M6410C/L, M7410C

Small 3-Position Linear Valve Actuators

PRODUCT DATA

FEATURES

• Small size allows installation where space is limited

• Low power consumption

• 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-off-point

• Reversible synchronous AC motor

• Suitable for three-position modulating control without

proportional feedback

• Supplied with pre-wired connection cable

• Simple, standardized valve/actuator coupling; no

tools required for mounting

• Visual valve position indicator furnished with

actuators

• Manual operation provided by the valve adjustment

cap, extra knob, or with a hexagon key

• Auxiliary switch

GENERAL

The Honeywell M6410C/L and M7410C actuators are specifically designed to provide floating control together with the V5822/23 and V5832/33 series of small linear valves.

The M6410C/L and M7410C actuators are used in fan-coilunits, induction units, small reheaters and recoolers and for zone control applications. They are employed in electronic temperature control systems using hot and/or cold water as the controlled medium.

The M6410C/L and M7410C actuators are suitable for Honeywell Excel series controllers as well as for Honeywell individual room temperature controllers. These controllers track the precise valve position by counting the number of individual control pulses which move the valve from one position to another. For this reason, the actuators do not need end switches or a feedback potentiometer. The absence of these mechanical components ensures longtime reliability.

The M6410C/L and M7410C actuators are also compatible with any controller providing intelligent position control and having a built-in shut-off function.

These actuators are well suited for applications where space is limited and minimum power consumption is required. The actuators are both attractive and robust in design.

OPERATION

The movement of the electric actuators 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

MOUNTING

Before the actuator is fixed to the valve, you must remove the adjustment cap (Fig. 2). Make sure that the actuator is in the retract position (factory-supplied position) before fixing the actuator to the valve body.

COMMISSIONING ADVICE

A functional check of the valve actuator can be carried out by changing the controller setpoint by 5 °C or more. The movement of the actuator stem (Fig. 6) indicates whether the valve is opening or closing.

AUXILIARY SWITCHES

The actuators with the OS-number M*****40** feature two auxiliary switches, each with its own cable. Auxiliary switch S1 switches when the stem reaches its fixed Auxiliary switch S2 switches when the stem reaches its adjustable

switchpoint.

Adjustment of Auxiliary Switch 2

Auxiliary switch 2 should be adjusted by a skilled person, only.

Move the actuator to the position where the switch is to be tripped. Cut the plastic skin with a sharp knife. Below the skin, the adjustment screw can be accessed. 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.

MANUAL OPERATION

The actuators with integrated manual operation (see Table 1) feature a hexagonal key hole for manual operation. For more comfort, an additional knob for manual adjustment is packed separately. To avoid damaging the valve, separate the actuator from the power supply before adjusting manually.
