Micromod Micro-DCI: 53MC5000 Multi-Loop Process Controller Installation - Manual (Page 79)

2. With the 53MC5000 still in "Suspend mode" (B00=0), load the FDC set-up values for CS20
Standard Two Loop PID from the EPROM into controller RAM. This is done by setting B16=20.
Other values in B16 will load other strategy types. B16 will always reset to 0 when the load is com-
plete.
3. After loading the CS20 Two Loop PID database values, set B00=1. This places the 53MC5000 in
a "Run" mode using the FCS strategy.
At this point, the 53MC5000 is a functional controller with default spans and turning parameters.
The user may configure parameters specific to an application as described below.
4. Configure the PV input signal parameters for Loop #1:
•
Set-up the AI module by entering the span (in Engineering Units of the PV range) in
C256 and the range minimum in C276. Span is defined as (Range Max. - Range
Min.)
•
Set-up the CON module by entering the span in C115 and the range minimum in
C116. For standard PID control, the span and minimum of the AI and CON modules
are the same.
•
The 53MC5000 is set to accept a 1 - 5 V PV signal. If 0 - 5 V is required, enter
L416=1.
•
The 53MC5000 is set to accept a linear PV signal. If square root extraction is
required, enter L440=1.
5. Configure the PV input signal parameters for Loop #2:
•
Set-up the AI module by entering the span (in Engineering Units of the PV range) in
C257 and the range minimum in C277. Span is defined as (Range Max. - Range
Min.).
•
Set-up the CON module by entering the span in C151 and the range minimum in
C152. For standard PID control, the span and minimum of the AI and CON modules
are the same.
•
The 53MC5000 is set to accept a 1 - 5 V PV signal. If 0 - 5 V is required, enter
L417=1.
•
The 53MC5000 is set to accept a linear PV signal. If square root extraction is
required, enter L441=1.
6. Configure the Control Module parameters for Loop #1:
•
Enter the 10-character loop tagname in A00 and the 7-character Engineering Units
in A01.
•
Set the tuning parameters if desired:
C106 = Proportional Band
C107 = Reset time in minutes per repeat
C108 = Derivative time in minutes
•
The 53MC5000 is set for reverse action. If direct action is required, enter L106=0.
•
If setpoint limits are desired, enter the setpoint high limit in C125 and the low limit
in C126. Both limits are in Engineering Units.
•
If output limits are desired, enter the output high limit in C109 and the low limit in
C110. Both limits are in percent of output. Output limits are active in both Auto and
Manual mode.
