There are eight switches in a row on the
circuit board, see figure 6.
Note! Switch 0% / 60 s, 300 s /
50%
has a double function, see below!
M400: On delivery, all switches are in
the “OFF” position except for the third
one.
Control signal—MOD/INC
M400 can either be controlled by an
increase/decrease signal or by a
variable direct voltage, a so called
modulating signal, so a certain voltage
level corresponds to a certain position.
Sequence or parallel control—
– – –/SEQ
With sequence or parallel control, two
actuators can be controlled by only one
control signal.
You can choose which part of a voltage
range to use, the upper one 6-10 V
(5-10 V) or the lower one 2-6 V (0-5 V).
If the switch »NORM/INV« is in the
NORM position, the higher voltage
corresponds to 0% flow and the lower
one to 100%. To achieve the opposite
function, the switch »NORM/INV«
should be put in the INV position.
Note! If sequence or parallel control is
not used, the switch »– – –/SEQ« must
be in the left position, as the switch for
modulating or increase/decrease
control »MOD/INC« is not valid during
sequence or parallel control.
Voltage range—2-10/0-10
You can choose whether to use the
control signal voltage range 2-10 V or
0-10 V.
Part of voltage range—
6-10, 5-10/2-6, 0-5
You can choose which part of a voltage
range to use, the upper one 6-10 V
(5-10 V) or the lower one 2-6 V
(0-5 V). If the switch is in the NORM
position, the higher voltage corresponds
to 0% and the lower one to 100%. To
achieve the opposite function, the
switch should be put in its INV position.
Running time—60 s/300 s
During increase/decrease control, you
can choose between 60 s or 300 s
running time. During modulating control,
the running time is always 15 s/20 s.
Security function—0% / 50%
At 2–10 V control signal you can select
which security function you want the
actuator to have.
If the actuator is used for heating
control and switch 5 is ON (50%), the
actuator will open the valve halfway if
the control signal disappears, e.g. if the
X1 connection is unplugged.
If, instead, you want the valve closed,
set switch 5 to OFF (0%).
Note! The direction of movement is also
significant. See Installation Instruction
0FL-4006.
Direction of movement—NORM/INV
When normal direction of movement is
used, the screw of the actuator moves
inwards when the control voltage
decreases or if the actuator gets an
increase signal. With the switch
»NORM/INV«, the direction of
movement can be changed.
Linearization—NORM/LIN/LG
It is possible to choose whether the
motorized valve characteristics should
be affected or remain unchanged. If
you wish for the characteristics to be
affected, the choice »LIN/LG« will make
the characteristics of an equally
modified percentage (EQM) valve
almost linear. A motorized valve
equipped with a linear valve will operate
with “Quick open characteristics”, i.e.
when the control signal is only
increased a little, the valve will be
almost completely open.
Note! For the actuator to register new
settings of the switches, the supply
voltage must be cut or the manual
operation handle lowered when the
settings are done, and then it must be
raised again. (This does not apply to
the switch »OP/ADJ«.)
End position adjustment—OP/ADJ
The switch is used to adjust the end
positions when the actuator is in
operation.
