Activation signal comes from a digital input or "a virtual digital input" such as a Time channel. The Timer
counts down from falling edge.
Pos. Description
1 Remaining time
2 Activation
3 Duration
4 OUT
5 Time
The below parameters will set the Timer active when
Digital Input 1 on Slot A is closed and keep it active
for 30 s after it is opened.
Duration: 30 s
Timer: DigIn SlotA.1
A duration of 0 seconds can be used for
simply overriding a Time channel activated
from a digital input without any off delay
after the falling edge.
Example
Problem:
We have an AC drive for air conditioning in a
warehouse. It needs to run between 7 am - 5 pm on
weekdays and 9 am - 1 pm on weekends.
Additionally, we need to be able to manually force the
drive to run outside working hours if there are people
in the building and to leave it running for 30 min
afterwards.
Solution:
We need to set up two intervals, one for weekdays
and one for weekends. A Timer is also needed for
activation outside the office hours. An example of
configuration below.
Interval 1:
P3.12.1.1: ON Time: 07:00:00
P3.12.1.2: OFF Time: 17:00:00
P3.12.1.3: Days: Monday, Tuesday, Wednesday,
Thursday, Friday
P3.12.1.4: Assign to channel: Time channel 1
