Example of a remote control in the engine room central control room (ECRP)

The scrubber remote control is located in the central control room of the engine room:
1.             Touch screen. User Interface (UI) is integrated into the touch screen Human Machine Interface (HMI) panel. HMI Interacts with all exhaust purification system components, monitors and controls inputs and outputs via programmable logic controllers (PLCs) in the electrical cabinet. The operator can monitor the status and condition of various components on the touch screen, as well as control the system using HMI.
2.             The acoustic signal is switched off. An audible signal sounds when an alarm occurs. Pressing the BUZZER OFF button silences the alarm on all control panels. Note that pressing this button does not acknowledge or reset the alarm warning. If this button flashes white, one or more alarm alerts are active.
3.             The start of the scrubber. Press this button to start the scrubber. If at least one of the internal combustion engines is running, the scrubber start sequence will start, the scrubber intake valve will open and the bypass valve will close. If no internal combustion engine is running, the scrubber will switch to "standby" mode. Note that the START button can only be used on the active control panel. If this button is lit continuously in green, it means the scrubber has started or is running in the start sequence (the STOP button lights up red goes out immediately). If the start button does not light up green, the scrubber is not working.
4.             Application to start the engine A. Press the button START REQUEST ENGINE to prepare for starting engine A. When this button is pressed, the exhaust gas cleaning system is ready to accept the exhaust gas from engine A. When ready, engine A must be started within 5 minutes, or a new application must be submitted. For multiple engines, it is recommended to start them one at a time. Note that the scrubber must be in standby or standby mode when the engine is required to start. If not, first press the START button on the scrubber. The flashing yellow light button means: an engine start request is being executed. A steady yellow button indicates: the engine start request is completed the scrubber is ready. The engine can be started if the yellow light is on (5 minutes). The control panel may have several such buttons, one for each engine. The following description also applies to other installations generating exhaust gases (diesel engines for auxiliary generators, steam boilers).
5.             General fault alarm call. It sounds when an alarm warning occurs. The sound is muted by pressing the BUZZER OFF button.
6.             Cancel the emergency stop. Make sure it is safe to restart the scrubber. Then press the RESET EMERGENCY STOP RELAY button to cancel the emergency stop.
7.             Stopping the scrubber. Pressing this button activates the scrubber-controlled stop sequence. If this button is lit in red without flashing, it means the scrubber has stopped (the green button on the start is off). If this button flashes red, the scrubber is stopped but it has not not stopped yet (the start green button is lit). If the button is not lit, it means the scrubber is working.
8.             Reset. The causes of the alarm warnings must first be eliminated before resetting. Then pressing the RESET button will cancel all active alarm warnings. Note that if the cause is not eliminated, the alarm warnings will reactivate. Note that the RESET button can only be used on the active control panel. If this button flashes blue, one or more alarm alerts are active.
9.             Available unused button.
10.         Emergency stop. Press this button to stop the scrubber in the event of an accident. Scrubber stops immediately (uncontrolled stop).
