The admissible limits for DIN approved probes:
v
Chapter 9.12 "Important information for the probes in Chapter 9.13 to Chapter 9.15" and
v
Chapter 9.14 "Probes for water and oil"
8.3.6 Limit value difference,
hysteresis
Limit value difference monitoring:
If the value of the temperature difference of the analog
input 1-2 is exceeded, the alarm relay output is
switched.
0 to
50 to 100
Hysteresis difference monitoring:
Difference between the switch-off and switch-on
threshold, e.g. for rising and falling differential values.
0 to
2 to 100
Important information:
If, for example, temperature differences arise as a result of the spatial arrangement of a dual probe, an alarm may be triggered
by the concurrency monitoring even though the temperature being monitored has not yet been exceeded.
In this case, the difference monitoring limit value can be adjusted accordingly.
8.3.7 Setting range min. (for-
merly ALHI)
This is the lower limit of the setting
range for the limit value.
This value may not be lower than the lower end of the
connected probe or unit signal measuring range. It may
also not be set higher than the setting for the
alarm
limit value.
-9999 to
-200 to limit value
°C
8.3.8 Setting range max. (for-
merly ALLO)
This is the upper limit of the setting
range for the limit value.
This value may not be greater than the higher end of
the connected probe or unit signal measuring range. It
may also not be set lower than the setting for the
alarm
limit value.
Limit value
to
850 to 9999 °C
