Control devices :
Depending on the degree of safety required, KNA3-XS can receive the
following components as inputs :
- emergency stop pushbuttons with one or two contacts (A1-A2)
- position sensors (limit switches) with one or two contacts (A1-A2)
- pushbutton for start or validation (Y1-Y2)
A positive break operation device must be used if a single channel is
used. (diagram 1)
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. (diagram 2)

Control devices :
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
(diagram 1 and 2) up to the breaking capacity of the safety contacts : 1500
VA. However, to limit internal heating in the KNA3-XS, it is advisable not to
exceed 10 A thermal for all three contacts. The signalling contact cannot be
used as a safety contact. 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 of the KNA3-XS can be extended and the breaking
capacity thus increased. To do this, use the KZE3-XS (see page 11/20).
