P.054 Level Sense Start Enable

(continued)

As a safety precaution, Reliance Electric recommends that the user provide an
audible or visual alarm to indicate that this feature is enabled and the motor may
start when power is applied to the drive. The user should also post warnings on the
motor, the drive, and any other applicable equipment to alert personnel that the
application uses an automatic start-up feature.

Figure 4.8 shows an example of a typical circuit that can be used on 1 to 20 HP
drives. This circuit will energize an alarm device prior to motor start up.

Note that if P.000 =rE, the terminal strip LOC/REM switch determines the control
source (local or remote) at power up.
