GE Oil & Gas
 Operating: In this mode the SVI responds to the input signal
and positions the valve appropriately (indicator green).
 Manual: In this mode the valve does not respond to the input
signal. Instead it remains stable in one position which is the
position that the valve was when manual mode was entered
or a new position selected by the user (see Setpoint) (indicator
yellow).
 Configure: In this mode you can set configuration parameters
of the positioner or controller (indicator yellow).
 Calibrate: In this mode you can set calibration parameters of
the positioner (indicator yellow).
 Diagnostic: In this mode you can run response time tests, step
response tests, and positioner signatures (indicator yellow).
 Bumpless transfer: This is a transition mode when you select
operating mode from manual mode (see Bumpless Transfer)
(indicator red).
 Failsafe: When the SVI cannot operate correctly the device
goes to the failsafe position and remains in the failsafe mode
until the user intervenes (indicator red).
Status Code List
POSITION_ERROR The valve failed to go the requested position within the required time.
POSITION_SENSOR_ERROR The position sensor has failed or its connection is open.
PRESSURE_SENSOR_
ERROR
The pressure sensor has failed.
SIGNAL_SENSOR_ERROR The input signal measurement sensor has failed.
REFERENCE_VOLTAGE_ERR
OR, IP VOLTAGE ERROR
The primary reference voltages inside the SVI is incorrect and all
other measurements will likely be affected.
SYSTEM EEPROM FAULT The SVI cannot write to EEPROM. This prevents the SVI from function-
ing.
WATCHDOG TIMER TIME-
OUT
The watchdog timer was not reset by the SVI. This indicates a serious
failure in the SVI.
CIRCUIT TEMPERATURE
FAULT
he circuit board reached a temperature outside of its rated tempera-
ture.
BIAS_OUT_OF_RANGE The signal to the I/P which causes no valve movement (called the
bias) has changed and is outside of the normal operating range.
SELF_CHECK_FAILURE On startup, the SVI did not pass a self check.
HART_ERROR An excessive number of HART transmission errors have occurred.
