Introduction
The PowerFlex 750-Series ATEX option module, installed in a PowerFlex
750-Series drive equipped with an 11-Series I/O option module, provides an
ATEX compliant safety function. This ATEX compliant function provides a safe
turn-off for equipment installed in a potentially explosive atmosphere according
to European Council Directive 94/9/EC.
The overall system includes an ATEX certified motor installed in a potentially
explosive atmosphere. The motor is equipped with a thermal sensor connected to
the ATEX option input. Do not install the drive in a potentially explosive
atmosphere. See Figure 1
WARNING: Risk of Explosion.
Do not install the PowerFlex 750-Series drive in a potentially explosive
atmosphere.
A drive installed in a potentially explosive atmosphere can cause an explosion.
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
ATEX certified motors equipped with either a thermostat or a PTC-type
thermal sensor.
ATT EN TI ON : 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.
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 can be the result of a broken wire, or an over-temperature condition in
the motor.
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 440. The ‘Mark A’ measuring circuit on the ATEX option
module is designed in accordance to IEC 60947-8 or EN 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.
10 Rockwell Automation Publication 750-UM003B-EN-P - July 2013
Loss of voltage to the measuring circuit also initiates the safe off function. This
voltage is sourced internally by the ATEX option module.

Risk Assessment Data
The PFD and PFH values in Ta b l e 1 were calculated based on equations in
IEC 61508. This table shows the worst case calculated values for drive frames
1…10 with a proof test interval of 20 years.
A proof test is not defined in this user manual. A proof test interval of 20 years
is used for the calculations here, signifying the product life span is 20 years.
These values show the SIL1 consumption of the ATEX safety function to be
approximately 30%. The safety calculations represent the local ATEX safety path
from the input of the ATEX daughter card to the device that disables
heat-producing power.

Safe State
Hardware Fault Tolerance
Safety Reaction Time
The safe state includes all operation that occurs outside of the other monitoring
and stopping behavior 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 is the minimum number of faults that can cause a loss of
the safety function as defined by IEC 61508-2. The overall ATEX function has a
hardware fault tolerance of zero.
If one fault occurs in the safety path, the safety function can become
compromised.
The safety reaction time is the amount of time from a safety-related event as
input to the system until the system is in the safe state.
The safety reaction time from an input signal trigger to the initiation of the
ATEX safety function is 30 ms (maximum) for PowerFlex 750-Series drives,
frames 1…10.

Setting the parameters to a different option can result in an explosion.
The following safe speed monitor parameters enable the ATEX function to
immediately remove power to the motor in case of a ATEX fault condition.
Yo u must set parameter 44 [Safe Stop Input] to one of these options:
• 1 - 2NC
• 3 - 1NC+1NO
Reset the Drive after an SSM Fault Detection
Interface Without a Safety Option
Yo u must set parameter 45 [Safe Stop Type] to one of these options:
• 0 - Torque Off
• 3 - Trq Off NoCk
The reset sequence depends on the configuration of the reset type for the SSM.
Follow these steps to reset the drive.
1. Clear the ATEX fault condition.
2. Issue a clear fault command.
3. Cycle the safety device wired to both channels of the safe stop input so that
both SS_IN_CHx inputs are cycled low to high.
If the SSM reset type is ‘automatic’, the drive is fully reset. Manual and
Manual-monitored modes require the reset input to the SSM card to be
either high, or cycled before the drive is fully reset.
The ATEX option module with the 11-Series I/O option module can be used
without a safety option with the safety signal on the backplane. The EnC and
EnNO contacts can be left un-wired.

Description of Functionality
Motors with Thermostatic Switches
Test the safety function for proper operation after initial installation and after the
drive system is modified. We recommend that functional testing be performed
annually during regular maintenance intervals.
WARNING: Risk of Explosion.
If any changes are made to an installed system, the operation of that system must
be verified. These changes include installation, removal, or modification of ATEX or
functional safety options. Failure to verify the operation of a completed installation
can result in a safety system that does not function correctly. See Verify Operation
on page 29.
The ATEX option module with 11-Series I/O option module provides ATEX
functionality for ATEX motors with thermostat contacts or PTC-type devices.
The module is designed to remove power from the gate firing circuits of the
output power devices (IGBTs) for the drive when the temperature circuit in the
motor indicates that the motor temperature is too high.
Thermostatic switches are arranged in series throughout the motor. Typically
there is a single switch, or a pair of switches, in each motor turn. Each switch
opens when the local temperature is too high. The ATEX option module with
11-Series I/O option module can detect an over-temperature event anytime the
circuit between the terminals is open.
