PulseTrack 2 Control Panel may require
exposure to potentials that can cause
SERIOUS BODILY INJURY or DEATH if
proper procedures are not followed. For
this reason, troubleshooting and field repair
should only be accomplished with specif-
ic test equipment by qualified electronics
technicians or authorized Ransburg repre-
sentatives.

"Safety" section of this manual must be
followed when troubleshooting.
Contacting Ransburg
Representative or Customer
Service
Before contacting your Ransburg repre-sentative
or the customer service department, be prepared
with the following specific information. This will
help resolve problems quicker.
• Control panel model number and serial
number.
• The basic system configuration including
type of applicators, coating used, etc.
• The type of problem that is occurring and
the frequency that it occurs, if applicable.
• Anything in the system that was changed
right before the problem started.
• Any troubleshooting that has already been
attempted.
BASIC SYSTEM
TROUBLESHOOTING
When tracing problems, refer to system installation
drawings, the "Control Panel Schematic in Figure
7", the "Troubleshooting Chart" in this section,
and the "Operation" and "Parts Identification" sec-
tions of this manual. The following section outlines
the most common problems encountered and
suggestions that may shorten the time involved
in troubleshooting the system. More detailed
information can be found in the "Troubleshooting
Chart" in the "Maintenance" section.
Most Common Problems
There are no adjustments on the Control Card per-
taining to speed control. The control parameters
are established for each rotator through software
based on switch settings. Once the system is
setup correctly and has been in operation, any
developing problems will be due to air leakage, a
component failure or a system application issue.
Troubleshooting a rotator speed control problem
generally consists of isolating the problematic
system component and replacing that component.
During troubleshooting, it is important to first rec-
ognize the possible fault modes and consider the
circumstances that might cause them. The most
common system problems and associated fault
modes are listed below:
Underspeed (uS) Fault:
1. Air supply to the system is not adequate.
2. Air leak in the system.
3. The rotator is damaged or failing.
4. The current to pressure transducer is not func-
tioning properly.
