Connection details
Performance check
l
When the intermittent input (Ter. D) goes high,
Ter. A should get connected to Ter. B for one wipe
cycle ( The unit assumes the wipe cycle is
completed when Ter. C goes to GND from VCC
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. A and B get connected
for one wipe cycle. This cycle continuous until Ter.
D is high.
l
When wash input (J) becomes active output Ter.
A should get connected to terminal B after 0.7
sec. and when Ter. J goes low Ter. A get disconnect
from Ter. B after 2 sec. The wash should have
higher priority than the intermittent signal.
l
When the Ter. H is low the wash function should
be ignored.
