1. General The MICROCONTROL controls of the DÜRKOPP ADLER 743-221 include the integrated comprehensive MULTITEST testing and monitoring system. A microcomputer assumes the control tasks, monitors the sewing process and signals operating faults and malfunctions. Special programs facilitate mechanical adjustments and make possible a rapid testing of the input and output elements without additional measuring apparatus. Errors and test results are shown in a 2 x 16 digit display.
2. Description of the Controls 2.
2.2 Operator Controls at the Controls The needle- and underthread monitors are activated with the DIP switch b417 at the controls. The dials b401 and b402 have no function. Caution Electric Current ! The switches may only be altered with the main switch turned off. ATTENTION ! The switches are only verified once after the sewing unit is turned on. After changing the switch setting turn the main switch off and on again or operate the " STOP " key.
2.3 Display The Microcontrol controls are equipped with a 2 x 16 digit display. It displays program number, sewing lengths, underthread reserve and piece counts. With operator errors or malfunctions the function sequence is interrupted and the cause shown by the corresponding error symbol. The operational readiness of the sewing unit is signaled by showing the current parameters in the display. The settings correspond to the last selected setting before being turned off.
3. Description of the Function Keys 3.1 Selecting and Adjusting the Seam Length Three stored seam lengths can be selected via the L1, L2 and L3 keys. A change in the seam length can only be made before starting the feed procedure. – Select the stored seam length by pressing the L1, L2 or L3 key. The selected seam length is shown in the right half of the first line of the display. – If "L?" appears in the display a seam length was selected under which no valid value is stored.
3.4 Setting Parameter Values The set parameter values / seam lengthsare changed via the " + " or " - " key. – Press the " + " key. The parameter value / seam lengthsis increased. – Press the " - " key. The parameter value / seam lengthsis decreased. – Only in program 41 ! Press the " + " and " - " keys at the same time. The initial value for the underthread reserve is reset to 0000.
3.8 Securing at the Seam End End securing at the seam end is selected by pressing this key. The end securing is only conducted if it is activated with the " – – " key. Press the key. Securing through stitch condensation is selected. The LED is lit. Press the key. Securing through seam bar tacking is selected. The LED is off. 3.9 Securing Activation The selected securing at the seam beginning or at the seam end is activated by pressing this key. – Press the key.
4. Setting the Sewing and Testing Programs The sewing and testing programs are selected with the " Program " selection switch. – Set the " Program " switch to the desired program. – " Turn the main switch on " or press the " STOP " key.

At the last program step the return to the 1st program step occurs by pressing the " Σ " key.
– Press the " Σ " key. Set the number of stitches for stitch condensation at the seam beginning. Setting range: 3 - 8 stitches Resolution: 1 stitch – Press the " Σ " key. Set the number of stitches for stitch condensation at the seam end. Setting range: 3 - 8 stitches Resolution: 1 stitch – Press the " Σ " key. Set the number of stitches for bar tacking at the seam beginning. Setting range: 3 - 5 stitches Resolution: 1 stitch – Press the " Σ " key.
4.4 Setting the Underthread Counter The underthread counter is set in program 41. The presetable decrementer monitors the underthread reserve. The decrementer works with the factor 10, this means, after every 10th stitch the preset value is decreased by 1. This is shown in the right half of the lower line of the display.
