2.7.2ATS Control Sequence of Operation

See Figure 2-8 for time delay settings.

Normal Source Fails:

1.The load control contact opens.

2.The engine start time delay times out.

3.The generator set is signaled to start.

4.The generator starts and the emergency source becomes available.

5.The normal-to-emergency time delay times out.

6.The transfer switch transfers to the emergency source.

7.The load control contact time delay times out.

8.The load control contact closes.

Normal Source Returns:

1.The emergency-to-normal time delay times out.

2.The contactor transfers to the normal source.

3.The engine cooldown time delay times out.

4.The generator is signaled to stop.

2.7.3Time Delays

Time delays are factory-set to the values shown in Figure 2-8. An authorized distributor/dealer can adjust time delays using a personal computer and Kohlerr SiteTecht software.

Time delays described in this section operate only when the controller is connected to a Kohlerr Model RXT transfer switch.

The engine start and load transfer time delays prevent engine start and load transfer caused by brief variations in the utility power source.

2.7.4ATS Load Control Relay Time Delay

The load control time delay allows delayed starting of large motor loads (such as air conditioners), preventing simultaneous starting of large motors after transfer to the generator set. The load control time delay is fixed at 5 minutes. It is not adjustable.

The load must be connected to the load control output on the interface board of the Model RXT transfer switch. See the transfer switch operation and installation manual for connection instructions.

Time Delay

Setting

Description

 

 

 

Engine Start

3 seconds

Time delay after utility source is lost until the engine start cycle begins.

 

 

Guards against starting the generator set because of a brief change in

 

 

the utility source.

 

 

 

Transfer, Normal to Emergency

3 seconds

Time delay after emergency source becomes available until transfer to

 

 

emergency source.

 

 

 

Transfer, Emergency to Normal

2 minutes

Time delay after the utility source returns until transfer back to normal.

 

 

Ensures that the the utility source is stable before transferring from the

 

 

emergency source.

 

 

 

Load Control

5 minutes

See Section 2.7.4. Allows delayed connection of selected loads to the

 

 

generator set to prevent simultaneous starting of large motors after

 

 

transfer to the emergency source. Recommended for delayed starting

 

 

of air conditioners.

Liquid-cooled engines are known for their ability to provide better thermal management, thereby extending the life of the engine while also improving efficiency. Moreover, the Kohler 24RCL utilizes a proven design that enables quick starts and reliable operation, even in the most challenging conditions.

Another key technology in the 24RCL is its integrated transfer switch, which automatically detects power outages and switches the home’s electrical supply to the generator. This seamless transition ensures that there is no disruption in power, making it an ideal solution for critical loads such as refrigerators, medical equipment, and security systems. The generator’s advanced control system allows for easy monitoring and maintenance, providing users with peace of mind whenever they rely on their backup power.

The Kohler 24RCL boasts a weather-resistant enclosure, designed to withstand the elements and provide protection against rain, snow, and harsh winds. This rugged construction also contributes to the longevity of the unit, ensuring that it can perform reliably year after year.

Sustainability is another driving factor in the design of the Kohler 24RCL. The generator features efficient fuel consumption, which not only helps to reduce operating costs but also minimizes the environmental impact. With many homeowners increasingly focused on eco-friendly solutions, the 24RCL fits seamlessly into a sustainable lifestyle.

Overall, the Kohler 24RCL is a powerful, efficient, and quiet backup generator that combines advanced technology with rugged reliability. Its features make it a standout choice for homeowners seeking a dependable power solution that prioritizes convenience, safety, and sustainability. Whether facing severe weather or unexpected outages, the Kohler 24RCL ensures that homes remain powered and protected.
