Have you checked for any safety micro switches on the machine, or dodgy stop button not retracting properly. Sometimes relays click out need resetting, so may be worth checking those too. (Of course I have to recommend only qualified electricans should be poking around inside a machine....., if machine is not isolated there is risk of a shock and pushing in the motor relay/s will bypass the switch and could start the motor running)Karl":1wcurv4o said:Thanks Bright Spark.
I'm probably barking up the wrong tree. Just wired up my 2nd hand panel saw which has star delta. First time i've used one. Normally all three lives can be connected to any terminal on the plug, if it's spinning backwards, switch 2 over. Fine. But i've wired this machine up, and nothing. There is power going to it, the digital speed readout lights up, and the brake/emergency stop buttons work fine. But switch on the star/delta switch, and nothing.
