Functional description
The KLIBO-Star-Delta-Brake-Timer system has been developed with star-delta starting and braking of cage motors in mind. Starting and braking times are adjustable and can be set to meet specific application requirements. All other operating sequences are time optimized and are controlled and monitored by a controller with watch-dog feature. Powerful relays actuate the output signals for star, delta, and braking contactors. The additional integrated relay allows to interlock the control circuit and - if necessary - the main switch during braking. The KLIBO-Diode-Brake and KLIBO-Phase-Brake systems are particularly well suited for braking applications. These models use a braking contactor to switch the braking current to the motor coil. For maximum braking torque, the braking current can be wired to 2 or 3 coils. With the 2 coil braking system, a jumper can be used to activate the star contactor during braking.
