Input Chattering Elimination Function (AI/R)
A bounce delay is provided on the AI/R input to eliminate erroneous operation caused by input bounce (chat-
tering).
tON
AI/R
(Active Low)
tON < 62.5ms: input is ignored.
62.5 ≤ tON ≤ 125ms: indeterminate
tON > 125ms: input is accepted.
Input Control Functions
When AI/R is open circuit, a 256Hz signal is output.
When AI/R is HIGH or LOW, it selects the alarm (HIGH)/reset (LOW) function or reset (HIGH)/alarm (LOW)
function depending on the version.
