F ILTER C LEANING C ONTROLS
The Clean Air AutoPulse Controller has been implemented on all Clean Air Industries WeldStations as a filter cleaning controller. The controller is connected to a differential pressure sensor which
measures the pressure drop across the filters. This pressure drop is displayed in the lower right of the
front display on the controller. The controller can be manipulated using the buttons below the front
display.
The Pulse time on the valves is set internally and cannot be changed. The valves will open and
pulse for 0.2 seconds. There is a 20 second delay between the valve pulses. The valves will pulse in
sequence, alternating between the two valves until the all the pulsing cycles are finished. The
controller is set to pulse a full cycle so that all filters wear and unclog evenly. During pulsing, the
number of the valve which is being pulsed will flash on the lower line of the display for 0.2 seconds
while the valve is being pulsed.
Motor status is indicated below the Mode Display. This displays the contact status for activating and
holding in the motor contactor. When the controller is running, an indicator icon will be displayed. This
indicator resembles a pair of small rotating triangles. Additionally, input and output contacts can be
checked by holding down the ‘ESC’ key. The displ ay will change to show the appropriate input and
output contacts. Once power to the system is turned on, the controller will start up in Automatic
Mode. Several Manual and Option modes are available as well which are shown below.
The controller will always restart into automatic mode when power is cycled regardless of the
mode before the power was shut off.
To change modes, hold the ‘B’ button while pressing the ‘+’ or ‘ - ’ Button.
