The user must observe all instructions and warning notices contained in these operating instructions in order to maintain this condition and guarantee safe operation. Any other use or use exceeding that specified, e. [. . . ] - 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. parallel runs must definitely be avoided. ) - 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. There are three ways of attaching the motor to the sewing machine 1. 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. Modifications at this level must only be done by service staff. The full activation period is set with parameter t 03 51 and the holding force during partial activation with CAUTION A holding force that is set too high may lead to damage to the magnets and the control unit. Make absolutely sure that the magnets have a reliable power on period (ED) and set a suitable duty cycle for it in accordance with the table below. Effect low holding force high holding force (full activation) When pushing the pedal forward, with a raised sewing foot the start up delay, which can be set with parameter t 03 10, comes into force. Moving angle of rotation Waiting time up to the turning back The turning back function runs after the cutting procedure. 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. [. . . ] the thread is cut after the stuffing program finishes if the thread trimmer is active. If the number of segments set by button D is 0, the stuffing program runs until pedal setting -2 ends the program. Reducing speed when shifting the feed dog Wished speed reduction when shifting the feed dog. If parameter t 00 35 has been selected, one stitch before the backtack magnet is turned on and off, the backtack speed is switched to the backtack synchronization speed. [. . . ]
