SERVICE

WARNING

DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait five (5) minutes for the DC bus capacitors to discharge and then check the voltage with a voltmeter to ensure the DC bus capacitors are discharged before touch- ing any internal components. Failure to observe this pre- caution could result in severe bodily injury or loss of life.

Troubleshooting the Drive — The drive can display two kinds of error codes on the ICVC called the Alert and Alarm codes. These codes signal a problem detected during self tuning or drive operation. Alert and Alarm codes are locat- ed in the 19XRV Start-Up, Operation and Maintenance Instruc- tions. Note the following differences between Carrier and Allen-Bradley terminology:

•A warning message on the ICVC is an ALERT.

•The same warning viewed with Rockwell Drive Explorer is a VFD ALARM.

•A failure resulting in a shutdown is seen as an ALARM on the ICVC and as a VFD FAULT when viewed with Drive Explorer.

See Tables 3-6 and Fig. 12.

ICVC ALERT CODES — An alert condition is indicated by a message at the top of the ICVC default screen. In addition, an exclamation point (!) will appear next to any affected point on an ICVC display screen. The drive will continue to operate during the alert condition. Investigate the cause of the alert to ensure it does not lead to a fault condition. The alert code will automatically be cleared from the ICVC when the condition causing the alert no longer exists. See Table 4.

ICVC ALARM CODES — An alarm condition is also indi- cated by a message at the top of the ICVC default screen. If an alarm occurs, the drive coasts to stop. The STS (status) light on the drive will turn from Green to Red or Yellow (see Table 3). The detected fault message is maintained on the display until it is cleared by pressing the RESET softkey. See Table 5.

TEST EQUIPMENT NEEDED TO TROUBLESHOOT — An isolated multimeter adequately rated for the DC bus volt- age will be needed to measure DC bus voltage and to make resistance checks. Note that dedicated troubleshooting test points are not provided.

19XRV specifications

The Carrier 19XRV is a cutting-edge rooftop chiller designed to provide reliable and efficient cooling solutions for a wide range of applications, including commercial buildings and industrial facilities. This advanced system integrates the latest technologies and innovative features to ensure optimal performance, energy efficiency, and ease of use.

One of the most prominent features of the 19XRV is its advanced inverter-driven compressor technology. This allows the chiller to adjust its capacity seamlessly based on the building's cooling demand. By varying the speed of the compressor, the 19XRV maximizes energy efficiency and minimizes operational costs, especially during partial load conditions. This capability not only enhances comfort but also contributes to reduced energy consumption, making it a sustainable choice for environmentally conscious users.

In addition to the inverter technology, the 19XRV incorporates a microchannel coil design. This design optimizes heat exchange efficiency and reduces the refrigerant charge, which is an essential factor in lowering greenhouse gas emissions. The microchannel coils also allow for more compact dimensions, making installation easier and maximizing rooftop space usage.

Another significant aspect of the Carrier 19XRV is its robust controls system. Equipped with Carrier’s advanced ComfortLink™ controls, this chiller offers precise monitoring and control over its operation. Users can easily integrate the chiller into building management systems for real-time data access and efficiency analytics. This connectivity ensures that operators can make informed decisions to optimize performance continuously.

The 19XRV also includes features aimed at enhancing reliability and durability. Its structural design incorporates corrosion-resistant materials, allowing the unit to withstand harsh environmental conditions. This reliability translates to lower maintenance requirements and extended equipment lifespan, providing excellent value over time.

Moreover, the chiller is designed for quiet operation, making it suitable for applications where low noise levels are essential. Sound-dampening measures ensure that the 19XRV can be utilized in urban environments or near sensitive areas without causing disturbances.

In conclusion, the Carrier 19XRV is a state-of-the-art rooftop chiller that combines efficiency, technology, and durability.
