Title and Function
AO0 - Backup Control Output (Cont)
Output High Limit - Sets maximum Control Output signal
value in engineering units.
Output Low Limit - Sets minimum Control Output signal value
in engineering units.
Output Slew Rate - It is a rate limit applied to the output
value. When configured to a non-zero value, the output from
the Auto-Selector is only allowed to change by this amount
each scan time. A zero disables output slewing. It does not
affect manual operation.
CON0 Control Related Datapoints
Proportional Band - Is the percent of error required to move
the output full scale for proportional action.
Reset Time - Is the number of minutes per repeat of integral
action. It is mutually exclusive with Manual Reset.
Rate Time - Represents the minutes proportional action is
advanced.
Manual Reset - It determines output valve position when the
controller is in Auto and the error = 0. It is mutually
exclusive with Reset Time.
Reverse Switch - 0 = Control Output ↑ if PV ↑; 1 = Control
Output ↓ if PV ↑.
Auto Enable - Controller output is from the PID algorithm
when set to 1 and A/M push button is in Auto.
Controller Span - Enter a value, that when added to the
Controller Lower Range value, will produce the control upper
range value in engineering units.
Controller Lower Range - Enter a value that represents in
engineering units the control lower range value.
AO1 - Computer Control Status
0-20 mA Output - 20 mA indicates computer control; 4 mA
indicates 53MC5000 control.
DI0 - Computer Ready
Contact Input Invert - Normally, Computer Ready is enabled
if DI0 is closed. Set to 1 to reverse the required DI0
condition (DI0 open = Computer Ready) so that the computer
can drive the final element.
DI1 - Auto Enable
Contact Input Invert - Normally, Auto Enable is permitted if
DI0 is closed. Set to 1 to reverse the DI1 condition required
to permit Auto Enable (DI1 open = Auto Enable).
DO0 - Computer Output Diverter
When open, the computer output path is through the diverter
circuit diode to the final element. It is always in an opposite
state from DO1. (Not configurable.)
