• Feeder Control Function (refer to Figure 19 and Figure 20)
Option Description
Phase Defines the relay status if the process value exceeds the
setpoint.
High (default)—turns the relay on when the process value
exceeds the setpoint.
Low—turns the relay on when the process value falls
below the setpoint.
Set setpoint Sets the process value at which the relay toggles. The
default value is different for each sensor.
Deadband Sets the area for an amount of change necessary after the
relay setpoint is reached in order to satisfy a condition.
Overfeed timer Sets a time period for de-activating an active relay if the
process setpoint cannot be reached. Once an overfeed
alarm is present, it must be manually reset.
Off delay Sets a delay time for the relay to turn off (default:
0 seconds).
On delay Sets a delay time for the relay to turn on (default:
0 seconds).
