start the motor during this time. To prevent motor starts during the backspin period,
enter a time in minutes in the Antibackspin Starting Delay setting. If the relay trips or
the motor is stopped, the relay will generate a trip signal and maintain it for at least this
amount of time. The relay will not issue a start during the antibackspin period.
The Emergency Restart function overrides the Antibackspin function allowing the
motor to be placed back in service in an emergency.
Factory Logic Settings
Table 4.38 Fact ory Logic Setti ngs
The SEL-701 Relay includes factory logic settings that generate trip and alarm
outputs for the protection elements shown in Figure 4.5 on page 4.47 through
Figure 4.8 on page 4.49. The elements shown in Figure 4.5 on page 4.47 and
Figure 4.6 on page 4.48 only cause a trip or alarm if you have enabled them through
settings described throughout this section. If the tripping, alarm, and control input logic
shown in Figure 4.5 on page 4.47 through Figure 4.8 on page 4.49 are acceptable for
your application, set Use Factory Logic Settings equal to Y.
Appendix B: SELogic® Control Equations & Relay Logic describes powerful,
flexible logic that allows you to customize the tripping, input, and output contact
performance. If you wish to change the performance shown in Figure 4.5 on page 4.47
through Figure 4.8 on page 4.49, set Use Factory Logic Settings equal to N. The relay
will present additional logic settings that you can modify to customize the relay
performance for your application.
