7.9.4.4
Setting independent fail-safe controls
Independent fail-safe controls allow you to vary an individual relay from the global failsafe
controls programmed in:
●
Material Level (2.4.5.) (Page 178)
●
LOE Timer (2.4.2.) (Page 177)
●
Fail-safe Advance (2.4.6.) (Page 179)
Example:
The global fail-safe controls are set to hold, and Relay 5 is set to trigger an alarm bell.

7.9.4.5
Setting a pump to Run-ON
When you need to pump below the normal OFF setpoint, use Run-ON Interval (2.8.2.7.1.)
(Page 205) and Run-ON Duration (2.8.2.7.3.) (Page 206) to control this event.
Example:
The pump connected to Relay 3 is set to pump for an extra 60 seconds every 5 hours.

Time in hours of Run-ON interval.
(Page 206)
3
60
Run-ON for 60 seconds.
Note
Run-ON Interval (2.8.2.7.1.) (Page 205) counts when the indexed relay is tripped, not the
number of pump cycles. If the indexed relay only trips once every four pump cycles, then the
actual interval of the run-ON will be 20 pump cycles, or five cycles of Relay 3.
Note
Setting a value in Run-ON Duration (2.8.2.7.3.) (Page 206) enables run-on for that relay. The
default value of 0.0 seconds disables run-on. Any relay with a pump duration value other
than 0.0 seconds will use the value from the highest indexed relay in the pump group set in
Pump Group (2.8.2.2.). (Page 201)
