Mechanical & electronic emergency stops in containerised diesel generator sets

Normally, a cool-down process is required for a shutdown of the diesel generator sets. In case of an emergency – such as fire, gas leak etc – the emergency stops are useful to bypass time delay to cut off the supply of fuel directly. So that an absence of fuel prevents the diesel generator from operating. There are mainly 2 types of emergency stops: Electronic & Mechanical.

• Electronic: when pressing the electronic emergency stop button, the control panel will send signals to halt the fuel pump operation safely.
• Mechanical: when pulling the handle of the mechanical emergency stop to full extend, a conduit attached (with a wire within) will close the opening mounted on the fuel pump.

Our containerised diesel generator sets are equipped with electronic emergency stops. For local projects in Hong Kong, an extra mechanical emergency stop is often installed to provide additional protection to meet fire safety requirements. If you need to perform an emergency shutdown operation, attempt the electronic emergency stop before using a mechanical emergency stop. After using the emergency stops, the stop devices have to be restored before restarting the generator set.

Different users have their preferences on power distribution in a generator set, and this area can be customised. As requested, this time we added a cable outlet cover for extra protection and opening vertically. The gas spring within holds the cover firmly once opened. This protects users’ fingers from hurting while connecting the cables. Additionally, after opening up the cover, it is slightly downward instead of completely horizontal. This provides a water repellent function along with the rain guard at the top.

The Function of a Circuit Breaker
A circuit breaker is an electrical switch that operates automatically to control or protect a generating unit. It controls circuits depending on operational needs and connects multiple generators for parallel applications. For protective use, a circuit breaker helps to detect and interrupt fault currents. It prevents an electrical circuit from being damaged caused by overload or a short circuit.

The Protection of a Circuit Breaker
To protect users against direct contact of exposed live parts of a circuit breaker, a barrier is firmly secured to separate the electrical cables. The barrier is made of wood with high stability and durability, and a tool must be needed to remove the barrier.
Additionally, if a generator set is placed in the countryside, there are chances that bugs and snakes may go inside the panel doors and damage the cables. In our containerised diesel generator sets, the barrier of the circuit breaker also helps prevent these small animals from entering the area inside the panel.

Genuine parts are important for Cummins diesel generator maintenance. When looking for replacement parts, we need to have an Engine Serial Number (ESN) in order to ensure the part item is suitable. Part numbers can also be helpful for you to look it up. Yet, you have to ensure this is an active part number, since the part number may become inactive after a period of time. For overhauling, a Critical Parts List (CPL) is useful for you to get all the essential parts for the diesel engine maintenance. For instance, the engine CPL of a KTA50-G3 is 2227. The Critical Parts List Data For CPL2227 includes parts such as camshaft, turbocharger, thermostat, injectors etc.
