2 1.5T SRFD3 RF fault code and Error Condition/Recommended Actions

Table 1 contains a list of 1.5T SRFD3 RF fault code and Error Condition/Recommended Actions. If the fault code is not listed in the table, then contact the OLC for support

Table 1. 1.5T SRFD3 RF fault code and Error Condition/Recommended Actions
Fault Code	Error Condition and Recommended Actions
2254585	[SRFD3 detected a power supply fault] Check coolant flow/temperature. Check inside of Cabinet is not Over temperature. If coolant flow/temperature and cabinet temperature OK and the fault persists, may need to replace SRFD3.
2254367	[SRFD3 detected a peak current overload condition in one or more RF devices] Check that system center frequncy consists of 8 digits and is correct. Check RF Amp error(s) that may point to the real cause don't precede this error(s). If so, then invetigate preceeding error(s) first. Check Exciter RF Output and Cable between SRFD3 and Exciter. If fault persists, replace SRFD3.
2254587	[SRFD3 detected an RF device shorted fault] SRFD3 will attempt to bypass this failure and run in low power mode. If the bypass is successful, message number 2254054 will appear. Order an RF Amplifier and replace the bypassed unit as soon as the new one arrives. The customer can scan with this configuration unitl the new RF Amplifer arrives. Bypassing the failed FET is NOT a parmanent fix. The penalty for bypassing an output FET is about 6.25% reduction in maximum RF output power. If the FET failure cannnot bypassed, the SRFD3 must be replaced immediately. The site will not be able to scan.
2254588	[SRFD3 detected High Voltage Low fault] Power cycle the SRFD3 so that the power is off for 3 minutes and then attempt to Scan. Check incoming AC line phases to SRFD3. If fault persists, replace SRFD3. (It is difficult to know how long the unit will run. You may want to order an amplifier in case the unit fails within the next fer days.)
2254589	[SRFD3 detected High Voltage High fault] Power cycle the SRFD3 so that the power is off for 3 minutes and then attempt to Scan. If fault persists, replace SRFD3. (It is difficult to know how long the unit will run. You may want to order an amplifier in case the unit fails within the next fer days.)
2254372	[SRFD3 detected a heat sink temperature fault] Check coolant flow/temperature. Check inside of Cabinet is not Over temperature. If coolant flow/temperature and cabinet temperature OK and the fault persists, may need to replace SRFD3. (Additional time may be required to allow the system to cool, e.g. 15-20 minutes.)
22545395	[SRFD3 detected Peak Power fault] Perform BODY AND HEAD MAXIMUM POWER RF OUTPUT CHECK. Check Exciter RF output and RF Cables. If the problem persists, may need to replace SRFD3.
2254396	[SRFD3 detected Average Power fault] Check that same fault ocurrs with other standard PSDs. (Usually this fault happens because the scan PSD is exceeding the limits of the amplifier using reserch mode or customer built PSD). Perform BODY AND HEAD MAXIMUM POWER RF OUTPUT CHECK. Check Exciter RF output. If pulse sequences are acceptable, and the fault persists, may need to replace SRFD3.
2254397	[SRFD3 detected a reflected power fault] Visually check all connections in Body or Head transmission lines for damage from the front of SRFD3 to where the connections are made to the RF coil. Perform BODY AND HEAD MAXIMUM POWER RF OUTPUT CHECK. If all connections are good and the Maximum Power RF Output check is passed, and the problem persists, may need to replace SRFD3 or contact OLC for support.
2254398	[SRFD3 detected an RF device junction temperature fault] Make certain that this error isn't being preceeded by another in the error log. If another RF error preceeds it, troubleshoot the other error first. Check coolant flow/temperature. Check inside of Cabinet is not Over temperature. Confirm that the system center frequency consists of 8 digits and is correct. If other potential sources have been eliminated and the fault persists, replace SRFD3.
2254596	[SRFD3 detected Undefined fault] If fault persists, replace SRFD3.
2254584	[SRFD3 detected a J20 cable fault] Check cable connection between SRFD3 J20 and ASC Lite. Replace cable if defective. If problem persists, may need to replace ASC-Lite or SRFD3.
	[SRFD3 was shutdown by the UPM due to RF safety limits being exceeded] Possible UPM fault or system issue. Check patient weight value entered by customer for scan and make sure it has not been significantly under-reported. Check TG from customer scans and make sure if it has not invresed from what it is normally due to a system hardware problem. Investigate the cause of any substantial increase in TG. Check Config File Mgr and make sure Start TA, Coil Loss and Cable Loss values for the coil in use when the fault happens are correct. Check the cable connections between SRFD3 and ASC Lite. Perform UPM functional check. If needed, perform UPM Power Monitor Calibration. If fault persists, contact OLC for support
2254597	[SRFD3 detected a Watchdog Timer fault] If fault persists, replaceSRFD3.
2254598	[SRFD3 detected a Watchdog Clock Monitor Fault] If fault persists, replace SRFD3.
2254599	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254600	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254601	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254602	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254603	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254604	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254605	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254606	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254612	[SRFD3 detected a Watchdog Timer fault] If fault persists, replace SRFD3.
2254607	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254611	[SRFD3 detected a code flash fault] Perform the reboot of the system or TPS reset (Re-try the software download). If fault persists, replace SRFD3.
2254608	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254609	[SRFD3 detected an Unrecoverable Firmware Fault] If problem persists, replace SRFD3.
2254054	[SRFD3 in low power state] SRFD3 has the ability to bypass some types of RF FET failures in the event that one should occur. If this message appears in the log, check to make sure that it was preceded by Error Message Number 2254587, which indicates a true RF FET failure. The FET failure may have occurred at some point prior to the user first noticing this message about the low power state, and the FET failure message will log only once. This error message will appear every time a TPS reset is performed as a reminder to the operator that scanning is limited until the amplifier is replaced. The ultimate solution is that SRFD3 must be replaced. The low power state allows the site to continue scanning at reduced output until a replacement is installed.
