    • Temperature Rise
    • Oil Leakage
    • Rise in Water Temperature
    • Less Water Flow
    • Less Air Flow
    • Noise and Vibration
    • Water Carry over
    • Consult Us for Other Problems
 
TROUBLE =     CAUSE =      REMEDY =

Lowering of Cooling capacity
: 1. Motor stoppage
: 1. Electric blackout
2. Fuse burnout due to damaged Contacts
3. Insufficient switch capacity
4. Bad switch contact
: 1. Contact power company
2. Get proper fuse
3. Change to proper switch
4. Adjust / Clean Contacts.
    Top^
: 2. Sudden lowering of motor speed(rotations per minute)
: 1. Defective starter
2. Too heavy load
3. Low supply voltage
: 1. Check starter for defects
2. Reduce the load by checking motor current
3. Consult power company
     
: 3. Cannot rev up motor speed (rotations per minute)
: 1. Defective starter / starter connections
2. Connection of rotary and fixed section
3. Motor winding damaged
: 1.  a. Correct connection according to name plate
     b. Check supply voltage across all 3 phases
     c. Check current in all 3 phases
2. Send out to repair shop
3. Send out to repair shop
     
: 4. Fan Stoppage
: 1. Jammed Bearing
: 1. Replace bearing
     
    Top^
Oil Leaking , others
: 1. In case of gear speed reducer oil leakage (DMA 1616, DMB 1616 models)
: 1. Too much oil
2. Loose bolt
: 1. Lower the oil face to proper level
2. Tighten properly

     
    Top^
Noise and Vibration
: 1. Fan mounting loose
2. Fan blocks loose
3. Fan unbalanced
4. Motor bearing faulty
5. Hub mounting on motor shaft loose
6. Many parts rubbing against tower components
: 1. Tighten mounting bolt and correct/ replace if needed.
2. Tighten blade in hub
3. Rebalance and adjust
4. Check and grease or replace bearing on motor.
5. Tighten and use end plate and shims if required.
6. Give proper clearances and adjust/ align components
     
     
Temperature rise
: 1. Motor getting over heated
: 1. Too heavy load
2.  a. Lowering of voltage supply
     b. Unbalanced voltage supply
3. High surrounding temp
4. Contact between rotary and fixed section
: 1. Lighten load proper level
2.  a. Consult power company
     b. Consult power company
3. Consult "Advance"
4. Change bearing or supplement grease
     
     
Rise in water temperature
: 1. Water flow above specified flow
2. Air flow below specified flow
3. Load higher than design
4. Fill checked or coated
5. Fresh air intake not sufficient or area sufficient or area around tower not as     specified.
6. WBT high
7. Water bypassing fills
8. Sprinkler jammed/water not being sprinkled and distributed
: 1. Regulate to correct flow rate.
2. Adjust blade angle check and clean jail.
3. Adjust load to correct level.
4. Clean / replace fills. Use proper water (Make up )quality
5. Improve ventilation and ensure exhaust air does not get recycled.
6. Check design condition and ensure no recycling of exhaust air.
7. Check sprinkler head and pipe leakages.
8. Repair sprinkler and distribution system.
     
Water flow Less
: 1. Filter chocked
2. Sprinkler pipes chocked
3. Level of water low in pump
4. Pump small
: 1. Clean water filter.
2. Clean pipes and holes
3. Adjust float/ inlet flow ensure proper make-up
4. Replace for correct flow volume
     
    Top^
Air flow low
: 1. Fan speed low
2. Fan blade angle incorrect
3. Inlet jali chocked
: 1. Check bearings/motor
2. Correct blade angle to required setting
3. Clean air path
     
     
    Top^
Water carry over
: 1. Sprinkler rotation too faster
2. Blocking of filter
3. Defective eliminator
4. Sprinkler too high above filter
: 1. Adjust sprinkler angle as to match the specified rotation
2. Clean up any blocked part
3. Replace eliminator
4. Adjust as specified:
    25mm - DMA 2116 to DMB 4116
    50mm - DMA 6616 to DMB 8416
    75mm - DMA 1260 and above
