For most Relay Functions, setpoint values represent material levels, entered in Units
(P005) or percent of Span (P007) as referenced to Empty (P006). Temperature alarm
values are entered in degrees Celsius (°C).
Rate alarms are entered in Units/minute or percent of Span per minute. A positive value is
entered for a filling rate alarm, negative for emptying.
