Sakura – TISSUE-TEK VIP 6
Q: I have a vip6 that displays level sense errors when attempting to start a clean cycle. Process completes with no errors. When inspecting sensors I find paraffin buildup around sensors. Temps are within ranges. Any ideas?
A: It could be bad level sensors, but the front heater on the retort can fail and it will cause these errors. The retort may feel hot to touch and it will not give an heater errors, you can ohm out the heaters to see if they are out of range.
A: Clean the sensors. You don’t want any build-up on or around the level sensors. Each level sensor has a vertical slot on one side or the other. You need a brush that will get into that slot and clean it thoroughly.
Ritter Midmark 623
Q: I have a Midmark 623 I am currently working on and the base and back functions on the remote are only controlling the back and not the base (back up controls back up the three other functions lower the back).
All the fuses are good on the board so everything should be getting power, I have also checked the remote on other tables and the remote is wired correctly and works right on other tables.
The only thing I can think of would be some damage to where the remote plugs into the base of the table. Any ideas or insight would be much appreciated!
A: While you’re in there I’d check to see if the relays are working right. The service manual in the documents section shows you how on page B-20. It sounds like you may be looking at a new PC board though.
A: You may have solved this. If you are seeing damage to the connector. Otherwise check your cables. Functions not working could be bad actuators, cabling, relays, pcb.
But as far as an actuator being activated by the wrong button, the signal has to be going to the wrong place. Only 2 ways to do that, pins in the wrong spot or someone moved connectors around
Lumenis – VersaPulse PowerSuite 80/100W
Q: After the self test it shows me faults 35, 36 and 56. and a reduction in the maximum rate, the maximum power
A: Also, I just saw your earlier posts and it could be a brick going bad (there are 4). Usually that throws a brick failure code but maybe it’s partially working.
Good Luck!
