  • Page 3: Microvission Installation Recommendations

    2.0 MicroVission Installation Recommendations These instructions are designed to help you perform the safe removal of your current controller and the instal- lation the MicroVission controller as replacement. WARNING WARNING Ensure power/control switches are in the off position After stopping the compressor, allow the compressor and all power are disconnected.

  • Page 4: Figure 2. Keypad Ul Retrofit

    NOTE NOTE Torque all hardware according to specifi cations, see If excesive vibration occurs, further support from the Table 1 at the end of this guide controller bracket to the base may be required NOTE The UL version of the Keypad Micro is wider and requires additional cross supports.

    Step 4. Mount the vibration isolators on the mounting brackets and bolt the MicroVission panel to the isolators using the hardware in KT1133A1 (see Figure 3). Figure 3. MicroVission Panel on Support Bracket Step 5. Remove the existing pressure transducers and RTD’s and replace RTD wells as needed. Install the five new transducers and three new RTD’s from instrumentation and process kits (see Table 2) and wire to the MicroVission using the cords and cord grips in the kit.

  • Page 7: Installation When Retrofitting From Pressure Switches

    2.2 Installation when retrofitting from pressure switches The mounting position of the MicroVission controller will depend on the type of drive your compressor uses, see Figure 7 for reference. Figure 7. Belt Drive and Direct Drive mounting Step 1. Shut Off the 120V power to the compressor controls and isolate the compressor by shutting Off all service valves and lock out per plant procedure.

    Step 4. Mount the MicroVission bracket to the compressor frame with four (4) 3/4” bolts and hardware provided. If the compressor base is filled with concrete the bracket can be welded to the compressor frame. Follow standard practices for welding and fabrication procedures. WARNING NOTE When handling microcontroller, use additional...
