Safety-Related F 3430 Relay Module
Relay output modules are connected to the actuator under any of the following circumstances:
l Electric and galvanic separation is required.
l Higher amperages are to be connected.
l Alternating currents are to be connected.
▏Test Routines
The modules are tested automatically during operation. The main test functions are:
l Reading the output signals back from the diverse, 3-channel relay switch.
l Checking the integrated redundant safety shutdown.
l Applying the test patterns and testing for crosstalk (walking bit test) during the background test.
▏Behavior in the Event of External
Short-Circuit External short-circuits cause the fuse for the relevant channel to trigger. No error message is issued.
▏Redundancy of Relay Outputs
Relay inputs may be wired redundantly. The redundant connection is used to increase the availability of the outputs.
HIQuad X output modules
The safety-related output modules write the values created by the user program to the outputs once per cycle. The output signals are read back and compared with the specified output data.
Additionally, all outputs for which the switched-on channels are briefly switched off and switched-off channels are briefly switched on are subject to background tests. The test pulses are present in the F 3330, F 3333, F 3335 and F3430 for 250 µs.
These tests ensure that the switchability of the outputs is checked without affecting the function of the connected actuators, if these tolerate the test duration of 250 µs. As a result, the freezing (switch welding) of each output is detected, even if the output signal is static.
If inductors or lamp loads are connected, the test pulse duration configured for output modules with line monitoring must be checked and, if necessary, extended. The safe state of the outputs is 0 or an open relay contact. To ensure the module's proper operation, HIMA cable plugs must be used.
