If the safety system (NLG+ESPE) is correctly supplied, the input terminals of the module are activated (light beams not interrupted) and there aren’t fault conditions, the module is enabled to close the safety outputs and the external contactors can be energized. When the input terminals are not activated (light beams interrupted) 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 (NLG02...A) or S33 and S34 (NLG13...A) are connected, the safety outputs close and the auxiliary output opens (NLG13...A) as soon as both the module inputs are activated. The relevant CH1 and CH2 LED turn on. Deactivating even one module input forces immediately the safety outputs to open and the auxiliary output (NLG13...A) to close. A new operating cycle is possible only after deactivating both input contacts and then operating them again. Manual START Provided that both the module inputs are activated, the safety outputs close and the auxiliary output opens (NLG13...A) as soon as the NO START pushbutton is pushed connecting X1 and X2 (NLG02...A) or S33 and S34 (NLG13...A). A new operating cycle is possible only after deactivating both the module inputs, activating them again and pushing the START button. Monitored manual START The monitored manual START versions (NLG...C) work as described in the previous paragraph (Manual START) except for a minimum delay of 500 ms from the activated status of the module inputs to the pushing of the START button. If the inputs of the module are closed with the START switch already closed, the safety outputs don’t close and the auxiliary doesn’t open (NLG13...C): it is necessary to release the START button and deactivate the module inputs before starting a new cycle, then operate the inputs of the module 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.
