These conductors must be yellow throughout the entire circuit, including wiring in the control panel and the external field wiring. • White or natural gray represents a grounded circuit conductor. • White with blue stripe represents a grounded DC current-carrying circuit conductor. International and European standards require you to use light blue for the neutral conductor. • White with yellow stripe represents grounded AC current-carrying control circuit conductors that remain energized when the disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, you must use striping colors other than green, yellow or blue to uniquely identify the grounded conductors.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).

It only requires a small amount of compound. Gently place your valve into the engine. Use the Lapping stick by pushing the suction cup into the top of the valve and rotate it back and forth in between your hands. After about 10 seconds remove the valve and wipe the lapping compound off of both the valve and the valve seat. Inspect and make sure the contact area is uniform and about in the middle of the valve face. Repeat this process with the other valve and seat.

The downdraft carburetor allows it to be positioned above the engine and offers space saving advantages over the updraft and side draft designs. Twin cylinder engines frequently used down draft carburetors.

When checking these subsystems keep an eye out for evidence suggesting trouble such as sludge or debris in fuel, missing or damaged air cleaner, score marks on top of piston and cylinder walls, and excessive carbon build up on the intake and exhaust valves. All of these give you valuable insight to your problem.

A receptacle outlet is one in which one or more receptacles are installed for the purpose of attaching “plug and cord-connected” type devices, and a lighting outlet is one intended for a direct-wired connection to a lamp holder, luminaire (lighting fixture) or ceiling fan.

Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.
