TROUBLESHOOTING
Contacting your Ransburg Repre-
sentative or Ransburg Customer
Service
Before contacting your Ransburg repre-sentative
or the customer service department, be prepared
with the following specific information that will help
resolve problems quicker.
• Control panel model and serial numbers.
• The basic system configuration including typeof
applicators, coating used, etc.
• The type of problem that is occurring and the
frequency that it occurs if applicable.
• Anything in the system that has changed when
the problem started.
• Any troubleshooting that has already been
attempted.
Basic System Troubleshooting
When tracing problems, refer to the control panel
schematic in Figure 5, the Troubleshooting Guide
in this section, the “Operation” section, and the
“Parts Identification” section of this manual. The
following section outlines the most common prob-
lems encountered and gives suggestions that may
shorten the time involved in troubleshooting the
system. More detailed information is offered in
the troubleshooting guide.
Most Common Problems
Most problems encountered with the high voltage
supply do not involve faulty equipment but are
attributed to one of the following:
1. Coating/paint buildup or residue on system
components
2. Fluid supply or dump lines
3. Improper part grounding
4. High voltage cable failure
5. Improper power supply overload setting or
system interface problems
If a high voltage output problem is suspected
such as low output voltage, no voltage, or re-
peated overloads, perform the following basic
trouble-shooting procedure.
Equipment Required: Ransburg High Voltage
Test Probe and Meter (76652-01) and an AC
RMS Voltmeter.
A high voltage problem may be associated with
any one of the components that make up the entire
electrostatic system. First, try to isolate generally
where in the system that the problem lies.
>
Field repair and troubleshooting of
the Voltage Master 2 system 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.
>
All safety precautions listed in the
"Safety" section of this manual must be
followed.
>
Field repair of the Power Supply tank is
NOT to be performed unless by specifically
trained and qualified Ransburg personnel
with access to instrumentation that is certi-
fied traceable to NIST standards. Removal
of the lead seal located on the power sup-
ply tank voids warranty unless the above is
followed.
