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

·Magnetic coupling for stem force limitation and self-

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.

Fig. 8. Auxiliary switch cables

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.
