- 6 - Installation External Wiring DANGER Hazardous voltage. Will cause death, serious injur y, electrocution or propert y damage. Disconnect all power before working on this equipment. NOTE Before runnin g motor, see Initial Start. Starting and overload control devi ces must be matched to motor rating. For safety or convenience they may need to be[...]

- 7 - Installation Angular Alignment Hold each shaft at maximu m end float. Rotate both shafts together, and measure b etween matching points at the outside diameter of the coupli ng faces for the top, bottom and both sides. Use two indicat ors because of possible axial shaft movement. Read difference of variation between them. Align shafts so that[...]

- 8 - Installation Hot Alignment It is possible for the motor shaft height to change relative to the driven equipment and this should be compensated for during the alignme nt procedure. Heat from driven equipme nt can al so cause horizontal misalignment. WARNING Rotating parts. Can cause serious injury. Disconnect and lock out power before working [...]

- 9 - Installation Doweling Doweling the moto r (and driven unit) accomplis h es the following: 1. Restrict s movement. 2. Eases realignment if motor is removed from base. 3. Temporarily restrains the motor, shoul d mounting bolts loosen. Inserting Dowel Pins The following procedure is recomme nde d: a. Check the alignment after the unit has been i[...]

- 11 - Operation Initial Start CAUTION Do not exceed nu mb er o f Siemens specified hot and cold starts per hour. Will cause overheating. Allow time between starts to permit stator windings and rotor cage to cool. After installation is completed, but before motor is pu t in regular service, make an initial start as follows: 1. Check that motor, sta[...]

- 12 - Operation Trouble Shooting Between regular maintenance inspe ctions, be alert for signs of motor trouble. Comm on symptoms are listed in the following table. Correct any trouble immediately an d AVOID COSTLY REPAIR AND SHUT DOWN. TROUBLE POSSIBLE CAUSES CORRECTION Usually line trouble. Singl e phasing at starter. Check power source. DO NOT c[...]

- 13 - Operation Trouble Shooting TROUBLE POSSIBLE CAUSES CORRECTION Open stator windings. Disconnect motor from load. Check idle amps for balance in all three phases. Check stator resistance in all three phases for bala nce. Air Recirculation. Check air intake and exhaust for obstructions. Check air inlet temperature. Over voltage/under voltage. C[...]

- 14 - Maintenance Preventive Maintenance Motors are designed to give many years of reliable service with a minimum of attention. Trouble-free operation cannot be expected if p roper maintenance is postponed or negl ecte d. Provide proper maintenance on the equipm ent. Follow carefully the instructions containe d herein. Be certain personnel review[...]

- 15 - Maintenance Hazardous Location WARNING Explosion or fire. Can cause death, serious injur y or pr opert y damage. Do not modify or change any motor accessories, which are not suitable for the area classification. Any part replacements are accurate duplicates of the original to maintain the hazardous area classificati on. Consult manufacturer [...]

- 16 - Maintenance Temperature Electrical apparatus operatin g under normal conditions becomes quit e warm. Although som e places may feel hot to the tou ch, the unit may be within limits. If checking total temperature by winding resistance or imbedd ed detector (RTD), the total temperature should not exceed the follo wing: When operating at full l[...]

- 17 - Maintenance Rotor Cleaning Remove rotor. Inspect and clean. Stator Cleaning Micalastic™ form wound VPI (vacuum pressu re impregnated) insulated coils may be cleane d with solvent using lint free clot hs or steam cleaned with low-pressure steam, then the e ntire stator oven baked at 170 °F for 6 hou rs and then 245°F for 12 hours. The sta[...]

- 18 - Maintenance Electric Strip Heater Drying 1. Remove bearing housing s. 2. Remove rotor. 3. Direct a fan on stator to carry away the moisture. 4. Attach temperature i ndicators to winding and apply heat as specified in the Insulation Drying Temperature table and follo w procedures described for drying insulation. 5. Radiant type heaters are no[...]

- 19 - Maintenance Insulated Bearings One or both bearings m ay be insulated to prevent shaft currents from pitting bearing surfaces. The insulation is located at the joint between the bearing housing or bracket a nd the bearing. Insulat ed bearings are designated by an instruction plate on the bearing housing. Check periodically to be sure the ins[...]

- 20 - Maintenance At the first sign of oil discoloration or contamination, replace with new oil. Rapi d discoloration is caused by bearing wear, often from vibration or thrust. Chang e oil as required to keep cle an. When assembling the bea ring, it is possible to foul the rings so that they will not turn freely. Check ring operation by rotating s[...]

- 21 - Maintenance Sealing Parts Even though joints may seem to match perfectly, minute clearances exist through which oil may leak. Sealant should be ap plied to the mating surfaces of parts where oil is present to prevent seepage of oil. Sealant should be applied as follo ws: 1. Surfaces shall be clean of dirt, grease, and oil sealant. Use a non-[...]

- 22 - Maintenance Sleeve Bearings CAUTION Maintain proper oil lev el. Failure to do so may cause improper lubric ation of motor resulting in damage to the equipm ent. Follow lubrication instructions carefully. Avoid adding oil while unit is running. Motors with sleeve bearings are shipped without oil. A rust-inhibiting film is applied at the facto[...]

- 23 - Maintenance To Replace Antifriction Bearings 1. Remove bolts holding end caps to housi ngs. 2. Remove bolts holding bearing housin gs t o yoke. 3. Remove bearing housing s. 4. Remove the bearing with a puller. See Figure 6. 5. Check shaft and housing diameter for prop er size with micrometer. 6. Heat the new bearing in an oven (200°F). Whil[...]

- 24 - Maintenance Protect the shaft end with a cap. If bearing is reusable, make certain the puller applies pressure a ga inst the bearing inner race only. If puller will not hook the bearing inner race, fabricate a split bushing an d install it between the bearing and the puller h ooks. Figure 6. Removing Bearing with a Puller Sleeve Bearing When[...]
