TROUBLESHOOTING
Problem: Low output intensity
Other symptoms: Fails to cure adhesive in allotted time
Possible Cause Testing Corrective Action
Lamp Beyond Useful Life Use a radiometer (model
Dymax Accu-Cal 20) to
measure actual output
intensity. Consult manual
for proper output. Replace lamp if beyond useful life
(typical = 1000 hours)
Transmission Loss in Light
Guide Too Great Compare light guide output
against new light guide (or
use the Dymax Light guide
Simulator - P/N 36987) to
determine transmission
loss. Replace light guide
Transmission Loss in Filter
(Blue Filter at End of Light
Guide) Too Great Compare filter output
against new filter to
determine transmission
loss. Replace filter
Contaminants on Light
Guide or Light Guide Filter Visually examine ends of
light guide and filter for
contaminants. Clean with isopropyl alcohol (or
equivalent) or replace light
guide/filter if it can not be
cleaned.
Lamp Not Installed
Properly Visually check to make
sure the lamp is seated
flush in the lamp mount
assembly (any error in
installation could cause a
low output). Properly install lamp assembly.
See Figure 1.1
Problem: Unit will not dispense adhesive
Possible Cause Testing Corrective Action
Air Line Not Connected Check connections and
source of incoming air. Connect a 40-60 psi air source
Pressure Regulator Set on
Zero (0) Check pressure gauge for
reading. Turn the pressure regulator
clockwise (CW) to increase
output pressure
Plugged Air Line or Needle Visually inspect all air-lines
(internal tubing and
external output tubing) for
blockage. Replace blocked tube
Dispenser Solenoid
Malfunctioned Measure the voltage being
delivered to the solenoid Replace solenoid, if defective
