MAINTENANCE   PROCEDURES  

 

The   load   bank   should   not   require   any   special   maintenance,   however   as   with   any  
electrical   equipment   periodic   checks   should   be   carried   out   to   ensure   the   equipment  
is   in   a   safe   and   satisfactory   condition.  
 
The   following   periodic   checks   are   recommended   on   the   load   bank;  

Check   the   inlet   and   outlet   grills   are   free   from   obstruction.  
Check   the   controls   and   connection   points   are   undamaged.  
Check   connection   cables   are   undamaged.  
Check   the   fan   rotates   freely   without   obstruction. 

 

 
FAULT   FINDING   PROCEDURES  

 

The   following   fault   finding   procedure   is   intended   to   identify   simple   operational   errors  
and   has   been   categorised   into   two   possible   problem   areas   as   follows;  
 

FAN   COOLING   NOT   OPERATIONAL  

Check   the   power   source   is   available.  
Check   the   phase   rotation   is   correct.  
Check   the   interconnecting   cable   connections.  
Check   the   fan   motor   operates.  
Check   for   air   blockage.  
Check   fan   blades   are   secured   to   the   motor   shaft.  

 

LOAD   BANK   DOES   NOT   PROVIDE   SUFFICIENT   LOAD   CURRENT  

Check   the   power   source   is   at   the   required   voltage.  
Do   not   exceed   the   maximum   rating   of   the   load   bank.   

 
Any   faults   not   corrected   by   carrying   out   the   above   procedures   may   require   the  
internal   wiring   or   components   of   the   load   bank   to   be   inspected   for   damage.  
 
Note:  Isolate   the   load   bank   from   all   sources   of   power   before   removing   any  

covers.   

 

Testing   the   load   bank   with   the   covers   removed   should   not   be   carried   out  
as   it   presents   a   risk   of   injury   or   death   by   electric   shock.  

 

Repair   or   replacement   should   be   carried   out   by   the   manufacturer.
