Christian P-4.0/RL/TP/IC by Tele Haase

Description

The smart motorstarter function is a softstart, reversal and protection of 3-phase asynchronous motors. Overcurrent is detected when the set current is exceeded longer than 2 sec. Direction reversal takes place via relay switching. The relays are de-energised at this. This ensures a long service life.

Functions

• Soft starter

• Up to 6 functions in one unit
  • Reversing anticlockwise
  • Reversing clockwise
  • Softstart
  • Softstop
  • Current monitoring or motor protection (optional)
  • Galvanic separation via forcibly guided contacts with contact distance min. 0.5 mm (optional)
• 80 % less space
• Simple and time-saving commissioning as well as user-friendly operation through setting via potentiometers on absolute scales
• Blocking protection
• Hybrid relay combines benefits of relay technology with non-wearing semiconductor technology
• High availablility by
  • Temperature monitoring of semiconductors
  • High withstand voltage up to 1500 V
  • Load free relay reversing function

• Reversing operation for door and gate controls, bridge drives and lifting applications with monitoring of blockage
• Conveyor systems with monitoring of blockage
• Actuating drives in process controls with blockage monitoring

• The thermal load of the motor is calculated using a thermal model
• The nominal motor current can be adjusted via potentiometer Ie
• To calculate the thermal load the current is measured in phase T3
• A symmetric current load of all 3 phases of the motor is assumed for flawless functioning
• When the trigger value – stored in the trigger characteristics -, is reached, the motor is switched off and the device switches to fault 8
• The fault can be acknowledged via the reset button or reset input
• Attention: The data of the thermal model is cleared through reset or voltage failure. In this case, the user must provide adequate cooling time of the motor

• In off state or fault condition the motor terminals are isolated from the mains voltage by a 4 pole forcibly guided contact relay
• The contact opening is min. 0.5 mm.
