Procedure
3. Improper rotator type DIP
switch setting on Atomizer
Card
4. Failing rotator or restricted
drive air
5. Defective Current to Pres-
sure Transducer
1. Defective brake solenoid
or brake valve assembly
tubing connection or com-
ponent (bells)
2. Improper rotator type DIP
switch setting on Atomizer
Card
3. Defective Current to Pres-
sure Transducer
1. No supply air to rotator or
control panel
2. Current to Pressure Trans-
ducer output (CL1-CL6)
disconnected or broken
Solution
3. Verify that the proper rotator type is selected
on the Atomizer Card DIP switches (see
Table 7).
4. Observe the Current to Pressure Transducer
output pilot pressure. If the pressure climbs
higher than normal or is maximum for an
extended period of time, then the drive air
signal to the rotator is restricted or the rotator
is failing.
5. If the Current to Pressure Transducer out-
put pressure is zero or lower than normal,
replace it.
1. Verify connection and operation of the brake
solenoid and valve assembly. Replace as
necessary.
2. Verify that the proper rotator type is selected
on the Atomizer Card DIP switches (see
Table 7).
3. Observe the Current to Pressure (I/P) Trans-
ducer output pilot pressure. If the pressure
is higher than normal or does not decline,
then replace the I/P Transducer. If the I/P
Transducer appears to be operating correct-
ly, then replace the 1:1 air piloted regulator.
1. Verify that supply air to the Control Panel
and air regulator assemblies is correct and
stable.
2. Connect or repair.
