Behaviour in the event of a short-circuit/overload
In the event of a short-circuit or overload on a transistor
output of a easySafety basic device, all outputs are
disconnected. Once you have rectified the fault or
malfunction, you can reset the easySafety device by
switching the power supply off and on again.
If the short circuit or overload occurs on a non-safety
expansion device, only this output switches off. 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 condition persists, the output
will keep switching off and on until the fault is corrected or
until the power supply is switched off (
a section
“Diagnostics”, page 615).
Special requirement for ES4P-221-DMX.. devices with
device version 02 or 10
It is necessary to ensure that, in the event of a short-circuit,
the power supply unit being used will provide sufficient
current to reliably trip the selected F2 cable protection. This
is only required for applications that use two-channel safety
modules (redundant outputs).

Danger!
Danger! Only outputs of the same group (S1 to S4 or S5 to
S8) can be connected in parallel; e.g. S1 and S3 or S5, S7
and S8. Outputs connected in parallel must be switched at
the same time.
