P.054 Level Sense Start Enable

(continued)

Figure 4.8 shows an example of a typical circuit that can be used on LiquiFlo 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.

!

ATTENTION: As a safety precaution, Reliance Electric recommends
that you provide an audible or visual alarm to indicate that this feature is
enabled and the motor can start when power is applied to the drive. You
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. Failure to observe this precaution could result
in severe bodily injury or loss of life.
