Checking the direction of rotation
at initial pump start-up
Remove the blank-off flange on the inlet and exhaust port.
Fit a pressure gauge at the pump inlet.
Set the main switch to position
1
.
To start or stop the Roots while the ADP is running, set the
CMD.ROOTS menu on ENABLED (see
C 30
).
Press on the
ROOTS
key until the word ROOTS disappears from the
display.
Start-up the pump by pressing
START
and stop it after few seconds:
– if the pressure indicated is less than 5.10
-1
mbar, the direction of
rotation is correct.
– if the pressure increases,
invert two phases at the main power input
female connector
, or from main switch terminal (or refer to
B 50
for
hardwired connections).
Check the direction
of rotation at initial
pump start-up
At the initial start-up, provide protection against the risk of crushing related
to the rotating parts in the inlet.
A non-powered Roots can be driven by another pump in rotation (risk of
crushing). Always connect the pump inlet port before starting the pump.
When the main electrical switch on the top of the pump is set to “0“,
the part supply between the power plug and the main switch remains
energized.
Risk of electrical shock in case of contact.
Disconnect main electrical cable before servicing.
Hazardous voltage enclosed.
Voltage or current hazard sufficient to cause shock.
Disconnect and lockout power before servicing.
Any intervention must be done by trained personnel only.
