Audio Visual Alarm Panel for Engine Safety

Audio Visual Alarm Panels for engine safety is a proven product of Power Control Engineers. These panels are used for applications - Main Propulsion Engines, Diesel Generating Sets & Fire Fighting Pumps.

These panels are designed, developed, manufactured and installed by Power Control Engineers. Number of alarms and trips are as per application & customer specific.
Repeat alarm logic is used for all faults. That is, if one fault is active and the other fault occurs, alarm will be sounded for the other fault with the indication.

  • Type I : Conventional Panel with contactor logic
    This panel has the conventional logic of contactors and relays. Alarms and trips are generated from the safety switches mounted on the engine. Indicating Lamps / Annunciation windows are used for the indications of various faults. All the alarms and trips have a separate indication.

  • Type II : Microcontroller based Panel
    This panel uses Microcontroller based control cards developed inhouse by Power Control Engineers. The sensors used are of Analog type such as 4 to 20 mA transmitters. These transmitters are directly connected to the control card of the Panel. Instrumentation of various parameters is generated from the same transmitters. Analog gauges are used to display the various parameters.

    Different transmitters and switches are used to generate alarm and trip faults. Indicating Lamps / Annunciation windows are used for the indications of various faults. All the alarms and trips have a separate indication.

  • Type III : PLC base Panel
    Control system is based on modular PLC with an Operator panel (HMI), approved by most of the Classification Societies. Software for PLC and HMI is developed by Power Control Engineers. The sensors used are of Analog type such as 4 to 20 mA transmitters. These transmitters are directly connected to the PLC in the Panel. Instrumentation of various parameters is generated from the same transmitters. All the parameters and the faults are displayed on the HMI. Events can be logged in the panel as a standard feature.

    Different transmitters and switches are used to generate alarm and trip faults.
    Advanced data logging and trending of parameters is easily possible with this type of control system.
