1 M0 ROTARY VALVE ACTUATORS PRODUCT DATA FEATURES Protected against overload and blocking Maintenance-free electrical actuator for rotary valves Clear position indicator Direct mounting on rotary valves Manual operation High torque Large wiring cabinet Long lifetime APPLICATION The Honeywell M0 actuator is designed to provide modulating control in heating and air conditioning systems. High control performance and a robust design are standard for this actuator. In combination with valves DRxxxGMLA / DRxxxGFLA, ZRxxxMA / ZRxxxFA, and DRU, it is possible to control very exact heating and cooling water temperatures. The mechanical interface between actuator and valve is designed for reliable operation. Actuators with torques from 0 Nm up to 0 Nm are available for a wide range of rotary mixing valves (DN up to DN 00).

2 M0 OPERATION The actuator is powered by a DC-motor. The spindle of the actuator rotates 0. The position is controlled by internal electronics. PCB ST ST R L declutch button hand lever position indicator R knob R Adjusting Spindle to Feedback Potentiometer The position of the spindle can be adjusted to match the signal from the feedback potentiometer using knob R (see Fig. ). With the motor in the center position (the mark on the hand lever must line up with the mark on the motor housing), the graduation on knob R must point to the triangle on the PCB (factory setting). Adjustment is required only if the printed circuit board is changed for servicing. Actuator Characteristic The actuator characteristic, i.e. the relation between motor rotation and the input signal Y, can be altered to suit the given valve using potentiometer (see Fig. ). The curve of the characteristic between its start and end points can be adjusted infinitely between convex, linear and concave (see Fig. ). Potentiometer is marked with the numerals through. The linear characteristic = is the factory setting. 0 0 PL potentiometer 0 0 PR terminals = potentiometer PL potentiometer PR Fig.. Main features The angle of rotation is electronically limited and can be adjusted (see section "Angle of Rotation"). The spindle can also be rotated manually by using the declutch button (see Fig. ) to disengage the gear and then turning the hand lever. As soon the actuator is powered, the valve is driven by the actuator again. An electrical overload circuit protects the actuator. If the rated torque is exceeded, the actuator is switched OFF automatically. The actuator is maintenance-free. Commissioning and Service Direction of Motor Rotation The direction of rotation can be defined using jumper ST (see Fig. ). ST in "L" (left) position (factory setting): clockwise rotation 0 00% (i.e. when Y = 0 Vdc, the hand lever is at the left end) ST in "R" (right) position: counterclockwise rotation 00% 0 (i.e. when Y = 0 Vdc, the hand lever is at the right end). Input Signal Y The input signal Y can be set using jumper ST (see Fig. ): ST in the upper position (factory setting): Y = Vdc ST in lower position: Y =...0 Vdc = = = = 0 0 0% = = = 0% Fig.. Characteristic curve = = Y 00% Examples When mounting the proportional actuator onto a valve with a linear characteristic, an equal percentage characteristic on the controlled unit can be achieved by setting a concave curve ( ). An actuator used together with an oversized mixing valve is a further application requiring a concave curve ( ). Angle of Rotation The angle of rotation is adjustable via the potentiometers P L and P R (see Fig. ). Start and end points can be adjusted independently. EN0B-00GE R00

3 M0 The nominal angle is 0 (0 = 0 ); the potentiometers are factory set as follows: P L = and P R = 0. These settings are marked by a square. The desired angle can be adjusted by changing the start and end points; within the total range, all angles are possible. The start point can be adjusted between 0 and 0 using potentiometer P L, while the end point is adjustable between 0 and 0 using potentiometer P R. Fig. shows an example setting of the angle rotation in which the start point has been set to and the end point to 0, and Fig. shows the corresponding relation between the input signal and the angle of rotation. potentiometer PR To override the input signal Y, i.e. in order to control the position from an external source, connect to motor terminals as follows: for a signal variable of 00%, connect terminal to terminal for a signal variable of 0%, connect terminal to terminal (system ground or ground wire). 0%: 00%: 0 0 PL potentiometer PL Fig..
