Test voltage input to actuators and repair as necessary if voltage is not correct. Old breakers often deliver below 115V and failed actuators may be due to power supply problems. Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015...
Page 4: Local Code Approval
Local Code Approval While it is not detailed in codes, the following rules should be followed for selecting Belimo actuators for replacement: Check the technical specifications to ensure an “equal or better” actuator is used.  Temperature – the replacement actuator shall have been UL555S tested at the same or better temperature as the original actuator.
Page 5: Cross Reference
UL555S testing. larger sized damper use the UL listed sizing. “What’s New” Each manufacturer tests Belimo separately www.belimo.us/firesmoke and has different sizes UL555S listed. for a cross reference by manufacturer. Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015...

Page 7: Application
The motors above are connected by linkage as shown in the photographs below. The Belimo FSLF can be direct coupled if space exists for mounting. A bracket may have to be fabricated from 16 ga. Sheet metal to hold the anti-rotation strap. The geometry of the situation determines the mounting method.
Page 8 Replace the fusible link if necessary and test the closing Test when reattached to ensure function. the damper closes if fusible link melts. THIS SPRING AND FUSIBLE LINK MUST REMAIN IN PLACE. Greenheck MP2985 & MP2986 Motors with Belimo FSxx Series January 2015...
Page 9 Close-up view showing external shaft spring and part of the linkage. Both will be removed so that the Belimo can be mounted on the shaft. Crankarm is connected to the damper shaft. The Belimo may be direct coupled over the shaft. For short shaft mounting, place clamp of actuator between actuator and damper.

Page 11 Remove spring, bracket and MP motor. Do not remove bearing or bracket. Jackshaft extends beyond the outboard bearing bracket and the Belimo FSLF can be direct coupled. A plate will be needed to attach the anti-rotation strap. An alternate plate is available from Greenheck and is shown below.
