I run a small print shop and am having a problem with my paper cutter. I was adjusting the brake mechanism because the cutter blade was stopping late in its return cycle. Similar to a automotive disk brake, I apparently over tightened the adjustment and put too much of a load on the main motor upon restarting(220 3 phase). The internal breakers kicked off (3 - 20amp). I re-adjusted the brake with plenty of clearence, but now when I energize the circuit, it runs for about 10 seconds and then shuts off. Also, it is turned on with a push button switch that also powers up an air pump motor, which will energize even though the main motor won't. Internal breakers are not popping off now.
Question: Could I have damaged the contactors when the circuit initially overloaded? It appears it needs a "recovery" time before it can be restarted again.I have looked for overload heaters to reset but find none. Electrically, everything was fine untill I wrenched on it...Any help would be appreciated.
