Automatic Run Test — The 50BV,XJ unit controls are programmed with an automatic run test that checks connection and operation of major components. To perform the run test:

Verify that the control display (LID device/System Monitor) interface cable is connected to internal jack on main controller; that the fire alarm/shutdown switch input (FSD) has a factory jumper or field input; that Bypass (if installed) is set in the DRIVE position; and that the Local/Off/Remote switch is set to the REMOTE position.

NOTE: When the Local/Off/Remote switch is in the REMOTE position, the controller time schedule is pre-set (from the factory) as unoccupied. This means that the unit will not turn on until the run test is enabled. However, if the controller schedule has already been modified in the field, and the current time of day is occupied, then the supply fan will start. The run test will shut the fan down when it

begins. The run test will complete and then the supply will automatically restart.

NOTE: If the Local/Off/Remote switch is in the OFF posi- tion, it is normal for the red alarm light on the display panel to be lit, indicating that the unit is disabled.

NOTE: If the red light stays on when the switch is moved to REMOTE, or if any other problems occur during the run test, refer to the Troubleshooting section of this manual.

To perform the Run Test:

1.Turn unit power on.

The LID display will show the controller identifica- tion, time and date (Fig. 5):

50XJ064-104 specifications

The Carrier 50XJ064-104 is a high-efficiency rooftop air conditioning system designed to deliver exceptional cooling and heating capabilities for diverse commercial applications. One of the standout features of this model is its robust cooling capacity of 64,000 BTUs, making it suitable for mid to large-sized spaces. The 50XJ064-104 is engineered using advanced technologies to ensure energy efficiency and reliable performance, contributing to reduced operational costs and environmental sustainability.

One of the primary technologies employed in the Carrier 50XJ064-104 is the high-efficiency scroll compressor. This component plays a pivotal role in optimizing energy usage while delivering consistent cooling output. The system also incorporates an economizer that allows for enhanced energy savings by utilizing outdoor air for cooling when conditions are favorable. This not only decreases reliance on the compressor but also improves indoor air quality.

The microprocessor-based controls in the 50XJ064-104 provide precise temperature regulation, ensuring optimal comfort levels in various applications. These controls allow for easy programming and can be integrated into building management systems for centralized oversight. Additionally, the unit features a built-in fault detection and diagnostic system that aids in identifying potential issues before they escalate, minimizing downtime and maintenance costs.

The Carrier 50XJ064-104 is designed with durability in mind. It features a weather-resistant cabinet, designed to withstand harsh outdoor conditions and prolong service life. The high-quality insulation within the unit not only enhances energy efficiency but also minimizes noise levels, making it an ideal choice for urban environments where sound control is critical.

Another important characteristic is its environmentally friendly R-410A refrigerant, which has a lower impact on ozone depletion compared to older refrigerants. This aligns with Carrier's commitment to creating sustainable HVAC solutions that comply with current environmental regulations.

Overall, the Carrier 50XJ064-104 stands out for its combination of efficiency, advanced technologies, and durable construction. Whether for commercial buildings, retail spaces, or industrial applications, this rooftop air conditioning unit is designed to provide reliable performance and comfort year-round.
