Fault Description
number
Fault short circuit/overload

Short circuit/overload at an
output
The reaction depends on the para

off" (default):
The output is switched off
Only CPX−8DA:
Setting V
The output current is limited to
approx. 250 mA
Only CPX−8DA−H:

Fault treatment
1. Check actuators, eliminate short circuit/over
load (number of faulty channel: see LED display
or module diagnostic data).
2. Depending on the parameterization Behaviour
after short circuit/overload at outputs (SCO)":
Set output to 0, then set to 1 again or modify
·
parameter Behaviour after short circuit/
overload at outputs (SCO)" to V
again".
If the output current is lower than 400 mA:
·
The voltage will be switched on again auto
matically when the short circuit is eliminated.
If the output current is greater than 400 mA:
·
Set output to 0, then set to 1 again.
If the output current is lower than 2.1 mA:
·
The voltage will be switched on again auto
matically when the short circuit is eliminated.
If the output current is greater than 2.5 A, the
·
output begins to pulse. The frequency and
duration of the pulsing depend on tempera
ture and overloading/current value
(see Technical specifications" section A.4)
Check the load voltage

see Technical specifications" in the appendix.
