function, the trip signal will remain until the motor
thermal estimate has cooled or time has passed

Antibackspin Setting
Table 4.38
Antibackspin Setting
In certain pump applications, fluid flowing
backward through the pump may spin the pump
motor for a short time after the motor is stopped.
It is dangerous to attempt to 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 4.39
Factory Logic Settings
The SIMPRO-100 Relay includes factory logic
settings that generate trip and alarm outputs for
the protection elements shown in Figure 4.5,
page 69 – Figure 4.8, page 70. The elements
shown in Figure 4.5, page 69 and Figure 4.6,
page 69 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, page 69 –
Figure 4.8, page 70 are acceptable for your
application, set Use Factory Logic Settings equal
to Y.
Appendix B, page 137 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, page 69 – Figure 4.8, page 70, 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.
