Operating instructions, 07/2006, A5E00478463
You can parameterize values up to 100% for the effective interval, and values up to 300 s for
the time constants "ti" and "ta". By cleverly combining these three parameters, you can
realize a low display delay (90% of time) despite high noise suppression.
The effect on the set attenuation parameters can be observed in the bottom line. The "live"
measured value is displayed here.

Figure 5-30 Limits
The device monitors up to four limits for every medium, which you can allocate to any
measuring range. Every limit can be allocated to any relay with function 71.
You can only parameterize positive limits up to 100%.
"Switches in case of shortfall":
Here you select whether a limit alarm is to be switched if the entered limit is exceeded or
fallen short of.
"valid for measuring range...":
Here, you allocate the limit to the desired measuring range(s) by pressing the third softkey
several times. When you do so, the pointers move over the measuring range identity
numbers and indicate the measuring ranges in which the limit monitor is to be active. In the
above example, this is measuring range 3.
"Limit monitoring":
The limit monitoring of every single limit can be switched off individually via function 52.
The response of a limit relay is registered in the logbook (function 3). As soon as the cause
of the limit alarm has been eliminated, the limit relay is reset automatically.
You can change to the next limit with the fifth softkey (
"Limit…").
