1
The discrete connection for this input is always required, even when the I/O source is Modbus
or EtherNet/IP.
2
The signal from the discrete interface is always used, even when the I/O source is Modbus or
EtherNet/IP where there is no equivalent signal.
3
Momentary operation will reset all expired counters. If maintained for more than 5 seconds all
counters will be reset, regardless of status.
4
Momentary operation will reset all expired steppers. If maintained for more than 5 seconds all
steppers will be reset, regardless of status.
5
The Edit enable function is only available on the Discrete interface. This bit is always P128 on
other interfaces.
5.2. Outputs
Output AWS
designation
Description
EOS EH1 This output switches on to indicate the end of the weld
sequence.
HAV RV1 Used in conjunction with the Retract input to control
the welding head.
Fault FT1 This output indicates a fault condition.
Ready
1
This output is active if iPAK2 is ready to weld. The output
switches off under some fault conditions.
Contactor MC1 This output can be used to control an isolation
contactor.
Counter /
tip dress request
This output indicates that the counter has reached its
limit or that a tip dressing operation is required.
Stepper This output indicates that the stepper has reached its
limit.
Pre-warn This output indicates that the stepper is close to its limit.
AV8 Additional outputs that can be used during the weld
sequence to control valves etc.
AV7
AV6
AV5
AV4
AV3
AV2
AV1

If iPAK (v1) mode is selected (see Configuration)
the sense of the READY output is reversed and it signifies NOT READY
outputs AV4, 5, and 6 are used for MUX selection and are not available
5.3. Softstart
Some configurations offer a Softstart feature. This works by sending a software command to
start a weld program. Be aware that if the hardware START input is not closed, then AV1-8
cannot operate and hence anything connected to these outputs will not work. Examples
include:
Any air-valve including WAV.
Transformer selection using an external decoder in iPAKv1 mode.
