Incomplete Sequence Report Back Time (INSQ)
The incomplete sequence function requires an input from the report back contact from the process that the motor is
running. Shortly after the motor starts, the report back contact provides an indication that the process has started to
operate as expected. If the process does not start up correctly, the contact does not close within the expected time. If
a problem develops later on, the report back contact opens. In either case, the open contact state indicates that the
motor should be tripped.
To use this function, set a time limit for report back here and define the start of report back timing. Connect the report
back contact to one of the protective device Discrete Inputs. If this input is not energized before the set time expires,
the relay will trip on an “Incomplete Sequence”.
Note that the input must be energized continuously after the time delay has expired to hold off this trip. Otherwise, if the
incomplete sequence report back contact changes state for a period greater than 0.5 seconds, the relay will trip on an
incomplete sequence. This delay allows for any momentary transient switching that may occur in the process report
back contact, such as that which can occur in an open transition reduced voltage start.
