!WARNING

High voltage and rotating parts may cause serious or fatal injury.

Turn off power to install or service.

Operate with guards in place.

Read and follow all instructions in this manual.

Because of the possible danger to person(s) or property from accidents which may result from the improper use or unapproved modification of the product, this product must be installed, maintained, and operated in accordance with the procedures, standards and engineering information specified in the product brochures and illustrations. To assure safe operation, this product should be inspected in accordance with the instructions described in this form. Proper guards and other suitable safety devices or procedures as may be desirable, or as may be specified in safety codes, should be installed by the user. Guards and other safety equipment are not provided, nor are they the responsibility of Emerson Power Transmis- sion.

1.0General Instructions

Prior to installation, inspect the coupling for any signs of damage that may have occured during shipment. Check that all parts are on hand and are as ordered.

ONLY BOLTS AND NUTS SUPPLIED BY

KOP-FLEX ARE TO BE USED.

Components should be cradled or supported during handling to avoid dam- age and should be wrapped for protection. Flanges and pilot surfaces should be kept free of nicks and burrs.

Read all of the installation instructions and review the procedure before the actual coupling installation.

2.0Installation of Coupling Hubs - Keyed Mounting

2.1Check the hub bore and shaft for nicks and burrs, dress if necessary. Make sure that the bore and shaft are clean.

2.2For tapered bores, check the fit of the bore to the shaft.

2.3Keys must be precisely fitted to the keyways in the shaft and hub. Each key should have a tight fit on the sides with a slight clearance on top. To maintain dynamic balance, the keys should fill the keyways exactly and not be too short or too long.

2.4Clean the hub bore and shaft. For straight bores, proceed to step 2.6. For taper bores, mount the hub handtight on the shaft and lightly rap it with a soft mallet to establish the initial line-to-line fit. This is the START position. With a depth gauge, measure the amount the hub overhangs the shaft end and record this value. See Figure 1.

DEPTH GAUGE

Figure 1. Measuring Hub Overhang

2.5Taper Bores Only: A recommended method to measure the hub ad- vance is to install a split collar on the shaft, away from the hub by the amount of the specified advance. Use feeler gauges for accurate spac- ing. See Figure 2. The amount of hub draw is dependent upon the desired interference and taper angle as specified by the machine manu- facturer or as given on the coupling drawing. See Figure 3.

2.6Heat the hub to expand the bore; DO NOT allow the hub temperature to exceed 600°F (300°C). DO NOT apply an open flame to any part of the coupling, an oven is recommended.

To avoid the risk of explosion, fire, or damage to the coupling and equipment, and/or injury to per- sonnel, do not use an open flame or oil bath to expand the hub. If heat is used at any time for in- stallation, DO NOT allow the hub temperature to exceed 600°F (300°C).

2.7Place the hub in the proper position on the shaft. Hold the hub in place as it cools. For taper bores, verify the hub advance (see Fig- ures 1 and 2) and install the shaft retaining nut. Remove the split collar from the shaft.

KD2, KD20 specifications

The Emerson KD20 and KD2 series represent cutting-edge advancements in the realm of process automation and control, particularly for industrial applications. These controllers are designed to provide exceptional performance and versatility, catering to various needs across sectors such as manufacturing, energy, and environmental management.

The Emerson KD20 is engineered for comprehensive data acquisition and control, offering a wide array of features that enhance operational efficiency. One of its standout characteristics is its advanced user interface, which includes a high-resolution display and intuitive navigation. This facilitates easy monitoring and adjustment of parameters in real-time, enabling operators to respond swiftly to changes in process conditions.

In terms of connectivity, the KD20 is equipped with multiple communication protocols, such as Modbus, Profibus, and Ethernet, ensuring seamless integration into existing systems. This flexibility allows the KD20 to communicate effectively with a range of devices, from sensors and actuators to higher-level management systems, fostering a connected and intelligent operational environment.

The KD2, while similar in many aspects, offers more compact dimensions and is tailored for applications where space conservation is critical. It retains the essential features of the KD20 but prioritizes simplicity and efficiency, making it ideal for smaller setups or less complex processes. Its robust construction ensures reliability in demanding environments, withstanding temperature fluctuations and other challenging conditions.

Both models utilize Emerson’s proprietary control algorithms, which incorporate advanced methodologies like PID control and adaptive tuning. These algorithms optimize process control, ensuring consistency and accuracy in output, which is crucial for maintaining product quality and minimizing waste.

Furthermore, the KD series includes advanced diagnostic capabilities that provide valuable insights into system performance. These diagnostic tools help in predictive maintenance by identifying issues before they escalate, thereby reducing downtime and operational costs.
