Section 4 –System Operation
Dukane Manual Part No. 403-591-01
An Overload Fault latches until the next time U/S
is activated.
Any Fault
status activates when any fault is de-
tected by the system. It latches until the start of the next
cycle, unless it is activated due to Overtemperature or
Power Not OK fault.
Five fault conditions are monitored by the iQ
Auto-Plus system for Any Fault:
•
Average Overload
(Automatically resets on next cycle)
•
Peak Overload
(Resets same as Average Overload)
•
Overtemperature
(Automatically resets on cool-down)
•
Power Not OK
(AC line voltage under minimum voltage)
•
Frequency Overload
(Automatically resets on next cycle)
iQ
Auto-Plus System with
MPC Module Operational Test
1. Verify that the system installation (with the MPC op-
tion) is completed and all cables are connected.
Refer to the iQ Auto-Plus installation instructions in
Section 3, if needed.
Refer to
Section 6 - Automation Interface
- for infor-
mation on wiring system controls, if needed.
2. After completing Step 1, activate line power to the
standard
iQ
Auto-Plus system.
Normal Condition
:
The POWER
LED
on the iQ Auto-Plus front panel
should light up GREEN .
The STATUS
LED
on the
iQ
Auto-Plus front panel
should light up GREEN.
The MPC module SYSTEM STATUS
LED
should
light up GREEN .
The system is ready to operate when all status
LED
s
light up GREEN .
Troubleshooting Abnormal
iQ
Auto-Plus
System Conditions
POWER
LED
RED - If this
LED
lights up RED, check line
voltage level.
GRAY - If this
LED
is a gray color (not lit),
check line input.
STATUS
LED
Not Green - If the status
LED
is not GREEN, refer
to Table 4-I for more information.
Troubleshooting Abnormal MPC Module
Conditions
MPC Module
SYSTEM STATUS
LED
is
ORANGE / YELLOW
(resettable fault):
•
Check for an
iQ
Auto-Plus overload on the
previous welding cycle.
•
Check for an invalid channel selection input
control code - selection code is greater than the
number of installed channels.
MPC SYSTEM STATUS
LED
is RED (non-recov-
erable fault.
Check for POWER OK fault on the iQ Auto-Plus
System.
•
Resolve any
iQ
Auto-Plus power problem first.
•
There could be a circuit failure in the MPC
module. If a circuit failure is discovered, return
the MPC Module to Dukane for service .
3. After completing Step 2, test ultrasound output by
activating system I/O Connector Pin 13.
Normal Condition :
The system is operating properly when power is
delivered to the attached stack.
Ultrasound Activation Connections
:
Usually an automated control system is wired
to this control input.
Optionally
- A manual switch could be wired
to this control input.
