Input n level
You use this device parameter to specify the input logic:
● Normally closed contact
● Normally open contact
Note
If you specify "Input n action": "Emergency start", "Motor CW", "Motor CCW", and "Trip
reset", you can only program "Input n level" as an NO contact.
Note
If "Input n level" is changed from an NC contact to an NO contact and the associated
"Input n action" is parameterized as "Trip without restart", the "Input tripping" message bit
is set and tripped accordingly in the event of an open input, as a result of the input delay.
Note
If an input voltage is applied (input active), a 1 is transferred to the controller regardless
of the "Input n level"; please refer to the figure titled "Overview of input parameters".
Input n action
Different actions can be triggered when an input signal is present. You can parameterize the
following actions depending on "Input n level", "Input n signal", and "Mode".
Note
If "Input n signal" = retentive and "Input n action" = motor CW/CCW, at least one input must
be parameterized with input action "Tripping ... " or "Quick stop" at all times.
If this rule is not followed, the motor starter will reject the parameters and issue the relevant
diagnostics message.
