is detailed in the Trouble Shooting Manual. Warning: Further
use of robot is not permitted until the fault is found and
eliminated.
37043, Safety signals overloaded
Description
The AC_ON or SPEED signals draw too much current.
Consequences
The safety system shuts down the signals, causing the system
to go to either system failure state (for AC_ON) or status SYS
HALT (for SPEED).
Probable causes
A load connected to the circuit may be too high, or the safety
system may be malfunctioning. See the circuit diagram!
Recommended actions
Check all loads connected to the AC_ON and SPEED circuits.
Check the safety system cabling and connectors, and replace
any faulty unit if required.
37044, Overload on Panel Board digital output
signals
Description
The panel board user digital outputs draw too much current.
Consequences
The panel board shuts down the signals, causing the system
to go to status SYS HALT.
Probable causes
A load connected to the circuit may be too high, or the panel
board may be malfunctioning. See the circuit diagram!
Recommended actions
Check all loads connected to the user digital outputs. Check
the panel board cabling and connectors, and replace any faulty
unit if required.
37045, Faulty external computer fan
Description
The external computer fan in the control module spins too
slowly.
Consequences
No system consequence. The control module temperature will
rise.
Probable causes
Faulty fan, cabling or power supply. See the circuit diagram!
Operating manual - Troubleshooting IRC5
3HAC020738-001 Revision: AA
Recommended actions
Check the cabling to the external computer fan. Check the fan,
and replace any faulty unit if required.
37046, Safety signals overloaded
Description
The 24 V PANEL supply draws too much current.
Consequences
The safety system shuts down the signal, causing the system
to go to status SYS HALT.
Probable causes
A load connected to the circuit may be too high, or the safety
system unit may be malfunctioning. See the circuit diagram!
Recommended actions
Check all loads connected to the 24V PANEL circuit. Check
cabling on the safety system.
37049, Activation contactor activation error
Description
The activation relay for mechanical unit arg failed to close.
Consequences
The mechanical unit cannot be run manually or automatically.
Probable causes
The activation relay configured within the system may be faulty,
or the system may not be configured correctly.
Recommended actions
Check the contactor and make sure its connections are
connected correctly. Check the system motion configuration
regarding the activation relay. How to check the configuration
file is detailed in the Trouble Shooting Manual.
37050, Overtemperature in main computer
Description
The temperature in the main computer unit or the main computer
processor is too high.
Consequences
The system might get damaged.
Probable causes
The unit may be overloaded, its fans may be malfunctioning or
the air flow may be restricted.
Recommended actions
Make sure the fans are operating. Check that air flow to the unit
fans is not restricted.
