PERFORMANCE CHECK

•

When the intermittent input (Ter. D) goes high,Ter.

Ashould get connected to Ter.B for one wipe cycle

(The unit assumes the wipe cycle is completed

when Ter.C goes to GND fromVCC level). Then for

time ‘t’ seconds ( the time should vary from 2 to

15 second with the resister R varying from 0 to 64

K) .Ter. A and B should be disconnected. Again

Ter.Aand B get connected for one wipe cycle. This

cycle continues as long as Ter.D is high.

•

When wash input (J) becomes active, output Ter. A

should get connected to terminal B after 0.7 sec.

(delay provided for water to reach from the nozzle

to glass) and when Ter. J goes low Ter. A gets

disconnected from Ter. B after 2 sec. The wash

should have higher priority than the intermittent

signal.
