Lock out all electrical power to the unit and
bleed the compressed air supply. Check for
debris, valve wear, pneumatic tubing fault, or
diaphragm failure by removing the diaphragm
cover on the pulse valves. Check for solenoid
leaks or damage. If pulse valves or solenoid
valves and tubing are damaged, replace.
Solid-State Timer failure
Using a voltmeter, check supply voltage to the
timer board. Check and replace the fuse on the
timer board if necessary. If the fuse is good and
input power is present, but output voltage to the
solenoid valves is not, replace the timer board.
