Ransburg PulseTrack2 A11515-XXXXX - Manual (Page 43)

Overspeed (oS) Fault:
1. The braking air solenoid is not functioning
properly.
2. The brake air line has lost connection to the
rotator.
3. The brake air valve is defective.
4. The current to pressure transducer is not func-
tioning properly.
Loss of Feedback (LF) Fault:
1. Supply air to control panel or rotator turned off.
2. Pneumatic transducer output (CL1 - CL6) dis-
connected.
3. Fiber Optic Cable is damaged or not connected.
4. Faulty air volume booster.
5. Transducer electrical input disconnected or
faulty transducer.
6. Faulty Control Card.
7. Faulty Fiber Optic Receiver module.
8. The rotator has seized and will not spin.
Invalid Speed Request (In) Fault:
1. Speed setpoint set too high.
2. Defective atomizer card (local mode).
3. Defective analog input source (remote mode).
No Connection (nc) Fault
(Temperature/Humidity Card):
1. Loose or defective cable connection between
control panel and Temperature/Humidity Probe.
A speed control problem may be associated with
any of the components that make up the entire
system. First, try to isolate generally, where in
the system the problem lies. If the same problem
is occurring on more than one rotator, inspect
those system elements that are common to all
the problem rotators. This includes the air supply
pressure to the control panel as well as the re-
motely mounted air piloted regulators. This also
includes the Control Card, 24VDC power supply,
front panel switches, fuses, AC line filter and any
wiring associated with them.
If the problem occurs on one rotator but not oth-
ers, inspect those system elements that are spe-
cific to each rotator. These include the Atomizer
Cards, current to pressure transducers, pressure
switches, Fiber Optic Receiver Modules, brake
valves, brake solenoids and any wiring or tubing
associated with them.
