12.5 Binary Outputs
With respect to binary outputs, the integrated self-monitoring function includes
even two-phase triggering of the relay coils of all the relays. There is no
monitoring function for the external contact circuit. In this case, the all-or-nothing
relays must be triggered by way of device functions or integrated test functions.
For these testing purposes, triggering of the output circuits is integrated into the
software through a special control function (Oper/CtrlTest menu branch).
Warning!
⚫
Before starting the test, open any triggering circuits for external devices so
that no inadvertent switching operations will take place.
