Absolute: check
Value at error: >Off< or >On< or >Hold Value<
Delay: manual input
Hold: manual input
•
>Limit contact level<
If the entered upper level limit value is exceeded, a digital signal is output. If the value
falls below the lower level limit, this digital signal is reset = hysteresis function to avoid
output jitter.
Selection/Input Options:
Logic: >Normally open< or >Normally closed<
Threshold on: manual input
Threshold off: manual input
Absolute: check
Value at error: >Off< or >On< or >Hold Value<
Delay: manual input
Hold: manual input
•
>Limit contact velocity<
If the entered upper velocity limit value is exceeded, a digital signal is output. If the
value falls below the lower velocity limit, this digital signal is reset = hysteresis func-
tion to avoid output jitter. The calculated mean flow velocity is used (also calculated
from several paths). Not possible with the combined measurement point.
Selection/Input Options:
Logic: >Normally open< or >Normally closed<
Threshold on: manual input
Threshold off: manual input
Absolute: check
Value at error: >Off< or >On< or >Hold Value<
Delay: manual input
Hold: manual input
•
>Limit contact water temp.<
If the entered upper water temperature limit value is exceeded, a digital signal is out-
put. If the value falls below the lower water temperature limit value, this digital signal
is reset = hysteresis function to avoid output jitter.
Selection/Input Options:
Logic: >Normally open< or >Normally closed<
Threshold on: manual input
Threshold off: manual input
Absolute: check
Value at error: >Off< or >On< or >Hold Value<
Delay: manual input
Hold: manual input
•
>Limit contact air temp.<
If the entered upper air temperature limit value is exceeded, a digital signal is output.
If the value falls below the lower air temperature limit value, this digital signal is reset
= hysteresis function to avoid output jitter.
Selection/Input Options:
Logic: >Normally open< or >Normally closed<
Threshold on: manual input
Threshold off: manual input
Absolute: check
Value at error: >Off< or >On< or >Hold Value<
Delay: manual input
Hold: manual input
