3.0 Applications
Star-delta start-up, examples
Category B, EN 954-1
Features
1 reset module
2 logic connections
3 semiconductor outputs
1 instantaneous load shutdown
2 load shutdowns with a 5 s delay
Description
When the motor is switched on, after a
5 second delay it is possible to switch
between a star and a delta connection.
A high signal at input A1.i4 selects a
star connection, a high signal at input
A1.i5 selects a delta connection.
Feedback loop
The feedback loop is not used.
Reset
The PNOZ m1p is ready for operation
once supply voltage is applied. If there
is a high signal at input A1.i0, the application
can be activated through a
signal change from low to high at input
A1.i1.
