keys simultaneously for a few seconds. * R e x r o t h B B - 3 * V 2. 0 ( RS422/RS232 ) ( XXXXX Baud ) * HYD - D i a g n o s e * (C) Hydromatik V Identification On recognition of the MC electronics the relevant software in the BB-3 will be started up. Dev i ce : MC X Program XXXXXXX Version: 1.3 Main menu Initialisation of remote control unit BB-3 is complete. One of the four main menu items can be selected using the given keys.

Parameter group C 4. Parameter group D 1. currents 2. time ramps or Change to an alternative set of parameter groups. (Depending on the MC software there can be up to 3 sets, each with 8 parameter groups.) Depending on how the MC microcontroller is programmed, a password (? : ) may be requested on the display when changing over to an alternative parameter group. Only when the correct password is entered can another parameter group be accessed. Select parameter group 1 to 8 Change from parameter groups to parameter groups Change from parameter groups to parameter groups Return to main menu Activate storage menu (see section 6) 3.1 Select parameter (Keys 1...8) Keys are used to exit the submenu config/cal into the relevant submenu select parameter Select a parameter 1.

The following text may for example be displayed: 1 I ma x P ump ± 2mA 1230 Keys for entering parameter: Edit functions Enter number Delete number left of cursor Move cursor to left or right Increase or decrease number by the given "+/-" value in steps. The new value is accepted instantaneously by the MC without Enter 1 ) Accept instantaneously in MC 1 ) Abort function and return to submenu Select parameter 1 ) Stored in EEPROM only by means of Storage menu If a value entered for a parameter lies outside the given value range, an error message will be output and the setting will not be accepted. General functions pressed + Load standard values from MC-EPROM Parameter types Different types of parameter are set in the MC software, and they offer various editing functions. Depending on the parameter type the following texts will be displayed: 1. Type "Numeric" : Parameter 3: No. of teeth Value range 0-510, Steps ±1 Actual value Line for error messages 3 No. o f t e e t h 0-510± Editing and general functions Brueninghaus Hydromatik 4/12 BB-3

Type "Potentiometer calibration" To enter parameter type potentiometer calibration a program routine in the MC electronics is initiated, that reads in the actual value at an analogue input and displays it on the BB-3 as an input voltage. The minimum voltage U min of a particular potentiometer setting is accepted as the 1st parameter by the ENTER command. With the next setting of the potentiometer the maximum voltage U max is accepted as the 2nd parameter via ENTER command. : Parameter 2: Travel lever 2.Travel lever Maximum/Minimum setting Mi n imum set t i ng Actual voltage 0.0 V Error message Acceptance of new value Abort function and return to submenu Select parameter 5. Type "Learning curve" With this parameter type the MC electronics stores the relationship between two input signals, for example as a characteristic of the relationship between Diesel engine speed and position of the injection pump in the unloaded condition. The input values must be changed slowly, e.g. by increasing the engine speed. Press ENTER to confirm completion. : Parameter 3: Recording of a Learning curve Actual frequency (proportional to engine speed) Voltage at potentiometer 3 L e a r n i n g c u r v e 900 Hz 0.3 V Input completed Abort function and return to submenu Select parameter BB-3 5/12 Brueninghaus Hydromatik

Depending on the application program (notes are contained in the respective software description) the machine has to be brought into a "safe condition" for data storage (for example neutral position of the lever). Storage of data is carried out automatically during "safe condition". Brueninghaus Hydromatik 8/12 BB-3

This means that the values of all parameters will be retained even if the supply voltage is switched off. Teach? - - > < EN T E R > Cance l? - - > <MENU> Store parameters Abort 6.2 Default Params (Key 2) With this function all parameters can be reset to the standard values fixed in the EEPROM of the MC electronics. At the same time these standard values are also stored in the EEPROM De f au l t s? - - > < EN T E R > Cance l? - - > <MENU> Load default values Abort 6.3 Get EEPROM (Key 3) When this menu item is activated all parameters are transmitted from MC-EEPROM and loaded into the selected area of the BB-3. N.B.: Names may be displayed as well as question marks. Ge t i n Memo r y? 1:Name 2:?????????????? 3:?????????????? This permits e.g. an optimum control setting to be stored in the BB-3 and if required to be transmitted to another system of the same type, thus considerably shortening control setting times. Control panel BB-3 can store a max. of 3 parameter sets. The data in the BB-3 will be retained, even if the BB-3 is separated from the MC. 1 3 Select store area eturn to Storage After selecting the area the following message will be displayed: The MC transmits the data, the progress being displayed as a percentage. Please wait! Loading... XX% The BB-3 will then request a name for the store area. The name can have a maximum of 12 characters. Name? 1: BB-3 9/12 Brueninghaus Hydromatik
