Operation

Setting Levels Diagram

This diagram shows all of the setting levels. To move to the advanced function setting level, you must enter passwords. Some parameters are not

displayed depending on the protect level setting and the conditions of use.

Control stops when you move from the operation level to the initial setting level.

Note: 1. Moves to operation level by software reset.

2. From the manual control level, key operations can be used to move to the operation level only.

Error Displays (Troubleshooting)

When an error occurs, the No.1 display shows the error code. Take necessary measure according to the error code, referring the table below.

Note: 1. If the input value exceeds the display limit (

−1999 to 9999), though it is within the control range,

will be displayed under

−1999 and

above 9999. Under these conditions, control output and alarm output will operate normally.

For details on the control range, refer to the E5CZ/E5CZ-U/E5AZ/E5EZ Digital Temperature Controllers User's Manual (Cat. No. H207).

2. These errors are displayed only when the PV/SP is displayed. Errors are not displayed in other display modes.
