Re: Solenoids not activating when energized
Ok, so here is layout...

Pneumatically:
Compressor -> Accumulator -> Pressure Switch -> Regulator -> Solenoid -> Cylinder

Electrically
(12v) Battery -> light switch -> compressor
(24v) Batter -> Three position light switch -> dual solenoid (KOP)

So, in answer (in a long round about way) to your question...when we say manually (I just went through a 20 minute explanation with my pneumatics guy) we mean that we are changing the position of the blue test valve with a screwdriver. When we do this the piston extends and retracts. When we use the three position light switch to alternate power between the two sides of the solenoid we get no response from the cylinder and the orange light changes to reflect the side recieving power and remains solid.

(Whew...I'm the designated Chief Delphi person so please forgive me for my shortcomings...)
