3.2 Emergency Stop Input and Output
An additional emergency stop push button can be connected to the system at the
"Emergency Stop" input (14).
If no additional emergency stop switch is connected, the socket must be terminated with a
jumper plug. (Scope of delivery)
The "Emergency Status" connector can be used to transfer status signals to other devices.
The Emergency Status plug connector a relay output of the status of the safety relay. If the
AC and DC outputs are enabled, the relay output (pin 1+2) is closed. If the emergency stop
function is triggered, the safety relay interrupts the relay contact.
If the outputs are not enabled via the Output ON/OFF switch, the relay output is permanently
open.
