Principles
Control devices :
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
- position sensors (limit switches) with
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.
Control devices :
The KNA3 / KZP3 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.
Extending the number of contacts :
The number of contacts can be extended and the breaking capacity thus increased. To do this, use the KZE3-XS.
