4.5 Transducer Problems
Ultrasonic transducers are rugged, reliable devices. However, they are subject to physical damage from mishandling
and chemical attack. The following list of potential problems is grouped according to transducer type. Contact
Panametrics if you cannot solve a transducer-related problem.
4.5.1 Transducer Problems
• Internal Damage: An ultrasonic transducer consists of a ceramic crystal bonded to the transducer case. The
bond between the crystal and the case or the crystal itself may be damaged by extreme mechanical shock
and/or temperature extremes. Also, the internal wiring can be corroded or shorted if contaminants enter the
transducer housing.
• Physical Damage: Transducers may be physically damaged by dropping them onto a hard surface or striking
them against another object. The transducer connector is the most fragile part and is most subject to damage.
Minor damage may be repaired by carefully bending the connector back into shape. If the connector can not
be repaired, the transducer must be replaced.
IMPORTANT: Transducers must be replaced in pairs. Refer to Chapter 3, Programming to enter the new transducer
data into the meter.
4.6 System Errors (S-Errors)
These errors are from the Flow subsystem. The system errors have 4 types of information.
1. Indicator
2. Warning
3. Error
4. Fault
The indicator is just a notification to the operator, no action is needed. The warnings are usually indicative of an
operator error. Errors indicate failures that need attention. Operator should perform recommended actions to
recover from these errors. Faults are usually indicative of more serious failures related to background hardware /
software integrity checks performed by XMT1000 meter. See the table below for error codes, error messages, error
type and recommended actions.
Table 24: System Error Description and Recommended Actions
Error Code Error Message Description / Recommended Action
S1: In Config Mode In configuration mode indicator Indicator: This is displayed when a user has logged
in to either Operator, Admin or Factory access level.
The indicator will clear automatically when the user
logs out or saves the configuration changes
S2: Invalid User Invalid user warning Warning: The passcode entered for access level is
incorrect. Please log in with the correct access level
and passcode
S3: Invalid Request Invalid request warning Warning: An invalid communication packet was
received and discarded. Or, the requested
operation is invalid. Please send a valid packet or
operation request
S4: Invalid Param Range Invalid parameter range
warning
Warning: The value programmed for the parameter
was out of range and hence discarded. Please enter
a valid range
S5: Unsupported
Parameter
This parameter is not supported Warning: A read or write request to an unsupported
parameter was received
S6: Flow Measurement One or more flow measurement
channels are in error
Error: One or more flow measurement channels are
in error; accuracy of the measurement may be
compromised. For more details please check
flow(E) errors
S7: Persistent Param CRC Persistent parameter CRC fault Fault: Persistent parameter CRC failed. Try power
cycling the meter. If error persists after power cycle,
contact Panametrics factory
