Section 3 - General Information: Troubleshooting
Over Pressure Problem Correction
1.
Determine if the problem is high pressure related.
2.
Relieve system material pressure.
3.
Turn off main power.
4.
Fix the problem area:
a. Potential high pressure causes:
-Restriction
-Overheating material in static position
-ISO filter at gun
5.
Re-start system for operation
Once the power has been turned off and problem
solved, and the main power is turned on again, the
over pressure lighted buttons will automatically be
reset.
If you do not understand the electrical hook-up de
scribed above, consult your local GlasCraft distributor
OR a qualified electrician.
It is recommended that a qualified, licensed electrician
should install power to the supply disconnect.
You should always follow all local or national electrical
codes.
Disconnect power source BEFORE attempting any re-
pairs or opening the Control Boxes. Access to internal
parts is limited to qualified personnel ONLY!
Place Main Power Switch in OFF position BEFORE dis-
connecting power cables. This equipment is not
approved for use in hazardous locations as set forth in
the National Electrical Code Article 500 and Sub-Part “S”
of the OSHA Standards.
Material Or Mechanical Problem
Troubleshooting Procedure
By following this procedure, you should be able to
locate and cure problems easily. Remember, however,
that a successful operator must know:
• WHAT GOOD MATERIAL LOOKS LIKE.
• HOW THE EQUIPMENT NORMALLY OPERATES.
• WHAT PATH THE MATERIALS FOLLOW THROUGH
THE EQUIPMENT.
• KNOWLEDGE OF THESE TROUBLESHOOTING
PROCEDURES.
Always start with step one, never skip any portion of
these procedures. The material pressure gauges are to
be used for troubleshooting purposes only. The
pressures registered on one gauge will not necessarily
match the other. This difference can be caused by
variance in materials, temperatures, viscosities, etc.
1.
Identify the missing material.
2.
Check the material pressure gauge on the
missing material side.
a. If the missing material gauge reads HIGHER than
normal, there is a RESTRICTION problem
between the gauge and the Mixing Chamber tip
in the Gun.
b. If the missing material gauge reads LOWER than
normal, there is a STARVATION problem between
the gauge and the material supply system.
Problems may be cyclic in that they will appear first on
only one stroke of the Proportioning Pump. Check the
pressure gauges during one of these bursts of missing
materials and always stop spraying while you are
getting a burst of good material.
3.
Concern yourself only with the material pressure
on the missing material side. In troubleshooting a
STARVATION problem where the pressure gauge
on the missing material side is LOWER than normal,
start at the point farthest from the unit and work
forward. Check the obvious and easy things first.
