ITEM TE550
Instruction manual
89/92
ERROR CURRENT
OVERFLOW
114
A weld was carried out with a
current signal that was too high.
Select, if possible, the higher
ammeter rate. Check for the
correct connection and position of
the current transducer.
VOLTAGE ERROR
OVERFLOW
115
During the last weld cycle the
upper electrodes voltage limit
was overrun. It is advisable to
change the voltage range on
card 50097.
Check the wires connection at the
weld transformer secondary and
the rate of the isolating
transformer on card code 50097.
SPOTS FINISHED
DRESS ELECTRODES
116
The maximum number of welds
was attained without having
cleared the DRESSINGS ALARM
output.
Clear the error, carry out the
electrodes dressing procedure and
then activate the dressing-done
signal.
ELECTRODE END LIFE
REPLACE WITH NEW
117
The maximum number of welds
was attained without having
cleared the ELECTRODES END
LIFE ALARM output.
Clear the error, change the
electrodes and then activate the
change-done signal.
START RELEASED!
SPOT NOT FINISHED
118
With parameter AUTORETAIN
set to OFF, the cycle-start signal
was issued before the weld
ended.
Clear the error to continue.
POSITION SENSOR
ZERO PROCEDURE
119
The QUALITY - T function was
activated during a weld
programme but the coordinate
zeroing procedure was not
carried out.
Set the QUALITY - T parameter to
ZERO and carry out a weld
without material between
electrodes to define the ZERO
coordinate. Then restore the
original value of the QUALITY-T
parameter.
POSITION SENSOR
QUOTE FAIL
120
Error during the calculation of the
position sensor coordinate
measurement.
Ensure the sensor is powered and
that the CAN cable is plugged in
correctly.
Contact service center.
POSITION ERROR
MODIFIED STRUCTURE
121
Error when the position sensor
measured the coordinate, the
electrode has worn out or the
geometry of the spot welder
structure changed.
Check for the absence of
anomalous movements in the
spot welder structure.
Clear the error and repeat the
coordinate zeroing procedure.
POSITION SENSOR
FAIL COMUNICATION
122
Position sensor communication
error.
Check that the position sensor has
been wired correctly.
Contact service center.
POSITION SENSOR
NOT PROGRAMMABLE
123
The CAN card coded 50274 was
not detected at switch-on.
Check that the CAN is properly
connected to the TE550 control
unit.
THICKNESS
UNDER LOW LIMIT
124
The initial thickness of the sheets
in between the electrodes is less
than that set in the THICK. MIN
limit.
Reset the error and check the
material between the electrodes.
