FlowCon ABM DYNAMIC BALANCED TEMPERATURE CONTROL VALVE Actuators The ABM valve should be installed so that the actuator is located upwards and higher above the valve center-line to prevent condensation into the electronics. Valves are supplied in open position. Figure 2 Manual over-ride operation 1) DISCONNECT POWER. Failure to disconnect power may cause damage to the actuator gears. 2) Fit the manual over-ride key onto the valve spindle. 3) Press the clutch. 4) Rotate the manual over-ride key to open or close the valve as required. CW will close the valve and CCW will open the valve. Figure 3 Mechanical installation 1) Depress the clutch and manually close the damper blades and position the actuator at 0° or 90° so that the damper and the actuator coincide. NOTE: do not clutch the actuator when the power is on. 2) Slide the actuator onto the shaft. 3) Tighten the nuts on the “U”-bolt to the shaft with an 8mm wrench to a torque of 6.7Nm. 4) Slide the mounting bracket under the actuator. Ensure free movement of the slot at the base of the actuator. The bracket pin must be placed in the mid distance of the slot. Actuator wiring 1) Remove the actuator cover by loosening the cover screw. 2) Connect the wiring, pls. see figures 4-7. Screw-terminals 6, 7 and 8 are only used on actuators with end switches. 3) SW1 controls the direction of the rotation, please see figures 4-7 for clock-wise (0 to 90°) and counter-clock-wise (90 to 0°) rotation. 4) For actuators with end switches, the mechanical auxiliary switches are fixed at 10° and 80°.
