STOP MAXIMUM
CURRENT LIMIT
28 The control unit counts some faulty
spots, the last of which has been
carried out with a current value
higher than the max. set limit. Clear the error by pressing any
key. See chapter "CURRENT AND
CONDUCTION ANGLE LIMITS"
STOP MINIMUM
CONDUCTION LIMIT
29 The control unit counts some faulty
spots, the last of which has been
carried out with a conduction
angle value lower than the
minimum set limit. Clear the error by pressing any
key. See chapter "CURRENT AND
CONDUCTION ANGLE LIMITS"
STOP MAXIMUM
CONDUCTION LIMIT
30 The control unit counts some faulty
spots, the last of which has been
carried out with a conduction angle
value higher than the max. set
limit. Clear the error by pressing any
key. See chapter "CURRENT AND
CONDUCTION ANGLE LIMITS"
NO CURRENT SIGNAL 31 During the last welding cycle there
was no secondary current
circulation in the machine. Check for continuity of the
secondary circuit. Check the
electric wiring of the current
transducer.
CHANGE AMMETER
CAPACITY
32 The welding process is being
performed in constant current or
with a power percentage using an
ammeter capacity different from
the one set in the self learning
procedure. Change the ammeter capacity or
change the program parameter to
select a different work mode.
NO EMERGENCY
SIGNAL
33 The emergency signal, required for
operating the control unit, is
missing. Ensure that the emergency contact
is closed.
ZERO SPOTS
COUNTER? KEY[-]
=YES
34
The CLEAR key was pressed to
zero the number of spots and the
control unit requests confirmation. Press the key [-] to clear the spots
counter, otherwise press any other
keys or wait a few seconds.
ACCESS CODE 35 Someone is trying to access the
menu restricted to installers. Enter the access code if known.
Otherwise wait a few seconds.
CODE ERROR
NO ENTRY
36
Someone is attempting to enter the
installers-only menu without
knowing the access password.
PULSES > MAX.
WELDING TIME
37 The total pulse welding time is
higher than the maximum value of
125 periods. Decrease the pulse welding time
or the number of impulses.
PRESSURE
xx.x Bar 38 The measured and displayed
welding pressure is not within the
limits set in the execution program. Check the air feed circuit or
change the pressure limits in the
program.
ERROR!!
SAFETY RELAY
39 The safety relay that supplies the
control unit’s outputs is faulty
STEPPER FUNCTION
NOT ACTIVE
40 The stepper function is not active
and therefore any data entered in
the associated menu have not
been accepted. In order to activate the stepper
function, check the set data and
make sure that there are no
inconsistencies.
