Lumenis VersaPulse PowerSuite 80/100W
Q: At first, I had the laser connected to a 220V step up transformer. Sometimes it would turn off due to the step up transformer not having enough power for the laser, but sometimes it would stay on and go through the screens with no issues. I decided not to run the laser until we hooked it up to a True 220v line that we were thinking of hooking it up to. So, the issue that I am having now is that after adding the distilled water to the reservoir due to low level of water, I turned on the machine, and now I’m getting a red screen with a message that says “Casesaver Feature” activated. I clicked continue and it went to the laser control screen, but with limited power. So, I decided to run the true 220V line to our basement to run the machine directly to a 220V line, but when I turned it on, that “Savecase Feature” mode was still popping up. Does anyone know how to disable “Savecase Feature” mode?
A: The case saver feature does not turn off. The PowerSuites have 4 heads internally that together make 100W of holmium laser. When one or more of the heads is not functioning efficiently enough, the laser runs at limited power. If the max is 60W @ 40Hz, then 1 head is down. If 30W, then 2 heads are down. Open up the laser and check the rods and mirrors.
REPLY: Thanks for the info. What am I looking for when checking the rods and mirrors?
A: Any kind of optical damage. They will appear as spots/burns. Typically, in order to cause it to go into case saver, the spots will be greater than or equal to 1 mm in diameter. Also, the laser’s burns should be round 4 mm spots. If they are slitted like a cat’s eyes, that could also be an issue. If that is the case, then alignment is required.
GE Logiq e BT12
Q: I have been using the Logiq e BT12 which I bought refurbished a year ago. A couple of days ago I started having this problem where the machine will shut down randomly after 10 minutes of being on and it will be very hot. I couldn’t try to turn it back on immediately. I have to wait a bit. I take out the battery and put it back in and then it works again but, of course, for only 10 minutes until it shuts down randomly. I don’t get any error messages from the device. I am wondering what the problem could be because the seller who sold me the device has no idea. Could it be an overheating problem (I have cleaned the filter and fans, everything is working) or is it the power supply or something else?
A: There are several things that can get hot in a Logiq e. Some of them, like the DC-DC power supply and TMST board, should give a warning before the system just shuts down. We have seen hard drives that run very hot before they fail completely. The fans are critical for cooling the system. There are two fans on the left side near the front of the system and two on the right side in back of the probe connector, and it is possible that one or more of them is not turning.
