8.2 Configuring the limits
8.2.1 General information on setting the limits
The monitoring mode of the FireGuard 2 is defined by the settings of the limit function. The
following parameters can be monitored:

Turbidity limit

Limit for turbidity gradient (

Section 8.2.6)

Temperature limit

Limit for temperature gradient (

Section 8.2.6)
The following limits are set in the standard configuration:
Limit Source Limit Cut-in delay Cut-out delay Remarks
1 Turbidity 10.0 6 s 0 s Pre-alarm
2 Turb.Grad. 0.0 6 s 0 s Inactive
3 Temperature -30.0 6 s 0 s Inactive
4 Temp.Grad 0.0 6 s 0 s Inactive
5 Turbidity 30.0 8 s 0 s Main alarm
6 Turb.Grad. 0.0 8 s 0 s Inactive
7 Temperature -30.0 8 s 0 s Inactive
8 Temp.Grad 0.0 8 s 0 s Inactive
On the temperature limits, the value -30.0 indicates that the function is deactivated. On all
other limits, the value 0.0 indicates that the function is deactivated.
The following applies for limit monitoring:
CAUTION!
The limits used must be adjusted according to the local conditions.

Limits 1 .. 4 are intended for the lower limit level (pre-alarm) and are assigned to output
A1.

Limits 5 .. 8 are intended for the higher limit level (main alarm) and are assigned to out-
put A2.

In the standard setting, only the monitoring of the turbidity value is used.

In order for a pre-alarm to always be triggered first before a main alarm, the cut-in delay
of the main alarm must be greater than that of the pre-alarm.
The limits have to be configured according to Section 8.3so that they are not only dis-
played, but also output accordingly.
