ATEX Monitoring
This section describe the parameter 41 [ATEX Sts] bit functionality, the ATEX
faults and configuration errors, and how to restart the drive after an
over-temperature fault.
Parameter 41 [ATEX Sts]
Parameter 41 [ATEX Sts] appears in the 11-Series I/O file, Motor PTC group,
when the ATEX option module is installed.
This parameter provides the current status of the ATEX thermal sensor. If an
ATEX fault occurs, the corresponding bits change. When the temperature falls
below the trip point, the bits change back to their original settings.
A descriptive fault message is displayed. The fault message can be retrieved from
the fault queue after you clear the fault message from the display.

This parameter is not latched and only displays the current status of the ATEX thermal sensor. When an ATEX fault is present, the corresponding bit value is 1. When
motor temperature is within the optimal range, the bit value is 0.
This parameter is available only when an ATEX option module is installed.
Bit 0 “Thrmlsnsor OK” – Thermal sensor is Ok.
Bit 1 “Short Cirkt” – Short circuit fault detected by thermal sensor.
Bit 2 “Over Temp” – Over temperature fault is detected by thermal sensor.
Bit 3 “Voltage Loss” – Voltage loss fault has taken place on ATEX board.
Bit 13 “Thermostat” – Thermostat input has been selected.
Bit 14 “PTC Selected” – PTC input has been selected.
