Depending on the degree of safety required, KNA3-XS / KNA3-RS / KZP3-RS can receive the following components as inputs: - pushbutton for start or validation (Y1-Y2) - emergency stop pushbuttons with one or two contacts (A1-A2) one or two contacts (A1-A2) two contacts KNA3-RS: Y11-Y12 and Y21-Y22, two contacts KZP3-RS: Y11-Y12 / Y21-Y22 and Y31-Y32 / Y41-Y42 - position sensors (limit switches) with one or two contacts (A1-A2) two contacts KNA3-RS: Y11-Y12 and Y21-Y22, two contacts KZP3-RS: Y11-Y12 / Y21-Y22 and Y31-Y32 / Y41-Y42 A positive break operation device must be used if a single channel is used. To increase the degree of safety, one "N/C" auxiliary contact per power contactor is wired in series with the start (or validation) pushbutton, to ensure self-checking in this part of the installation. The KNA3-XS has three "N/O" safety contacts (13-14/23-24/33-34) and one "N/C" signalling contact (41-42). One or more control devices may be wired up to the breaking capacity of the safety contacts: 1500 VA. However, to limit internal heating, it is advisable not to exceed 10 A thermal for all three contacts. The signalling contact can be wired on a PLC input or integrated into a fault signalling system. The number of contacts can be extended and the breaking capacity thus increased. To do this, use the KZE3-XS. : KNA3-RS Leg.
