APPLICATION
The Honeywell M7410E actuator is specifically designed to
provide modulating control together with the V5822/23,
V5832/33, and V5825B series of small linear valves.
The M7410E is used in fan-coil-units, induction units, small
reheaters and recoolers, and for zone control applications. It
is employed in electronic temperature control systems with
hot and/or cold water as the controlled medium. This actuator
is fully compatible with all controllers providing 0...10 V or
2...10 V output signals.
The 7410E actuator is designed for applications where space
is limited and minimum power consumption is required. A
microprocessor-based, high-performance positioner
guarantees accurate control.
Reliable longtime operation is ensured due to the fact that no
mechanical feedback potentiometer and no mechanical end-
switches are needed. Due to an automatic synchronization
function, the close-off point is self-adjusting.
Based on a running time of 150 s, valve positioning and flow
adjustment is very exact. Manual positioning is provided for
all actuators. The actuator is both attractive and robust in
design. A special version with auxiliary switch is available.
FEATURES
·Microprocessor-based positioner ensures precise
stem positioning
·Small size allows installation where space is limited
·Low power consumption

signal (adjustable on site)
·Easy-to-operate direct/reverse acting switch
·Simple input signal override (e.g. for frost protection
function)
·Reliable longtime operation because mechanical
feedback potentiometers and mechanical end
switches are not required

adjustment of the close-of-point
·Supplied with pre-wired connection cable
·Simple, standardized valve/actuator coupling. No
tools required for mounting
·Visual valve position indicator furnished with
actuator

OPERATION
The movement of the electric actuator is produced by a screw
spindle which is driven in both directions by a synchronous
motor through a set of gears. A magnetic clutch limits the
torque of the gear assembly and the driving force of the
actuator. The actuator is fixed to the valve body by means of
a coupling ring requiring no tools for mounting. The actuator
is maintenance-free and supplied completely with a ready-to-
wire connecting cable.
A microprocessor-based high performance positioner
guarantees accurate control. The close-off position is self-
adjusting by means of an automatic synchronization function.
Synchronization is performed when the applied control signal
is 0 V or 10 V. The actuator then drives every minute for 5
seconds into the end position in order to ensure close-off
even after manual operation.

MOUNTING POSITION
The actuator may only be mounted beside or above the
valve. Adjust the valve in the correct position before
mounting the actuator.
Fig. 1. Mounting positions
MOUNTING
Before the actuator is fixed to the valve, the adjustment cap
must be removed (Fig. 2). Make sure that the actuator is in
the open position (factory-supplied position) before fixing the
actuator to the valve body.
Fig. 2. Remove protection cap
The actuator must be mounted by hand. Do not use tools or
additional force insofar as this may damage the actuator and
valve.
Fig. 3. Mounting the actuator
SWITCH SELECTION
The built-in selector switches must be set according to the
valve type (2-way or 3-way), valve size, and the controller
output signal (0...10 V or 2...10 V), see Fig. 4.

INPUT SIGNAL OVERRIDE
To override the controller output signal, the input signal must
be connected to COM (0 %) or 24 V (100 %) using an
external switch (see Fig. 5).

MANUAL OPERATION
Actuators with the OS-number M7410E2... and M7410E4...
feature a hexagonal key hole for manual operation. For more
comfort, an additional knob for manual adjustment is packed
separately. To prevent valve damage, operation is permitted
only when there is no power applied to the motor.

COMMISSIONING ADVICE
A functional check of the valve actuator can be carried out by
changing the Y input signal. The movement of the actuator
stem (Fig. 7) indicates whether the valve is opening or
closing. If the direction of travel is not correct, the
direct/reverse-switch must be reset.

AUXILIARY SWITCHES
The actuators with the OS-number M7410E4022 and
M7410E4033 feature 2 auxiliary switches. Each switch has
its own cable. Auxiliary switch S1 with fixed switchpoint when
the stem position is in. Auxiliary switch S2 with adjustable
switchpoint when the stem position is out.

Adjustment of Auxiliary Switch 2
The auxiliary switch should be adjusted by a skilled person,
only. Move the actuator to the position where the switch is to
be operated. Cut the plastic skin with a sharp knife. The
adjustment screw can be accessed below the skin. Turn the
screw clockwise until the end stop is reached. Turn the screw
counterclockwise until the switch point is achieved. To check
that the required position has been set, move the actuator.
Finally, seal the adjustment hole with a piece of tape.

Electric Wiring of Auxiliary Switches
The electrical installation must comply with the wiring
diagram shown in Fig. 10. If the auxiliary switch is connected
to 230 Vac, a switch with a contact gap of at least 3 mm for
each pole must be fitted with the installation.
