■ Close in Alarm/Open in Alarm

When the Controller is set to “close in alarm,” the status of the alarm

output function is output as it is. When set to “open in alarm,” the sta-

tus of the alarm output function is output inverted.

Alarm type and close in alarm (normally open)/open in alarm (nor-

mally close) can be set independently from each alarm.

Close in alarm/Open in alarm is set in the “alarm 1 to 3 open in

alarm” parameters (setup mode). Factory setting is “close in alarm”

[ n-o ].

■ Parameter Operation List

Switching to modes other than manual or protect mode is carried out using the 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.

■ Parameters and Menus

switching between the auto and manual operation.
