Default
CON1 Control Related Datapoints
C116 5-9 CON0 Controller Lower Range - Enter a value that represents in
engineering units the Primary Control Lower Range value.
0
C142 5-9 CON1 Proportional Band - Is the percent of error required to move
the output full scale for proportional action.
100
C143 5-9 CON1 Reset Time - Is the number of minutes per repeat of integral
action. It is mutually exclusive with Manual Reset.
0
C144 5-9 CON1 Rate Time - Represents the minutes proportional action is
advanced.
0
C147 5-9 CON1 Manual Reset - It determines the output valve position when
the controller is in Auto and the error = 0. It is mutually
exclusive with Reset Time.

L138 5-9 CON1 Auto Enable - Controller output is from a PID algorithm when
set to 1 and A/M push button is in Auto.
1
C151 5-9 CON1 Controller Span - Enter a value, that when added to the
Limiting Controller Lower Range value, will produce the
control upper range value in engineering units.
100
C152 5-9 CON1 Controller Lower Range - Enter a value that represents in
engineering units the Limiting Control Lower Range value.

AO1 - Override Status
L473 5-5 AO1 0-20 mA Output - 0 = 4-20 mA signal; 1 = 0-20 mA signal.
If left at the default value of 0, then 4 mA = Primary Variable
Loop controls AO0 output and 20 mA = Limiting Variable
Loop controls AO0 output.
If configured to a 1, then 0 mA = Primary Variable Loop
controls AO0 output and 20 mA = Limiting Variable Loop
controls AO0 output.
0
DI0 - Remote Enable Primary
L264 5-6 DI0 Contact Input Invert - Normally, the Primary Variable Loop
Remote Enable is permitted if DI0 is closed (datapoint L115 -
Remote Setpoint Enable is set to 1 by DI0). Set to 1 to
reverse the DI0 condition required to permit the Primary
Variable Loop Remote Enable (DI0 open = Primary Variable
Loop Remote Enable).
0
DI1 - Remote Enable Limiting
L265 5-6 DI1 Contact Input Invert - Normally, the Limiting Variable Loop
Remote Enable is permitted if DI1 is closed (datapoint L139 -
Remote Setpoint Enable is set to 1 by DI1). Set to 1 to
reverse the DI1 condition required to permit the Limiting
Variable Loop Remote Enable (DI1 open = Limiting Variable
Loop Remote Enable).
