REX615 Operation Manual
Close delay mode and Close delay need to be set to be able to control objects with the closing delay.
The closing operation from the LHMI can be delayed by a predefined period of time.

    • If there are several controllable objects, select the object and press to confirm the selection.
  2. To confirm the operation, select Yes and press .
    • After the control operation is confirmed, the delay is activated.
    • Cancel the control by pressing any key when the delay is active.

    Note: When the delay is activated, it is recommended not to change any closing delay parameters in the WHMI during the delayed time as it affects the delayed circuit breaker closing. If the delayed circuit breaker closing fails, the LHMI status shows Select timeout or Status only.
Note: The display backlight stays on for the delay also if the backlight timeout is shorter than the closing delay.
