8.05.01 Functions of the switches and buttons
Switch1
is for changing between the RPM and number-of-buttonholes readings in the display.
When this switch is up, the RPM reading is displayed. The RPM can be altered using
buttons T3 ( + ) and T4 ( - ).
When this switch is down, the number of buttonholes sewn is displayed. The maximum
number which can be displayed is 65536.
By holding button T4 pressed and pressing T2 briefly this counter can be reset to zero.
To do so the buttons must be held for approx. 1 second.
Switch 2
Is for setting the countdown mechanism.
When the switch is up, the following reading appears in the display:
XXX YYY
XXX = the total number of buttonholes to be sewn.
YYY = the number of buttonholes still to be sewn.
By pressing button T2, the YYY reading ( buttonholes remaining ) is made to equal the XXX
reading (total buttonholes).
The range for the total number of buttonholes lies between 0 and 500.
A start is only possible when switch 2is down ( off ).
In normal operation, a renewed start of the machine is impossible when the number of
buttonholes remaining is 0 ( YYY = 000 ). The fault reading BOBBIN appears in the display.
After changing the bobbin, this disturbance can be removed by pressing button T2.
This returns the number of buttons remaining ( YYY ) to the same level as the number of
buttons to be sewn ( XXX ).

Switch3
serves to start and stop winding the bobbin.
When the switch is up, winding can take place as long as the foot pedal is pressed and one
cycle is not yet completed.
Switch4
switches between work cycles.
When the switch is up the machine carries out only one cycle.
When the switch is down the machine carries out two cycles.
8.05.02 Switching the countdown device on/off
When the machine is switched on, the countdown mechanism (parameter 620) can be
switched on and off by the operating personnel as follows:
●Press buttons T1 and T4 simultaneously.
●Press button T2.
●Press button T3 or T4.
I = countdown ON
II = countdown OFF
●Press buttons T1 and T4 simultaneously.
