•
The temperature switch in the motor has switched off the
machine because
- the power cables have a total length of more than 20 m
(790”),
- the power cables have wire cross-sections which are too
small:
at mains voltage 220 V and 230 V are the wire cross-
sections smaller than 2.5 mm² (0.0039 sq.in.),
at mains voltage 400 V are the wire cross-sections smaller
than 1.5 mm² (0.0023 sq.in.),
- too much pressure was applied to the sanding plate while
sanding.
The motor must cool off and the causes for the problems
named above must be remedied.
•
An electrical component of the machine (e.g. capacitors,
contactor, cable, switch) is defective and must be inspected
by a qualified electrician and replaced if necessary.
•
Machine for mains voltage 400 V (three-phase AC):
The motor has the wrong direction of rotation. The phase
changing switch in the plug of the motor cable must be turned
by 180°.
Section 4.3.2, Switch-on procedure
9.2 THE MACHINE ATTEMPTS TO START UP BUT
IS NOT ABLE TO DO SO
•
At low temperatures: The machine is too cold and must be
heated up to room temperature in a warm room.
•
Cables which are too long or too thin are used for the
electrical connection:
- The power cables have a total length of more than 20 m
(790”).
- The power cables have wire cross-sections which are too
small:
at mains voltage 220 V and 230 V are the wire cross-
sections smaller than 2.5 mm² (0.0039 sq.in.),
at mains voltage 400 V are the wire cross-sections smaller
than 1.5 mm² (0.0023 sq.in.).
This causes of faults lead to a loss of power and are not
allowed for safety reasons!
•
The electrical network is not providing sufficient voltage
(undervoltage). Use a transformer if necessary (e.g. LÄGLER
®
part number 708.00.00.100 for 230 V).
