If the acceleration exceeds the limit value plus hysteresis again, the alarm output is reset.
Enter the hysteresis in input field Hysteresis.
>= Acceleration limit value + Latch
The characteristic of the switch is increasing. The condition for the output is met when the
acceleration reaches the defined limit value Value 1. The alarm state is latched.
If the acceleration falls below the limit value again, reset the alarm by a reset latch
command either through the digital input Reset latch (see
configuration software (Monitor → Reset latch).
<= Acceleration limit value + Latch
The characteristic of the switch is decreasing. The condition for the output is met when
the acceleration falls below the defined limit value Value 1. The alarm state is latched.
If the acceleration exceeds the limit value again, reset the alarm by a reset latch command
either through the digital input Reset latch (see
configuration software (Monitor → Reset latch).
Acceleration outside window
Define with limit value Value 1 and limit value Value 2 a limit window. The function output
is set when the acceleration leaves the window. See
Figure 5-46: Diagram limit monitoring Acceleration outside window
A. Alarm activated
B. No alarm
C. Value 2
D. Value 1
E. Hysteresis
The function output is in initial state (no alarm) as long as the measuring value is outside
the limits by considering the hysteresis values.
Depending on the selected function, input fields Value 1, Value 2 and Hysteresis are
enabled.
