Instruction manual
85/92
26
RIC6 - BIC1 NC
This input closed on COM1 can have
different
functions according to the
choice made in the
SETUP
menu: either as direct recall of the welding
programs from an external device or it is used to check the normally closed
contact of the hand-operated push buttons. The input is activated when closed
on the COM1.
27
D. STROKE
This input is used to manually control the double stroke in welders fitted with
this function.
28
RIC7 - BIC2 NC
This input closed on COM1 can have
different
functions according to the
choice made in the
SETUP
menu: either as direct recall of the welding
programs from an external drive or it is used to check the normally closed
contact of the hand-operated push buttons. The input is activated when closed
on the COM1.
29
COM1
Common for inputs with 24VDC reference.
30
31
TERM
FLUX/TERM
This input is used to connect a thermostat (pin 30). If a flow meter is also
present, it must be connected in series with the thermostat, i.e. the thermostat
with pin 30-31 and the flow meter with pin 31-32.
32
COM1
Common for inputs with 24VDC reference.
33
AUX3
This input allows an external device to stop the weld cycle during the squeeze
stage. It may be used as interlocking input or to connect safety devices such as
for instance flow meters or pressure switches. The contact connected to it must
be the normally open type and activates closed on COM1.
34
COM1
Common for inputs with 24VDC reference.
35
BIC2 NO
Input for manual cycle-start buttons. The weld cycle begins when BIC1 NO and
BIC2 NO close simultaneously, or in sequence within a max time of 0.5
seconds.
36
COM1
Common for inputs with 24VDC reference.
37
VAUX
This is a 24VDC output and indicates that the control unit is powered-on and
ready to receive a cycle-start command. This output may be used to connect a
valve intended for the welder's supplementary services. Command suitable for
coil control at 24VDC. Max. 5W.
38
EV1
Connect to the solenoid valve that actuates the main cycle. Command suitable
for coil control at 24VDC. Max 5W.
39
COM2
Common for outputs with 0V reference. Connected to GND conforming to
regulation EN60204.
40
EV2
Connect to solenoid valve 2 (BACK PRESSURE). Command suitable for coil
control at 24VDC. Max 5W.
41
COM2
Common for outputs with 0V reference. Connected to GND conforming to
regulation EN60204.
42
EV3
Connect to solenoid valve 3 (FORGE). Command suitable for coil control at
24VDC. Max 5W.
In case the TE550 is set to SEAM WELD mode, this output controls the seam
start (MOTOR DELAY parameter).
43
COM2
Common for outputs with 0V reference. Connected to GND conforming to
regulation EN60204
44
EV4
Connect to solenoid valve 4 (DOUBLE STROKE). Command suitable for coil
control at 24VDC. Max 5W.
45
46
EV PROP-
EV PROP+
This is an output for the connection with the card that controls the proportional
valve.
47
48
EMERGENCY
EMERGENCY
Emergency input. An emergency button may be connected to these inputs, the
contacts of which must open if a fault occurs. The emergency procedure and
consequently the opening of these inputs cutoff voltage to all outputs.
49
50
ROG
AGND
The current transducer (or Rogowski loop) must be connected to this analog
input.
51
SHIELD
Shield for transducer cable.
NOTE: The EV1, EV2, EV3, EV4, TRIGGER outputs are protected against short-circuit with
automatically restorable electronic elements.
