Actuator Mounting on Dampers
Damper actuators must be mounted correctly for proper operation.
What You Might Be Looking At
small motor mounted on side of damper, with linkage connecting to damper shaft
Apprentice words: motor on damper, damper motor, control motor, actuator box
Trade terms: damper actuator, motor actuator, damper motor, control actuator
Check First
What Not To Do
Don't mount actuators without manufacturer instructions. Don't assume all actuators mount same way. Don't force linkage onto wrong shaft type.
What can go wrong: Actuator can't open/close damper, controls commissioning failure, damper damage, energy waste, underperformance
Better Foreman Question
For this damper actuator, which mounting orientation and linkage type does manufacturer specify? Verify shaft direction before mounting?
Verify With
Reference type: manufacturer install instructions, controls submittals
Source to verify: Actuator manufacturer guide (Belimo, Siemens, Honeywell), controls submittal drawings
Safe wording: Actuator mounting varies by damper manufacturer and actuator model. Controls wiring must match BAS design.
