Chapter 1 Safety Concepts
Figure 1 - Basic ATEX Application
The ATEX option module monitors the thermal sensor in the motor. When the
thermal sensor reaches its trip point, the drive initiates a Safe Torque Off function
and removes torque-producing power from the motor. The ATEX safety
function has a safety integration level (SIL) capability limit of 1 according to
IEC 61508.
ATEX Function The PowerFlex 750-Series ATEX option module can be configured to support
Ex certified motors that are equipped with either a thermostat or a PTC-type
thermal sensor.
Thermostat Trip
When the circuit is configured to trip with a thermostat, the ATEX option
module supports a normally closed, dry-contact thermostat. The safe-off
function initiates when the ATEX option module detects that the contact is
open. This trip can be the result of a broken wire, or an over-temperature
condition in the motor.

ATTENTION: Risk of electric shock. If a motor insulation fault occurs, high
voltage can be present at the ATEX terminal block and wiring. Be sure that all
drive covers are installed when power is applied to the drive.

12 Rockwell Automation Publication 750-UM003G-EN-P - November 2022
Chapter 1 Safety Concepts
Positive Temperature Coefficient (PTC) Trip
When the circuit is configured to trip with a PTC-type thermal sensor, the
ATEX option module supports sensors with characteristics according to
DIN 44081/DIN 44082. The ‘Mark A’ measuring circuit on the ATEX option
module is designed in accordance to EN/IEC 60947-8. This circuit trips when
the motor temperature has reached its trip point, or an open-wire/short-circuit
condition is detected in the sensor circuit.
Loss of voltage to the measuring circuit also initiates the safe-off function. The
ATEX option module internally sources this voltage.
Figure 2 - ATEX Circuitry
Safe State The safe state includes all operation that occurs outside of the other monitoring
and stopping behavior that is defined as part of the ATEX option module. The
ATEX safety function, as provided by the ATEX option module, places the drive
in a safe state by removing the power from the gate firing circuits of the output
power devices (IGBTs).
Hardware Fault Tolerance Hardware fault tolerance is the minimum number of faults that can cause a loss of
the safety function as defined by EN 61800-5-2 and IEC 61508 Part 2. The
overall ATEX function has a hardware fault tolerance of zero.

ATEX Option Module and 11-Series I/O Option Module without a
Safety Option Module
To configure the ATEX option module with 11-Series I/O option module for
use without an additional safety module, follow these steps.
Normally you can only use one safety option module at a time on a drive. If you
use two safety cards in a drive, a device conflict occurs. However, the ATEX
option module with 11-Series I/O option module can have one additional safety
module configured for use simultaneously, see ATEX Option Module and 11-
Series I/O Option Module with a Safety Option Module.
1. Set switch S1-1 to ON.
2. Set switch S1-2 for Thermostat mode or PTC mode.
3. Install the safety enable jumper on the main control board.
Switch Setting Description
S1-1 ON Configures the ATEX option module for use without an additional
safety option module.
S1-2 OFF Configures the ATEX option module for Thermostat mode,
over-temperature monitoring.
Can be used with PTC-type thermal sensors if short circuit
monitoring is not needed.
ON Configures the ATEX option module for PTC mode.
Provides both over-temperature and short circuit monitoring.
IMPORTANT The default setting of the safety enable jumper = installed.
For this step, verify that the safety enable jumper is installed.
