GE DMR Plus Error E04 and E71 Assistance
April 15, 2019 10:31
We have a GE Seno DMR+ mammography unit giving the following errors:
E04 - Arm Fatal Failure - 027/002
E71 - Bucky Failure - 118/012
Any advise in resolving this would be greatly appreciated.

Hello gli have problem on Grid.
Grid don't move probabily meccanica problem or not Voltage on Motor or Motor broken

Did you try another bucky? Most probably the solenoid which moves the grid is faulty. Contact me at firstname.lastname@example.org
E04 GEN None Arm fatal failure Generator detects

Switch OFF Gantry, then switch ON.
If the problem continues, note ALL
messages and contact GEMS Field
E71 GAN Bucky Fail Bucky Failure Bucky cannot be
moved under normal
1. Remove Bucky.
2. Reinstall Bucky.
3. Make a Rad Prep.
4. If failure continues, note ALL
messages, and contact GEMS Field

I believe you have a grid movement issue.
118/012 is a limit of travel not found error caused by:
- There is abnormal friction. If the effort to produce movement is too high, the gain is artificially raised. An overcurrent detection is also possible.
- Too high gain and/or wrong offset
- defective photo-interrupter (F1) on 800-PL10
- Motor cannot move (open voice coil wires, defective electronic circuitry)
- Motor only moves in one direction - defective electronic circuitry (800-PL1)
- Optical end-of-travel cannot be reached before mechanical stop: 800-PL1 not centered.

Hi Craig, I have a problem with the same equipment. It display the errors E04 037/001. Can you hlep me. My e-mail is email@example.com
027/002 means the grid start signal was not received or grid fault detected.

118/012 Grid movement: limit of travel not found
027/002 Grid sync: grid start signal not received or grid fault detected

027/002 Grid start signal not detected or grid fault detected. 118/012 Grid movement - limit of travel not found. You can check for grid motor voltage at 800 PL10 corner XJ2. you can check Hall Effect, on grid, approximately 8 ohms. Hall sensor is +4V(+/- 50mV)without any magnetic field measured on TP1/TP2(800-PL10)

Hell I have problem with dmr+ and error 158/019 lateral collimator. Does anyone know solutionr? At start up machine motor drives and blades move to sensor and then in other position.

Did you check the belt tension?
