Adhesive flow-
ing out of
one/some
valves when
not triggered
Failed valve in the
open position.
Replace valve.
Adhesive pressure too
high.
Reduce air pressure to air motor.
Gun will not
heat.
Heat rod failure in man-
ifold.
Check resistance on heater rods. Repair manifold if heater rods mea-
sure open.
Loose cable connec-
tion at system or mani-
fold.
Check cable connections on both ends of the hose.
RTD failure. Check resistance on the RTD, if out of normal range replace RTD.
Incorrect RTD setting in
the ADM setup.
Set correct RTD value in the AMD setup screen. Consult manufacture
for correct RTD value.
Thermal cutoff is
tripped.
Measure resistance of the thermal cutoff. If open, replace.
Adhesive leak-
ing from mani-
fold or valve.
Valve is loose on the
manifold.
Tighten screws on loose valve.
Valve o-ring failed. Replace o-rings on the back of the leaking valve.
Failed valve, adhesive
leaking out middle of
valve.
Replace valve.
Hose loose. Tighten hose.
No melter
heat.
Fuse blown in F1 and
F2.
Check heater rods for a short or a short between the rod wires and
ground.
Cable to over-tempera-
ture switch off or bro-
ken.
Check connection of cable to over-temperature switch both to main
board and to switch. If connection good, look for break in wire.
Over-temperature
switch tripped.
Measure over-temperature switch resistance. It should read close to 0
ohms when at room temperature. If open, replace over-temperature
switch.
Air motor will
not function.
No air being supplied to
air motor.
Check incoming air supply. Check that air solenoid is adjusted for air
motor.
Air solenoid not adjust-
ing the air motor.
If air can not be adjusted at the air solenoid, check voltage, if 24VDC
present at air solenoid replace air solenoid.
Air present at air motor
but it will not work.
Replace air motor.
System not
turning on.
No power to unit. Check main power breaker is turned on.
Check that power plug is connected.
