If the unit is correctly supplied and the input terminals are closed (i.e. E-Stop not pushed), the module is enabled to close the safety outputs and the external contactors can be energized. When the input terminals are open (i.e. E-Stop pushed) the module is not enabled to close the safety outputs and the external contactors can not be energized. 2 Automatic START Provided that the terminals X1 and X2 (NES02...A) or S33 and S34 (NES13...A) are connected, the safety outputs close and the auxiliary output opens (NES13...A) as soon as both S1 and S2 switches are closed. The relevant CH1 and CH2 LED turn on. Releasing even one input contact (S1 and/or S2) forces immediately the safety outputs to open and the auxiliary output (NES13...A) to close. A new operating cycle is possible only after releasing both input contacts and then operating them again. Manual START Provided that both S1 and S2 switches are closed, the safety outputs close and the auxiliary output opens (NES13...A) as soon as the NO START pushbutton is pushed [connecting X1 and X2 (NES02...A) or S33 and S34 (NES13...A)] A new operating cycle is possible only after releasing both input contacts, closing them again and pushing the START button. Monitored manual START The monitored manual START versions (NES...C) work as described in the previous paragraph (Manual START) except for a minimum delay of 500 ms from the closed status of the input contacts to the pushing of the START button. If the input terminals get closed with the START switch already closed, the safety outputs don't close and the auxiliary doesn't open (NES13...C): it is necessary to release the START button and the input contacts before starting a new cycle, then operate the input contacts and finally, after at least 500 ms, operate the START button. So if the NO START button gets welded, the outputs don't close anymore.
