CHAPTER 2: FUNCTIONAL SAFETY
NOTE! The information in this section applies only to the products specified below.
SAFETY FUNCTION
The safety-related stop function in the radio system complies with EN 13849-1:2008 Category 3 PLd.
The stop relays on the receiver unit are controlled by the stop button on the transmitter unit. When the
stop button is pressed, the stop relays interrupt the power to the safety-related application. The
complete end-user system, including the radio system, enters a safe state. The maximum response time
for the safety-related stop function is 500ms.

ELIGIBLE PRODUCTS
The following transmitter and receiver units are designed to comply with the appointed safety
requirements:
Receivers: PN-R15-1, PN-R15-2, PN-R15-13, PN-R15-14
Transmitter: PN-T19-2
NOTE! Both the receiver and the transmitter used in the specific end-user system must be compliant.
INSTALLATION
The stop relays on the receiver unit must be correctly installed on the end-user system, to ensure that
opened/deactivated stop relays interrupt the power to the safety-related application. The safety level of
the stop function can only be credited when used in a complete end-user system that complies with EN
13849-1:2008 Category 3 PLd.
When used in a machine control system, the Panther stop function must be supplemented by a feature
requiring a deliberate action by the operator to restart the system after an external power supply failure.
CONFIGURATION
The default configuration of the receiver unit complies with the appointed safety requirements. Any
reconfiguration that breaches the safety requirements will be indicated by a LED on the main board of
the receiver unit. Before commissioning the radio system, the installer must check the LED indication.
