Mounting dimensions are shown in Figure 2-1 2. 2 2. 2. 1 2. 2. 2 2. 2. 3 Dc Motor, front view Dc Motor, Side view WIRING THE PUMP electrical connections are shown in Figure 2-2 Wiring to the ac motors should be 16 aWG stranded wire with insulation rated for 300 v max and 105ºc. the Dc pump motors and all low level switches may be wired with 18 aWG stranded wire cable. figure 2-2b(ac) Cantoni & ABB Motors FAN CAPACITOR L1 L2 GNd U2 Z2 Z1 U1 figure 2-2c (Dc) Moto Technica 1ph Motors W2 U2 V2 FAN ac Motor, front view ac Motor, Side view figure 2-2a (Dc) U1 V1 W1 SHAFT figure 2-2d (ac & Dc) COMMON NC top view, Dc and ac LOW LEvEL SWITCH WIRING SCHEMATIC Figure 2-1 2-1 Figure 2-2 Tri-Lube Grease Pump Package User Manual 2. 3 FILLING THE RESERvOIR 2. 3. 1 the reservoir should be filled with clean air free grease of the type recommended by the machine builder and having an nlGI grade number consistent with the ambient operating temperature of the equipment (grease must be pumpable at the lowest anticipated operating temperature). 2. 3. 4 L42255 for subsequent re-filling, unless the reservoir has been allowed to run dry or air was pumped into the reservoir, it will not be necessary to remove the yellow plug or fill above the vent hole. 2. 4 2. 4. 1 CAUTION do not fill the reservoir with grease heavier than NLGI #2. For temperatures below -5OF (-20OC), use NLGI #1 or lighter grease. 2. 3. 2 filling is accomplished by connecting a suitable transfer pump to the fill fitting in the front of the pump housing (See Figure 2-3). Before connecting the transfer pump, make sure that both the lube fitting and the coupler are clean and that the hose and transfer pump are full of clean grease that is free of air. PURGING THE PUMP ANd SYSTEM OF AIR operate the pump with the main line disconnected until grease free of air is seen at the pump outlet. fill and purge system lines and divider valves following the procedures outlined in trabon Bulletin l30103. once all lines and dividers have been purged free of air, reconnect pump to mainline. 2. 4. 2 2. 4. 3 1 3 vent Hole 2 figure 2-4a Fill Fitting Pump Position Plug Figure 2-3 2. 3. 3 for the initial filling, or if the reservoir has been allowed to run dry, removing one of the pump position yellow plugs from the pump body will facilitate expelling air from the body and reservoir. Slowly start to fill the reservoir until grease free of air flows from the open pump position. at this point, stop the transfer pump and re-install the yellow plug. after the plug is installed, fill slowly until the follower seal is slightly above the vent hole in the reservoir tube. this will allow air remaining below the follower to escape. When grease free of air is seen at the vent, stop filling. figure 2-4b 3 4 figure 2-4c Figure 2-4 2-2 Tri-Lube Grease Pump Package User Manual 2. 5 AddING PUMP ELEMENTS CAUTION To avoid personal injury or severe internal damage to the drive-train, or pump element, these procedures must be followed carefully. 2. 5. 1 2. 5. 2 2. 5. 3 Disconnect power to the pump motor. pull out pump piston 2 until it extends approximately 1-1/8" (29 mm) from end of cylinder to end of mushroom head. Insert element into housing at approximately a 15 degree angle as shown in figure 2-4b. NOTE: If pump is full of grease, it will be necessary to clear a path through the grease using a clean screwdriver. 2. 5. 5 2. 5. 6 2. 5. 7 rotate element down (figure 2-4c) engaging mushroom head between cam 3 and retracting ring 4. tighten element 18-22 fl-lbs (25-30 n-m). Do not over torque as housing threads will be stripped. [. . . ] If grease is too heavy for the temperature conditions, empty reservoir and refill with grease of the correct nlGI grade number (refer to section 2. 3). If grease contains air pockets and pump is air bound, empty reservoir and refill with grease that is free of air (refer to section 2. 3). 5. 2 5. 2. 1 5. 2. 2 LOW LEvEL SWITCH dOES NOT SIGNAL LOW LEvEL Make sure that level switch is properly wired (see figure 3-1) and correct any problems found. Make sure that the follower tracks the drop in grease level to the bottom of the reservoir. If follower appears stuck in reservoir at mid travel, there is most likely a pocket of air between the bottom of the follower and the top of the grease column. [. . . ]
