Set the high and low-pressure drop settings using the right and left hand knobs, respectively, on the face
of the gauge. The timer will initiate pulsing of the valve solenoids when the collector pressure drop rises
to the “high” set point and continue until the collector pressure drop is lowered to the “low” set point.
Zero the photohelic gauge using the adjustment screw on the face of the gauge.
Separate box penetrations are recommended for the line power and output lines.
Note: Metal shavings
from the penetrations should be cleaned from the face of the timer board.
Establish power to the board and adjust the “ON” time, “OFF” time, number of outputs used and number
of blowdown cycles required. See programming instructions for details.
