Total operation time displays the hours of operation after initialization at factory.
Upper row " $$$$$$ " describes cause of ALARM / TRIP.
Lower row " $$$$$$ " shows value of parameter that caused ALARM / TRIP.
Display defaults to No. 2 (Motor Current) when buttons on LCD controller are not operated
for one minute.
"DISP. SELECT" scrolls the display in order. It will display progressively all present
ALARM/TRIP’s.
