"Gated SR-FF" function
The function is designed (to: e.g. function) as a filling or emptying function using only two intercon-
nected sensors

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
This 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 the timer scale and timer delay is set up.
2.4.4.1.2. Turn On delay (T-on)
The activation of the switching output is generated after the actual sensor actuation as shown in
the figure below.
