iQ Series, Auto User’s Manual
Section 4 –System Operation
Five fault conditions are monitored by the iQ
Auto system for Any Fault:
• Average Overload
(Automatically resets on next cycle, or until an
activation of Fault Reset Input)
• Peak Overload
(Resets same as Average Overload)
• Overtemperature
(Automatically resets on cool-down)
• Power Not OK
(AC line voltage under 180VAC)
• Frequency Overload
(Automatically resets on next cycle, or until an
activation of Fault Reset Input)
iQ Auto System with MPC
Operational Test
Step 1. Verify that the system installation (with the MPC
option) is completed and all cables are connect-
ed.
Refer to the iQ Auto installation instructions in
Section 3, if needed.
Refer to Section 6 - Automation Interface - for in-
formation on wiring system controls, if needed.
Step 2. After completing Step 1, activate line power to the
standard iQ Auto system.
Normal Condition:
The POWER STATUS LED on the iQ Auto front
panel should light up GREEN.
The MPC module SYSTEM STATUS LED should
light up GREEN.
The system is ready to operate when both status LEDs
light up GREEN.
Troubleshooting Abnormal iQ Auto Sys-
tem Conditions
RED - If the POWER STATUS LED lights
up RED, check line voltage level.
GRAY - If the POWER STATUS LED is a
gray color (not lit), check line input.
Troubleshooting Abnormal MPC Module
Conditions
MPC Module SYSTEM STATUS LED is
ORANGE/YELLOW (resettable fault):
• Check for an iQ Auto 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 Sys-
tem.
• Resolve any iQ Auto power problem rst.
• There could be a circuit failure in the MPC
module. If a circuit failure is discovered, return
the MPC Module to Dukane for service.
Step 3. After completing Step 2, test ultrasound output
by activating I/O Connector Pin 12.
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.
