MESSAGE DESCRIPTION
CORRECTIVE ACTION
(IF REQUIRED)
TYPE OF
MESSAGE
INPUT TOO LARGE
The user has attempted to program
a weld energy or time that exceeds
the capability of the Power
Supply.
Re-program welding parameters to be
within the capability of the Power
Supply.
GENERAL
STATUS
INPUT TOO SMALL
The user has attempted to program
a weld energy or time that is below
the capability of the Power
Supply.
Re-program welding parameters to be
within the capability of the Power
Supply.
GENERAL
STATUS
LOWER LIMIT
GREATER THAN
UPPER LIMIT
The user has tried to program a
Lower Limit value that is greater
than the Upper Limit value for
Pulse 1 or Pulse 2 time periods.
Re-program the invalid Lower Limit
value. GENERAL
STATUS
NO CURRENT
READING
No current measurement was
made. Possible open circuit.
Check that a closed secondary circuit is
present when the Power Supply fires.
If message persists, possible blown
internal fuse on Capacitor Charging
Power Supply, contact AMADA
WELD TECH for support. OUT OF
LIMITS
NO VOLTAGE
READING
No voltage measurement was
made. Possible open circuit or
possible voltage lead connection
problem.
Check that a closed secondary circuit is
present when the Power Supply fires.
Check voltage cable connection.
If message persists, possible blown
internal fuse on Capacitor Charging
Power Supply, contact AMADA
WELD TECH for support.
OUT OF
LIMITS
POWER 1
GREATER THAN
UPPER LIMIT
Actual weld power is greater than
the user set Upper Limit value for
Pulse 1.
Determine the cause of the high power.
Changes to the welding setup or
process can affect the energy delivered.
Refer to the Troubleshooting Chart in
Chapter 6. Limits should be set by
qualified by personnel and are
designed to identify process variations.
OUT OF
LIMITS
POWER 1 LOWER
THAN LOWER
LIMIT
Actual weld power is less than the
user set Lower Limit value for
Pulse 1.
Determine the cause of the low power.
Changes to the welding setup or
process can affect the energy delivered.
Refer to the Troubleshooting Chart in
Chapter 6. Limits should be set by
qualified by personnel and are
designed to identify process variations.
