Q: I am having an intermittent error #157 that comes at the end of the scan and while the tech is getting the patient out of the bed. Has anyone had this error before? I checked all the cables from the SEM to motor drivers, all good. Is there anything else that I am missing?
A: On which axis is it occurring? Since you have already checked the cables, I would look at either the SEM PCB or the driver.
Reply: Every time the error comes up it has a different axis # with it, which makes it very confusing, and I don’t know which way I should go.
A: Info on the drivers. The Motion Controllers comprise two drivers: Driver for Table Up/Down, Radial 1 and 2 (and Lateral when Radials are disabled). Driver for Table Backward/Forward and Swivel 1 and 2. No guarantees, but I would go for the SEM board.
Q: My Harmony LA300 is drifting. What can I tighten so the light doesn’t drift? It will get to a certain point when I’m moving it down then just drop the entire way.
A: Do you see a covering on the arm that is dropping? You’ve got vertical drift, there should be a cover you can remove, maybe halfway up the arm. Pull off that cover and you should see a castle nut, if you don’t, move the arm up until it comes into view. If you don’t have a spanner wrench, you can use an Allen key or screwdriver to adjust it, just put something between it and the hole so you don’t scuff it.
Q: Is it possible to deactivate (set the default to “off”) for the requirement for entering a three-digit code when initiating a pre-programmed therapy?
A: You should be able to change the keypad code from “code” to “key” so programming will be available whenever the latch is unlocked.
Go to tasks > adjustadmin settings > enter admin code > Security > keypad security
Q: CR doesn’t complete the self-test. It shows error service 2249F.
A: The error means: 2249F
