deactivated again the next time the entire system is restarted.
• C4C6: Water pump power supply unit. Two 12 V power supplies (60 W each) are operated in series for the power
required by the water pump (80 W at 24 V DC). These power supply units are only connected if needed (on primary
side). Both LEDs light up when the water pump should be running. If only one LED lights up, a power supply unit is
defective. The pump supplies water, but an error message appears due to the low current level.
• C5: Water pump ON. ON signal for the water pump from digital output of the control computer to the semi-con-
ductor relay which switches on the power supply unit of the pump. The LED lights up if the water pump should be
running.
• C7: Signal from external sensor. The LED indicates the status of an external device; it lights up if the status is "
OK
".
The machine features a connection for an external sensor, e.g. for the connection of a residual oxygen meter (ORB).
Devices which are to be monitored for their status before welding begins can be connected here. The function must
be activated via the menu item "
System settings
" > "
System adjustments
".
• C8: Not used (reserved).
• D1: Gas valve ON. This signal (PC digital output) switches the internal gas valve. If the LED does not light up, there
is probably an error in the control computer.
• D2/D3: Fan operation – OM 165 CA: Two fans featuring speed feedback are installed on the heat exchangers in
these units. The LED indicates whether the fans are running. When using external water cooling (e.g. compressor
cooling or from other manufacturer), these indicators do not have a function and are always off.
• D4: Start/Stop button. LED lights up when the button on the weld head is pressed. If the machine does not respond
to this command, you can check whether the signal is arriving or the button on the weld head is defective. The
check only makes sense if the voltage supply for the weld head is functioning (see LED B1).
• D5: Gas-test button. LED lights up when the button on the weld head is pressed. If the machine does not respond to
this command, you can check whether the signal is arriving or the button on the weld head is defective. The check
only makes sense if the voltage supply for the weld head is functioning (see LED B1).
• D6: Motor button. LED lights up when the button on the weld head is pressed. If the machine does not respond to
this command, you can check whether the signal is arriving or the button on the weld head is defective. The check
only makes sense if the voltage supply for the weld head is functioning (see LED B1).
• D7: 0-position (home) button. LED lights up when the button on the weld head is pressed. If the machine does not
respond to this command, you can check whether the signal is arriving or the button on the weld head is defective.
The check only makes sense if the voltage supply for the weld head is functioning (see LED B1)..
• D8: 0-position (home) switch. LED lights up when the home position is reached (for weld heads with limit switch).
In case of problems with the return or during a motor calibration, you can determine whether the limit switch in the
weld head is working.
• E1: Motor relay ON. LED lights up if one of the two motors should be running. This function is used to switch off all
motor lines (rotation, tacho and wire) running to the weld head during ignition for reasons of interference resis-
tance. The signal is a direct digital output of the control computer. If the LED is not lit up, the motors cannot run.
There is probably a defect in the control computer.
• E2: Orbitwin switching. This signal is only relevant for a connected ORBITWIN and indicates switching between
the two weld locations. The LED lights up if weld location 2 is selected. In the power source, this signal is used to
switch between the two procedures.
• E3 - E7: Head code, bit 0 - 4. The LEDs indicate the current present head code of the connected weld head (these
are the bridges presented in the control plug or weld head). The indicator only works if the voltage supply for the
weld head (B2) is active. The LEDs can be referred to for error analysis if the system detects a connected weld head
incorrectly or not at all.
• E8: Encoder interface. LED signals the presence of a supplementary PCB which permits the operation of weld heads
with digital encoder feedback. The LED only lights up if a corresponding weld head is connected. On standard ma-
chines, the LED is off.
