Table 5.1 - FY301 Diagnostics without the Configurator
Diagnostic with Configurator
If the positioner is on and w ith the communication circuit and t he processing unit working, the
configurator can be used for diagnostic, in case of problems with the positioner. The configurator
should be connected to the positioner according to the wiring diagrams show on Section 1.
Error Messages
The error messages inform the diagnostic through the self diagnostic of errors and malfunctioning.
When the configurator is communicating with the positioner, the user is informed on any problem
found, through the self diagnostic. At the
FY301
positioner, the error messages always alternate with
the information on the top line of the configurator’s display. Table 5.2 lists the error messages and more
details on corrective action.
ERROR MESSAGES POTENTIAL SOURCE OF PROBLEM
PARITY ERROR - The line resistance is not according to the technical characteristics.
- Excessive noise or ripple.
- Low level signal.
- Interface damaged.
- Power supply or battery voltage of the configurator lower than 9 V.
OVERRUN ERROR
CHECK SUM ERROR
FRAMING ERROR
NO RESPONSE
- Positioner line resistance is not according to technical characteristics.
- Positioner not powered.
- Positioner not connected or damaged.
- Positioner configured in multidrop mode being accessed by ON LINE SINGLE UNIT.
- Positioner reversibly powered (polarity is reversed).
- Interface damaged.
- Power supply or battery voltage of the configurator lower than 9 V.
LINE BUSY - Other device using the line.
CMD NOT IMPLEMENTED - Software version not compatible between configurator and positioner.
DEVICE BUSY - Positioner carrying out an important task, e.g., local adjustment.
POSITIONER MALFUNCTION
- Voltage to pressure transducer disconnected.
- Voltage to pressure transducer failure.
COLD START - Start-up or reset due to power supply failure.
OUTPUT FIXED
- Operating in local mode with fix position.
- Connected in burnout.
OUTPUT SATURATED - Position out of calibrated span or in fail-safe (Output current in 3.9 or 21 mA).
2 OUT OF LIMITS
- Temperature out of operating limits.
- Temperature sensor damaged.
1 OUT OF LIMITS
- Position out of operation valve range.
- Voltage to pressure transducer damaged or not connected.
- Positioner with error configuration.
LOWER RANGE VALUE TOO HIGH - The lower range value > (Upper limit of minimum span range).
LOWER RANGE VALUE TOO LOW - The lower range value < (Upper limit of range).
UPPER RANGE VALUE TOO HIGH - The upper range value > 110 % x (Upper limit of range).
UPPER RANGE VALUE TOO LOW - The upper range value < - 10 % (Lower limit of range).
