Parameter Initialize / Lock - Larsen & Toubro C*2000 Series User Manual

Chapter 8 Application
0: continuous operation when cooling fan trip occurs.

-. Operation is not stopped regardless of cooling fan trip.
-.When I55 is set to 18 (cooling fan fault alarm), fault alarm signal can be output using Multi-function
relay.
If operation is continued after cooling fan trip occurs, Overheat trip may happen and
protective function be activated. It also reduces the life of main components due to rise in
inverter inner temperature.
 1: operation stopped at cooling fan fault
-.when cooling fan fault occurs,
stopped.
-. If I55 is set to 17(Fault output), fault message is displayed.
