+24VP
+24V reported to GNDP max 250 mA
PWR
2
EMERGENCY
Emergency signal causes the block of power supply coming
from the welding cycle and prevent the reactivation of the
same, turn off all outputs and reset valve by removing all
power from the output drivers.
I
3
Pb Com
Common signal for start concurrently with the buttons start
cycle (PUA, PUB and PU-Stroke)
I
4
Pb A
Signal in conjunction with Pu com in spot mode allows the
start of the welding cycle 1, in seam mode allows the cycle
start to coincide with the current 1.
I
5
Pb B
Signal in conjunction with Pu Com in spot mode allows the
start of the welding cycle 2, in seam mode allows the switch
to the welding current 2.
I
6
Pb C
In spot mode signal that allows for the early termination of the
spot welding time to achieve thickness, in seam mode allows
the switch to the welding current 3.
I
7
Pb- PRE-STROKE
(Pb D)
Activation and deactivation signal of the pre stroke valve
output.
I
8
P-SW (AUX)
Auxiliary signal, in spot mode, if not present, it will freeze the
welding cycle before or after squeeze, in seam mode, if not
present, it freeze the welding cycle waiting the closure of the
roller motor relè prior to entry into welding.
I
9
Current ON-OFF
Signal that in spot mode enables the current flow during the
hot cycles only before to enter in welding cycle, in seam-
mode enables or disable the current flow during welding cycle
before and during cycle
I
10
Reset Alarms
Signal silence alarms and reset the READY condition
I
11
Reset Steps
Signal of zero steps of current, confirming the completion of
the return electrodes. The use of this signal is compared to the
use of alternative equivalent function terminal.
