Function diagram Description
Delay On (NOTC). After the relay is energized,
a countdown (T) is started. During the count-
down, relay contacts 15-16 (25-26) remain
closed and contacts 15-18 (25-28) remain open
(relay is off). Once the countdown is nished,
contacts 15-16 (25-26) open, and contacts
15-18 (25-28) close (relay is on), remaining in
this state until the relay is de-energized.
Delay Off. After the relay is energized, contacts
15-16 (25-26) open, contacts 15-18 (25-28)
close, and a countdown (T) is started. Once the
countdown is nished, contacts 15-18 (25-28)
open, contacts 15-16 (25-26) close and remain
closed until the relay is de-energized.
Recycle (NO) After the relay is energized, a
countdown (T) is started. During the count-
down, relay contacts 15-16 (25-26) remain
closed and contacts 15-18 (25-28) remain open.
Once the countdown is nished, contacts 15-16
(25-26) open, and contacts 15-18 (25-28) close
for the period of (T); the cycle repeats as long
as the relay is energized.
Recycle (NC) After relay is energized, contacts
15-16 (25-26) open, contacts 15-18 (25-28)
close, and a countdown (T) is started. Once the
countdown is nished, contacts 15-18 (25-28)
open, and contacts 15-16 (25-26) close for the
period of (T); the cycle repeats as long as the
relay is energized.
