External fault message EXT
If the digital input configured as EXT is activated, the fault
message E12 is initiated (e.g. an input used for the bimetal
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 inputting the
value 12 under the respective PNU (C01 to C05).
