4. Operation
4.1 How to Power Up the Controller
When the power is applied, the controller will run three diagnostic tests. All the
displays will light and then the controller will go into automatic mode after 20
seconds.
If one or more of these tests fail, the controller will go to the Fail-safe Manual Mode,
and “FAILSAFE” will flash in the lower display.
If the output type is Position Proportional, and AUTO-CAL has never been done, a
prompt “CAL MTR” will appear suggesting that the controller be calibrated.
(See Appendix D – Position Proportional Calibration.)
Key Error
When a key is pressed and the prompt “KEY ERROR” appears in the lower display,
it will be for one of the following reasons:
• parameter is not available,
• not in Set Up mode, press SET UP key first,
• key malfunction, do keyboard test.
4.2 Monitoring Your Controller
Operator Interface
The indicators and displays on the operator interface let you see what is happening
to your process and how the controller is responding. Figure 1-1 is a view of the
operator interface. A description of the displays and indicators is included.
Decimal Point Position
None, one or two decimal places are indicated on configuration. When a single
decimal position has been configured and values greater than 1000 are displayed,
the right-most character is blank, but the decimal point will be lit.
Viewing the Operating Parameters
Press the LOWER DISPLAY key to scroll through the operating parameters listed in
Table 4-1. The lower display will show only those parameters and their values that
apply to your specific model and the way in which it was configured.
