External fault message (EXT)
When the digital input configured as EXT is activated, fault
message E12 is issued (for example to be used as input for
thermistor contacts). The fault message remains active even if the
EXT input is deactivated again and must be acknowledged with a
reset.
A reset can be carried out with:
• the RST input or
• the OFF key.
• Alternatively, the supply voltage can be switched off and on
again.
X
Program one of the digital inputs 1 to 5 as EXT by entering the
value 12 under the corresponding PNU (C001 to C005).
