DIAGNOSIS
VPT10-H has several diagnostics in order to assist the predictive maintenance of the transmitter, minimizing the
problems in the process. By setting the parameters according to the specific application, user can count on a series of
indicators that will assist in the decision to execute the necessary system maintenance.
In addition, it also offers sensor and measurement status to alarm user for system abnormal behavior. These alarms
indicate faults common to HART
®
or pressure transmitter specific equipment, as described below.

COMMON ALARMS
PV OUT OF LIMITS: primary variable value is outside normal range.
NON-PV OUT OF LIMITS: a variable other than primary variable has its value outside normal range. For VPT10-H this
variable is the temperature and its limits are -40 °C and 85 °C.
LOOP CURRENT SATURATED: the output current value is saturated, above or below limits.
LOOP CURRENT FIXED: output current in fixed mode.
MORE STATUS AVAILABLE: indicates that device-specific alarms are active.
COLD START: there was a restart of the device.
CONFIGURATION CHANGED: some parameter of the device has been configured.
DEVICE MALFUNCTION: some important transmitter variable is malfunctioning.
VPT10-H SPECIFIC ALARMS
In the event of these alarms, the diagnostics alert icon and the message "-E-" will be displayed on the LCD display.
Figure 3.13 – Indication of specific error on VPT10-H.
INCOMPATIBLE SENSOR: the pressure sensor connected to the transmitter is not compatible with models supported
by the VPT10-H.
SENSOR NOT CONNECTED: the pressure sensor is not properly connected to the transmitter. Check the polarity of
the connector or if it is not damaged.
SENSOR NOT INITIALIZED: the pressure sensor is not correctly initialized to factory settings, which will inevitably
result in incorrect process measurements.
