Q: I received a call to the OR and the staff reported the table had a burning smell coming from it. I verified the smell and also found that the pump continues to run as soon as you plug it into AC. I removed the hand controller and still the pump runs. I checked override switches and foot lock switch under AC receptacle. I am looking for suggestions.
A: Check the actuation solenoid on the control panel. If it was fused shut, it will run continuously. It is soldered on the board, but you can replace or swap the whole board.
A: I believe you are going find one of the following:
1. Bad control board.
2. The motor is activated by the control board applying a ground.
So you could have a short in the wire going from the motor to the control board and that is keeping the motor running all the time. Just a thought.
A: Most likely it is the power control board mounted on the inside cover of the power supply assembly. Disconnect P1 & P3 from the table control board (box on column with cover) this eliminates the control board. Disconnect P7 from the overide board (top of column without cover) this eliminates the overide board. If the pump is still running, replace the power control board or the complete power supply assembly.
Q: I have a Zoll E series monitor that does not recognize the ECG cable. I tried the same cable on another device and it works. The cable is new. I tried to replace the connector and also the flat cable that connects the ECG connector to the electronic board without any result. It always appears ECG lead off. Can someone help me?
A: Sounds like it’s your main system PCB and or possibly the system interconnect PCB.
A: Since you have switched out the ECG connector and the ECG cable and no results, the only component left is the system board. It may have blown fuses or something. You may want to switch out with a good system board to confirm it.
A: Possibly unplug your analyzer, it may have interference. Check to see if the is frequency set to 60HZ? Also check to see if you have a damaged ECG connector.
