INTRODUCTION
GENERAL DESCRIPTION
The PulseTrack 2 TM system is designed to contin-
uously monitor and maintain the program-mable
speed of up to six rotary atomizers and monitor tem-
perature and humidity for one or more zones. The
PulseTrack 2 system is a micro-processor-based
design that optimizes control of rotator speed
by utilizing proven proprietary software based
on many years of experience. This system can
monitor and control the speed of rotators offered
by Ransburg such as the TurboDisk TM , Aerobell TM
and Aerobell 33 TM family of applicators. The Pul-
seTrack 2 system is designed to be versatile and
adapt easily to system requirements.
Each PulseTrack 2 system includes a Control
Card and up to six Atomizer Cards for control of
rotator speed. There is one Atomizer Card for
each rotator. Each Atomizer Card includes a dig-
ital display for speed and diagnostic readout and
the necessary manual control switches required
to operate each rotator. Optional Temperature/
Humidity Cards display temperature and relative
humidity for signals received from remote mounted
probes. Additionally, discreet as well as analog
inputs and outputs are available for use in oper-
ating the system.
The basic components of the PulseTrack 2 system
are described below.
Control Card
The Control Card is a microprocessor-based
printed circuit board that performs the following
functions:
1. Communicates to each Atomizer Card through
a high-speed serial I/O data bus.
2. Receives external digital and analog control
signals from a system PLC or host controller and
processes the commands.
3. Receives the rotational feedback signals from
the integrated fiber optic receiver(s).
4. Receives analog signal feedback representing
temperature and relative humidity from a probe
located in a desired zone. The feedback signals
are scaled as needed and sent to each Tempera-
ture/Humidity Card to be displayed.
5. Performs the closed-loop rotational speed
computations for each atomizer. An output control
signal is generated and sent to the current-to-pres-
sure (I/P) transducers as needed to maintain the
desired speed.
6. Determines if there is a possible unsafe or
abnormal condition and automatically shuts down
the rotator and alerts the operator.
7. Supplies the signals to control each brake
solenoid for bell applications utilizing the brake
function.
8. The red LED1 flashing at upper left corner of
control card indicates the microprocessor is active.
Atomizer Card
The Atomizer Card (one per atomizer) provides
the operator controls necessary for basic speed
control operation of a given applicator and dis-
plays the speed and diagnostic information for
that atomizer.
Temperature/Humidity Card
(Optional)
The Temperature/Humidity Card provides a user
selectable display of temperature or relative hu-
midity for each remotely mounted probe. Degrees
Fahrenheit or Celsius can be selected.
Current-to-Pressure Transducer
A current-to-pressure (I/P) transducer is required
for control of each rotator. Based upon the error
between the present speed and the setpoint, an
electrical analog signal is generated from the Con-
trol Card. Each electrical signal is converted to a
