Kolver 032000 Operational Manual page 91

Starting from the preset threshold torque (see point 27) the system will start counting the degrees
and when the preset angle is reached the screwdriver will stop. If the preset angle is reached the
screw will be considered as correctly tightened, the green led will light up and the message
"tightening OK" will be displayed on the status bar. If the screwdriver stops before reaching the
preset angle the tightening will be considered not ok, the red led will light up and the message "error
angle not reached" will be displayed on the status bar. Therefore it's very important to set a torque
value (line 4) which is sufficiently higher than the threshold value (line 27), so that the set value is
reached before the screwdriver stops because of the reached torque.
 ANGLE/INPUT (A/IN): The threshold can't be set by the operator: in fact the value is the result of
an external impulse through a proper contact (see paragraph "connections").
This function can be very useful if the operator wants the screw to rotate a certain number of
degrees after reaching a position indicated by a precision instrument.
 ANGLE/LEVER (A/LV): the threshold torque value can't be set by the operator and the angle value
that appears on the display corresponds to the angle that is carried out starting from the moment in
which the lever is pressed.
