This module is designed to start and stop two fans so they run in a lead standby fashion. Only the lead fan runs. If the lead fan fails, then the standby fan operates until the failed fan is cleared. For an air handler application two other outputs to control the speed of the fans. The module monitors the alarm status of the lead fan to determine whether the standby fan needs to operate. This module is implemented as a control activity.
