Example of a local control panel (LCRP)

The scrubber local control panel contains:
1.             Touch screen. User Interface (UI) is integrated into the touch screen Human Machine Interface (HMI) panel. HMI Interacts with all components of the exhaust gas cleaning system, monitors and controls inputs and outputs via programmable logic controllers (PLC) 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.             Power light indicator. When this light is on, it indicates that it is the main source of power.
3.             Emergency power indicator light. When this light is on, it indicates that there is a 24 V emergency power supply.
4.             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. Remember, that START button can only be used in 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.
5.             Stopping the scrubber. Pressing this button activates the scrubber-controlled braking sequence. If this button is lit red, the scrubber has stopped (the start green button is off). If this button flashes red, the scrubber is stopped but it has not yet stopped completely (the start green button is lit). If the button is not lit, it means the scrubber is working.
6.             Main switch. After switching the switch to ON (1) position, electricity will be supplied to the exhaust gas cleaning system and its control panels. After switching the switch to OFF (0) position, the power supply will be disconnected. This switch can be locked with a padlock.
7.             The audible signal is switched off. When an alarm occurs, an audible signal sounds. When the button BUZZER OFF is pressed, the alarm tone is muted 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. It is free, unused indicator light.
8.             Reset. The causes of the alarm warnings must first be eliminated before resetting. Then press the RESET button to cancel all active alarms. Note that if the cause is not eliminated, the alarm warnings will reactivate. 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.             Cancel the emergency stop. Make sure it is safe to restart the scrubber. Then press the bottom - RESET EMERGENCY STOP RELAY, to cancel the emergency stop.
10.         USB ports.
11.         Emergency stop. Press this button to stop the scrubber in the event of an accident. Scrubber stops immediately (uncontrolled stop).
