Faults at the external fan

The following table shows the possible causes of and remedial measures for faults on forced-

ventilated machines.

Table 8-4

Cooling system faults

↓ High temperature rise with load

Possible causes of faults

Remedial measures

X Wrong direction of rotation of the external fan Check the electrical connections to the external fan.
X External fan is not running

Check the external fan and its connections.

X Reduced air flow

Check the air ducts; clean the machine.

8.9.6

Cooling system faults (water jacket cooling)

The following table shows the possible causes of and remedial measures for faults on water-

cooled machines.

Table 8-5

Cooling system faults

↓ Overheating

↓ Water leaking

Possible causes of faults

Remedial measures

Reduced cooling

Check the cooling water flow, increase the amount of cooling water if

necessary.

Cooling water flow rate too low

Consult the manufacturer. If the specified cooling water quality is

observed, the cooling system is maintenance-free.

Inlet temperature too high

Set the correct upstream temperature.

Cooling water supply switched off

Switch on the cooling water supply.

Cooling water contains frost or anti-

corrosion additives

Use cooling water of the agreed quality.

X Leaks in the cooling system

Consult the manufacturer.

X Defective cooling water connection

Find the leak and seal it.
