When a contact closure is seen across Digital Input #4 (MI4) and DC Common (DCM), the fan is pre-programmed to issue a base-block
code and initiate fan shutdown. This is essentially turning off the fan controller's output terminals, while leaving the fan controller in Run
mode.
Auxiliary contacts can be associated with basic timers and thermostats, as well as equipment such as overhead cranes, in order to
initiate fan shutdown simultaneously with equipment shutdown when contact closure is seen.
After the auxiliary contact has reopened, the fan will return to its previous operating mode.
