2.8INITIAL POWER UP SEQUENCE

The test sequence below occurs at power up.

2.The unit displays “-201-” or “-208-”.

3.The instrument begins normal operation. Units currently selected flash. Model CYD208s also indicate the current channel selected.

2.9POWER UP ERRORS

On power up, the CYD201/CYD208 checks internal memory. If a problem exists, an error message displays on the front panel of the instrument.

“Er01” indicates a hardware problem in the instrument memory. This error is not user-correctable. First perform the procedure in Paragraph 5.3. If unsuccessful, then call the factory.

“Er02” indicates a soft error in the instrument memory. To correct this error, close dip switch 1 on the rear panel for at least 5 seconds, then open it. Follow the calibration procedure described in Paragraph 5.3 after an error 2 reset.

“OL” indicates a voltage input overload. This can be caused by an open sensor or diode sensor wired backwards.
