Principle of LED/relay output operation for one threshold mode

Parameter  

“SEtP”  

sets   a  

threshold

  of   the   relay,   and   parameter

  “HYSt”

  sets   a

hysteresis

  of     the   relay   (

6.12a

).   The   relay   can   change   his   state  

only

  when   input   value

exceeds (over or under)  

border value

  and  t

(

) are bigger than the time

  and

.

 

Border values

  means   values   equal

threshold

hysteresis

 and

hysteresis

 

respectively. 

If  

“t on”

  and  

“toFF”  

parameters

 

are set to “

0

”, then the relay state will be changed

as

      soon

 

 

 as input value exceeds any of the 

border values

 (see points  A and C, 

6.12

 

a, b, c

).

If   values of  

“t on”

 or/and  

“toFF”

 are positive, then relay state will be turned on if the

input value exceeds the 

border values

 and stay bigger (or lower) during at least 

“t on”

 (see

points  B

, D

ON

, 

6.12 a, d, e

). Similarly, the relay will be turned off if  time 

“toFF” 

elapse since

the input signal value exceeds any of the 

border values

 (see points  B

, the relay will not change his state (see points  A and C,

The state of relay output while the input value exceeds the

 (points A, B,
