General Problem
MASTER RUN
Switch Is Turned To
RUN, But The Rota-
tor(s) Do Not Turn
ON and No Faults
Occur
Rotator Speed Is Not
Stable
UNDERSPEED Fault
(uS)
(Continued On Next Page)
Procedure
1. Pneumatic or electrical
enable input missing or
defective
2. Improper rotary DIP switch
setting on Atomizer Card
1. Improper supply air to the
Control Panel and/or air
regulator assemblies
2. Improper rotator type DIP
switch setting on Atomizer
Card
3. Defective Fiber Optic
Receiver Module or cable
4. Defective Current to
Pressure Transducer
5. Pulsating enable or remote
analog speed setpoint
inputs
1. Insufficient supply air to the
Control Panel and/or air
regulator assemblies
2. Air leak in the system
Solution
1. Verify that there is a rotator enable air
signal to the corresponding enable input
(EN1-EN6) on the side of control panel or
a rotator enable electrical signal to the cor-
responding electrical enable input terminal
(J3-C15 to J3-C20).
Also verify that the ENABLE/DISABLE
switch located on the Atomizer Card is in
the ENABLE position.
2. Verify the rotary DIP switch setting (see
Figure 11) is the same as the slot number
of the Atomizer card as indicated by the
lable inside the cabinet door.
1. Verify that supply air to the Control Panel
and air regulator assemblies is correct
and stable.
2. Verify that the proper rotator type is selected
on the Atomizer Card DIP switches (see
Table 7).
3. Check that the red LED on the Fiber Optic
Receiver Module is ON and stable while
the rotator is turning. If not, replace fiber
optic cable or Receiver Module.
4. Check the output pilot pressure from the
transducer. If unstable, replace transducer.
5. Verify that enable and remote analog speed
setpoint signals are stable. The Active
LED located on the Atomizer card should
be stable and not blinking. Secure any
loose wiring and debug any system control
components.
1. Verify that supply air to the Control Panel
and air regulator assemblies is correct
and stable.
2. Locate leak and repair.
