3 1. Safety instructions for users These instructions contain the necessary information for the correct use of the products described. They are for use by technically qualified persons. Qualified personnel are those persons whose vocational training, experience and internal training and their knowledge of the relevant standards, regulations, accident prevention regulations and plant operating conditions has led the person responsible for operational safety to authorise them to carry out the necessary work, and are able to recognise and avoid potential risks (definition of skilled workers as per IEC 364). Risk information The following information serves not only the personal safety of the operating personnel but also the safety of the products described herein and appliances connected to them. DANGER! Highvoltage operations. Noncompliance can lead to death, serious injury or damage to property. Always disconnect the supply voltage before assembly or dismantling work, when replacing fuses or altering the structure. The relevant Accident Prevention and Safety at Work Regulations must be complied with at all times. Before commissioning, make sure that the appliance's nominal voltage conforms to the local mains voltage. EMERGENCY SWITCHES must remain operational in all working modes. Unlocking EMERGENCY SWITCHES must not lead to uncontrolled. Electrical connections must be covered at all times! After assembly, check all protective conductor systems for correct functioning! Proper use The appliance described here is an electrical device for use in feeder equipment or automation plant. The appliance has been planned for use in oscillation conveyors, in control and automation technology. 3

4 This appliance conforms to the relevant LowVoltage and EMC Guidelines. 2. Application The SMS 150/151 electronic controller is used for stepless control of inductive loads such as spiral conveyors, linear conveyors and hoppers. The controller works on the phase control system, the conveyor output is carried out by setting the magnet voltage via the setpoint potentiometer integrated in the casing cover. The control curve of the setpoint value voltage can be restricted by means of two trimming potentiometers, Umin and Umax, on the board in such a way that the complete range of the setpoint value can always be used. The ignition impulses can be displaced infinitely in the range of the positive or negative mains voltage halfwave through the setpoint voltage adjustable with the setpoint, which then sets the voltagetime area of the output voltage is set. With feeder appliances with 50 Hz oscillation frequency both (positive and negative) mains voltage halfwaves are controlled, and with feeders with 25 Hz oscillation frequency only one mains voltage halfwave is controlled. The switchover between fullwave and halfwave mode is carried out as a standard with a sliding switch on the board (see Connection Possibilities). After the working voltage has been switched on the integrated variable softstart is started and guarantees smooth acceleration of the output voltage to the preset voltage value. This eliminates possible switching peaks. In addition, the softstart, and the softstop, become effective when the output voltage is switched on and off via the controller input for the level control system and serves to increase or decrease the conveyor output on a timecontrolled basis so that bulk material does not change its position. Both these times can be set separately. The controller input controls the running time of the oscillation conveyor in such a way that unnecessary running time are avoided. Internal variable times (GAN and GAB) are used to turn the oscillation conveyor ON or OFF in dependency on the material level measured via a material sensor. The controller input enables the turn On and OFF of the controller load output through another system (SPS, initiator, sensor and other). The controller has an integrated power supply for +24VDC. A turn ON and OFF through a external +24VDC voltage is possible. The controller input takes affect to the ignition pulses. Measurements of the output voltage (arithmetic value measurements) enable changes to the voltage to be registered immediately an compensated by means of a controller stage. This guarantees even running of the bulk material. 4

5 Miniature magnets can also be operated safely at the controller! Setting the ON and OFF time delay for the level controller The level of the material in the filling section is measured by the GAN and GAB trimmers. To increase the material backup downstream from the sensor, use the GAB trimmer to lengthen the controller's OFF delay time. Reduce the GAB time to reduce the backup of material. The GAN trimmer can now be used to determine the time that passes from when the last part of the material leaves the sensor position until the feeder appliance is switched on The diagram shows the time sequence in operations with the controller input low active: V GAN SA GAB SS X 0 0,110s 0,55s 0,110s 0,15s Output voltage t 1 0 Signal at control input t 3. Warnings!!! In the case of applications that require the oscillation conveyor to be switched ON and OFF constantly (e.g. dust switched off, hopper control system, etc.), the prescribed controller input must be used. If the load circuit is disconnected with a switch or a relay the controller may be damaged. If the controller is switched on, never insert or remove the plug at the vibration conveyor being operated. This can damage the appliance. Repair work must be carried out by qualified personnel only. We recommend that repairs are carried out on our premises. 4. Installation 5

6 For mounting of the controller there is a hole and a long hole accessibly from the outside. These holes are separated from the interior of the housing. Mounting on a vibration free background. Please notice, the interior ribbon cables may not squeezed against the housing. When the ribbon cables are squeezed there can be a shortcircuit and the controller can be destroyed! 6

11 4.4 Starting 1. Before connecting the controller, check the working voltage and working frequency of the conveyor and compare them with the technical data for the controller. The output current of 6A should not be exceeded. 2. Depending on the working frequency of the conveyor, set the slide switch on the board: Fullwave operations 50/60 Hz (slide switch above) Halfwave operations 25/30 Hz (slide switch below) Check the programming on the board in dependence on the type of switching and set. Connect the conveyor to the controller. Insert the controller's plug into the mains. Switch the controller on. Set the required control range with the Umin and Umax potentiometers. 5. Operating tips Before switching on, check that the controller is correctly plugged into the conveyor. Switch the controller on with a mains switch. If required, adjust the setpoint until the vibration conveyor reaches the desired output. 6. Repairs Replacing fuse 1. Replace defective fuse with a 6,3 A F fuse. Fuse is available over fuseholder in the cover. 11

12 7. Troubleshooting Appliance not working Check the mains voltage, check the fuse and replace if necessary. Is the controller input set correctly, programming correct? No output from conveyor Check whether the correct oscillation frequency has been set, change setting where necessary. Check the mains frequency (50/60 Hz). The oscillation frequency and the mains voltage must agree. Umax trimmer set too low. Set Umax. Conveyor vibrates too much, magnet knocking (noises) Oscillation frequency setting incorrect. CAUTION! Magnet may have been destroyed by overheating or damaged mechanically by knocking. Umax trimmer set too high. Set Umax if necessary. Magnet heats up Magnet has incorrect mains voltage, check. Incorrect oscillation frequency set, change if necessary. Controller input not working Control voltage polarity reversal, check. Correct jumper for controller input? Check. 12
