ASB20: Description of connections and function
Connection:
Control circuit:
Connector Description
SE Motor connection for stand-still detection
SP Control signal for brake
NC Control output for special functions
COM Release relay COM (base point)
NO Control release
Load circle:
Connector
Description
V Motor connection (see circuit diagram)
I Mains supply
N for 230 V
L2 for 400 V
L Input supply phase L3
C Motor connection (see circuit diagram)
When connection it is essential to connect the release relay COM and NO in the control circuit of the
motor contactor!
The brake should not be used on a transformer. If the brake is used in conjunction with our soft starter,
it is essential to ensure the order of connections.
LED-display:
Dis
play
Description
Red LED glows at that for short time Normal operation display
Green LED glows Stand-still or actuated motor
Normal operating mode
Green LED flashes Motor brakes
Red LED glows Error indication through:
- Excessed braking time
- Disrupted power supply
- See failures

Failures and corrective:
If a fault occurs, the red LED lights up permanently and a new start is not possible.
Fix the lock, by disconnecting the power supply for about 2 seconds.
The cause of the disorder may be due to:
Failures and
cause
Corrective
The braking time is higher than 14
seconds Improve the braking power so far that the engine stops under 10 seconds
The braking time is between 10 and 14
seconds. Here, the disturbance takes
place after the third braking
Improve the braking power so far that the engine stops
under 10 seconds
The motor cannot start (without error)
- Brake or mains circuit wrong connected
Please check wiring
- Brake defect
Send back device
- Mains supply incorrect
Check mains supply (fuse and so on)
Disorder occurs immediately when
switched on - Brake circuit (C or V) wrong connected
Check wiring
- Brake defect
Send back device
The engine starts, but then it don't
brakes. Unit indicates fault - Connection for stand-still detection is wrong (SE or C)
Check wiring
- Brake defect
Send back device
Trouble for no apparent reason - red
LED glows - The cause could be due to a short performance from the network fault
Error message by interrupting the power supply reset of
about 2 seconds. Possibly. caused the disorder to
another device on the same circuit.
