What did the Abbotts ever do to him is my question because I can't think of anything. The auxiliary switch is double insulated so an electrical ground connection is not necessary.Īdd on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.The way Tucker was scrolling through the pictures of the Abbotts, has me really interested in what he is plotting if anything. The switching function is adjustable 0 to 95Â°. This SPDT switch is provided for safety interfacing or signaling, for example, for fan startup. The LMB24-3-S version is provided with 1 built-in auxiliary switch. Power consumption is reduced in holding mode. The ASIC monitors and controls the actuatorâ€™s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. The LMB24-3â€¦ actuators use a sensorless Brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC).

The gears can be disengaged with manual release on the actuator cover. When reaching the damper or actuator end position, the actuator automatically stops. The LMB series provides 95Â° of rotation and a visual indicator which indicates position of the actuator.

The anti-rotation strap supplied with the actuator will prevent lateral movement. The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. Shafts up to 3/4â€ diameter can be accommodated by an accessory clamp. The actuator is mounted directly to a damper shaft from 1/4â€ up to 5/8â€ in diameter by means of its standard universal clamp. Actuator sizing should be done in accordance with the damper manufacturerâ€™s specifications. For On/Off and floating point control of dampers in HVAC systems.
