5.5 Troubleshooting, continued
C. The Light briefly turns on and then off; Fan operates
1. The Lamp may have a faulty filament. Turn the Intensity Control Knob to
maximum setting to the test lamp.
2. If the Lamp fails, replace the Lamp (See 5.2 Lamp Replacement).
3. Examine the Lamp Socket assembly for damage and continuity.
D. The Light will not turn on, Fan operates
1. Replace the Lamp (See 5.2 Lamp Replacement).
E. The Light is dim or non-existent; Fan does not operate
1. Make sure to use the correct model for the power available. Running a 240v
unit in 120/100v conditions will stop the fan and dim the lamp.
F. The Light is on; Fan does not operate
1. Return to Galiso, Inc. by calling (800) 854-3789 to receive a return
authorization number and shipping instructions.
G. The Light is off; Fan does not operate
1. Make sure the power cord is inserted completely into the IEC connector and
also into the correct power source.
2. Check the power cord for damage.
3. Check the fuse.
H. The Light Guide is burning
1. Check the fiber type. If a Light Guide is in use that is not a Galiso, Inc. fiber
optic Light Guide, it may be plastic and susceptible to burning. Using a glass
fiber Galiso, Inc. Light Guide is recommended.
2. Some epoxy types cannot withstand the high temperatures developed in the
light source. Call the supplier if there is any question as to the epoxy used to
manufacture the fiber optic input.
3. Check the Lamp type. Replace the Lamp with Galiso, Inc. approved part
number: 85-11-0028, EKE 150W, (See Table 5-1, Spare and Accessory
Parts). Light Guides damaged by use of non-approved Lamps will void the
fiber warranty.
