Stryker Secure II
Q: I have a Secure II bed that any time you press an articulation function, the bed automatically raises to the high position, even if I remove my hand from the footboard. The bed will just continue to rise on its own to the highest positions. I am guessing it is a limit switch somewhere. Any suggestions?
A: Disconnect your side rail cables. It sounds like you have a stuck key.
Reply: Thank you for that response. The bed will go down while operating the down button, but when you release it raises back up. In fact, if I take the cowl off the underside of the bed it will stop going down if I press the down limit switch, but then the bed goes back up, even without touching the controls.

Q: What would cause the left/right arrow keys on display to not work? I can turn on the embedder and can turn on into service mode. All buttons seem to work. The light turned on when pressing the “light” key and all double beeped. I can’t move the cursor left or right to select the test run, I can only select “program version” because that is where the cursor starts when turning it on in service mode.
A: “All buttons seem to work.” Including the arrow keys? I would try cleaning the contacts on the flat flex cable from the front panel, and carefully reinserting it into the connector on the main board.

Q: What does error code (Errnum) 1818 pertain to? Sym code ENCB
A: Encoder B error. I’d check the encoder connections, verify that the volumes haven’t fallen out of calibration to that on the display. Make sure there is no contrast leakage onto the power drive card.
Puritan Bennett 840
Q: I have a Puritan Bennett 840 ventilator and the touchscreen stopped working. The display is working only the touch is not. I checked the cable assembly touch frame and it does work. Where else should I start looking for the problem?
A: Screen lock key. It may be activated. Try to disable or try cleaning the screen with alcohol-free liquid.
Reply: The screen lock key is not activated. I cleaned it and it is still not working.
A: You need to replace the GUI touch board, if it’s not working after cleaning. Make sure no stickers or damage is on the screen or black housing.
A: The touchscreen board is a square board that is held on with plastic pins. Also check the ribbon cable. The newer boards have a different ribbon cable than the old ones. That causes issues as well. A defective keyboard can also cause issues that may look like a touchscreen as mentioned above. Test it before putting everything back together.
