Mounting and Wiring Variable Air Volume Modular Assembly PDF fileMounting and Wiring Variable Air Volume Modular Assembly (VMA) 1400 Series Controllers Technical Bulletin 8 When using a single transformer to power multiple VMAs, use a wire gauge large enough to handle the current and minimize the voltage drop. The voltage drop depends on the current draw, wire gauge, and wire length. Valves and Actuators | Johnson Controls The new, patented Johnson Controls 270° six-way valve and actuator signals a new direction for chilled beam and fan-coil applications. It minimizes the number of valves and actuators required, which provides more control, greater accuracy, more efficient energy use, and – ultimately – improved occupant comfort. M9208-xxx-x Series Electric Spring - Johnson Controls PDF filesubordinate actuator lags the master actuator position by a few seconds. IMPORTANT:Do not install multiple M9208-GGx-x Series Actuators connected to the same mechanical load. Master-subordinate application of M9208-GGx-x Series Actuators requires that each actuator be connected to independent loads. Figure 2: M9208-GGx-x Control Wiring Diagrams VA-7010 Series Electric On/Off Actuator - Johnson Controls PDF file• Make sure the actuator is free of thermal insulation material. • Leave at least 0.8 in. (20 mm) clearance above the actuator for mounting purposes. (See Figure 3.) To mount the actuator on a VG5000 valve: 1. Place the threaded coupling over the valve stem and the bonnet. 2. Rotate the actuator Johnson Controls Actuator, Electric Actuators - NECC Johnson Controls Incremental and Proportional Light Duty Electric Actuators for Valves. The VA-715X Series synchronous motor-driven actuator provides incremental and/or proportional control of valves with up to 3/4" stroke. These non-sring return electric actuators have a 90 lb. force output for on/off-floating or proportional control.
