:confused: can anyone help with a safety relay problem, when the machine piowers up the safety relay AP-SFT SRU-MS-ILK11-6K does not light up channels 1 and 2, it says in the manual that its connected to the motor EMEGENCY STOP circuit. I think it should light channels 1-6 in sequence till all are lit then 1-4 should go out, i don't have a similar machine to compare is this correct?????

dear sir,

I thank I can help you if you email me the document of your machine. (ladder, electric diagram...and the photo)

thanks but managed to borrow some drawings and fix the fault found safety relay faulty replaced internal relays and all ok now thanks

Sometimes it is handy to go to the Manuf web site of the Safety Relay and get the condition/sequence chart for that particular model.
