Control Test and Calibration
General
Conduct the following checks on the 2301E-ST. Then verify the functioning of set points and adjustments.
1. Connect a computer to the communication port. Start the Control Assistant software in accordance
with the instructions in Chapter 3. Verify correct voltage and polarity on the power supply input of the
control.
2. Verify the controller ID on the 2301E-ST in menu U**APPLICATION INFO**. The Application ID
message “5418-6351” with the revision level (new, A, etc) should appear.
3. Select the Configure and Service Menu. Verify that all set points are as recorded during installation.
Repeat for the other menus. If any differences are found, change the set point(s) to the correct
value. Click the “SAVE VALUES” icon on the tool bar. Remove power from the control for at least 10
seconds. Verify correct values were retained during power down. Failure indicates the control has
failed and should be replaced.
Discrete Inputs
Run the following test to verify the function of the discrete inputs. DO NOT PERFORM THIS TEST WITH
THE TURBINE RUNNING!
Repeat this step for all discrete inputs. Close the appropriate input. The status in the Service Menu R**
DISPLAY D_I/O STATUS** should switch from OPEN to CLOSED. If the value does not change when the
contact is closed, the control has failed and should be replaced.
Discrete Outputs
Verify operation of the Discrete Outputs, by referring to the Service Menu S**HARDWARE OUTPUT
TEST** sheet.
With the turbine shut down, enable the manual relay driver test. Open another inspector sheet, select
Service R**DISPLAY D_I/O STATUS** and monitor the discrete outputs. From the relay test procedure,
each discrete output may be activated and its operation verified. If the output is activated, the voltage
measured between terminal 42 and the appropriate output terminal (44–47) should equal input voltage at
terminal 42 and 41. Testing can be monitored visually by observation of the green LED near terminal 9
and 10, or by listening for an audible ‘click’. The manual relay test must be disabled (status “FALSE”) or
the control will hold the actuator current to minimum.
