Operation

I Parameter Operation List

Switching to modes other than manual or protect mode is carried out using mode selection in the menu display.

The figure below shows all parameters in the order that they are displayed. Some parameters are not displayed depending on the protect mode

setting and conditions of use.

I Parameters and Menus

Note: For more details on the functions of each part and display contents, refer to the E5CK User’s Manual (H78).

Protect Mode

Limits use of the menu and A/M Keys. The protect function prevents unwanted modification of parameters and

switching between the auto and manual operation.

Manual Mode

The Controller can be switched to manual operation. The manipulated variable can be manipulated manually only

in this mode.

Level 0 Mode

Set the Controller to this mode during normal operation. In this mode, change the set point during operation, and

start or stop Controller operation. The process value, SP ramp, and manipulated variable can only be monitored

in this mode.

Level 1 Mode

The main mode for adjusting control. In this mode, execute AT (auto-tuning), and set alarm values, the control pe-

riod, and PID parameters.

Level 2 Mode

The auxiliary mode for adjusting control. In this mode, set the parameters for limiting the manipulated variable and

set point, switch between the remote and local modes, and set the loop break alarm (LBA), alarm hysteresis, and

the digital filter value of inputs.

Setup Mode

The mode for setting the basic specifications. In this mode, set parameters that must be checked or set before

operation such as the input type, scaling, output assignments and direct/reverse operation.

Expansion Mode

The mode for setting expanded functions. In this mode, set ST (self-tuning), SP setting limiter, select advanced

PID or ON/OFF control, specify the standby sequence resetting method, initialize parameters, and set the time for

automatic return to the monitoring display.

Option Mode

The mode for setting option functions. Select this mode only when the Option Unit is set in the Controller. In this

mode, set the communications conditions, transfer output and event input parameters to match the type of Option

Unit set in the Controller.

Calibration Mode

The mode for calibrating inputs and transfer output.

When calibrating input, the selected input type is calibrated. Whereas, transfer output can be calibrated only when

the Communications Unit (E53-CKF) is set in the Controller.
