The main purpose of sm electrics‘ Emergency Engine Order Telegraph system is to operate as the last back-up manoeuvre command transmission system, in case the classical propulsion remote control system and its backup mechanism fail.
In such emergency case, the emergency engine order telegraph system is in use to transfer manoeuvre commands to the engine control room or, if required, directly to the engine room‘s ME local station. The by push buttons given manoeuvre command activates a visual and audible alarm as long as the command has been accepted by corresponding operation at the selected participants.
The centralized A067 mt-Bus controller, mostly located inside the engine control room console, controls and monitors all network participants and provides further interface signals for ER call, VDR and connected IAMC systems.
