3.12
Level Ext. 1 Determination of the state
that activates an external
failure 1 (par. 3.10) 0 - low state of selected digital input
in parameter 3.10 activates
external failure 1
1 - high state of selected digital input
in parameter 3.10 activates fault
external 1
The parameter is available from software version
12.63.
1 YES
3.13
Level Ext. 2 Determination of the state
that activates an external
failure 2 (par. 3.11) 0 - low state of selected digital input
in parameter 3.11 activates
external failure 2
1 - high state of selected digital input
in parameter 3.11 activates fault
external 2
The parameter is available from software version
12.63.
1 YES
