How to connect / wire a off delay timer with a 3 phase contactor ?
From 3 phases , each single phase goes to 2 heaters each (pair of 2 heaters) & the third phase goes to the 3 pair heater (pair of 3 heaters) , the neutral is common to every heater ........
the output of the Digital temperature controller , one of them goes to the off delay timer & one goes to the coil of the 3 phase contactor . I couldn't understand this
Kindly tell me how to reconnect these things together to complete the task of controlling the heater & blower system , blower also 3 phase
