Boolean logic or relay logic can be used in a simple sequential control.<\/span> For example, let’s say we want to turn (turn on) a pilot light if either a fan or a fan of B work.<\/span> To detect the status of the fan mounted differential pressure switch on the fan.<\/span> The switch contacts will open if the pressure is low and the fan will shut down if the high-pressure fan.<\/span> To make the pilot light turns on when the fan is on, then the fan is mounted parallel contact as shown in Figure 2.15.<\/span><\/p>\n

If we want to turn the pilot light when the fan A fan B and active, then both the switch contact must be installed in series.<\/span>

With the notation of Boolean logic, if the pilot light interruption event labeled C, then the next two sequential events can be written sebgai follows:<\/span>
\n If (A or B) then C (a parallel circuit – row 1)<\/span>
\n If (A and B) then C (series circuit – line 2)<\/span><\/p>\n

Say, we want the pilot light is lit when one of the fan is working, but when the second fan will not turn on the lights work.<\/span> For this purpose single-pole switches needed double-through (SPDT) as shown in Figure 2.16.Terlihat in the picture, how to contact the double-through can be used to turn on lights when a fan works.<\/span> But when the fan works even light goes out.<\/span> This logic can be expressed as follows:<\/span>
\n If (A or B) and NOT (A and B) then C<\/span><\/p>\n

SPDT contacts are widely applied in the two-position thermostat, and differential pressure switch.<\/span>
