Use a contact with good contact relia-
bility for the input. Contact bounce can
lead to erroneous operation of the
timer, so use a contact with short
bounce time. Make the resistance
between terminals for a short circuit
less than 1k-ohms. Make the resis-
tance between terminals for an open
circuit greater than 100k-ohms.
Be sure to use a photo-
coupler for non-contact
input.
Check that Vce = 0.6V
Max. when ON.
