4.3.10.3 - Manual tests

This function allows the user to test the outputs individually, if the machine is completely shut down (LOFF). To carry out a manual test use the arrow keys to access the output to be tested and press the Enter key (longer than 2 seconds) to activate the modification mode. The password is automatically requested, if it has not previously been verified. The Outputs/Test LED on the user interface begins to flash. Enter the desired test value and again press Enter to start the test. 'TESt' is displayed on the 4- digit display alternately with the value tested. The Outputs/Test LED stops flashing. Press the Enter key or an arrow key to stop the test.

4.3.10.4 - Automatic tests

The automatic test function verifies the integrity of the analo- gue entries and activates the outputs in sequence. For each test 't XX' is displayed on the user interface. 'xx' indicates the number of the test in progress. When a test has been completed, the following test is automatically activated.

A message may appear, asking the operator for a validation with the Enter key, if the control cannot automatically verify a sensor value or an output status. If the value read or the output status is incorrect, the operator must press a different key (not the Enter key) to cancel the automatic test procedure.

If a test fails, an error message and an error code are dis- played. The automatic test procedure is interrupted.

When all tests have been completed, an end-of-test message appears.

The table below describes the messages shown on the user interface during the automatic test sequence.

The models are engineered to deliver substantial energy savings, meeting or exceeding the latest ASHRAE and DOE efficiency standards.

A significant aspect of the 30RY and 30RA models is their use of environmentally friendly refrigerants. The 30RYH, for instance, employs R-134a refrigerant, which is designed to minimize ozone depletion while maximizing efficiency. This commitment to sustainability aligns with modern environmental regulations and practices, making these chillers a wise choice for eco-conscious projects.

In terms of control technology, the chiller models come equipped with advanced microprocessor-based controls, providing users with optimal system management and diagnostics. This integrated control system enhances the overall performance and reliability of the chillers, allowing for real-time monitoring and adjustment to ensure peak operational efficiency.

Another key feature is the quiet operation of the 30RY/RYH and 30RA/RH series. Designed with sound attenuation in mind, these units minimize noise pollution, making them suitable for installations in noise-sensitive environments. Additionally, the modular design allows for easy installation and maintenance, reducing downtime and providing flexibility in system design.

Both series also offer robust thermal performance, with the capability to handle a wide range of operating conditions. The chillers excel in terms of cooling capacity, providing solutions for varying thermal loads while maintaining energy efficiency. This adaptability is invaluable for facilities managing seasonal changes in cooling demands.

In summary, the Carrier 30RY/RYH and 30RA/RH chillers represent an ideal blend of efficiency, advanced technology, and eco-friendliness. Their high-performance capabilities, user-friendly controls, and sustainable design make them a top choice for commercial and industrial applications, ensuring dependable cooling solutions for diverse environments.
