Dimensions and Mounting

Wiring

Attention: It is recommended to set up an uninterrupted power supply to avoid fluctuations on the device power line, as such fluctuations may cause device availability issues.

Configuration Procedure

prompt hierarchy. See Configuration Record Sheet for prompts.
You can also use the Increment or Decrement keys to scan the set up groups in both directions. Stop at the set up group tile that describes the group of parameters you want to configure. Then proceed to the next step.
3| Select a Function
parameter| Function key| Enter in the first function prompt of the selected set up group.
Increment or
Decrement keys| Press Increment or Decrement keys to display the other function prompts of the selected set up group. Stop at the function prompt that you want to change.
4| Change the Value or
Selection| Function key| Enter in the value or selection of the selected function prompt.
Increment or
Decrement keys| Increment or decrement the value or selection that appears for the selected function prompt
You can press the Increment and Decrement keys at the same time to move the current editable digit one step left.
| Enter the Value or
Selection| Function key| Enter value or selection made into memory.
6| Exit Configuration| Lower Display key| Exit the set up mode and returns to the main screen.

Start Up Procedure for Operation

It is required to enter the initial password and a new password when start up the controller for the first time. The initial password is 1234.
For more information of interface displays, see “Function of displays“ in UDC2800 Product Manual.

The controller is in manual mode.
2| Adjust the Output| Increment or
Decrement keys| Lower Display = OUT and the output value in Wo.
To adjust the output value and ensure that the final control element is functioning correctly.
3| Enter the Local Setpoint| Lower Display key| Until the required ‘SP’ and the Local Setpoint Value are displayed.
4| | Increment or
Decrement keys| To adjust the local setpoint to the value at which you want the process variable maintained.
Attention: The local setpoint 1 cannot be changed if the Setpoint Ramp function is running.
5| Select Automatic Mode| Man Auto key| Until ‘Auto’ is displayed under MODE. The controller is in Automatic mode.
The controller will automatically adjust the output to maintain the process variable at setpoint.
6| Tune the Controller| Setup key| Make sure the controller has been configured properly and all the values and selections have been recorded on the Configuration Record Sheet.
Refer to Tuning Set Up group to ensure that the selections for Proportional Band or Gain, Rate Min, and Reset Mins/Rpt, or Reset Rpts/Min have been entered.
Use Accutune to tune the controller. See ‘Accutune III’ in UDC2800 Product Manual.

Setpoints

You can configure the following setpoints for the UDC2800 controller.

• A Single Local Setpoint
• 2 Local Setpoints
• 3 Local Setpoints
• 4 Local Setpoints
• Up to 4 Local Setpoints and 1 Remote Setpoint

Changing the Setpoint value

Lower Display = SP or 2SP or 3SP, or 4SP (Value)
2| Adjust the Output| Increment or
Decrement keys| To change the Local Setpoint to the value at which you want the process maintained. The display -blinks” if you attempt to enter setpoint values beyond the high and
low limits.
The configured setpoint will be stored immediately.

Switching between Setpoints
You can switch Local and Remote setpoints or between two Local setpoints when configured.
Attention: The Remote Setpoint value cannot be changed at the keyboard.
To switch between Setpoints
Press the Function key to switch the four Local Setpoints and/or the Remote Setpoint.
Attention: “KEY ERROR” appears if:

• the remote setpoint or additional local setpoints are not configured as a setpoint source.
• you attempt to change the setpoint while a setpoint ramp/program is running.
• you attempt to change the setpoint with the setpoint select function key disabled.
• while a setpoint ramp/program is not terminated.

Viewing the operating parameters

Under the main screen, press the Lower Display key to scroll through the operating parameters listed in table below. The lower display will show only those parameters and  their values that apply to your specific model.

Control Algorithm is NOT configured as Three Position Step Control (TPSC), and Slidewire is connected.

RAMP XXXM: XXS| Setpoint Ramp Time—Time remaining in the Setpoint Ramp in minutes.
PXSX RA XXH:XXM:XXS PXSX RA XXX/M (0~999)

PXSX RA XXX/H (0~999)
