Independent Relay Setpoints

Relay ON and OFF Setpoint values set the critical points (based on the Relay Function)
where, in RUN mode:
• Relay status indicators are switched ON and OFF
• Alarm Indicators (if programmed) are switched ON or OFF
• Relays are energized and de-energized
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.
