Parameterizing a Switching Signal (SSCx)

Two independent switching signals (SSC) can be parameterized for each measured variable. 
The principle for parameterization is the same for each measured variable (SSC).

The figure below illustrates the relationships:

Figure 7.2

For example, the SCC1.1 switching signal can be used to monitor the vibration velocity "Veloc-
ity RMS." Two independent measured value limits (SP1 and SP2) can be set for monitoring a 
measurement range. This mode can also be used to switch between monitoring a measure-
ment range and monitoring an individual point. You can use "Off Delay" to set a delay time for 
how long the measured value limit can be minimally exceeded before the switching signal 
responds. This is done to prevent the SSCx switching signal from switching back and forth.

This concept is implemented for each SSCx. The appropriate parameters are available and can 
be set independently of each other.
