BIC1 NC / RIC 5
This input may be left unused or may be used either as a NC input for the
button BIC1 or as recall RIC5.
27
D STROKE
This input is used to manually control the double stroke in welders fitted with
this function.
28
BIC2 NC / RIC 6
This input may be left unused or may be used either as a NC input for the
button BIC2 or as recall RIC6.
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, that is to say 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 welding cycle during the
squeeze phase. It may be used as an interlock input or to connect safety
devices such as flow meters or pressure switches. The contact connected to it
must be the NO type and is activated closed on the 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.
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 board 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 cut-off voltage to all outputs.

ROG
AGND
This analogue input is not used.
51
SHIELD
Shield for transducer cable.
