PROBLEM
PROBABLE CAUSE
SOLUTION
Unit will not
operate
Mains connector not fitted
to control panel
Connect to rear of control panel
(see p
age 12 -

Press circuit breakers inwards
(see page 11 - Fig 4, CU1003).
If they trip out again after turning
on the unit call for an engineer.
Poor dust cloud
adhesion to
product
Voltage output too low
Adjust the generator head
position within the dust cloud.
Conduct SET test (see page 17)
Earthing not correct
Reset the earth wiring and
contacts
Dust type not suitable for
electrostatic application
Contact product supplier.
Dust particles too fine.
Dust particles too large
Contact product supplier.
Dust in the air
(dusting)
Electrostatics are not
turned on
Turn on at the control.
Conduct SET test (see page 17)
The low voltage cable not
connected or is damaged
Replace cable if needed.
(This cable must be supplied by
SAS).
Earthing not correct
Reset the earth wiring and
contacts.
Powder very fine
(under 15 microns)
Powder supplier to reformulate
the powder.
Applicator Air pressure too
high
Turn down the pressure at the
applicator.
Operators are
getting static
electric shocks
Earthing not connected
Reset the earth wiring and
contacts.
Operator not wearing
conductive clothing
Purchase conductive foot gear,
or conductive operator earthing
straps.
Static Electric
shocks from the
intake and exit
vibratory
conveyors:
No earthing on the
vibratory trays
Fit earthing straps to both
conveyors.
