In case of a restart disable state, the text RESTART DISABLE will appear on the
display. The state will not affect the disable/alarm and trip LEDs, but instead you
can use a programmable LED to indicate the state; refer to section Programmable
target LEDs. The text message for the restart disable state is non-latching, whereas
the status target via a programmable LED can be either latching or non-latching.
The restart of a motor can be disabled by the thermal protection, the cumulative
start-up time counter or an external digital input signal. For the priority of targets for
the restart disable state; refer to section Priority of operation target messages.
