Hi
I want to switch an air compressor off from a timer that i have attached the link that i will be using. The compressor is a 3 phase star delta unit and i have attached schematic for it. My question is do i simply put the timer between the coil of the contactor KM1 and use the output of the timer to switch the coil on it or do i have to put it elsewhere in the circuit seeing as it is star delta? The current set up has no timer on it it just has a direct start and stop on it on the front panel on an LCD panel.
