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 ;
1)
Check the inlet and outlet grills are free from obstruction.
2)
Check the controls and terminal shrouds are undamaged.
3)
Check the fan rotate freely without obstruction.
4)
Check internal wiring for lose connections or damage.
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 and switched ON.
Check the mains cable connections.
Check the mains fuse in the front panel mains socket
Always replace fuses with the correct rating ( see specification )
Check the fan motor operates.
Check for air blockage.
Check fan blades are secure to motor shaft.
LOAD BANK DOES NOT PROVIDE SUFFICIENT LOAD CURRENT
Check the power source is at the required voltage.
Check the load cables are secure.
Check the load cable is inserted correctly.
Check the required current channels have been selected.
Compare the current values with the specification table.
Identify individual current channels for reduced output.
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 power sources before removing any covers.
Testing the load bank with the covers removed is not recommended as
high voltages can be present on internal components and the air flow is
reduced.
Repair or replacement should be carried out by the manufacturer.
