Section 9. Electrical Information If supplied with a 208/230/460V 3-phase motor, the connection diagrams on the outside of the motor for low voltage, 230V or high voltage, 460V. This motor connection is also rated for 208V. As any standard motor is rated for +/-10% of voltage variation, this motor will operate properly, within ratings, at 208, 220, 230, 240, 440, 460, and 480V, 3- phase supply. There are other motor configurations including single phase 115V & 230V. If you are unsure of the correct voltage or phase, contact the factory before applying line voltage. If the standard motor is intended for 208V line usage, some caution is advised. If your motor is a 230V motor, and your 208V line voltage drops to 207 Volts (a drop of only ½%), the motor will be operating at -10% in a marginal region. Wiring runs and actual 208 voltages become very important. If your line voltage varies (due to loads elsewhere in the system, etc.) you may have an advantage by ordering as an option a specific 208V +/-10% motor. To reverse the direction of rotation on a 3-phase motor, reverse any two of the three power leads to the motor. On single-phase motors, see wiring diagram on motor. Field Changes in Voltage: Advance Lifts’ standard electrical supplied is 230V, 3-phase unless otherwise specified. Any field change in supply voltage would entail the following changes. 230V to 460V A. Change transformer primary connections to 460V. B. Change overload protection to proper value as per currents in motor tables. Order new overload; adjust new overload to motor full load current setting. Insure the overload is set to “manual” reset, not “automatic” to insure the equipment cannot re-start automatically. C. Change motor connections for high 460V. D. Change plug and receptacle for power, if required. 460V to 230V A. Change transformer primary connections to 230V. B. Change overload protection to proper value as per currents in motor tables. Order new overload; adjust new overload to motor full load current setting. Insure the overload is set to “manual” reset, not “automatic” to insure the equipment cannot re- start automatically. C. Change motor connections for low 230V. D. Change plug and receptacle for power, if required. IMPORTANT: When changing voltages, insure motor rotation is correct. P 9-1

SECTION 11. TROUBLESHOOTING A. Equipment does not rise; pump is running: (see also Section M) 1. The motor rotation may be reversed. See the installation procedure on how to jog the motor to check for proper rotation. If the lift has been installed for some time and the motor is 3-phase, it is possible that the plant wiring “upstream” has been changed during plant maintenance or alteration, and the motor is now running reversed. A hydraulic pump can only run reversed for a short time (possibly 10 to 20 seconds) without causing permanent pump damage. 2. Motor may be single phasing. Check wiring and overloads to be certain that each three-phase line is present at the motor. 3. Voltage at motor terminals may be too low to run the pump at existing load. Check voltage directly at motor terminals while pump is running under load. (Reading source voltage with the pump idling will not give accurate results). Inadequate or incorrect wiring can starve the motor of voltage and current and will show up at the motor terminals when the motor is drawing the higher current that is required while motor is loaded. 4. Check for a hydraulic hose leak or pinching, and correct as necessary. 5. Check under the pump coupling to insure the key way has not slipped off the pump shaft. 6. Check for oil shortage in the reservoir and correct by filling the reservoir. Refer to “Fluid Recommendations” in this manual for the correct fluid for your ambient temperature. 7. The suction filter in the reservoir or the pressure line filters in the pipe outlet of the power unit or the breather cap on the reservoir may be clogged. Clean as required. 8. Check if the load is exceeding equipment ratings causing the relief valve to bypass the fluid back to the reservoir. Never change the relief valve setting, these are 100% tested, adjusted, and locked at the factory. Any change in the relief valve setting could cause your equipment either not to lift its capacity, or cause dangerous forces in the equipment, and void your warranty. 9. Check that the suction line fittings are not loose, causing the pump to pull in air instead of fluid. Check for a hairline crack on the suction port of the pump. The clear suction line should stay full of oil at all times, clear, and no air. Check that the natural curve of the suction hose in the reservoir doesn’t cause the filter to rise out of the fluid. Re-install the suction line without rotating it and the tension of the hose will free the suction hose to lie against the reservoir wall and the filter to lay flat near the reservoir bottom. If you have the short round “pancake” type of filter with the filter screen on the bottom of the filter, insure that it does not rest against the bottom of the reservoir, as this will restrict the flow to the pump. P 11-1
SECTION 11. TROUBLESHOOTING (Continued) 10. The down solenoid may be energized due to incorrect wiring, or mechanically stuck open, bypassing fluid. A. Check the wiring. Hold a non-magnetized screwdriver to the top of the down solenoid coil and press the up button. If you can feel magnetism, the wiring is faulty. B. Lightly tap the down solenoid to seat it properly. Do not bang it hard, as internal stem parts may be permanently damaged. The solenoid coil can be removed, and the down valve removed for cleaning as explained in the hydraulic “Component Information” section. C. Disconnect the pressure line from the valve manifold to the equipment. Place a pressure gauge at the valve output, using high-pressure reducers. Press the up button in a short jog and read the pressure. Press the down button to relieve the pressure. If the system will not put out the pressure indicated on the hydraulic diagram, the trouble is either the valves or pump. If a load is not available, then the maximum hydraulic system pressure can be checked on a gauge by raising the unit to its full height momentarily against its physical stops. Proceed to step 11 to determine which place the trouble exists. 11. The hydraulic pump may be inoperative. Disconnect a hydraulic line at the power unit, use a large bucket (5-gallon) and run the pump a short time. If no flow appears either the pump or pump motor coupling inside motor mounting flange is defective, or pump rotation is reversed. Connect a pressure gauge to the outlet of the pump, through a high-pressure tee and bleeder valve with hose to a bucket. Slowly turn the bleeder valve and see if the produces specified pressure. Do not close the valve all the way as the pressure buildup of a good pump could cause the pump to explode. If the pump does not put out the required pressure, then the problem is in other areas, such as a down solenoid valve leaking fluid back to the reservoir, allowing pressure not to be built up in the system. If the pump will not put out the required pressure, replace the pump. 12. Repeated continuous type operation of the equipment may cause thinning of oil due to heat buildup. Feel the side of the reservoir to check the temperature of the oil. The equipment is intended for dock type operation, not elevator type operation that would make the equipment cost several times as much. The thin oil can cause the equipment not to rise, and in time, ruin the hydraulic pump. This type of operation could void the warranty considerations. B. Equipment raises too slowly: 1. Small amounts of foreign material could stick in the down solenoid, bypassing some of the fluid. Lower equipment and clean the down solenoid valve. 2. Foreign material clogging the suction filter, breather cap, pressure line filter, or a hose that is pinched. See A-4, 5, 6, 7 and 9. 3. Low motor voltage. See A-3. 4. Load exceeding equipment ratings. See A-8. 5. Oil may be too thick (ambient temperature) for proper operation. Refer to “ Fluid Recommendations”. P 11-2
