DESCRIPTION OF SIGNALS ON TERMINAL BOARD
NAME MEANING CONNECTOR
VAC This is the control unit's power supply, which must be 24 Vac. The
power supply transformer should be at least 50 VA and must supply the
control unit only, in order to avoid possible sources of interference. 1
3
GND
Ground connection.
2
LOCK- / END-
LOCK+ / END+
This output is a polarized opto-electronic switch Max. 30 V/ 10 mA, and
is used for signaling when a cycle ends if END CYCLE is selected;
when LOCK in selected, the control unit gives an output signal from the
beginning of the welding process to the hold.
4
5
WRONG-
WRONG+ This output is a polarized opto-electronic switch Max. 30 V/ 10 mA, that
closes if the set current limits are not respected. The contact remains
closed for the HOLD and OFF time. A max. voltage of 24Vdc and a
maximum current of 0.1A can be applied to this contact. 6
7
COM2
TRIGGER Output of the trigger signal for the SCRs. Output is an impulse train
with a 5 KHz frequency, duty cycle of 16-20%, 30V amplitude on a load
of 35 S2. It is necessary to use the TECNA firing modules. 9

COM1
RIC5/PARITY This input, closed on COM1, can have two functions depending on the
choice made in the setup menu. The first function is external recall, the
second function is to control the parity during the recall. 11
12
RIC4
RIC3
RIC2
RIC1 These inputs are used to directly recall the welding program from an
external device. For a correct recall of the programs, these inputs
should be enabled before the start cycle signal. The inputs are active
when closed on the shared COM1. 13

16
COM1
START2_NO
Connect to the microswitches of the start cycle pedal. START2
determines the beginning of the work cycle of the second program
chosen during the programming operations. This input is active when
closed on the shared COM1.
17
19
AUX2 This input allows an external device to stop the welding cycle during
the squeeze phase. It can be used as an interlocking input or for
connecting safety devices such as for instance flow regulators or
pressure switches. The contact connected to it should be the normally
open type and is activated when closed on COM1. 18
START_NC Not used. 24
COM1
START-NO Connect to the microswitches of the start cycle pedal. The START
determines the beginning of the work cycle. This input is active when
closed on the shared COM1. 21
23
AUX
This input allows an external device to stop the welding cycle during
the squeeze phase. It can be used as an interlocking input or for
connecting safety devices such as for instance flow regulators or
pressure switches. The contact connected to it should be the normally
open type and is activated when closed on COM1.
22
START_NC
Not used.
24
BIC1_NO This input can be connected to the hand-operated start cycle push
buttons. The welding cycle starts when BIC1_NO and BIC2_NO are
closed simultaneously or closed in sequence within a maximum time of
0.5 secs. This value has been chosen in accordance to the
international safety rules. 25
BIC1_NC
COM1 Not used. 26
