  • Page 14: Voltage Change

    4.8. Voltage change The ESR2500/2800 can be operated with various supply voltages and magnet voltages. For changing the voltage you must open the controller. Therefore, be sure to observe the safety instructions and general warning notices in Chapter 2. You can set the controller to a mains supply voltage of 230V or 115V. If set to a mains supply voltage of 230V the magnet voltage is always 200V.

  • Page 15: Operator Panel And Display Of The Controller

    5. Operator panel and display of the controller 5.1. Operator panel - Display The operator panel of the ESR2500/2800 controller comprises four buttons and a 2x16 digit display. Speed 100 % A Stopped The functions assigned to the buttons are as follows: ON / OFF is used to switch the connected feeder on and off.

  • Page 16: Navigating Through The Menus

    5.2. Navigating through the menus There is 1 main menu and 2 submenus for operating the ESR2500/2800 controller. From the main menu you can en- ter the set-up menu or the calibration menu by entering the required password. Use the arrow buttons for navigation through the menu screens. The menus are circular so that navigation beyond the last screen of a menu will take you back to the first screen and vice versa.

  • Page 17: The "Info" Screen

    The set speed determines the vibration amplitude. The controller operating mode is indicated to the right of the speed percentage by M for manual mode or A for auto- matic mode. In Manual mode the speed is indicated in percent of the maximum output voltage. When the controller is calibrated and you switch the mode to Auto the speed is shown as a percentage of the maximum calibrated speed.

    6.1.1. Accumulation checker (sensor inputs) You can connect up to two sensors to "sensor connection" XS2 for accumulation monitoring or level monitoring. See connection diagram in chapter 4.6 and 4.7. The signal may, e.g., come from a light barrier indicating whether an accu- mulation section is full or not.

    6.1.3. Display calibration You can configure the display on the controller as required. In the Display Calibration menu item you can set the contrast/brightness. When lighting is set at "Normal" pressing of a button illuminates the display and after 10 seconds the light extinguishes again. When lighting is set to "On" the light remains on and if set to "Off"...

    6.1.5. Analogue speed input Speed setting (0-100%) can be controlled from an analogue source that can be set at 0-10V, 0-5V or 4-20mA. The connection is of the clamping type and located at the right-hand side in the controller, see chapter 4.7 and 4.8. Parameter description Output parameter Range...

  • Page 22: Active Braking

    6.1.8. Active braking The active brake prevents a feeder vibration stop delay once the feeder is stopped. This option is particularly useful where counters are involved. Once the feeder has been stopped, feeding of further parts is to be avoided to the extent possible.

  • Page 23: Fine Tuning

    7.1.2. Fine tuning Fine tuning of the minimum and maximum speeds is mandatory after successful calibration. Take great care in fine tuning because otherwise the controller cannot operate the vibratory drive in the proper way, see chapter 7.2. After the speeds you can also adjust damping, if required. The speed and damping values can also be adjusted later on without the need for re-calibration.

  • Page 24: Calibration Process

    7.2. Calibration process In order that the controller works perfectly with the vibratory feeder connected, it must be calibrated to suit the feeder. After calibration, the determined calibration parameters are saved and re-loaded automatically every time the control- ler is started. Before calibration, set the correct current range;...

  • Page 26 Fine tuning of minimum speed Here you set the minimum speed at which the feeder is to run. Place some parts into the bowl, start the feeder using the ON/OFF button and set the minimum speed using the arrow buttons. The parts in the bowl must move slowly. It is particularly important to make sure that the feeder runs smoothly for at least 10 seconds.
  • Page 27 Set damping Here you can set damping of vibration amplitude control. If the feeder overshoots on starting or if speed setpoint changes cause vibration amplitude fluctuations it is advisible to set the value a little higher.If such cases do not hap- pen with your feeder but it responds slowly to load changes we would recommend to set the value a little lower.

  • Page 28: Memory Reset

    8. Memory Reset Attention This resets all parameters to the default values! Resetting to default values In order to reset the controller to the factory settings open the power switch to disconnect the supply voltage and wait for the display to darken. Now press and hold down the two "up" and "down" arrow buttons and then switch-on supply voltage again.

  • Page 30: Overload Protection Active

    10.1.2. Overload protection active This alarm comes up if the load current exceeds twice the value of the maximum r.m.s. current. In this case the con- troller disconnects the output voltage immediately to protect the output stage against overload. The alarm message remains on the display until it is reset by Enter.

  • Page 31: Vibration Restricted

    10.1.5. Vibration restricted This alarm appears if the controller cannot maintain the required speed (vibration amplitude) without overloading the oscillating magnets. This alarm message appears if the feeder speed is less than half the set speed but the feeder draws the full current. This is not necessarily a malfunction;...
