Level Controller Configuration
Set Mode Shed Options
(Failure Condition)
See page 3-9 for details about Mode Shed.
Shed Action Shed Action selects whether the controller remains at its present value
(hold output) or goes to the shed output value if the Level Controller
determines that the level measurement has failed.
Factory Default: Go to shed output
Valid Options: Hold output, go to shed output
.
Shed Output This selection sets the control output value during a mode shed action.
If the Level Controller determines that the level measurement is bad,
AND the Mode Shed Action is set to “go to shed output,” the Level
Controller will then automatically set the control output to this value.
This value is entered as a percentage of controller output. For example,
a mode shed output value of 25% corresponds to 8 mA.
(25% 3 (20 – 4 mA) + 4 mA = 8 mA)
Factory Default: 0%
Valid Range: –2.5 to 112.5% (3.6 to 22 mA)
Shed Return This selection determines whether the controller returns from the mode
shed routine if the failed level measurement condition ends.
Factory Default: Return
Valid Options: Return, no return
Set Manual Output
Manual Rate Limit Output rate limits define the maximum rate of change of the control
output when the controller is in manual mode. Setting this variable to
0.0 disables manual output rate limits.
Factory Default: 0.0 (No rate limit)
Valid Range: >
0.0% per second
Manual Output Setting manual output is a two step process. First, set the target mode
to manual (MAN). Second, set the manual output value.
When in manual output mode, the operator enters a value as a
percentage of controller output. For example, a manual output
value of 25% corresponds to 8 mA.
(25% 3 (20 – 4 mA) + 4 mA = 8 mA)
Valid Range: –0.625 to 105% (3.9 to 20.8 mA)
