The
RESTART DELAY MIN TIME
setting specifies the lockout time before starting the motor after the motor has stopped. The
restart delay element asserts the
RESTART DELAY OP
FlexLogic operand for
RESTART DELAY MIN TIME
after the motor has
stopped. The element uses the motor status asserted by the Thermal Model element. The thermal protection must be
configured properly in order for this function to operate.

SETTINGS
CONTROL ELEMENTS
REDUCED VOLTAGE STARTING
The M60 can control the transition of a motor start from reduced to full voltage. This feature uses motor load and a
supervisory timer to initiate a one second control signal (the
REDUCED VOLT CTRL
operand) that can be used to switch to full
voltage. The feature can also assert a trip signal (the
REDUCED VOLT OP
operand) from the starting logic if the current or
timer transitions do not occur as expected. This transition can be defined as current only, current or timer, or current and
timer.
