OPERATING MODE
The expansion module is used to increase the number of outputs of a safety relay according to VDE 0113. Several expansion modules can be connected to one safety relay. A supply voltage must be applied at terminals A1 and A2 in order to operate the device. If this is done there is a voltage of 24V DC at terminal U1. Terminals K21 and K1 must be wired as shown in the application examples. To start the module, closed safety circuits from the safety relay must be connected with K21 and K1 and contacts 13-14,
23-24, 33-34, 43-44, 53-53, 63-64, 73-74 and 83-84 close. The LED\'s channel 1 and 2 illuminate. The fault LED illuminates if one or more safety circuits are open. The fault LED will be illuminated while the expansion module relay is operational.
