SQM4 Linkageless Actuators

3-torque ratings

SQM45 » 30 in-lbs SQM48.4 » 180 in-lbs SQM48.6 » 310 in-lbs

Internal protection prevents actuators from damage as a result of over torque

Internal thermostat prevents actuator from over-heating

Same mounting footprint for all models

Adjustable stroke timing via AZL keypad

SQM4 CANbus Technology

Digital CANbus signal offers high accuracy and safety

900 motor positions in 90° of rotation of the stepper motor

Digital feedback signal ensures accurate positioning

LOCKOUT will occur if actuator is out-of-position

System continuously monitors the integrity of CANbus wiring

Actuators are daisy-chained on single cable

SQM4 Actuator Commissioning

No calibration required!Actuators factory shipped in zero positionActuators will automatically re-position themselves

Actuator addressing via CAN-bus

Direction of rotation is easily changed via AZL display

ID, serial numbers, date codes automatically stored in LMV

VSD - Variable Speed Drive Sensor

Used to Vary Speed of Combustion Air Blower

Fully Characterized Curve Speed Curve

Advantage: Reduced Power Consumption & Reduced Noise!!!
