Enable or Inhibit Close Order

Presentation

The application is used to inhibit the close order of the device in local or remote control mode.

The application takes into account an inhibit close order issued from:

The local selector switch wired on a digital input.
The remote controller using the communication network.

WARNING
RESTRICTED CLOSING INHIBITION Do not use the inhibit close order to lock the device in open position. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The inhibit close order inhibits only the close orders issued from the IO module, the FDM121 display, and a remote controller. The close orders issued from the front-face-button and BPFE or from the push-button directly connected to XF voltage release are not inhibited.

The close order can be inhibited either by a local command from the IO module or by a remote command from the remote controller.

When the close order has been inhibited locally, it can only be enabled by the local command from the IO module.

When the close order has been inhibited remotely, it can only be enabled by the remote command from the remote controller.

When the close order has been inhibited locally and remotely, it can only be enabled by the local command from the IO module and by the remote command from the remote controller.
