Issue
The customer is replacing a defective actuator on a hot water reheat valve downstream of a VAV box. The VAV and associated hot water valve are controlled by a DMS MicroSmart MSC-V-511 controller.
Can the MF41-6043 actuator be wired into the MSC-V-511 and control the valve?
Environment
DMS
MSC-V-511
MF41-6043
Cause
Defective actuator is discontinued and cannot be swapped with an identical, working one.
Resolution
The triac outputs on the MSC-V-511 can properly control the MF41-6043 actuator.
- Terminals D1 to D4 provide 24 Vac which is the voltage required for the actuator.
- Look at the MSC-V-511 installation guide (F-25710) on page 18 for details on how to wire and program the actuator.
-
Remember that the MSC-V-511 provides 24 Vac power so there's no need for an external power source.
- If needed, the MF41-6043 installation guide has wiring diagrams on page 6.
- The actuator requires 2.3 VA. The digital outputs on the MSC-V-511 can provide up to 12 VA.
