N 562/11 Switching actuator, main module
3x AC 230/400 V, 10 AX, C-load, load-check
Product and functional description
The switching actuator main module N 562/11 is a DIN-
rail mounted device with N-system dimensions. It can
switch three groups of electrical consumers, independent
of each other, via its three relay contact outputs. The bus
is connected via a bus terminal block. The actuator elec-
tronics are supplied via the bus voltage.
Connection of switching actuator submodules
A switching actuator submodule N 562/21 or N 512/21
(see device B in figure 1) can be connected to the switch-
ing actuator main module N 562/11 (see device A in
figure 1) via the 6-pin interface with a special jumper. A
further switching actuator submodule can be connected
likewise to a previous switching actuator submodule. In
total up to 4 switching actuator submodules N 562/21 or
N 512/21 can be connected in series to a switching ac-
tuator main module N 562/11, so that a main module, if
need be, can be extended simply from a 3-fold to a 6-, 9-,
12- or 15-fold switching actuator and thus be matched
flexibly to the size and number of loads to be switched.
LED display
Five green light emitting diodes (LED) on the top of the
main module (see figure 2, A5) indicate which module is
selected (LED = ON). A module can be selected by tap-
ping the pushbutton "Direct mode" (see figure 2, A6)
once or several times until the LED of the desired module
A to E illuminates. If any of the green LED A to E is flash-
ing a fault was detected at this module. For example, this
is the case if more modules are configured than are actu-
ally connected or if the configured module type does not

correspond with the module type actually connected or if
a module is detected as faulty.
Bus mode / Direct mode
The Direct mode pushbutton (see figure 2, A6) with an
integrated yellow LED may be used to toggle between
Bus mode and Direct mode. If this pushbutton is pressed
briefly, the associated green LED indicates for 30 seconds
which of the modules A to E (see figure 2, A5) was se-
lected last and the switching state of the corresponding
outputs is indicated by the red LED integrated in buttons
1 to 3 (see figure 2, A9; relay contact closed: LED = ON,
contact open: LED = OFF).
However, if the button to switch on Direct mode is held
down for at least 3 seconds, then the yellow LED to indi-
cate Direct mode turns on permanently. In Direct mode,
each output of the currently selected module can be
switched via the allocated pushbutton on the top of the
main module through a toggling function: a first press on
the pushbutton switches the output on if it is switched
off, a second press switches it off again. The switching
state of the output is indicated by the red LED incorpo-
rated in the pushbutton. (Note: Pushbuttons 4 to 6 and
the incorporated LED are not used in the N 562/11.) To
change the switching state of the outputs of another
module, this module must be selected first. To do this,
you must briefly press the Direct mode pushbutton sev-
eral times until the LED of the desired module A to E
illuminates. Modules that are connected but not yet set
up as connected cannot be selected.
A parameter determines whether Direct mode can be
switched on permanently or for a limited period. The
factory default setting limits the Direct mode period to
15 minutes. Each time the pushbutton is pressed the
timer is reset to 15 minutes. After the period has elapsed
without a further key press, Direct mode is switched off
automatically and Bus mode is re-enabled accordingly (if
communication via the bus is possible). Alternatively,
Direct mode can be left at any time by pressing the Direct
mode pushbutton for at least 3 seconds. Then the yellow
LED for indicating Direct mode turns off and the actuator
operates in Bus mode. In Bus mode, pressing the
pushbutton for direct switching of an output off or on
does not work. If Direct mode is active, switching and
scene recall commands received via the bus are buffered
and automatically executed after switching back to Bus
mode.
Behavior in case of mains failure / recovery
Because the actuator electronics are fed from the bus, a
mains failure then leads solely to a failure of the actuator
function if the bus voltage also fails as the result of a
mains failure. However, it can be set for each actuator
output individually which switching state it is to assume
on a bus voltage failure and after the bus voltage recov-
ery: as before bus voltage failure, ON or OFF.
