DESCRIPTION OF OPERATION
The circuit supplies to the vibrator a control signal modulated in impulse width (PWM), which can be regulated both in Amplitude and Frequency. This signal will be compensated as to variations of the line voltage. The protections by fuses are as follows: F1 (6.3 A fast or 4A slow) on the input line, F3 (250 mA) on the ON/OFF input by limiting the current available on the NPN/PNP sensor and/or electro-valve air bolw, F2 (4A) on the vibrator output.
The green Led LD2, when On, shows the presence of voltage in the control circuit. It is light Off if are broken fuses F1 and/or F2 and/or F3.The red Led LD1, when On, shows the presence of voltage on the filter capacitors (till 300V with 230V line voltage). The circuit must never be touched when the red Led is On. The yellow Led LD3 when On shows the ON/OFF relay about ON/OFF vibrator (CONN4).
MODE OF USE AND ADJUSTMENTS

The entire control section is galvanically isolated from the power section. When on-switching the circuit. The voltage is supplied to the vibrator, the status relay switches over.
Therefore, the following steps can be carried out:

  • Set delay time at the start of the feeder with the TR3 trimmer (0/10 sec) or the delay at the stop of the feeder with the TR2 trimmer (0 / 10sec).
  • Block and restart the feeder with an external control from both a free contact voltage and a sensor NPN or PNP or from a 0 / 24V output by inserting or not the delays mentioned above (see detail Connector 3).
  • With DP1 you can select the straight or negated logic of the ON / OFF signal coming from the sensor or from contact connected to CONN3 (see CONN3 connections).
  •  Adjust the start ramp with TR5 (0/3 sec.).
  •  Adjust with TR4 max amplitude on the vibrator – adjustment with TR6 min Amp on the vibrator.
  •  Automatically adjust the amplitude with 0-10V (4-20 mA) signal by entering CONN7 – setting AUT with DP2.
  •  Select the adjustable frequency range with DP1: F1 = 50Hz +/- 12Hz (3000 vib per min. – 3600 vib per min.), F2 = 100Hz +/- 12Hz (6000 vib per min. – 7200 vib per min).
  •  Overload: electronic current limitation at 5 Amps.

      DESCRIPTION OF OPERATION
      The circuit supplies to the vibrator a control signal modulated in impulse width (PWM), which can be regulated both in Amplitude and Frequency. This signal will be compensated as to variations of the line voltage. The protections by fuses are as follows: F1 (6.3 A fast or 4A slow) on the input line, F3 (250 mA) on the ON/OFF input by limiting the current available on the NPN/PNP sensor and/or electro-valve air bolw, F2 (4A) on the vibrator output.
      The green Led LD2, when On, shows the presence of voltage in the control circuit. It is light Off if are broken fuses F1 and/or F2 and/or F3.The red Led LD1, when On, shows the presence of voltage on the filter capacitors (till 300V with 230V line voltage). The circuit must never be touched when the red Led is On. The yellow Led LD3 when On shows the ON/OFF relay about ON/OFF vibrator (CONN4).
      MODE OF USE AND ADJUSTMENTS
      The entire control section is galvanically isolated from the power section. When on-switching the circuit. The voltage is supplied to the vibrator, the status relay switches over.
      Therefore, the following steps can be carried out:
       Set delay time at the start of the feeder with the TR3 trimmer (0/10 sec) or the delay at the stop of the feeder with the TR2 trimmer (0 / 10sec).
       Block and restart the feeder with an external control from both a free contact voltage and a sensor NPN or PNP or from a 0 / 24V output by inserting or not the delays mentioned above (see detail Connector 3).
      With DP1 you can select the straight or negated logic of the ON / OFF signal coming from the sensor or from contact connected to CONN3 (see CONN3 connections).
       Adjust the start ramp with TR5 (0/3 sec.).
       Adjust with TR4 max amplitude on the vibrator – adjustment with TR6 min Amp on the vibrator.
       Automatically adjust the amplitude with 0-10V (4-20 mA) signal by entering CONN7 – setting AUT with DP2.
       Select the adjustable frequency range with DP1: F1 = 50Hz +/- 12Hz (3000 vib per min. – 3600 vib per min.), F2 = 100Hz +/- 12Hz (6000 vib per min. – 7200 vib per min).
       Overload: electronic current limitation at 5 Amps.
