Failsafe Mode
The FM approved Form C relay operates in a failsafe mode. During powerup, the relay is off and can be selected to restart either manually or automatically. In normal operation when an alarm occurs and the relay resets, the process can be restarted by

operator actions as prescribed by process and configuration conditions. In order to restart, the process must return within setpoint AND the operator must acknowledge the process either by the front panel, digital input or serial link.
