Observe wire sizing and transformer sizing requirements. Proportional models CANNOT be connected to Belimo direct coupled (AF, AM, GM…etc) actuator power supplies or any type of half-wave device. You MUST use a separate, dedicated transformer or power supply to power the SY actuator. Please do not connect other automation equipment to the dedicated SY supply source. You MUST use four wires (plus a ground) to control a proportional control SY actuator (See SY Wiring Section).SY6-120MFTModulating, Non-Spring Return, 120 V, for 2 to 10VDC or 4 to 20 mA800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 03/26/2018 - Subject to change. © Belimo Aircontrols (USA), Inc.Wiring DiagramsINSTALLATION NOTES60Do not change sensitivity or dip switch setting with power applied. 61Power supply Common/Neutral and Control Signal “-”wiring to a common is prohibited. Terminals 4 and 6 need to be wired separately.62Isolation relays must be used in parallel connection of multiple actuators using a common control signal inputs. The relays should be DPDT.63Isolation relays are required in parallel applications. The reason parallel applications need isolation relays is that the motor uses two sets of windings, one for each direction. When one is energized to turn the actuator in a specific direction a voltage is generated in the other due to the magnetic field created from the first. It’s called back EMF. This is not an issue with one actuator because the voltage generated in the second winding isn’t connected to anything so there is no flow. On parallel applications without isolation, this EMF voltage energizes the winding it is connected to on the other actuators in the system, the actuators are tying to turn in both directions at once. The EMF voltage is always less than the supply voltage due to the resistance of the windings, so while the actuator still turns in the commanded direction, the drag from the other reduces the torque output and causes overheating.!WARNING! LIVE ELECTRICAL COMPONENTS!During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
