  • Introduction
  •  
The JC22-PL2-1006 is housed in a durable metal enclosure with a removable cover.The JC22-PL2-1006 is a direct replacement for the Hays Cleveland model # 9502-1012-B-8. The JC22-PL2-1006 provides automatic modulation for any negative or positive draft application.SpecificationsWeight & Dimension: 21 lbs. 17.5” L x 7.5” W x 5.9” HPower Requirements: 120 VAC, 50/60HzMotor: 72 RPM synchronous motorSample Connection: ¼” NPT female fitting Ambient Temperature Range: 0 to 140F (-18 to 60C)

► Offers a 6-inch range of travel with a 60-second nominal stroke time. The JC22-PL2-1006’s thrust range is rated at 150 lbs with a cool-running 72 RPM synchronous motor.

►The actuator is self locking in the “last” position if there is a power loss.

► Preferred’s JC22-PL2-1006 interfaces with your burner management system:

○ The JC22-PL2-1006 is a sequencing draft controller.

○ Includes burner management interfacing relays for automated Open damper during Purge, and Closed damper after shutdown.

○ Includes an Automatic/Open selector switch. This allows the user to blow soot without interrupting the burner firing and allows the burner to fire in the “Open” damper mode under emergency conditions.

► Sensing and control functions offered via the PID controller are as follows:

○ A solid state sensor provides an accurate, low drift signal to the controller.

○ Field-adjustable Set Point for both positive pressure and negative draft applications.

○ Adjustable Sensor Dampening to reduce the effects of flame induced draft pulsations.

○ Adjustable Proportional Band for control of the rate of actuator movement in relation to the set point.

○ Adjustable Dead Band to prevent actuator “hunting” near the set point.
