KMC CONTROLS MEP-4000 Crank Arm Kit Actuators
Mounting
- From the MEP-4xxx actuator, remove and discard the V-bolt.
- Assemble and install the kit and actuator as shown in the diagram below.
NOTE
- In general, position both the ball joints as close to the end of the crank arms as is feasible for the application. Positioning a ball joint in the slot closer to the shaft will change the torque, rotation speed, and/or angle of rotation—which may be useful for some applications.
- Check for potential issues such as binding of the linkage or damage caused by the actuator still rotating when the damper (or other application) is already closed.
- See the Accessories section for an auxiliary crank arm if the damper or other equipment does not have one already installed.
- For much more information about installing MEP-4xxx actuators, see the MEP-4xxx Applications Guide on the KMC website (www.kmccontrols.com) as well as the relevant installation guide.
Maintenance
Under normal conditions, no routine maintenance is required. In harsh
environments, however, periodic lubrication of the ball joints may be
necessary.
Each component is designed for dependable, long-term reliability and
performance. Careful installation will also help ensure long-term reliability
and performance.
