FUNCTIONAL DESCRIPTION
As a convenience feature of the windshield wiper, intermittent and wipe/wash
operation functions are implemented in most of the automobiles. The IK642B is a cost-
effective solution for an accurate timing function control. Wipe/wash mode has priority over
interval mode. Interval pause and after-wiping time can be set to fixed values by using
resistors in a broad time range. Added value can be provided with an individual,
continuous adjustment of the interval pause by a potentiometer which may be built into the
stalk. For proper operation, it is mandatory to feed the signal of the wiper motor's park
switch into IK642B.
