5.2.1 Compressor
The compressor operates directly from the 230VAC power and is supplied directly via a
breaker to the compressor motor starter box. From there, the pressure switch turns on
the compressor as needed based on tank pressure. The air is dispensed through the air
hose which is restricted by an air solenoid valve, allowing air to reach the blow gun
when the appropriate function button is activated. The programming for the timer and
button light indications is controlled by the control module.
5.2.2 Vacuum
The power to the vacuum motor operates on 230V AC power that comes from the main
electrical box via a breaker within the box. The vacuum is actuated based on an output
signal from the control module which is based on an input from the appropriate lighted
button. There is also a float switch inside the top of the vacuum tank that stops its
function if the tank is completely full.
5.2.3 Lights
The lights operate on 12VDC power from the main electrical box. The signal from the
button is also a 24VDC signal that is communicated to the main electrical box and then
translated to the needed 12VDC coming out.
5.3 Wayside (Solar and 120V)
The Wayside units are both powered by a 24VDC battery pack that powers the system
directly. The difference in the Wayside Solar and 120V units is how the battery pack is
charged. The functionality of the two types of Wayside units is very similar apart from
the battery charging.
5.3.1 Battery Pack
The battery pack is common to both Wayside (Solar and 120V) units and is made up of 2
– 12V batteries connected in series to produce 24VDC that powers the Wayside units.
The pack powers the unit fully and is discharged most heavily by the compressor
drawing approximately 20A and the vacuum motor drawing approximately 10A. The
pack will have a steady draw even when tools are not activated due to the lights on the
button, the control module being active, and the cellular gateway being active. The
main disconnect switch will turn off all power draw from the battery pack. The charging
that occurs on the pack is varying depending on the type of charger (solar system or
120V charger). The pack is a nominal voltage of 24V (when tested as a pack - across the
