Safety interlocks
Rotation - Recommendations
:
Triggering paint or solvents at speeds < 15,000 rpm may result in fluids entering the turbine bearing and
control circuit. Do not spray if the bellcup is not turning at a speed under 15,000 rpm. Therefore the trig-
ger valve, the injector flush valve and the outside bellcup wash valve must be closed when the bellcup
is not spinning
CAUTION : When the turbine is first started, the bellcup rotation speed must be rotating at least
15,000 rpm before opening the paint trigger valve.
Shaping air - Recommendations
:
Do not spray if the shaping air is not at least 80 NI/mn (3 CFM). Inadequate shaping air flow can cause
material to flow back and contaminate the outside and inside of the shaping air shroud and cover, caus-
ing application defects.
High voltage - Recommendations
:
To avoid air ionization and possible accumulation of electrostatic charges in the spray booth, turn off
the E.STAT when the trigger is turned off for any extended period of time (conveyor stops, absence of
parts, etc.).
Maximum speed
Excessive speed can cause serious damage to the turbine. Do not run at more than 45,000 rpm
maximum (loaded) and / or loaded.
CAUTION : The warranty does not cover damage caused by a rotation speed in excess of
45,000 rpm.
Vibrations:
If the
PPH 607
vibrates abnormally, this generally means the rotating parts are unbalanced.
There may be dry paint deposits on the bellcup, or it might be physically damaged or dry paint might be
trapped between the injector and the clip. There also may be paint on the groove receiving the clip or on
the clip itself causing unbalance. If this happens, the problem
must be
corrected. Significant unbalance
will damage the bearing surface and cause the turbine to fail.
CAUTION : The warranty does not cover damage caused by running an unbalanced turbine.
