4 Rev. 03 Con-Evator Page GENERAL INFORMATION 2.1 Application The Con-Evator SVR is a vacuum hopper loader designed for conveying of free-flowing granular plastic material from a bag or bin to the intermediate hopper of the processing machine or another hopper. 2.2 Restrictions The SVR unit may only be used for the purposes specified. The SVR unit can be used neither for powders (only in special version) or liquids, nor for living creatures. The SVR unit must be used by a qualified operator only, following the correct procedures. The blower with motor and control must not be used in a potentially explosive atmosphere. The hopper may only be used in such atmosphere if the bottom flap has been fitted with an explosionproof power switch. The power switch will be marked with an explosion-proof label. IMPORTANT! The person in charge of the placing/operation and or owner is responsible for the prescribed and adequate installations, corresponding to the local regulations. In other words, only authorized or trained personnel is allowed to install the equipment. Should the equipment be interfered with by unauthorized or untrained personnel leading to damage, or should the consumer allow the equipment to be interfered with in this manner by third parties, then all claims under guarantee relating to the entirety of the object concerned become null and void. The right to carry out changes in design is reserved, without however incurring the obligation to effect such changes, even in equipment already supplied. This information is based on our present state of knowledge and is intended to provide general notes on our products and their uses. It should not therefore be construed as guaranteeing specific properties of the products described or their suitability for particular applications.

6 Rev. 03 Con-Evator Page Operating principles Conveying (drawing R2369) 1. By means of the blower (7), a vacuum is generated inside the hopper loader (83); the blower is driven by an electric motor (6). This causes the bottom flap (13) to close against the outlet of the hopper resulting in a vacuum in both the conveying hose (2) and the suction probe (14). Ambient air is consequently sucked in through the outer pipe of the suction probe, carrying material with it to the hopper through the suction pipe (14). 2. BLOWER ON time (the time the blower is required to generate a vacuum) is set at the control. 3. During conveying the conveying hose (2) may be cleared. A line clearing valve located right above the suction probe opens in a preset time integrated in the conveying time. Air is admitted into the system, now via the suction hose instead of the suction probe, and thereby clearing of the hose is effected. See section 5.0 Accessories. R When the blower is turned off the weight of the material sucked into the hopper loader will cause the bottom flap (13) to be pressed down and the material to fall into the intermediate hopper (5). 5. If there is sufficient room in the intermediate hopper for all the material, the bottom flap will automatically be released against the outlet (15) and indicate to the control, via the bottom flap, that a new loading cycle should be started. 6. If there is insufficient room in the intermediate hopper for all the material, the material will hold the bottom flap down, and a new loading cycle will only be started when the material level has dropped sufficiently to allow the bottom flap to close against the outlet Filter cleaning 1. A filter (21), located between the blower (7) and the hopper loader (10), protects the blower (7) against dust. 2. Immediately before each loading cycle, the filter is automatically cleaned by the blower reversing its rotating direction. This process also cleans the bottom flap (13).

7 Rev. 03 Con-Evator Page 6 2a. If a blow-back valve (80) has been fitted, the blower will not reverse its rotating direction, only the position of the valve will switch so to utilize the outlet air of the blower for filter cleaning. 3. The air that is forced down through the hopper loader will be sent out through the base filter (11). The filter will catch any dust/particles that would otherwise be blown into the ambient air.

R2382

23 Rev. 03 Con-Evator Page Adjustment of the suction probe In order to achieve maximum and consistent conveying it is important that the suction probe has been adjusted correctly. 1. Press the suction probe down into the granules. 2. Loosen the finger screw (46) to release the suction probe (14) from the outer tube (16). 3. While the Con-Evator is conveying, adjust the suction probe and the outer tube to each other until consistent and uniformed conveying has been established. 4. Tighten the finger screw (46) to secure the suction probe and the outer tube in the adjusted position Fig R Adjusting the bottom flap During normal operation the bottom flap should not be adjusted unless it fails. See section 6.3 and 6.6 Maintaining the bottom flap. 4.6 Start Turn the main switch to position 1. The machine will start after approx. 20 seconds. Before starting: see section 4.1 about machine settings, if required. 4.7 Operation 1. Once the Con-Evator has been started, operation is fully automatic (usually in batch processes as the intermediate hopper will occasionally be full) as the bottom flap acts as level control starting and stopping the loading cycle. 2. To ensure maximum performance and life of the machine, proper maintenance should be strictly observed. See section 6.0 Maintenance. 4.8 Stop 1. Stop the Con-Evator by turning the main switch at the control to position 0, or push the reset/stand-by button.

25 Rev. 03 Con-Evator Page Remove the conveying hose from the suction probe. 2. Press the filter holder (56) over the inner and outer tube (14) (16) of the suction hose. Check that the O-ring (57) has been fitted correctly. 3. Fit the cartridge filter (58), the disc (59) and the star handle (60) on filter holder (56). 4. Fit the conveying hose on the inner tube (14) R Installing the line clearing valve It is recommended to install a line clearing valve at vertical lifts exceeding 3 metres for LT-I 3 and LT-I 5, and 5 metres for LT-I 6. The line clearing valve prevents material which is in the vertical conveying hose during conveying from falling back and becoming stuck in the hose when conveying stops. By the end of each conveying cycle the line clearing valve admits air into the conveying hose at the point just above the suction probe. The line clearing valve facilitates start of a new conveying cycle, as no mass of compact material is stuck in the pipes. 1. Fit the T-pipe (61) near by the suction probe (14). 2. Fit the conveying hose (2) on the T-pipe (61). 3. Fit the line clearing valve (45) on the T-pipe (61). 4. Connect compressed air supply 4-10 bar to the connecting branch (62) of the line clearing valve. 5. Wire (63) between line clearing valve and control, follow the diagram. OBS! For reason of weight the line clearing valve should be fitted at an appropriate location e.g. a wall. R1197

26 Rev. 03 Con-Evator Page Installing the Teflon-coated bottom flap A Teflon-coated bottom flap is used where the conveyed material has a tendency to stick to the bottom flap, due for instance to static electricity. Granular pellets stuck to the bottom flap may impede the full closure of the bottom flap, thus causing the hopper to leak at the bottom and preventing the generation of vacuum. 1. Turn off the machine by turning the power switch to position Disconnect the mains voltage. 3. Dismount the Con-Evator from the processing machine. 4. Turn the machine upside down or sideways and dismount the bottom flap by removing the screw and the disc (66). 5. Clean of dust and soil from the assembly roller (67). 6. Fit the Teflon-coated bottom flap (51) on the assembly roll (67), the Teflon-coated side facing the outlet branch. To adjust the bottom flap dislocate the flap in the longish hole until the outlet branch is fully covered. R Adjust the spring function of the bottom flap, if required. See section Install the Con-Evator on the processing machine and connect to mains voltage.

27 Rev. 03 Con-Evator Page Fitting the alarm lamp 1. Turn the main switch to position 0 and unplug blower. 2. Remove the front cover of the control (35). 3. Remove blind plugs (68) from the top face of the control. 4A. Fit alarm lamp (44) on the bracket in the free assembly holes. 4B. Fit alarm lamp (44) on the top face of the control in the free assembly holes. 4C. Fit alarm lamp (44) on the bracket in the free assembly holes. 5. Wire in the control follow the diagram. 6. Fit the front cover (35). R2379

28 Rev. 03 Con-Evator Page MAINTENANCE - SVR The filter should be checked and cleaned at least once a week. A worn filter must been replaced. 6.1 Maintaining the air filter and the base filter Note!
