2 Initial operation of the blast cleaning machine
ˆ Check that the shot valve is closed (abrasive shot valve handle
downwards, see fig. 5.1).
ˆ Check that the emergency shutdown switch is not actuated.
ˆ Switch the main switch of the machine to "ON". The control
lamp “Power“ on the control box lights up.
ˆ
Press the push button "Drive ON".
ˆ Press the push button "Fan ON".
ˆ Press the push button “Main blast ON”. The blast wheel motor
is started.
ˆ Observe the ammeter in order to check the power consumption
of the blast wheel motor. The motor requires a lot of power
(starting current) when it is started until it reaches its maximum
speed.
ˆ Once the blast wheel has reached its rated speed the current
drops to approx. 10 A no-load consumption.
ˆ If the ammeter indicates more than the normal current value after
10 seconds, interrupt the power supply and find the cause.
ˆ If the ammeter indicates a high load consumption after having
reached the idle-running speed, the shot valve may be partially
open or there may be another disturbance.
ˆ Find out the cause of the disturbance and, if necessary, contact
your
Blastrac BV customer service engineer.
