Safety
This device is intended to be part of the safety-related control system of a
machine.
Safety Notes
Before installation, perform a risk assessment to determine whether the
specifications of this device are suitable for all foreseeable operational and
environmental characteristics of the machine to which it is to be fitted. At regular
intervals during the life of the machine, check whether the characteristics
foreseen remain valid.
ATTENTION: Danger of serious injuries.
Misuse can result in malfunction.
• Only authorized and trained personnel must start up,
assemble, install, manipulate, or retrofit the device.
• Installation must be in accordance with these instructions.
• Do not defeat, tamper, remove, or bypass this unit.
Rockwell Automation cannot accept responsibility for failure of this device if the
Page
procedures given in these instructions are not followed or if it is used outside the
1
recommended specifications in these instructions.

IMPORTANT The safety inputs of these products are described as
1
normally closed (N.C.), that is, with the guard closed, the
2 actuator in place (where relevant) and the machine able to
be started. Exposure to shock and/or vibration in excess
2
of what is stated in IEC 60068 part: 2-6/7 must be avoided.

If there is any malfunction or damage, do not attempt to repair. The unit must be
replaced before machine operation is allowed.
Functional Description
Page
The unit is enabled once the supply is powered up and the safety circuits are
4
closed. The PWR status indicator is on.
A valid reset operation activates the safety outputs. The CH1 and CH2 status
indicators of the output illuminate. At the demand of the safety function and if any
fault occurs, the safety outputs de-energize within the specified response time.
Fault Detection
If a fault occurs, the internal relay circuit forces the safety outputs off. One or both
output status indicators can be off. The PWR status indicator can flash. Remove
the fault and cycle the safety input to re-enable the device. Cycling power to the
safety relay can also clear the fault condition.
