fault
In the 1 Torch module K201 should energize when W5 does. Either it
failed to energize or the pressure switch PS2 is failed closed.
704 Contact Start pressure fault
Pressure switch PS2 detects less than 35 PSI. Normal pressure is 75-85
PSI. No air connected to the 1 Torch module inlet or it's too low pres-
sure; if using optional single stage filter the element may need cleaning
or replacement, refer to maintance section. ;1 Torch pressure regulator
set too low; 1 torch module solenoid SOL4 has failed; Relay PCB does
not apply 24 VAC to SOL4.
