Wipe-Wash interval relay, interval time 3...20s programmable during use

The wipe-wash interval mode is programmed using one of the switches S3 or S2b. Both switches must be OFF for programming! If one of the switches is pressed only briefly (<1sec), the programming mode is activated. If now the interval switch or S3 is switched on within 20sec. (>1sec), the elapsed time is the interval time. By default, the interval time is 3sec. Washing function: A dry protection wiping function leaves the windscreen wiper 0.5sec. start delayed. S3 becomes shorter than 1sec. actuated only 1 wiping process. If S3 is actuated for longer than 1sec. the wiper runs continuously until S3 is released. After releasing S3, the wiper continues to run for approx. 4sec. and after about 8sec. wipes once.
