Table 4 shows an example of the device conflict text. A conflict can be
enunciated under these conditions:
• During power-up, when the ATEX safety configuration switch is set
improperly.
• If the ATEX option module with the 11-Series I/O option module is
installed in a slot other than 4 or 5.

Description/Corrective Action
xx011 PTC Over Temp
Resettable
fault
Coast
An over-temperature condition has been
detected in the motor, or the sensor path has
been broken.
xx012 PTC ShortCircuit
A short circuit condition has been detected in the
sensor path. If the fault is unable to be cleared,
make sure the thermal sensor that is connected
is a PTC-type and not thermostatic.
xx013 ATX VoltageLoss
Possible hardware damage.
A short in the motor to the thermal sensor.
An excess of electromagnetic compatibility
(EMC) noise due to improper grounding/
shielding.
xx014 ThermostatOvrTmp
An over-temperature condition has been
detected in the motor, or the sensor path has
been broken.
