User Setting for Voltage & Frequency

Standard 3-Phase Sensing on 3 and 4 Pole Units

Source 1

Under Voltage "Restore"

Factory Default: 90%

This adjustment determines the minimum acceptable voltage required to transfer to Source 1.

Adjust via the SET menu. Range is 85% to 100% in 1% increments (see page 17).

Once satisfied, the T timer will begin timing to transfer to Source 1.

Under Voltage "Fail"

Factory Default: 80%

This adjustment determines the low voltage threshold. Adjust via the SET menu. Range is 75% to 98% in 1% increments (see page 17).

"Fail" must be a minimum of 2 % below "Restore" setting. Once voltage falls below threshold, P timer begins timing to signal Source 2 Generator to start.

Under Frequency "Restore"

Factory Default: 95%

This adjustment determines the minimum acceptable frequency required to transfer to Source 1.

Adjust via the SET menu. Range is 90% to 100% in 1% increments (see page 17).

Once satisfied, the T timer will begin timing to transfer to Source 1.

Under Frequency "Fail"

Factory Default: 90%, (5 seconds minimum).

This adjustment determines the low frequency threshold. Adjust via the SET menu. Range is 88% to 98% in 1% increments (see page 17).

"Fail" must be a minimum of 2 % below "Restore" setting. Once satisfied, the T timer will begin timing to transfer to Source 1.

Over Frequency "Restore"

Factory Default: 102%

This adjustment determines the minimum acceptable Over Frequency threshold at which the transfer switch is allowed to re-transfer to Source 1.

Adjust via the SET menu. Range is 102% to 104% in 1% increments (see page 17). “Restore” must be a minimum of 1% below “Fail” setting.

Over Frequency "Fail"

Factory Default: 105%

This adjustment determines the maximum acceptable Over Frequency.

Adjust via the SET menu. Range is 103% to 105% in 1% increments (see page 17).Once exceeded, the P timer begins timing to signal the generator to start.

Source 2

Under Voltage "Restore"

Factory Default: 90%

This adjustment determines the minimum acceptable voltage required to transfer to Source 2.

Adjust via the SET menu. Range is 85% to 100% in 1% increments (see page 17).

Once satisfied, the W timer will begin timing to transfer to Source 2.

Under Voltage "Fail"

Factory Default: 80%

This adjustment determines the low voltage threshold. Adjust via the SET menu. Range is 75% to 98% in 1% increments (see page 17).

"Fail" must be a minimum of 2 % below "Restore" setting. Once voltage falls below threshold, T timer will be bypassed to expedite the transfer to Source 1.

Over Voltage "Fail"

Factory Default: 110%

This adjustment determines the maximum acceptable Over Voltage. Adjust via the SET menu. Range is 105% to 110% in 1% increments (see page 17). Once exceed- ed, the T timer will be bypassed to expedite the transfer to Source 1.

Over Voltage "Restore"

Factory Default: 105%

This adjustment determines the minimum acceptable Over Voltage threshold at which the transfer switch is allowed to transfer to Source 2. Adjust via the SET menu. Range is 103% to 105% in 1% increments (see page 17). “Restore” must be a minimum of

2% below “Fail” setting.

Under Frequency "Restore"

Factory Default: 95%

This adjustment determines the minimum acceptable frequency required to transfer to Source 2.

Adjust via the SET menu. Range is 90% to 100% in 1% increments (see page 17).

Once satisfied, the W timer will begin timing to transfer to Source 2.

Under Frequency "Fail"

Factory Default: 90%, (5 seconds minimum).

This adjustment determines the low frequency threshold. Adjust via the SET menu. Range is 88% to 98% in 1% increments (see page 17).

"Fail" must be a minimum of 2 % below "Restore" setting. Once satisfied, the W timer will begin timing to transfer to Source 2.

Over Frequency "Fail"

Factory Default: 105%

This adjustment determines the maximum acceptable Over Frequency. Adjust via the SET menu. Range is 103% to 105% in 1% increments (see page 17). Once exceeded, the T timer will be bypassed to expedite the transfer to Source 1.

Over Frequency "Restore"

Factory Default: 102%

This adjustment determines the minimum acceptable Over Frequency threshold at which the transfer switch is allowed to re-transfer to Source 2. Adjust via the SET menu. Range is 102% to 104% in 1% increments (see page 17). “Restore” must be a minimum of

1% below “Fail” setting.

ZBTS, ZBTSD specifications

General Electric (GE) has established itself as a leader in the field of industrial automation and control systems, with its ZBTSD and ZBTS series representing some of the most advanced technology available. These systems are engineered to enhance performance, efficiency, and reliability in various industrial applications.

The ZBTSD, or Zero-Based Time Series Data, is designed to optimize data storage and retrieval processes. One of its main features is its ability to provide real-time monitoring and analytics of dynamic processes. This capability is crucial for industries that require immediate insights into their operations, helping to minimize downtime and enhance decision-making. The ZBTSD utilizes advanced machine learning algorithms to identify trends and patterns, enabling predictive maintenance that can significantly reduce operational costs.

On the other hand, the ZBTS, or Zero-Based Time Series Solutions, focuses on delivering comprehensive solutions for time series data management. This system is adept at handling vast amounts of data generated by industrial equipment, ensuring that organizations can efficiently process and analyze this information. Key characteristics of ZBTS include scalability, which allows companies to expand their systems as their data grows, and flexibility, permitting integration with various data sources.

One notable technology employed in both ZBTSD and ZBTS is cloud computing. By leveraging the cloud, these systems offer enhanced data accessibility and collaboration capabilities. Users can access critical data anytime, anywhere, facilitating timely responses to operational challenges.
