OPERATING NOTES:

  • Jog the electric motor once and verify that the electric motor is rotating in the same direction as the arrow on the electric motor housing. If the direction is incorrect, reverse two of the three leads on a 3- phase electric motor.
  • VT- SERIES POWER UNITS are tested and pressure control valves are factory preset. If adjustments are needed, follow the procedure below:
    Begin adjusting pump compensator to increase the pressure gradually. NOTE: Do
    not exceed maximum pressure setting as stated on unit nametag. The maximum pressure setting is a function of the electric motor H. P. and pump combination. Contact your Advance Motion Control representative for assistance.
  • If pump fails to prime, vent pump discharge to atmosphere to establish fluid flow.

MAINTENANCE NOTES:

  • Reservoir temperature should not exceed 150°F. System reliability and component service life will be reduced when system is operating at higher temperatures. Always take an oil temperature reading at the reservoir, not at a component or any of the tubing.
  • Clean fluid = system reliability and longer component service life, change filter element whenever filter indicator indicates dirty element condition.
  • It is recommended that every 4,000 operating hours or once a year, whichever occurs first, the filler/ breather cap and suction strainer should be replaced.

FLUID RECOMMENDATIONS:

  • Premium quality hydraulic oil with a viscosity range between 150-250 SSU (30- 50 cst.) at 100°F. (38°C.). Normal operating viscosity range between 80- 1000 SSU (17-180 cst.). Oil should have maximum anti- wear properties, rust and oxidation treatment.
  • Advance Motion Control offers an oil sampling kit which can be used to ascertain the condition of the system fluid.
  • Consult Advance Motion Control when the system fluid is exceeding 150°F (71°C.) during operation.

FILTRATION :

For maximum pump and system component life, the system should be protected from contamination at a level not to exceed 125 particles greater than 10 microns per milliliter of fluid. (SAE Class 4/ISO 16/13.) Due to the nature of variations in pump inlet conditions, fluid acceleration losses, system aeration, and duty cycle must be carefully considered before specifying suction line filtration. Contact your Advance Motion Control representative for assistance.

MAINTENANCE SUGGESTIONS:

  1. Set up a regular schedule for checking the oil temperature, sampling the oil and replacing the filter.
  2. Inspect filter elements that have been removed from
    the system for signs of failure which may indicate that the service interval should be shortened and of impending system problems.
  3. Never reuse in the system any fluid that has leaked out.
  4. Always keep the fresh fluid supply covered tightly.
  5. Use clean containers, hoses, and funnels when filling the reservoir. Use of an Advance Motion Control filter cart is highly recommended.
  6. Take precautions to prevent entry of dirt into
    components that have been temporarily removed from
    the system.
  7. Make sure that the clean out cover, filler cap, and through hole accessories are properly fastened to the reservoir.
  8. Do not run the system unless all normally provided filtration devices are in place.
  9. Keep the system clean. A thick layer of dirt acts as an insulator. It will prevent the hydraulic system from getting rid of heat.
