The KZP3-RS is used to obtain and maintain a category 4 level of safety for an installation with two control devices.
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.
