10(19)
Online alarm low limit for circuit board temperature. Tem-
perature measurement has to be below this limit value for a
time indicated by Device temperature latch time.
Device temperature hi alarm limit
Online alarm high limit for circuit board temperature. Tem-
perature measurement has to be above this limit value for
a time indicated by Device temperature latch time.
Device temperature latch time
Online alarm activation time for temperature.
Communication fail rate alarm limit
Alarm limit for fieldbus communication failure.
Total operation time warning limit
Warning limit for total operation time.
3.1.3 Input
3.1.3.1 Input value
Direction
Direction of positioner. Options are
• Rising (increasing of setpoint input results in opening of
the valve)
• Falling (increasing of setpoint input results in closing of
the valve)
Lower Value
Defines the operational lower range value of the input value
(0%) in engineering units.
Upper Value
Defines the operational upper range value of the input
value (100%) in engineering units.
Unit (Input)
The engineering unit of the input value.
ND9000 supports signal cutoff and limiting in both ends of
the operating range. The configuration parameters are;
Low cutoff, Low limit, High cutoff and High limit.
• If the input signal is smaller than low cutoff, the valve
will be fully closed.
• If the input signal is smaller than low limit, the valve
stays in the low limit.
• If the input signal is greater than high cutoff, the valve
will be fully opened.
• If the input signal is greater than high limit, the valve
stays in the high limit.
The cutoff overrides the limit as follows;
• If the low cutoff > low limit, the low limit is not active.
• If the low cutoff < low limit, both low cutoff and limit are
active.
• If the low cutoff is set to zero, the low cutoff is not ac-
tive.
• If the high cutoff < high limit, the high limit is not active.
• If the high cutoff > high limit, both high cutoff and limit
are active.
• If the high cutoff is set to 100%, the high cutoff is not
active.
3.1.3.2 Working Range
Lower Value
Lower Value (Output Signal Range): Lower range value of
the process variable (0%) in engineering units.
Upper Value
Upper Value (Output Signal Range): Upper range value of
the process variable (100%) in engineering units.
Unit (Output)
The engineering unit that the output value is reported in.
3.1.3.3 Travel Time
Travel Time CLOSE
Setpoint for the time in seconds between the change of the
state from OPEN to CLOSED.
Travel Time OPEN
Setpoint for the time in seconds between the change of the
state from CLOSED to OPEN.
3.1.4 Human Interface
3.1.4.1 Maintenance
Calibration Date
Date of last calibration of the device.
Configuration Date
Date of last configuration of the device.
Maintenance Date
Date of last valve maintenance.
3.1.4.2 Simulation
Simulation
Enable or disable the simulation function.
Simulation Value
For commissioning and maintenance reasons, it is possible
to simulate the Readback by defining the value and the
status. This means that the Transducer Block and the
Function Block will be disconnected.
Quality
Signal quality information.
Limit
Signal limit information.
3.1.5 Certificates and Approvals
Device Certification
