Description
As a convenience feature of the windshield wiper intermittent and
wipe/wash operation
are implemented in most of the automobiles. The U**1B is the
low-cost solution for an
accurate timing function control. Wipe/wash mode has priority over
interval mode.
Interval pause and afterwiping 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 U**1B.
