4.1.8.1
Initiator „Head back”
Function:
Head back
Order no.: 770.61303
Type:
PNP, break contact, NC
Working triggering distance S
n
:
0,8 mm
Voltage range +V
s
:
24 V DC
Rated operational current:
100 mA
Voltage drop static max.:
3 V
Schematic:
The initiator “Head back” should always be set so that the LED illuminates as soon as
the motor head is in basic position.
This signal is evaluated during an automated sequence.
4.1.8.2
Initiators „Stroke Cylinder forth“ and „Stroke Cylinder back
Function:
Stroke cylinder forth / stroke cylinder back
Order no.: 770.61293
Type:
PNP, make contact, NO
Working triggering distance S
n
:
0,8 mm
Voltage range +V
s
:
24 V DC
Rated operational current:
100 mA
Voltage drop static max.:
3 V
Schematic:
The initiator “Stroke Cylinder back” should always be set so that the LED illuminates as
soon as the stroke cylinder is in basic position.
This signal is evaluated during an automated sequence and signalizes the end of the
welding process.
The initiator “Stroke Cylinder forth” should always be set so that the LED illuminates as
soon as the stroke cylinder reaches its upper stroke position.
This signal is evaluated to adjust the weld head.
