After the supply voltage is applied to terminals A1/A2, and after being activated through an enabling current path of the basic unit, the relays K1 and K2 switch into their operating position. After this switch-on phase, the four enabling current paths 13/14, 23/24, 33/34, and 43/44 are closed, the normally closed contact 51/52 and the feedback contact X1/X2 are opened.

Function Diagram
If the enabling current paths of the basic unit are opened by actuation of the E-Stop switch, then relays K1 and K2 of the SNO 3001-xx switch back to their de-energized position. The enabling current paths open the normally-closed contact and the feedback contact close. The feedback contact X1/X2 prevents the basic unit from switching on again if K1 or K2 do not drop out.

The basic unit is triggered with the "RESET" command through the feedback loop of the expansion unit. Please take note of the information provided by your Professional Association! 4,5
Single-Channel Control Circuit: The enabling current paths 13/14 of the basic unit are connected to the terminals Y11/Y13 of the exspansion unit. The terminals Y12/Y13 are shunted.
