GE MEDICAL SYSTEMSPROPRIETARY TO GE D IRECTION 2294854-100, REVISION 3 LOGIQ™ 9 PROPRIETARYMANUAL 7-72 Section 7-13 - Troubleshooting TiPs 7-13-1 Soft Keys There are several Soft keys to be utilized on the LOGIQ™ 9: •Alt + F4 = Shut Down •Alt + F10 = is the SW Shut Down. This is very important tool to shut-down the system. If there is something problem with the I 2C bus you can shut-down the system by using this Alt + F10 keys. If the systems can easily be shut-down by using these keys it means that SW is working fine so the problem could be the I 2C bus, ON/OFF switch or the wire that carriers shut-down signal. •Alt +F5 or F11 for the echo simulator. 7-13-2 Power Supply 7-13-2-1 Noise on FEPS Fans • Check the part number of your FEPS. It should be 2260203 Rev H or Rev J. If not, the site may be eligible for FMI 70168 (Part Number 2340861) • Replace the power supply. 7-13-2-2 HV Errors • HV faults will show up whenever the TD boards have HV out of specification. Check FEPS voltages. You can visually check the LED status on the FEPS and on EQ (for HV). If any of the Power supplies is missing, there will not be HV output. If this is the case the Power Supply needs to be replaced. • Run Diagnostics on the Power Supply to check the voltages and their tolerances. Refer to 7-7-4-8 System-Level Analog Diagnostics on page 7-29. It will show you all the voltages including the Pulser HV (~ +120V) and HVP (+100V) and HVN (-100V). Pulser HV is generated on the FEPS and goes straight to the TD boards; HVN and HVP are generated on the EQ board from the Pulser HV. If HVN and/or HVP are the only ones missing, replace the EQ board. If Pulser HV is missing, replace FEPS. • Remember that Pulser HV won’t be present if you don’t have any probe connected. NOTE: You may find older power supplies that have a –15V supply. This power supply is not used on the system; newer FEPS don’t even have it present.
