MAXIMUM STARTING RATE
The element can be programmed to perform classical monitoring function of Starts Per Hour. However, time interval units
specified by the
START/HR TIME INTERVAL
setting are in minutes for increased flexibility. The
STARTS/HR MAX NUMBER OF
STARTS
setting specifies start attempt number limit during the interval. The time unit and ranges accommodate the starting
requirements of large direct-on-line motors.
The element asserts the following three FlexLogic operands:
•
The
STARTS-PER-HOUR PKP
operand indicates that the maximum permitted starting rate has been reached. When
stopped, the motor should not be restarted until the lockout time elapses.
•
The
STARTS-PER-HOUR OP
operand indicates the motor stopped when the maximum permitted starting rate has been
already reached. This operand should be used to inhibit the start command.
•
The
STARTS-PER-HOUR DPO
operand indicates that the maximum permitted starting rate has not been reached. When
stopped, the motor could be restarted immediately.
The element uses motor status asserted by the Thermal Model element. The thermal protection must be configured prop-
erly in order for this function to operate.
