KMC Controls MEP-46 Q Series User manual

1
DESCRIPTION AND APPLICATION
These compact but powerful direct-coupled ControlSet®
actuators provide 90° rotation within three seconds. A
minimum torque of 54 in-lb. is available over the 95° angular
rotation. These actuators are designed for dampers or
valves in critical HVAC, laboratory fume hood, and life-safety
applications.
Efcient, durable, capacitor-driven fail-safe operation (in
MEP-4652Q/4672Q) with switch-selectable direction provides
consistent torque in both powered and fail-safe modes.
The actuators offer proportional or two-position control.
Two-position control mode is designed for use with on/off
switches, thermostats, or controller outputs.
Proportional control mode accepts either a 0–10 or 2–10 VDC
control signal input from a thermostat or controller. With an
external 500 ohm resistor, a 0–20 or 4–20 mA control signal
is also accepted. A switch-selectable, 0–5 or 0–10 (or 1–5
or 2–10) VDC voltage feedback output is proportional to the
actuator position and is standard on all models. “Anti-jitter”
circuitry signicantly reduces hunting and needless wear
(from unnecessary miniscule position changes caused by
undamped analog input signals) on the actuator, valve, or
damper components. A user-initiated, auto-mapping feature
provides more precise equipment control by reassigning the
input signal range over a reduced rotation range. The feature
also provides “soft stall” protection (from stalling hard against
a physical stop) that extends actuator life.
MEP-4622Q and MEP-4672Q models also have two built-in
SPDT auxiliary switches for remote position indication or an
auxiliary equipment interface. One switch is fully adjustable (0
to 90°) and the other is xed at 10° from full CW direction. A
three-foot cable is included with the switches.
All actuators mount directly to 1/4- to 5/8-inch (6 to 16
mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm) square
shafts, eliminating the need for expensive and complicated
linkages. A non-rotation bracket, to prevent lateral movement,
is included with each actuator. A gear disengagement button
allows easy manual positioning of the actuator.
