5.3 Hints for several repair duties
Replacement of the I/O-module – the replacement of the I/O-module does
not require any adaption duties.
Replacement of the position actor – after replacement, the setting of the
needle zero position is required.
Replacement of control board KK66 – procedure: demount rear cover, pull
off four cable connectors to the control board, loosen both fixing screws, pull
off control board from the motor. Be aware to avoid damage to the electronical
components; put the control board into a bag protecting it from electro-statical
load and avoid any contact to metal things. After replacing the control board,
all setup data and the sewing programs must be loaded into the machine.
Replacement of the front box – this is the statical element of the connec-
tion control box and of the foot pedal; each transmission element of the pedal
is calibrated; since that, the front box should only be replaced as a whole.
Replacement of the motor – this is fixed with four screws in the motor
housing; the control board must be removed before it can be demounted.
Loading of new software – future developments can be loaded into the
control by replacing an EPROM; to replace the EPROM, remove rear cover,
replace EPROM (mounted on a frame in the upper left corner); when inserting
the new EPROM be sure to insert all pins and bend none.
