Reference Voltage Shutdown—When enabled,
the instrument shuts down whenever there is a failure
associated with the internal voltage reference. Default
is not enabled.
Sensor Alerts (1-2-3-2)
Travel Sensor Shutdown—When enabled, the
instrument shuts down whenever there is a failure
associated with the travel sensor. Default is not
enabled.
Temp Sensor Shutdown—When enabled, the
instrument shuts down whenever there is a failure
associated with the temperature sensor. Default is not
enabled.
Pressure Sensor Shutdown—When enabled,
the instrument shuts down whenever there is a failure
associated with the pressure sensor. Default is not
enabled.
Environment Alerts (1-2-3-3)
Auxiliary Terminal Alert (1-2-3-3-1)
Auxiliary Terminal Alert Enable—Yes or No.
When enabled, the auxiliary terminal acts as an alert
activation.
Auxiliary Input—The auxiliary input of the digital
valve controller can be configured to be used in
different ways. The default configuration allows a
pre-configured partial stroke test to be initiated by
shorting the aux terminals together, such as with the
use of an appropriately connected local pushbutton
switch. It can also be configured to enable an alert that
will be generated when a switch connected to the Aux
terminals is either “open” or “closed”. The third
configuration option is for the Aux terminals to be used
with the LCP100. In this configuration, the partial
stroke test is initiated using the LCP100, and the Aux
Input alert is not available.
Auxiliary Terminal Action— Can be Disabled,
Alert on Open or Close Contact, SIS Local Control
Panel or Push Button Partial Stroke Test. If the
LCP100 is not selected, the default is Partial Stroke
Test. If the LCP100 is selected during Setup Wizard or
enabled in Detailed Setup as Auxiliary Terminal Action
− SIS Local Control Panel, the following parameters
will be automatically set under Travel Alerts:
Hi Hi / Lo Lo Enable − YES
Lo Lo Point (%) − 1
Hi Hi Point (%) − 99
DVC Power Up − Manual Reset
Supply Pressure Lo Alert (1-2-3-3-2)
Supply Pressure Lo Alert Enable—When
enabled, the instrument sends an alert when the
supply pressure falls below the supply pressure alert
point.
Supply—Displays the instrument supply pressure
in psi, bar, kPa, or kg/cm
2
.
Supply Pressure Lo Alert Point— When the
supply pressure falls below the supply pressure alert
point, the supply pressure alert is active. To disable
the supply pressure alert, set Supply Press Alert Point
to zero.
Loop Current Validation Enable—When
enabled, the instrument shuts down whenever there is
a failure associated with the measured loop current
being out-of-range.
Travel Alerts (1-2-3-4)
Travel—Travel displays the actual position of the
valve in percent (%) of calibrated travel.
Set Point—Travel Set Point is the input to the
characterization function.
Travel Alert DB—Travel Alert Deadband is the
travel, in percent (%) of ranged travel, required to
clear a travel alert, once it has been set. The
deadband applies to both Travel Alert Hi/Lo and Travel
Alert Hi Hi/Lo Lo. See figure 4-2.
Travel Deviation Alert (1-2-3-4-4)
If the difference between the travel target and the
actual target exceeds the Travel Deviation Alert Point
for more than the Travel Deviation Time, the Travel
Deviation Alert is set. It remains set until the difference
between the travel target and the actual travel is less
than the Travel Deviation Alert Point minus the Travel
Alert Deadband.
Travel Deviation Alert Enable—Select Yes or No.
When enabled, checks the difference between the
travel target and the actual travel.
Travel Deviation Alert Point—The alert point for
the difference, expressed in percent (%), between the
travel target and the actual travel. When the difference
exceeds the alert point for more than the Travel
Deviation Time, the Travel Deviation Alert is set.
Default value is 5%.
Travel Deviation Time—The time, in seconds,
that the travel deviation must exceed the Travel
Deviation Alert Point before the alert is set. Default
value is 10 seconds.
