generator.

8.Turn ON electrical loads. Apply an electrical load equal to the full rated wattage/amperage capacity of the installed generator.

9.Connect an accurate AC frequency meter across terminal lugs . Voltage should be +/- 1.5% of the specificated, and frequency +/- 4.0% of the specificated on the unit.

10.Let the generator run at full rated load for 20-30 min- utes. Listen for unusual noises, vibration or other indica- tions of abnormal operation. Check for oil leaks, evidence of overheating, etc.

11.When testing under load is complete, turn OFF electrical loads.

12.Set the generator's main circuit breakers to their OFF (or open) positions.

13.Let the engine run at no-load for a few minutes.

14.Set the Start/stop switch to stop. The engine should shut down.

6.3. CHECKING AUTOMATIC OPERATION

To check the system for proper automatic operation, pro- ceed as follows:

1.Check that the Start/stop switch is set to stop.

2.Manually set the transfer switch to the UTILITY position, i.e., load terminals connected to the utility power source side.

3.Turn ON the utility power supply to the transfer switch, using the means provided (such as a utility main line circuit breaker).

4.Set the Start/stop switch to manual. The engine should crank and start when the remote start input is activated.

5.Turn OFF the utility power supply to the transfer switch.

With the Start/stop switch at AUTO, the engine should crank and start when the utility source power is turned OFF. After starting, the transfer switch should connect load circuits to the standby side. Let the system go through its entire auto- matic sequence of operation.

With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur:

•After about six seconds, the switch should transfer loads back to the utility power source.

•About one minute after retransfer, the engine should shut down.

Check the installation and application data charts for any additional information.

ACUM210, ACUM110, ACUM65, ACUM185, ACUM140 specifications

Armstrong World Industries has established itself as a leader in the design and manufacture of innovative ceiling and wall solutions. Among their notable acoustic ceiling offerings are the ACUM84, ACUM210, ACUM65, ACUM140, and ACUM185 tiles. Each of these products is engineered with distinct features and technologies aimed at enhancing acoustic performance, durability, and aesthetics in various commercial spaces.

The ACUM84 is designed for spaces that prioritize sound absorption and overall acoustic quality. It utilizes advanced sound-dampening technology, making it suitable for environments such as offices, schools, and healthcare facilities. This tile achieves a high Noise Reduction Coefficient (NRC), effectively minimizing sound reverberation, which is essential for maintaining concentration in busy settings.

Similarly, the ACUM210 offers enhanced acoustic properties but with a focus on durability. This tile is constructed with a robust material that is resistant to impact and moisture, making it an excellent choice for high-traffic areas. The fabric-like texture not only adds aesthetic value but also improves its sound-absorbing capabilities, contributing to a quieter environment.

For those seeking a versatile solution, the ACUM65 is an ideal option. This tile is lightweight yet durable, making installation straightforward. Its ecological design ensures minimal environmental impact while providing superior acoustic performance. The ACUM65 is particularly well-suited for retail spaces, where customer experience can be significantly enhanced by better sound control.

ACUM140 is engineered for flexibility and design versatility. With a range of finishes and colors, it allows architects and designers to incorporate acoustic solutions that harmonize with the overall aesthetic of the space. Its high NRC rating ensures a calm auditory environment, making it an excellent fit for restaurants and auditoriums.

Lastly, the ACUM185 combines aesthetics with functionality, offering a sleek design while maintaining outstanding sound absorption capabilities. It meets the demands of contemporary styling without compromising performance. This tile is particularly favored in corporate environments where aesthetics play a crucial role in branding and employee satisfaction.

In conclusion, Armstrong's ACUM product line, including ACUM84, ACUM210, ACUM65, ACUM140, and ACUM185, showcases technologies and characteristics that cater to a variety of applications. With a strong focus on acoustic management, durability, and design versatility, Armstrong continues to provide innovative solutions tailored to the needs of modern commercial spaces.
