M7410E SMALL MODULATING LINEAR VALVE ACTUATOR PRODUCT DATA APPLICATION 100%..0% 0%..100% 0..10V 2..10V 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 endswitches 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 Suitable for 0...10 V and 2...10 V controller output 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 selfadjustment 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 Manual operation provided by the valve adjustment cap, extra knob, or with a hexagon key EN0B-0097GE51 R1004 M7410E SMALL MODULATING LINEAR VALVE ACTUATOR SPECIFICATIONS Auxiliary Switches Motor Input voltage: Ratings: 24 Vac ±15%; 50/60 Hz 24...230 Vac, max. 3(1) A Power consumption: 1.4 VA Input signal: modulating 0...10 V, 2...10 V (adjustable); <0.1 mA Operation: direct/reverse (adjustable) Switch position (factory supplied): Stroke: 6.5 mm Running time: 150 s at 50 Hz 120 s at 60 Hz Stem force: depending on type (see table) 180 N (for valves DN 15..20) 300 N (for valves DN 25..40 and V5825B) Insulation class: III in accordance with EN 60730 Connection cable: 1.5 m Ambient operating temperature limits: 0...55 °C 0.4 kg Suitable valves: see table Manual operation: see table Switch S1 (fix) 17.8 ± 0.2 mm Switch S2 (adjust.) 11.7 ± 0.2 mm 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-towire connecting cable. A microprocessor-based high performance positioner guarantees accurate control. The close-off position is selfadjusting 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.

Adjust the valve in the correct position before mounting the actuator. 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. closes Y=+10V= A B factory setting opens Y=+10V= 100%...0% Y = 0...+10V A B 0%...100% 0...10V 2...10V factory setting opens Y=+10V= Y = 2...+10V A Fig. 1. Mounting positions AB B MOUNTING Fig. 4. Selecting valve type and output signal 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. ELECTRIC WIRING The electrical installation must comply with Fig. 5. 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). 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. 5. Connection of input switch Fig. 3. Mounting the actuator 3 EN0B-0097GE51 R1004 M7410E SMALL MODULATING LINEAR VALVE ACTUATOR 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. a b c a b c Fig. 8. Auxiliary switch cables 4 mm 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. Fig. 6. Manual operation 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. Fig. 9.
