Additional Features
The SVI II ESD acquires actuator pressures, valve position, air supply, and set-point whether
the safety function is invoked or not. The SVI II ESD captures and stores data when the safety
function is invoked. The result is an automatically saved as a signature in the non-volatile
memory.
The SVI II ESD is capable of annunciating faults resulting from a PST or using data acquired
from internal diagnostic tests. SVI II ESD internal diagnostics diagnose the following:
I/P health
Relay health
Sensor health (A/D, Temp, Pressure, Air supply, etc.)
Other features:
Discrete output (SW #1) is de-energized for any fault related to the I/P, relay, or valve/
actuation assembly, resulting from a PST or while in normal operation.
HART
®
communication (HART
®
CMD#48) can be used as the basis for fault
communication.
Blinking alarms on the local display alert users to fault conditions.
For all fault conditions the ESD device attempts to remain in the energized state unless
an ESD command is given. On the
Pneumatics and Electronics tab on the Status screen
of the ESDVue software you can set whether pneumatics, actuator, or electronics
testing fail to a predefined high or low level.
