The user must observe all instructions and warning notices contained in these operating instructions in order to maintain this condition and guarantee safe operation. Use for the intended purpose includes observing the manufacturer's prescribed conditions for operating, maintenance and repair. The DACbasic or DACclassic will only work safely and reliably if the control unit is used in accordance with these operating instructions and its intended use. [. . . ] Braided, large cross-section wires must be used between moving parts and the housing and the earth connection must be kept as short as possible. - Signal transfer By using electrostatic and magnetic shielding, twisted wires and the cable run you must ensure that no interference voltage is transferred from the control and main current cables to signal cables. (A right angle cable crossover is better than one with a smaller angle. ) - Separating equipment parts Equipment parts susceptible to interference (components with pulse processing and/or with low levels) should be separated and/or shielded from switch equipment such as electromagnetic relays, thyristors etc. - In spite of the fact that it is not susceptible to interference, the DAC basic or DACclassic must not be operated in the immediate vicinity of HF welding machines or similar equipment in order to avoid any malfunctions. Installing in the top of the sewing machine There are three different ways of transferring the drive torque from the motor to the machine Options: - Tooth belts and toothed belt discs - V belts and V belt discs - direct axial connection of the motor to the machine's main shaft When using toothed belts the torque is transferred from the motor to the machine without slippage. When using V belts the torque is not transferred from the motor to the machine without slippage.

Access rights to the technician's level The technician's level must not be accessed by normal users. The technician's level is unlocked by the following key combination: When switching on the control unit P (23)and the reset (18) button must be pressed at the same time. P Min Max 1 Unit Description Blocking the initial interlock keys 0 = released; 1 = blocked Blocking the end interlock keys 0 = released; 1 = blocked Blocking thread keys 0 = released; 1 = blocked Blocking stitch programme keys 0 = released; 1 = blocked Blocking programming keys 0 = released; 1 = blocked Before commissioning the control unit the following must be ensured, checked or set: The correct assembly of the drive, position sensor and any accessories used If necessary the correct setting of the motor rotation direction with parameter t 08 05 The correct sewing machine-compatible maximum speed with parameter t 08 00 The position settings The settings of the remaining relevant parameters Save the set values P Min Max Unit Description Display software version Display control unit serial number Display machine serial number Display production date of the upper part of the machine Showing machine class and ­sub class P Min Max 4 Unit Description Loading parameters 0 = Nothing; 1 = Sewing data from DA dongle; 2 = Sewing data from the back up area; 3 = Seam runs from DA dongle; 4 = Master Reset Saving parameters 0 = Nothing; 1 = Sewing data on the DA dongle; 2 = Sewing data in the back up area; 3 = Seam runs on the DA dongle 51 10 0 When the dongle is being accessed parameter t 51 10/11 = 1 or 3 the red message LED flashes. When the stop position is reached the drive stops for the duration of the reverse rotation power on delay ( parameter t 12 02). Then it turns back at positioning speed at the angle set by parameter t 12 01. The keys are called smart keys which means that the different functionalities can be applied directly to these keys. These are programmed using the P key on the OP1000 followed by pressing the corresponding key for about 2 seconds. The key is called a smart key which means that various functionalities can be applied directly to this key. This is programmed using the P key followed by pressing the F key for about 2 seconds. Description Setting the input function for the OP1000 "F" key 0 = no function; 1 = on threading help; 2 = Bartack suppression/recall; 3 = Manual bartack; 4 = Half stitch; 5 = Full stitch; 6 = Direction finder position; 7 = Turning back 8 = Input function module 1; 9 = Input function module 2; 10 = Input function module 3; 11 = Switch high lift for walking foot; 12 = Ornamental Backtack; The keys are called smart keys which means that the different functionalities can be applied directly to these keys.

Cut off speed P Min Max 750 Unit rpm Description Cut off speed The thread cutting signal is switched on when the cutting speed is reached with parameter t 02 10 and switched off when the set angle value parameter t 02 11 has been reached. A time lag for repeatedly switching on the FA magnets can be set using parameter t 02 20 . [. . . ] The first incoming "needle down" position is then always considered stitch 0 if the function is started outside the "needle down" position. Counting and switching the reverse feed lever off are synchronised at the "needle down" position. At full speed the end backtack is only switched on when speed n is reached ( parameter t 00 36) and synchronisation is switched on at the "needle down" position. (Switchover of forward backward at the bartack) Pre-control angle when turning the backtack magnet off. [. . . ]
