SLD1 compare mode = In1=In2
Turn on condition Absolute value of (Input 1 - Input 2) <= SLD1
sensitivity
Turn on delay time Turn on condition must remain valid for SLD1 pick up
delay. After the delay SLD1 status = True.
Turn off condition Absolute value of (Input 1 - Input 2) > (SLD1
sensitivity + SLD1 hysteresis)
Turn off delay time Turn off condition must remain valid for SLD1 drop
out delay. After the delay SLD1 status = False.
SLD1 compare mode = In1-In2>Sen one shot
Turn on condition (Input 1 - Input 2) > SLD1 sensitivity
Turn on delay time After the turn on condition is met a timer begins. The
turn on condition does not need to rem ain valid while
the timer runs.
After SLD1 pick up delay expires SLD1 status = True.
Turn off condition After SLD1 status goes True a timer begins.
After SLD1 drop out delay expires SLD1 status =
False.
The minimum time SLD1 status is True is
approximately 1 millisecond.
Reset condition SLD 1 becomes active again when (Input 1 - Input 2)
<= (SLD1 sensitivity - SLD1 hysteresis)
SLD1 compare mode = In1-In2<Sen one shot
Turn on condition (Input 1 - Input 2) < SLD1 sensitivity
Turn on delay time After the turn on condition is met a timer begi ns. The
turn on condition does not need to rem ain valid while
the timer runs.
After SLD1 pick up delay expires SLD1 status = True.
Turn off condition After SLD1 status goes True a timer begins.
After SLD1 drop out delay expires SLD1 status =
False.
The minimum time SLD1 status is True is
approximately 1 millisecond.
Reset condition SLD 1 becomes active again when (Input 1 - Input 2)
>= (SLD1 sensitivity + SLD1 hysteresis)
