Connecting Outputs In Parallel; Transistor Output Behavior In The Event Of A Short Circuit/Overload57 - Eaton easyE4 series Manual

2.4.6.1 Transistor output behavior in the event of a short circuit/overload

2.4.6.2 Connecting outputs in parallel

The following applies to easyE4 devices with transistor outputs:
In the event of a short circuit or overload at a transistor output, this output will switch
off and a general fault alarm ID (please refer to fault IDs) will be set to 1. The output will
switch back on up to the maximum temperature after a cooling time that depends on
the ambient temperature and the current level. If the fault continues, the output will
switch off and on until the fault is rectified or the power supply is switched off.
Only outputs of the same group (Q1 to Q4 or Q5 to Q8) can be connected in parallel; e.g.
Q1 and Q3 or Q5, Q7 and Q8. Parallel switched outputs must be similtaneously ener-
gized.
DANGER
If the outputs are not switched on and off automatically, or if outputs
from both groups are connected in parallel, this may result in mal-
functions such as short circuits or the load not switching on
