M847D Series Actuator Specifications
The Honeywell M847D series actuators are designed as two-position‚ 24 Vac spring return damper actuators. These actuators are primarily used to operate directly driven zone dampers‚ controlling airflow in ducts. The M847D utilizes a synchronous motor which can be driven open or closed using any 24 volt rated two-position switch‚ such as a thermostat subbase switch. The actuator is designed to mount flush with the damper box and drives from 0 to 95 degrees‚ returning to 0 degrees via spring action. It’s important to note that the actuator is operated by an SPST two-position controller. When the controller contact makes‚ the actuator drives the damper to the fully open position. Upon contact break‚ the spring returns the damper to the closed position. The M847D series also includes a self-centering shaft adapter. The actuators are typically pre-wired for ease of installation. They feature a declutch for manual adjustment when needed. The M847D is engineered to provide reliable control for air damper applications. They are suitable for dampers up to 4 m2‚ depending on air friction. Mounting considerations include avoiding the bottom of the damper in unconditioned spaces to prevent condensation issues. Torque specifications are also essential for proper function and installation;
Installation Guide for M847D Actuators
Before initiating the installation of the Honeywell M847D actuator‚ it’s critical to carefully read all instructions to avoid any hazardous conditions. Begin by unpacking the damper and carefully installing it into the ductwork. For ducts with insulation‚ ensure that the insulation is slid under the actuator and taped to the actuator’s outer flange to create a proper seal. In unconditioned spaces‚ it is important to mount the actuator only on the side or top of the damper. Mounting on the bottom may lead to condensation dripping into the actuator. When mounting the actuator‚ place it and its mounting bracket back into the correct position‚ and securely attach the bracket to the damper box using sheet metal screws. Use a 10 mm wrench to tighten the shaft coupling onto the damper shaft‚ applying a torque between 120 lb-in and 180 lb-in. Avoid overtightening‚ as this could potentially damage the actuator. For dampers with a 7/16 diameter coupling‚ insert the drive shaft extension into the drive shaft before installing the M847D actuator. Ensure the actuator is mounted flush with the damper box. Always double-check wiring connections. Refer to the manufacturer’s instructions for proper wiring diagrams and safety precautions.
Mounting Options and Considerations
When mounting Honeywell damper actuators‚ several options and factors need to be considered to ensure proper functionality and longevity. The primary consideration is the location of the actuator relative to the damper. In unconditioned spaces‚ actuators should be mounted on the side or top of the damper to prevent condensation from dripping into the mechanism‚ which could cause damage; Actuators are typically designed to mount flush with the damper box‚ providing a secure and stable connection. Some older dampers may have different shaft diameters‚ which could require shaft adaptors‚ though Resideo no longer offers these for some models. The actuator should be securely mounted using appropriate hardware‚ such as sheet metal screws‚ with specific torque requirements. The shaft coupling must be tightened properly to ensure a stable connection to the damper shaft. Tightly securing the actuator to the damper housing can damage the actuator‚ so care must be taken not to overtighten. The actuator drives from 0 to 95 degrees and spring returns back to 0. Ensure the mounting position allows for the full range of motion. It’s also essential to choose a mounting location that allows easy access for maintenance and manual adjustment.
Manual Adjustment and Operation
Honeywell damper actuators often include features for manual adjustment and operation‚ allowing for control even without an active control signal. The actuator can be operated with no power supply using the manual positioning feature. Many actuators come with a declutch mechanism that allows manual adjustment of the damper position. This declutch feature is essential for setting the initial position or making temporary adjustments. A manual thumbwheel or a similar mechanism may be present for fine-tuning damper settings. The actuator can be driven to the desired position by manually operating the declutch. Some models include an auto/manual switch to facilitate manual operation. This switch should be set to the manual position to override the automatic control. After making manual adjustments‚ the switch can be returned to the auto position for normal operation. The actuator’s control signal dial can be used to adjust the input signal for the actuator. These manual features are useful during installation‚ testing‚ or troubleshooting and provide a backup control method if the primary control system malfunctions. These manual adjustments should be made carefully to avoid damage to the actuator or damper.
Troubleshooting Common Issues
When dealing with Honeywell damper actuators‚ several common issues may arise. A frequent problem is a sticking damper‚ where the actuator fails to fully open or close the damper. This can often be due to mechanical binding or obstructions. Check for any physical obstructions in the damper or actuator mechanism. Another common issue is actuator failure‚ where the actuator does not respond to control signals. This can be caused by a faulty motor‚ wiring issues‚ or a problem with the control system. Wiring should be checked for loose connections or damage. Actuators may also fail due to condensation build-up‚ particularly if mounted improperly. Ensure proper mounting‚ especially in unconditioned spaces. Problems with the control signal can also lead to issues. Verify that the controller is sending the correct signal and that the actuator is receiving it. If the actuator is making unusual noises‚ it may indicate internal damage. In some cases‚ an older actuator may have a different shaft diameter which the new actuator will not fit. If the actuator has failed‚ replace the damper. Lastly‚ make sure the actuator is rated for the damper’s torque requirement.
Maintenance and Care
Regular maintenance is crucial for ensuring the longevity and optimal performance of Honeywell damper actuators. Begin by visually inspecting the actuator for any signs of damage‚ such as cracks‚ loose connections‚ or corrosion.
