User manual HONEYWELL M7410C DATASHEET

[. . . ] 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.

Adjust the valve to the correct position before mounting the actuator. Fig. Remove protection cap The actuator must be mounted by hand. Do not use tools or additional force as this may damaged actuator and valve. Mounting positions MOUNTING Before the actuator is fixed to the valve, you must remove the adjustment cap (Fig. Make sure that the actuator is in the retract position (factory-supplied position) before fixing the actuator to the valve body.
