6 General Information Nameplates The machine is identified by two plates: one on the motor, with its nominal data, and the second one on the machine with the CE mark. The serial number is very important: you have too mention it for every request for spare parts, information and service. Machine description Overview The single head machine 40K/2 Mv DPHAA is engineered for manual operations of polishing and buffing of metal items. The machine is engineered to be used by only one operator This machine can use only polishing and buffingg wheels, and not tools such as grinding stones orr cutting discs. The use of this tools is severely forbidden,, and very dangerous forr the operator. The machine is made by: the motor, the pedestal complete of height adjustment system, the belt arm, the electric equipment, the lamps and the t control panel. Machine specifications model 40K/2 Mv DPHA Power supply 3 Phase + ground + neutral, 400V 50Hz Motor rating [kw] 3 Speed [rpm] Variable from 3003 to 3000 Protection classification IP 544 Insulation class F Table 1 Safety devices The machine is equipped with safety devices needed to ensure the safety of the operator. Thesee devices must not be removed or deactivated for any reason o o o o o ELECTRIC EQUIPMENT: in compliance with the norm UNI EN WHEEL PROTECTION GUARD: it covers the buffing wheels and convey the dust producedd during the working process. EMERGENCY STOP: there are three e stop: one on the control panel, one onn the motor, plus the foot pedal. MOTOR BRAKE: it is able to stop the spindle in a few seconds. When the motor is not powered, the brake is engaged and the motor shaft iss locked. DOOR INTERLOCK: when the wheel guard is open, the machine cannot run; also when the machine is running, the door guard can t c be open. 6

7 o ELECTRIC CABINET: the cabinet can be opened only when the main switch iss OFF IMPORTANTT The wheel guard must never be removed: it must always cover the rotating parts and ensure the bestt possible dust catching.. 7

8 Machine installation Lifting Warning: it s not allowed to lift the machine using ropes below the motor. This couldd cause major damages to the height adjustment system. To move the machine, it s necessary to use a forklift, rising it from the base of the pedestal. The machine is shipped fixed on two wooden blocks, to allow an easier lifting slidingg the forks below the pedestal. Keep the machine balanced while moving. 40K/2 Mv DPHA weight: 500 Kg Installation The machine must be fixed to the floor using 4 bolts through the holes in the pedestal. Consider at least a space of 1 meterr from every side of the machine. Lights installationn Install the lamps as shown in the picture below. The height of the lamps can be adjusted, using the holes in the frames. Be careful while moving the frames! The cable must pass inside the frames, and connected into the electric cabinet c as per the schematics at the end of the manual. Please note that there s a guidance copper wiree inserted into the tubular frame of the machine. Use it to drive the lamp wire out of the frame and into the electric cabinet. Pic. 3 Connection to the dust exhauster The machine must be connected to a dust exhauster. The wheel guard have h got an extraction pipe ø150 mm. Use an adequate flexible pipe. We suggest a capacity of at least 750 mc/h for the dust exhauster. Electrical connections Check the voltage and the frequency values on the machine plate (3 phase + groundd + neutral, 400V 50Hz). Connect the power wires to the terminals into the electricall cabinet (ref. electrical drawings at the t end of this manual). 8

9 Operator safety This machine can be dangerous if used under improper circumstances. Read R the following notess and observe them during the work. o o o o o o o o Keep the machine and the work area neat, clean and orderly. Keep all the machine guardss in place. Do not touch rotating parts. Ensure you know how to stop the machine before starting it. Do not operate the machine in excess of its rated capacity. Do not wear rings, watches,, ties or loose sleeved clothing. Wear adequatee safety protections equipment (glasses, gloves ) ) Stop the machine immediately anythingg unexpected happens. The operator must stand in front of the buffing wheel. He must be able to reach easily the e stop foot pedal and the control panel. 9

10 Use and maintenancee Running-in and lubrication This buffing machine needs a short period of running in. Don t overload the spindless during the first hours of work. No lubrication is neededd for the machine. Tools The machine can use the following buffing wheels: Buffing wheels: ø14 x2 MAX mm, bore 30 mm. The machine is supplied with 3 adapters ø180/30 mm for the buffing wheels, and two external aluminum flanges to lock the wheels. Refer to the next paragraph for the installation. 10

11 Wheels installation Follow this procedure to install the buffing wheel: Turn off the machine. With the brake not engaged, manually rotate the shaft until it s possible to insert a pin to t keep it locked. There s an hole into the shaft guard to be used as pin entrance. Press the e stop button to engage the brake. The reset blue button will turnn off. The interlock will be released after 10 seconds. Open the wheel guard. Install the buffing wheels ass in the drawing below: insert the adapters in every mop, and close them with the external flanges. Keeping the shaft locked, tighten the locking nut on the shaft. Remove the pin from the shaft. Close the wheel guard, release the brake pressing the reset button, and turnn the wheel manually: make sure there re no interferences with the guard. WARNING: before starting the motor, always be sure that the shaft can rotate freely and the locking l pin has been removed. Pic. 4 Pic. 5 11

12 Control panel Lamps 0 1 switch: it turns on/off the machine lamps. Power (white light): it lights when the t main switch is ON Display: it shows the speed of the spindle (rotation per minute) Emergency stop: it engages the brake and resett the machine Red Height adjustment mode off: it disable the height adjustment mode. Orange Height adjustment mode on: it enablee the possibility of changing the centerline height. While this mode is active (orange light and buzzer on), thee motor can t start. Black Arrow up: it increases the speed of the motor. Black Arrow down: it decreases the speed of the motor. Blue Reset: engages the safety circuit. When it s light, the interlock is locked and the brake is released. The operator is allowed to adjust the height, or start the motor. Red Stop: it stops the motor (spindle). The deceleration is assisted by the t motor drive. Green Start: it starts the motor (spindle), reaching the speed shown onn the display, according to t the acceleration ramp set in the motor drive.

14 Height adjustment The machine is equipped with a guided lifting electric column, able to change the centerline height from 1000 to 1200 mm. This is the procedure to change the height of the machine: Be sure that the main isolator switch is on Press the blue reset button (its light must be on) Enable the height adjustment mode pressing the orange button: an intermittent beep will start to remember that the machine is in height adjustment mode It s now possible to lift or drop the machine using the remote control as explained in the next chapter When done exit from the height adjustment mode pressing the red button. RK remote control The remotee control is positioned on the left sidee of the machine. Ref. Pic. 7 A display. It shows the height of the bench from the floor in millimeters. It can change from 1000 to F button: advanced options (user and memories). 2 down arrow: decrease the height of the machine. 3 up arrow: increase the height off the machine. 4 memory keys. Manual position traversing Press the DOWN or UP key and maintain depressed until the requested height is reached. Saving and moving to positions Alongside manual traversing of the drives using the UP and DOWN keys it is also possible to save positions and thenn move automatically to the saved positions. As many as 3 users can each save up to 3 positions, i. e. a total of 9 positions can c be saved. We highly recommend that you always use position saving if the drives are constantly to be moved to repeating positions by different users. Pic. 7 Two steps are needed to save a position. The first step requires the userr to assign a user level. The position is stored by a specific memory button in the second step. Specify a user Example: You wish to save your positions as user 1. Repeatedly press the F key until the last selected user (e. g. USE.3 ) appears in the display. Press memory key I within 5 seconds. USE.1 will now be displayed. You have now selected user 1. Now you can save a position using a memory key as user 1. Saving a position under a memory key Example: You wish to save position 1050 in user level 1 under memoryy key 2. Press the UP or DOWN keyss until 1050 is displayed. Repeatedly press the F key until POS. is displayed. Press memory key II within 5 seconds. You have now saved the position underr memory key 2. You can now move to the position by keeping memory key II depressed. 14

15 Moving to a stored position Example: You wish to move to the 1050 savedd position using a memory key. The position has already been saved in user level 1 under memory key 2: 2 Repeatedly press the F key until the lastt selected user level (e. g. g USE.2 ) appears in the display. Press memory key I within 5 seconds. USE.1 will now be displayed. The correct user level has been selected. Press memory key II and keep depressed until the drives have been moved to the saved position. WARNING Ensure thatt nobody is near the machine when changing the height. Therefore, onlyy use the manual control switch if you can see the entire machine risk of accidents! 15

16 Electromagnetic disc braking The main motor is equipped with an electromagnetic brake, This brake is engineered to ensure, at rest, the intrinsic safety. When the electromagnet (1) is excited, the armature plate (2) is attracted to the electromagnet thanks to the springs (3). In this way he disc (4), coupled with the shaft thanks to the t splined hub, can rotate freely. When there s no tension, the springs pull the armature plate against thee disc, braking the shaft. Braking torque setting The K7 brake that equips the motorr of the machine can be adjusted accordingg to the braking torque, the load, the speed and the braking time. It s possible to adjust the braking changingg the distance between the electromagnet and the adjusterr ring. Adjust the braking torque according to the following table, which showss the brakingg torque in relation to the distance from the electromagnet to the adjuster ring. DISTANCE BETWEEN ELECTROMAGNET AND ADJUSTER RING [mm] BRAKING TORQUE [Nm] Table 2 According to Pic. 8, follow these instructions: o Switch off the machine o Gain access to the brake room o Rotate the adjuster ring to change c the distance Pic. 8 16

17 Maintenance Weekly Clean the dust accumulated in the wheel guard.. Check if all the emergency stops works correctly. Monthly Check the bolts of the wheel guard are correctlyy locked. Check if the height adjustment system is working. Yearly Run the motor without the buffing wheels, and check for any bad bearing noise. 17
