With this function it is possible to set the duration of the intervention of two relays at the
programmed positions (see function F 42).
Let us suppose that, in their rest condition, relay 1 has been set with the NC status
(normally closed) and relay 2 has been set with NO status (normally open). In addition, let
us suppose the operator wants to program the following intervention positions:
RELAY
R1
IN THE POSITION 150.00
FOR 0.5 sec.
RELAY
R2
IN THE POSITION 300.00
FOR 2.0 sec.

Note.
The
key is used to select the desired relay (2 in our example).
The program has been completed and, in our example, the two relays act like measuring
length limits. In fact, relay 1 closes its contact for 0.5 seconds if the position passes from a
value higher than 150.00 to a lower value; relay 2, instead, closes its contact for 2 seconds
if the position passes from a value lower than 300.00 to a higher value.
Important:
Timed relay outputs work with the relay outputs in NO status (normally open)
in their rest condition. They close their contact for the programmed duration of the
intervention.
With function F 40, it is possible to program the relays status (NO or NC) in their rest
condition. Based on this programming, the generation of the intervention impulse will occur
as indicated below.
