Help please.....

Philip Snyder All Messages By This Member #138077 I have a 2002 Hammer C3-31 combo machine and it was a floor model and wasnt able to try it out till I rented a truck and a 2 ton fork lift and get it in my shop. When I did I discovered it was very underpowered and had a reverberating vibration.? I talked with the Felder folks and after much back and forth they agreed to send two 3 KW motors to replace my 2.2 KW motors, but no instructions and I had to install and hook up myself. ?So I commissioned an electrician once I did the work of installing motors.? He as able to get it running and ive been using for years, but I have been experiencing the following issues:? after 5-10 minutes with he table saw on the power switch flips and I have to wait 5 or more minutes before it will engage when? flip the main power button on machine.Another issue is if I bump it it will cut off, (but that may be a safety thing??. ?I mostly remedied the vibration with a dampening blade from Forrest.??Can anyone offer and advice/guidance?? Thanks in advance.? Cheers!
imran All Messages By This Member #138078 开云体育 Philip, What do you mean by “after 5-10?minutes with he table saw on the power switch flips” On felder, no on/off switches flip on their own. Do you mean that the saw just turns off? If not a picture would help. Also by power switch, do you mean the switch to turn the saw on or the main power cutoff? You use, power switch, more than once do it always mean the same switch. Another issue is if I bump it it will cut off, (but that may be a safety thing? Bump what? The switch that turns the saw on? I would also need the electrical schematic to offer any help.

Steve Rowe All Messages By This Member #138082 I suspect thermal overload settings are still set for 2.2kw motors instead of the 3kw motors.? The thermal overload settings can be adjusted and I would talk to Felder about where those are on your machine and how they should be adjusted.? I have had to make this adjustment on a Minimax J/P that would just arbitrarily shutdown even when running with no load.? The location of the adjustment on the Minimax was on the main power switch.? Hope this helps. Steve
Steve Rowe All Messages By This Member #138083 I forgot to mention that you may also want to check for any loose electrical connections since you have had vibration issues.? This could also cause tripping of thermal overloads. Steve
imran All Messages By This Member #138084 开云体育 Hi Philip, I don’t like to shoot in the dark but what Steve mentioned is a distinct possibility. I do not have much experience with Hammer but Felder designs commonly use an overload relay with an adjustable current setting. This could be the source of your issue. In my KF this relay resets itself, after cooling, if in auto reset mode. In Felder schematics K1 typically controls the motor and F1 (overload relay) is physically attached to it. If you are capable of troubleshooting with a multimeter it is easy to confirm that the overload relay has tripped. You can call Felder for assistance or send me a PM if you need further help. I still would need a copy of the schematic to assist. Imran Malik toggle quoted message Show quoted text On Nov 9, 2024, at 7:41?AM, Steve Rowe via groups.io <steverowe734@...> wrote: ?

ibsenafshar All Messages By This Member #138234 Philip, given how inaccessible the motors are I wonder how you were able to swap them?
imran All Messages By This Member #138241 开云体育 Hi Ibsenafshar, ? Thanks for sharing the schematic. So there really is a single start switch for all functions? ?

ibsenafshar All Messages By This Member #138242 There was one start and two stop buttons when I got it. I have added a start and a stop button on the left side.
imran All Messages By This Member #138243 开云体育 Seems pretty inconvenient to only have one start switch, especially when you have a big machine to walk around.
