GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 5 - Components and Functions (Theory) 5 - 137 5-11-4 TX Power Supply 5-11-4-1 General Description The TX Power is a switch mode power supply module. It is used to generate two symmetrical pairs of digitally programmable voltages for the transmitters in the Vivid 7 scanner. A fixed Probe MUX voltage with either +/- 95 VDC or +/- 100 VDC, depending on TX Power Supply model, is used by the multiplexers in Linear Array and Convex probes with more than 128 transducer elements. • It is enclosed in a metal frame that slides into the Card Cage. • The module connects to the Motherboard (Backplane) through a 32 pin connector • One or two guide pins, located between the two upper mounting screws, fits into corresponding hole(s) in the Card Cage. This “key” is used to pr event it from being plugged into scanners that use similar, but not comp atible power supplies. - The TX Power with one guide pin is used in Vivid 7 produced with software version v3.x and earlier, and without 4D. - The TX Power with two guide pins was introduced for use in Vivid 7 with software version v4.0, and is needed for all Vivid 7 with 4D.

The Front-End Card Rack stops functioning, the perip herals and the monitor also looses its power. On units with an internal UPS, the Back-End Processor automatically switch over to the internal battery, and the Back-End Processor starts an automatic power down sequence.

GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 5 - Components and Functions (Theory) 5 - 141 Section 5-12 Mechanical Descriptions 5-12-1 General Description, Top Console on Vivid 7 NOTE: Vivid 7 PRO is described in section 5-12-4 on page 5-145. The Top Console includes Monitor, Monitor Shelf, Speakers and Operator Panel. The Console’s movement backwards and forwards and to the sides is made possible by the Frogleg unit that links the Top Console to the rest of the S ystem in a flexible multi movement joint. The handle (XY-release Handle) that unlocks the Frogleg, is located in the center lower side of the Front Handle. The Top Console can also be moved up and down. The handle (Z-release Handle) is located in the left grip of the Front Handle. A gas spring inside the sy stem assists in the Z movement. It is actuated by pulling the Z-release Handle and at the same time lifting up or pushing down the Console with some pressure to assist up/down motion. A flexible harness of electrical and mechanical wir es secures the connection between the Top Console and rest of the System.
