Specification

Hydraulic fluid for compact power module

Mineral oil based hydraulic fluids suitable for hydraulic systems can be used; they should have physical lubricating and chemical properties as specified by:-

  • MINERAL OIL BASED HYDRAULIC FLUIDS HL (DIN 51524 part 1)
  • MINERAL OIL BASED HYDRAULIC FLUIDS HL P (DIN 51524 part 2)

Fluid viscosity, Temperature range of the operating fluid, Ambient temperature

The fluid viscosity should remain within the range 10 to 300 Centistokes; recommended 15 to 120 Centistokes.

Permissive cold start viscosity is maximum 2000 Centistokes.

The fluid temperature should remain within the range -15°C and 80°C (5°F and 116°F)

Ambient temperature -15°C +40°C (5°F and 104°F)

Fluid cleanliness requirements and maintenance

We recommend a cleanliness of the operating fluid according to ISO 4406 Class 19/17/14 or cleaner.

All components of the hydraulic circuit, including hoses and actuators, must be flushed and cleaned before assembling, because the compact power module has a suction filter only.

The hydraulic fluid should be replaced after the first 50 hours and then every 1000 hours, or at least once a year.

Wiring and starting-up

The wiring between battery and electric motor should be selected in order to avoid excessive voltage drop (recommended less than 1V)

It is strictly forbidden to allow the backwards rotation of the pump even at the first starting to prevent reverse rotation, the wiring polarities must be correctly connected.

Caution: when energized, the surface temperature of the electric motor could reach temperature levels of 60-80°C (14-116°F) care should be taken to avoid any accidental contact of people with the motor surface.

A.C. Motors

The tolerances on the nominal voltage are:-

Single phase motor: 230V +/-5%
Three phase motor: 230-400V +/-10%
Protection degree: IP54 (protection against dust and water splash)
Insulation class: F (155°C) (31JOF)

All motors are painted aluminium alloy die cast.

Note: Standard single-phase motors have a permanently connected run capacitor.

D.C. Motors

For each motor a diagram is shown that enables the customer to select the right pump displacement needed for the required flow and working pressure.

To be sure of selecting the best electric motor for the application, also the duty cycle must be verified.

Following are the definitions of the type of duty cycles:-

S2 = Short time duty cycle: Indicates the number of minutes the motor can operate before reaching the maximum allowable temperature, after this time the motor must cool down until the ambient temperature is reached.

S3 = Intermittent duty cycle: Indicates the maximum time percentage (%) based on 10 minute period within the motor can run until reaching the maximum allowable temperature. For example, an S3 value of 15% = 1.5 minutes running time every 10 minutes period for 8.5 minutes the motor is switched off.

The S2 and S3 values are related to the current draw. On the label of motor are indicated the S2 and S3 values referred to the nominal power of the motor.

To check the S2 or S3 value at different conditions is necessary to find the value of current in the motor-pumps diagram and related it with the represented list.

For each motor a diagram is shown that enables the customer to select the right pump displacement needed for the required flow and working pressure.

To be sure of selecting the best electric motor for the application, also the duty cycle must be verified.
