INHIBIT Push-button When the INHIBIT push-button is operated, the selected control card is placed in the inhibit mode. This prevents the operation of any configured relay output alarm functions. Inhibit can only be used if the Engineering Key is fitted to the Engineering Card, however, if the Engineering Key is subsequently removed the selected control card remains in the inhibit mode. 3.3.15 Engineering Serial Port The Engineering Serial Port is a miniature DIN socket which provides three functions: a. Connection point for the Engineering Key to unlock the engineers functions. b. Connection point for the External Engineering Interface which allows each control card to be configured by an external PC running the configuration software. c. Connection point for a serial printer which can be used to provide a hard copy of the control card configuration data and status.
