Deleting the error/short circuit/overload
You can delete the error in one of the following ways:
S
Briefly interrupt the CP connection on the CP input
module
or
S
Briefly interrupt the operating voltage for the CP system
on the CPV Direct.
The inputs can then be interrogated again. If the short circuit/
overload still exists, the error will be shown again.
Module CP-E16-M8-Z:
The short circuit/overload will be reset automatically and the
