Start
Control devices :
Depending on the degree of safety required, KNA3-RS can
receive the following components as inputs :
- emergency stop pushbuttons with two contacts (Y11-Y12 and
Y21-Y22)
- position sensors (limit switches) with one or two contacts (Y11-
Y12 and Y21-Y22)
- pushbutton for start or validation (Y1-Y2)
A positive break operation device must be used if a single contact
is used.
To increase the degree of safety, one "N/C" auxiliary contact per
power contactor is wired on terminals X1-X2 to ensure self-
checking in this part of the installation.

Control devices :
The KNA3-RS 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 in the KNA3-RS, 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-RS can be extended and the breaking
capacity thus increased. To do this, use the KZE3-XS (see page 11/20).
