Description

Operation

The ATS-10 provides the mains voltage monitoring and automatic transfer switching. In the event of a mains voltage failure, the remote start relay output is energized and the unit automatically transfers the load from the mains to the generator. Microprocessor technology allows exact measurement, set point adjustment and timing functions with the parameters to be simply programmed and displayed from the front panel.

The ATS-10 automatic transfer switch can detect failure of any phase of the mains supply. If at least one of the mains phase voltages goes outside set limits, the unit operates as follows:

- The Mains Voltage Okay led turns from green to red. The mains contactor output is deenergized and the green Mains Contactor Closed led is extinguished.

- The remote start output is energised after the Remote Start Delay parameter has expired. The generatorstart module receives this signal and initiates the engine start.

- If the Unit Usage Type parameter (P00) is selected as 0 (Type-1); When the generator voltage is within set limits, the yellow Generator Running led will illuminate. The unit will allow the generating set to run without load until the Engine Heating Period parameter is expired. After this time,

If the Unit Usage Type parameter (P00) is selected as 1 (Type-2); When the Engine running signal is present, the yellow Generator Running led will illuminate. The unit will allow the generating set to run without load until the Load gen. signal is present. If this signal is present,

- The generator contactor output will be energized a when the Generator Contactor Delay parameter is expired.

- If the mains voltage return to within limits, the Mains Voltage Okay led will turn to green and the unit waits for the Mains Return delay parameter for the mains voltage stabilization.

- When the Mains Return Delay parameter is expired, the yellow Generator Contactor Closed led is extinguished and the generator contactor output is deenergized. Then the green Mains Contactor Closed led will start blinking and then the unit will wait for the Mains contactor Delay parameter.

- When the Mains contactor Delay parameter is expired, the green Mains Contactor Closed led will illuminate steadily and the mains contactor output is energized. Then the remote start output is deenergized.

- The unit is ready for a new mains failure.

The ATS-10 has got a TEST mode feature. This mode allows the generating set to be tested without taking the load. This mode is also called Emergency backup mode which keeps the generating set running and makes a quick transfer if a mains failure occurs.In this mode, The remote start output will be energized but no load transfer will take place unless the occurrence of a mains failure. If a mains failure occurs, the load will be transferred to the generating set. If the mains voltage return to within limits and the Mains Return Delay parameter is expired, the load will be transferred to the mains, but the generating set will be kept running. The remote start output will only deenergized when the Test mode is cancelled.
