A trip can only occur while the soft starter is
running.
Function:
activating and soft starter tripping.
Function:
Sets a delay before an input trip can occur.
The initial delay is counted from the time a
start signal is received. The state of the input
is ignored until the initial delay has elapsed.
Function:
Selects whether the remote reset input of the
soft starter (terminals 25, 18) is normally
open or normally closed.
Function:
Selects the function of relay A (normally open).
Relay A is not used
The relay closes when the soft starter receives
a start command and remains closed as long
as the motor receives voltage.
The relay closes when the starter changes to
run state.
The relay closes when the starter trips.
The relay closes when the starter issues a
warning.
The relay closes when the low current flag
activates (parameter 4-10 Low Current Flag).
The relay closes when the high current flag
activates (parameter 4-11 High Current Flag).

8.4.2 Relays B and C

Parameters 4-4 to 4-9 configure the operation of relays B
and C in the same way as parameters 4-1 to 4-3 configure
relay A. See parameter 4-2 Relay A On Delay and parameter
4-3 Relay A Off Delay for details.
•
Relay B is a changeover relay.

Function:
The relay closes when the motor temperature
flag activates (parameter 4-12 Motor
Temperature Flag).
Function:
Sets the delay for closing relay A.
Function:
Sets the delay for reopening relay A.
Function:
Selects the function of relay B (changeover).
Relay B is not used.
The relay closes when the soft starter receives a
start command and remains closed as long as
the motor is receiving voltage.
The relay closes when the soft starter changes
