Product: DCP 250
FAQ: DCP 250 Start Up Guide
Question
This guide, along with manual (57-77-25-18), can be used to configure the DCP250.
Answer
Use the below information to install, wire and configure the DCP 250.
1. Installation –Section 2.2, Page 2
2. Wiring –Section 4.5, Page 13 to 28
3. Keypad Navigation –Section 5.5, Page 30

Global Technical Assistance Center Page 2
4. Application Setup –Section 7, Page 33
Before beginning configuration, consider how the controller will be used in your
application. For instance, how many control loops are needed, is cascade or ratio control
required, will the unit control a valve motor, do you need setpoint profiling etc.
Consideration should also be given to the output types, alarms and tuning method.
Pre-commissioning Considerations
An easy Setup Wizard is available for basic applications (see page 42) where the most
commonly required parameters are present for adjustment in turn. The wizard has a sub-
set of the full configuration menu options. For more complex applications where the
wizard is not sufficient, consideration must be given to the following fundamental
questions:
If fitted, how will the 2nd input be used?
• One loop only (if the 2nd input not fitted or not used in this application)
• Two independent control loops (see page 49).
• Valve feedback for loop 1 (see page 87).
• A “redundant” backup for the 1st input (see page 85).
• Cascaded with the first control loop (see page 80).
• A reference input for ratio control (see page 83).
How will the instrument physically control the process?
• Primary only or primary & secondary control outputs (see page 212).
• Direct valve motor drive outputs (TPSC, Three Position Step Control) (see page 86).
Which outputs will be used for control, and are alarms or event outputs needed?
• Output configuration (see page 56).
• Alarms & Profile Events (see page Alarm Types 208 & 226).
What are the sources for the setpoints?
• Local setpoint(s) only, or a remote setpoint input (see page 217& 228).
• Profile Control (see page 89).
Is Input re-configuration required?
• Analog input calibration & scaling (see page 73).
• Digital input functions (see page 77).

Global Technical Assistance Center Page 3
Which other features are to be used?
• Data Recorder (see page 99).
• Serial Communications (see page 111).
• USB Interface (see page 98).
One Loop
Two Loop, Cascade and Ratio
CAUTION: Configuration & commissioning must be completed before proceeding to Operation
Mode. It is the responsibility of the installing engineer to ensure that the configuration is safe.

5. Main Menu Access
Holding down and pressing from Operation Mode and most other screens will
cause the unit to enter the Main Menu. Each time or is pressed, the instrument
moves to the next menu level above. Sub-menu levels will require this sequence to be
pressed more than once in order to reach the Main Menu.
The factory default unlock code is 10 for all modes
6. Setup Wizard –Section 8.3, Page 42
An easy Setup Wizard runs automatically at first ever power-up. Follow the Wizard to
setup parameters required for basic applications. The parameters covered by the Setup
Wizard are marked with a w in the following sections covering the configuration mode
sub-menus. Once completed, the Setup Wizard exits to Operation Mode. Experts or
users with more complex applications can select the parameters they wish to set-up
directly from the Configuration Menus bypassing the Wizard.
7. Configuration –Section 8.5, Page 45
Use Main Menu Access above to enter into Configuration Mode. The factory default unlock
code is 10. Holding down and pressing toggle you back to the previous screen.

8. Testing System –Operation Mode –Section 8, Page 36
Pressing the key cycles thru the Operation screens
a. Verify Input reads correctly
b. Check Output.
i. Go to the Auto/Manual Control screen and select Manual Control.
ii. Adjust % PWR using the Up and Down keys and observe final control.
iii. Return to the Auto/Manual Control screen and select Automatic Control.
c. Make sure Control Loop is set to Control Enabled.
d. Tune Loop –
i. Set Main Setpoint –In the Operation Mode, continually press the key until
the Setpoint Value screen appears. Adjust Main Setpoint using the Up and
Down keys.
ii. Automatic Tuning –Section 8.11, Page 70.
The automatic tune menu is used to engage pre-tune and/or self-tune to
assist setting up proportional bands and the integral and derivative time
values used by the control loops.
Pre-tune can be used to set PID parameters approximately. Self-tune (Pre-
tune needs to be run first) may then be used to optimize the tuning if
required. See the Tuning section on page 101 for more information.
FYI: Pre-tune can be set to run automatically after every power-up by
enabling Auto Pre-Tune (Not Recommended).
Steps to Automatic Tune
The Automatic Tuning Menu is entered from the Main Menu
Hold down and press to enter the Main Menu.
Press Up or Down to select the Automatic Tuning Menu.

Global Technical Assistance Center Page 6
Press to enter the Automatic Tuning Menu.
Enter 10 as the Unlock code.
Pre-Tune Method –Choose Pre-Tune at Value
Enter Pre-Tune Value. This is a Setpoint that in the range of the process.
Recommendation is at least 5% greater than the current Setpoint
Pre-Tune save Location. Here you can store the Pre-Tune values to one
of 5 different PID sets. Recommend PID Set 1.
Run Pre-Tune on Set 1 now? Select “Yes”to start the tuning process.
Once Yes is selected, a Status screen will appear with the Tuning status.
When “Stopped” appear on the lower half of the screen, Pre-Tune is
finished. Press enter to proceed.
Engage Self-Tune. If Yes is elected the Self-Tune feature will be active
and the Tune Led is lite continuously.
Auto-Pre-Tune at Power-Up? Recommend “None”.
DCP cycles back to step 6. Hold down and press to enter the Main
Menu.
Press Up or Down to select Operation Mode, then to exit.
Verify tuning by changing Setpoints. Make changes to PID values, if
necessary, in the Control Group.

9. Profiler Editing –Section 8.8, Page 66. Profiler explanation - Section 16, Page 89.
The Profiler allows for 64 Profiles and a maximum of 255 segments shared among Control
Loop 1 & 2.
a. Profile Mode Entry
Hold down and press to enter the Main Menu.
Press or to select the Profiler Setup Menu.
Enter 10 as the unlock code
Press to enter Profile Setup Mode.
b. Navigating the Profiler Setup Menu
Press to move forward, or to move backward through the screens.
Press or to select or change a value.
Holding down or for more than 1 second skips immediately to the
next/previous screen accepting all values as shown.
Hold down the and press to return to the Main Menu.
