ATR444 Timer Function

[heatologist]

I have a ATR444-14ABC-T controller with RS485.

I am looking to implement a timer delay on function with the following configuration:
c.ou.1 <- c.Val
d.i.2.F <-t.1.Sta.
AL.3.f. <- tMr.1

Questions:

Is this all that is required set up an on-delay timer function, closing terminals 12-13?

How is the time reset? Opening of DI2 (terminals 19-24)? Does any other function reset the time - for examples, change of start stop status?

Thanks

I should add that I do not have the controller in my shop to experiment...

Hi,

First of all, you need to enable the Timer 1 function by setting Par. 420 to "ENAb.".

d.i.2.F <-t.1.Sta.
Then, you need to configure the digital input 2 on Par.. 284, which we will activate from terminals 19 and 24. If you want to simply start the timer, you enable it in "t.1.Sta." However, if you want to have a start/stop functionality for the timer, you should enable it in "t.1.S.E."

In the Alarm 3 group, set Par. 173, to tMr.1.
By doing this, every time you close terminals 19 and 24, you activate the digital input 2, which starts the timer. The associated alarm will trigger and stay active for as long as the timer is running.
