Calibration: Collision sensor switch operation patient safety

Verify collision sensor switch inhibits DOWN elevator command when table top is in raised position; switch must release when table top is lowered

Ranked causes

1. Collision sensor switch not properly adjusted or collision bearing assembly misaligned (unknown)

First check

Table top installed and power turned ON

Test point: EV200 power
Expected: power ON

Calibration: SID switch positioning radiation

Set the 40 inch S.I.D. limit switch so film plane is 40 inches from x-ray source when depressed

Ranked causes

1. SID switch requires positioning adjustment (common)

First check

Measure distance from x-ray source to film plane when SID switch depressed

Test point: Bucky tray film plane to x-ray source
Expected: 40 inches

Collision sensor switch malfunction during DOWN command patient safety

DOWN elevator command not inhibited when table top is in collision position (lifted at corner), or DOWN elevator will not activate when table top is released

Ranked causes

1. Collision sensor switch not properly adjusted or bearing assembly not maintaining tension (common)

First check

Verify collision sensor switch inhibits DOWN when table top corner is lifted

Test point: collision sensor switch; DOWN foot pedal
Expected: DOWN elevator command inhibited (no movement)

Collision sensor switches not inhibiting DOWN command patient safety

When lifting table top corner and depressing DOWN foot pedal, switch fails to prevent downward motion, indicating improper adjustment.

Ranked causes

1. Collision sensing switch improperly adjusted (common)

First check

Verify collision sensor switch function

Test point: Each collision sensing switch
Expected: DOWN command inhibited when table top corner is lifted

1 corrective action and part numbers are in ServiceForge. Connect ServiceForge to your AI

Collision switch does not inhibit downward motion patient safety

Table top continues to move down when pulled up at corner, collision sensor fails to stop elevator

Ranked causes

1. Adjustable bearing assembly set below guide rail lower surface (common)

First check

Slide table top over adjustable bearing assembly

Test point: Adjustable bearing assembly
Expected: Bearing contacts lower surface of guide rail

Patient or operator contact with tubestand during height adjustment patient safety

Risk of collision or crush injury during tabletop height changes

Ranked causes

1. Inadequate clearance verification before height adjustment (common)

First check

Confirm clearance around table

Test point: Patient position, operator position, tubestand proximity, Bucky area
Expected: Patient and operator physically clear of all equipment

1 corrective action and part numbers are in ServiceForge. Connect ServiceForge to your AI

Risk of pinching or striking during table height adjustment patient safety

Patient or operator reports potential for contact with tubestand equipment or Bucky assembly during tabletop vertical movement

Ranked causes

1. Inadequate clearance awareness during height adjustment (common)

First check

Confirm clearance of patient and operator from tubestand and Bucky

Test point: Visual inspection around table perimeter, tubestand, and Bucky assembly
Expected: No personnel or patient limbs in collision path

Table does not lock without power patient safety

Patient or operator observes that table locking mechanism fails to engage when equipment is unpowered

Ranked causes

1. Table power is OFF (common)

First check

Verify table power switch status

Test point: Table power control
Expected: Power ON

1 corrective action and part numbers are in ServiceForge. Connect ServiceForge to your AI

Table locks inoperative patient safety

Table locking mechanism fails to engage or disengage; patient or operator cannot safely secure table position

Ranked causes

1. Table power is OFF (common)
