2.4.4. Timer (Can be set individually for Out1 and Out2)

The Timer allows the user to introduce different timer functions by editing the 3 timer parameters:

• Timer mode

• Timer scale
• Timer value
2.4.4.1. Timer mode
Selects which type of timer function is introduced on the Switching Output. Any one of the following
is possible:
2.4.4.1.1. Disabled
This option disables the timer function no matter how timer scale and timer delay is setup.
2.4.4.1.2. Turn On delay (T-on)
The activation of the switching output is generated after the actual sensor actuation like shown in
figure below.
