The user program is processed in test mode. All monitoring functions are active in accordance
with the set parameterization. Logic outputs of function elements can be set (forced). This
makes it easier to carry out troubleshooting in the application and check the wiring.
Automatic system starting in the test mode
Can Cause Death, Serious Injury, or Property Damage.
In the test mode, the safety program is executed and the outputs are controlled according to
the safety program.
Take appropriate organizational measures, such as deactivating the main circuit or cordoning
off parts of the system, to ensure safety for persons and the system.
Safety mode (DEVICE LED: green)
In safety mode, all monitoring functions are active in accordance with the set parameterization.
Safety mode can only be exited by means of a command.
Startup/self-test
Once the power supply has been applied, the safety relay performs a self-test. During the self-
test phase, both LEDs on the safety relay light up for 2 seconds (lamp test). Two-color LEDs light
up yellow. The safety relay then loads the configuration from the memory and checks whether
a valid configuration or parameterization is stored and released and automatically switches to
safety mode (DEVICE LED lights up green).
The safety relay enters configuration mode (the DEVICE LED lights up yellow) when:
• No configuration exists,
• The TARGET configuration differs from the ACTUAL configuration (the SF LED lights up red)
• The existing configuration has not been released.
• The memory module (45 mm unit) is missing or defective: In this case, only the diagnostics
of the safety relay is possible (DEVICE LED flashes red, SF LED lights up red).
