User manual HONEYWELL M7410E

[. . . ] They are used in fan-coil-units, induction units, small reheaters and recoolers, and for zone control applications. They are employed in electronic temperature control systems with hot and/or cold water as the controlled medium. [. . . ] 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 long-term reliability. The M7410E actuators are also compatible with any controller providing intelligent position control and having a built-in shutoff function. The M7410E actuators are well-suited for applications in which space is limited and minimum power consumption is required. They feature an attractive and rugged design. ® U. S. Adjust the valve in the correct position before mounting the actuator. Fig. Mounting the actuator EN0B-0634GE51 R1008 2 ELECTRICAL WIRING A fuse with a contact gap of at least 3 mm for each pole must be fitted with the fixed installation. The electrical installation must comply with the wiring diagram shown in Fig. 6. COMMISSIONING ADVICE A functional check can be carried out by changing the controller setpoint by 5 °C or more. The movement of the actuator stem (see Fig. 7) indicates whether the valve is opening or closing. 230 VAC: L 2A VDE 0641 IEC 269 M Fig. [. . . ] 7) indicates whether the valve is opening or closing. 230 VAC: L 2A VDE 0641 IEC 269 M Fig. Movement of actuator stem WHITE GREEN Fig. [. . . ]
