FIGURE 5. TB2 CONNECTIONS FOR TRANSFER INHIBIT

This feature is used to control load transfer to generator sets. When enabled, load transfer will not take

place unless the Override pushbutton on the control panel is pressed or the transfer inhibit input is

disabled.

Pressing the Override pushbutton on the control panel bypasses the transfer inhibit input and bypasses

TDNE. The TDNE runs if the transfer inhibit input is disabled.

3.4.1.3 Retransfer Inhibit

A retransfer inhibit input is set up by connecting a dry (voltage free) contact between TB2-7 and TB2-8.

Closing the contact enables the feature and opening the contact disables it.

This feature is used to prevent the ATS from automatically transferring the load back to the utility. When

enabled, load transfer will not take place unless the Override pushbutton on the control panel is pressed,

the retransfer inhibit input is disabled, or the genset fails. If the genset fails, retransfer inhibit is ignored.

Pressing the Override pushbutton on the control panel bypasses the retransfer inhibit input and bypasses

the TDEN. The TDNE runs if the retransfer inhibit input is disabled.
