CON0
•
OUT (Setpoint from Loop 1 to Loop 3) (Cont)
C106 5-9 CON0 Proportional Band - Is the percent of error required to move
the CON0
•
OUT full scale for proportional action.
100
C107 5-9 CON0 Reset Time - Is the number of minutes per repeat of integral
action. It is mutually exclusive with Manual Reset. 0
C108 5-9 CON0 Rate Time - Represents the minutes proportional action is
advanced. 0
C111 5-9 CON0 Manual Reset - It determines output valve position when the
controller Loop 1 is in Auto and the error = 0. It is mutually
exclusive with Reset Time. 50
C115 5-9 CON0 Controller Span - Enter a value, that when added to the
Loop 1 Control Lower Range value, will produce the Control
upper range value in engineering units. 100
C116 5-9 CON0 Controller Lower Range - Enter a value that represents in
engineering units the Loop 1 Control lower range value. 0
C118 5-9 CON0 Output Slew Rate - It is a rate limit applied to the output
value (setpoint from Loop 1 to Loop 3). When configured to
a non-zero value, the output from the Loop 1 Auto-Selector is
only allowed to change by this amount each scan time. A
zero disables output slewing. It does not affect manual
operation. 0
AO0 - #1 Secondary Control Output (Loop 3)
L472 5-5 AO0 0-20 mA Output - 0 = 4-20 mA signal; 1 = 0-20 mA signal.
Enter a value to match the Loop 3 output valve requirements. 0
L168 5-9 CON2 Manual Fallback Disable - 0 = always power up Loop 3 in
manual; 1 = auto/manual selector unchanged at power up. 0
L170 5-9 CON2 Hard Manual Limit - 1 = apply output limits to the final output
of the Loop 3 Auto-Manual Generator. Affects both the
manual push buttons and the controller’s result. 0 = do not
apply limits. 1
C181 5-9 CON2 Output High Limit - Sets maximum Loop 3 output signal
value in engineering units. 100
C182 5-9 CON2 Output Low Limit - Sets minimum Loop 3 output signal value
in engineering units. 0
C190 5-9 CON2 Output Slew Rate - It is a rate limit applied to the output
value. When configured to a non-zero value, the output from
the Loop 3 Auto-Selector is only allowed to change by this
amount each scan time. A zero disables output slewing. It
does not affect manual operation. 0
CON 2 #1 Secondary Control Output (LOOP 3) Related Datapoints
C178 5-9 CON2 Proportional Band - Is the percent of error required to move
the Loop 3 output full scale for proportional action. 100
C179 5-9 CON2 Reset Time - Is the number of minutes per repeat of integral
action. It is mutually exclusive with Manual Reset. 0
C180 5-9 CON2 Rate Time - Represents the minutes proportional action is
advanced. 0
