If the switching condition
MAX
is selected in the scroll list
func
:
• Enter the upper limit.
• Press ENTER.
The alarm will switch if the measured value exceeds the limit.
If the switching condition
MIN
is selected in the scroll list
func
:
• Enter the lower limit.
• Press ENTER.
The alarm will switch if the measured value falls below the limit.
If the switching condition
QUANT.
is selected in the scroll list
func
, the limit of the output has to be defined:
• Enter the limit of the totalizer.
• Press ENTER.
The alarm will switch when the measured value reaches the limit.
A positive limit will be compared to the totalizer value for the positive flow direction.
A negative limit will be compared to the totalizer value for the negative flow direction.
The comparison will also take place if the totalizer of the other flow direction is displayed.
R1 Input\Function: MAX\High Limit
R1 Input\Function: MIN\Low Limit
Example
High Limit
: -10 kg/h
mass flow rate = -9.9 kg/h
the limit is exceeded, the alarm switches
mass flow rate = -11 kg/h
the limit is not exceeded, the alarm does not switch
Example
Low Limit
: -10 kg/h
mass flow rate = -11 kg/h
the measured value is below the limit, the alarm switches
mass flow rate = -9.9 kg/h
the measured value is not below the limit, the alarm does not switch
R1 Input\Function: QUANT.\Quantity Limit
Notice!
The unit of measurement of the limit is set according to the unit of measurement of the selected physical quantity.
If the unit of measurement of the physical quantity is changed, the limit has to be converted and entered again.
Example
physical quantity: mass flow rate in kg/h
Quantity Limit
: 1 kg
