EK12/fu : 03 11.ß~ The Simplatron controller series 490 comprises five 4—quadrant DC speed controllers with 6.4 to 80 kW output power in compact design. 1. Special features compact controllers with potential-free heatsink Highly dynamic due to six-pulse three-phase bridge design and discontinuous current adaptation Isolation due to current transformers —...
RKI2/fa cba~e4: 03.11.891 Installation instructions When installing in an enclosure, ensure adequate ventilation. The ambient temperature inust not exceed 45 0C. Install the controller vertically with the terminals at the top. Ensure that there is adequate ventilation. Observe power losses. See 12.3. When the switch RFR is closed, the controller is released.
— page: 5 When connecting, check for the clockwise rotating field. ~—.. In case of an anticlockwise rotating field the wrong phase sequence is displayed by lighting of the LED SEQ, the firing pulses are inhibited. Capacity of the +Vcc supply. For a supply of external option boards, a total output current of 5OmA is available.

After having checked and corrected the wiring, the commissioning can start again. When the speed is stable, the desired maximum speed can be set.

Caution: Ensure that the components mentioned above have suitable voltage values. Trimmer n 0ff5 The offset of the trimmer is factory set; however, if a correction should be required, zero can be adjusted at the trimmer for set value provision.
