Limits (function 51)

Figure 6-26
The device monitors up to four limits for every component, and these limits can be allocated
to any measuring range. Each limit can be allocated to any relay using function 71.
You can only parameterize positive limits up to 100%.
"Alarms at decrease signal":
Here you select whether a limit alarm is to be switched if the entered limit is exceeded or
fallen short of.
"Applies to 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 numbers and
indicate the ranges in which the limit monitor is to be active. In the above example, this is
measuring range 3.
"Limit alarm":
The limit monitoring of every single limit can be switched off individually using 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 using the fifth softkey (
